About the JPG to PNG Converter

Convert JPG to PNG online, free, with nothing uploaded to a server. Drop in a single JPEG or a whole folder of them: this converter will change JPG to PNG one file at a time, or batch convert JPG to PNG in bulk, entirely inside your browser using the Canvas API — your files never leave your device. PNG is lossless, so the image you download keeps every pixel it had going in and will not pick up new compression artefacts no matter how many times you re-save it, which is why designers turn a JPG into a PNG for logos, screenshots, product shots and anything with text or sharp edges. Switch on Remove background and the tool erases the backdrop to give you a genuinely transparent PNG rather than a white box. Bulk conversions come back as individual downloads or as one zip.

JPG to PNG Converter FAQ

What is the difference between JPG and PNG image formats?

The main difference between JPG and PNG lies in compression type and image quality. JPG (or JPEG) uses lossy compression, which reduces file size by permanently removing some image data. This makes JPG ideal for photographs and large images where slight quality loss is not noticeable. PNG, on the other hand, uses lossless compression, meaning it preserves every pixel of the original image without quality degradation. PNG also supports transparent backgrounds (alpha channel), making it perfect for logos, graphics, screenshots, web design elements, and digital artwork. If you need high-quality visuals, sharp text edges, or transparency support, using a JPG to PNG converter is often the better choice.

Will my PNG have a transparent background?

Only if you switch on Remove background before converting — and it is worth understanding why. A JPG file has no alpha channel, which means it stores no transparency information at all. Simply changing the file extension or running a plain JPG to PNG conversion therefore cannot produce a transparent PNG; you get the same picture, solid background and all, in a different container. Any converter claiming otherwise is not telling you the truth. What this tool does when you tick Remove background is genuinely detect the subject and erase everything behind it, then write the result into the PNG alpha channel. So if you came here looking for a JPG to PNG transparent conversion, or for a background eraser to delete the backdrop from a photo, that switch is the thing you want. Flat backdrops such as a white studio sweep, a screenshot or a solid-colour logo are cleared instantly. Busier photographs take a few seconds longer because the subject has to be identified first. Either way the work happens inside your browser, so the image is never uploaded anywhere.

Can I batch convert JPG to PNG, or convert multiple files in bulk?

Yes. Batch JPG to PNG conversion is built in. Drop in as many JPG or JPEG files as you like — up to thirty at a time — and the converter works through the queue one file at a time, showing progress for each. You can download each PNG individually as it finishes, or grab everything at once as a single zip archive. Bulk conversion is genuinely useful when you need to mass convert JPG to PNG for a set of product images, exporting a folder of screenshots, or converting an entire photo shoot to PNG for editing. Because every conversion runs locally in your browser, a batch of thirty files costs no upload time and no waiting in a server queue. If one file in the batch turns out to be corrupt or is not really a JPG, only that row is marked as failed and the rest of the batch still completes.

Is JPEG the same as JPG? Which one does this tool accept?

JPG and JPEG are the same image format with two different file extensions. The format is properly called JPEG, after the Joint Photographic Experts Group that created it, but early Windows versions limited file extensions to three characters, so .jpeg was shortened to .jpg and both spellings stuck. There is no quality difference, no structural difference, and no conversion needed between them. This converter accepts both .jpg and .jpeg files interchangeably, so you can use it as a JPEG to PNG converter just as readily as a JPG to PNG converter, and mix both extensions in the same batch.

Is this JPG to PNG converter really 100% private?

Yes. This online JPG to PNG converter runs entirely in your browser using the HTML5 Canvas API. Your files are never uploaded to a server, which means no cloud storage, no third-party access, no image tracking, and no data collection. Because the conversion happens locally on your device, your images stay completely private. This is also true of background removal: the subject detection runs on your own machine rather than on somebody else’s server, which is unusual — most background removers require you to upload the photo first. Once the page has loaded, you can even convert JPG to PNG without an active internet connection.

Will converting JPG to PNG improve image quality or make it HD?

No, and it is worth being clear about this because a lot of pages imply otherwise. Converting JPG to PNG cannot restore detail that JPG compression already discarded, and it cannot add resolution — a 600×400 JPG becomes a 600×400 PNG, not an HD or high-resolution one. No format conversion can invent pixels that were never recorded. What conversion does do is stop the bleeding: PNG is lossless, so from that point on the image will not degrade further no matter how many times you edit and re-save it, whereas each additional JPG save compounds the artefacts. So convert JPG to PNG to preserve the quality you still have, not to recover quality you have already lost. If you genuinely need a larger image, you need an upscaler, which is a different kind of tool.

Why should I convert JPG to PNG instead of keeping JPG?

There are several good reasons to convert JPG to PNG: you need a transparent background for a logo or overlay, you are designing graphics where sharp edges and clean text matter, you want to stop further compression damage during repeated editing, or a website, app or marketplace specifically requires PNG files. PNG is widely used in web development, UI and UX design, digital branding and professional editing workflows. If quality and edge clarity matter more than file size, PNG is usually the better format. For photographs that will simply be viewed or shared, JPG remains the more economical choice.

Does converting JPG to PNG increase file size?

Usually yes, and often substantially. PNG files are typically larger than JPG files because lossless compression preserves the full image data rather than throwing detail away. For a detailed photograph a PNG can easily be several times the size of the JPG it came from; for flat graphics, logos and screenshots with large areas of solid colour the difference is much smaller, and PNG can occasionally even be smaller. If you need a smaller file, converting to PNG is the wrong move — compress the JPG instead, or use a PNG optimiser after converting. What you get in exchange for the extra bytes is clarity, editing headroom and transparency support.

Can I convert a JPG to PNG at a specific file size, like under 1 MB?

Not directly, and it is worth explaining why rather than pretending otherwise. PNG uses lossless compression, which means there is no quality dial to trade away in exchange for a smaller file the way there is with JPG. The size of a PNG is determined almost entirely by the image content itself — its dimensions and how much fine detail and colour variation it contains. There is no way to produce a compressed PNG at an arbitrary target size on demand. The reliable ways to reduce a PNG are to cut the pixel dimensions before converting, to reduce the number of colours, or to keep the file as a JPG where a quality slider genuinely controls the size. If your goal is simply a smaller image rather than a PNG specifically, a compressor or a resizer will serve you far better than a format conversion.

How do I convert JPG to PNG on Windows, Mac, iPhone or Android?

This converter runs in the browser, so the same page works identically on Windows, macOS, Linux, iPhone, iPad and Android — there is nothing to install and no separate app to find. On mobile, tap the upload area and choose images from your camera roll; the converted PNG saves straight to your downloads. If you would rather use built-in software: on Windows, open the JPG in Paint and choose File then Save as then PNG; on a Mac, open it in Preview and choose File then Export with the format set to PNG. Both work fine for a single image, but neither handles a batch, and neither can give you a transparent background.

Can I convert a logo, sticker or icon from JPG to PNG?

Yes, and this is exactly the case where converting to PNG pays off most. Logos, stickers, icons and other flat graphics suffer visibly from JPG compression: you get faint halos and smeared blocks around sharp edges and lettering. PNG stores those edges cleanly. Better still, logos and stickers are usually sitting on a plain white or single-colour background, which is precisely the case the Remove background option handles instantly — so you end up with a transparent PNG you can drop onto any colour, slide deck or product mockup without a white rectangle around it. For a logo you intend to scale to billboard size, a vector format would be better again, which is what the JPG to SVG tool is for.

Is there a file size limit for conversion?

Since this JPG to PNG conversion tool works entirely inside your browser, the file size limit depends on your device’s available memory and processing power rather than on any upload cap we impose. Most modern devices handle images up to 50MB comfortably, and large images up to 100MB with a slight delay. Because there is no server upload involved, you do not have to worry about platform upload limits, daily quotas or queue times. When converting a large batch on a phone, expect it to take longer than on a desktop — the work is being done by your device.

Do I need to sign up, and are there watermarks?

No sign-up, no account, no email address, and no watermarks of any kind on your converted images. There are no hidden fees, no subscriptions, no premium tier and no daily limit on how many files you can convert. The reason this is sustainable is structural rather than generous: because every conversion runs in your browser, there are no servers processing your images and therefore no per-conversion cost to recover. The tool also keeps working offline once the page has loaded, since nothing needs to reach the network to convert a file.

Is JPG to PNG conversion safe for sensitive or confidential images?

Yes, and this is one of the strongest arguments for a browser-based converter. Because the tool works entirely client-side, there are no server uploads, no file storage, no backups and no tracking. Your images never leave your device, so scanned documents, identity papers, medical images, unreleased product shots and personal photos stay confidential in a way that no upload-based service can match. If you want to verify this rather than take it on faith, open your browser’s network inspector while converting: you will see no request carrying your image.

What happens if the background removal gets it wrong?

Automatic subject detection is very good but not infallible. It performs best when the subject is clearly separated from what is behind it — a product on a plain surface, a person against an uncluttered wall, a logo on white. It struggles most with fine strands of hair, transparent or reflective objects such as glass, and subjects whose colour closely matches the background. If the cut-out is not clean, the practical fix is to start from a source image with better separation, or to convert without background removal and do the masking in an editor where you have manual control. Nothing is destroyed either way: your original JPG is untouched, so you can simply convert again with the option switched off.

Does converting JPG to PNG affect SEO or website performance?

Image format choice affects page speed, and page speed is a ranking factor, so it matters. The rule of thumb is to use JPG for photographic content where smaller files load faster, and PNG for logos, icons, screenshots and anything needing transparency or crisp text. Using PNG for large photographic backgrounds is a common and costly mistake, because the file can be several times heavier for no visible benefit. Whichever you choose, compress the image before uploading it, give it a descriptive filename, and write meaningful alt text. For web delivery specifically, WebP now usually beats both formats on size at equivalent quality.

Is this a free JPG to PNG converter?

Yes, completely free with no limitations. There are no hidden fees, no subscriptions, no premium tiers, no watermarks and no registration. You can convert as many JPG files to PNG as you need, at any file size, as often as you want, including batch conversions and background removal. The tool runs entirely in your web browser using the HTML5 Canvas API, so there are no server-side processing costs or cloud infrastructure to fund, which is why it can stay free permanently rather than as an introductory offer.

How do I change a JPG to PNG without losing quality?

You already are. Because PNG is a lossless format, converting a JPG to PNG never introduces further quality loss — every pixel present in the JPG is carried across to the PNG exactly. There is no quality slider to set and no trade-off to manage, which is precisely why PNG is the sensible working format when you expect to edit and re-save an image repeatedly. The one thing conversion cannot do is undo the compression the JPG had already applied before you got it, since that detail is gone from the file for good.
