How do I convert a JPG to PNG for free?

Upload the JPG and download the PNG. There is no quality setting because PNG is lossless, so the conversion runs automatically in your browser.

Does JPG to PNG conversion improve quality?

No. Detail already discarded by the JPEG encoder cannot be recovered. The PNG is a pixel-exact copy of the JPEG that was decoded, so it stops any further loss from that point onwards.

Why is the PNG file so much bigger than the JPG?

PNG records every pixel without loss, while JPEG stores a close approximation in far fewer bytes. The same photo is typically several times larger as a PNG.

Is the uploaded file sent anywhere?

No. The conversion uses a canvas inside your browser. Your image never leaves your device.

When should I use PNG instead of JPG?

When you need transparency, when the image is a screenshot or graphic with sharp edges and flat colour, or when you are editing in several passes and want to stop the repeated quality loss that a lossy format causes.

JPG to PNG converter

Convert a JPEG into a lossless PNG in your browser. No quality slider to guess at, because PNG does not have one — free, nothing uploaded.

What converting JPG to PNG actually does

A JPEG file does not contain the image your camera recorded. It contains a mathematical approximation of it, and that approximation is decoded back into pixels whenever the file is opened. Converting to PNG takes that decoded result and stores every one of those pixels exactly, with no further approximation.

So the honest description is: PNG conversion freezes the JPEG exactly as it looks right now. It cannot recover detail the JPEG discarded, and the file will be larger. What it does is stop further loss.

Why that matters when you are editing

Lossy formats degrade on every save. A workflow that opens a JPG, adjusts it, saves as JPG, edits again and saves again compounds the damage: each save re-encodes the already-degraded image and adds fresh artefacts, especially around edges and in gradients where banding appears.

Converting to PNG once at the start of an editing session breaks that cycle. You edit and save as many times as you like with no additional loss, then export a final JPG or WebP at the end for delivery. This is the standard intermediate-file approach: lossless while working, lossy only for the last step.

Transparency: the limit of what this conversion can do

PNG supports transparency and JPEG does not, but a JPG does not secretly contain transparent data waiting to be revealed. Any area that looks white in your JPG is white — it is a solid colour, not a transparency. Converting will keep it white.

If you need a background removed, that is an editing job, not a conversion. For cutting a subject out and exporting with a transparent background, use the cropper to frame it and then export as PNG or WebP from the converter.

When PNG is the wrong choice

Publishing photographs on a website — a PNG of a photo can easily be five times the size of the JPEG, and WebP or JPG both look identical while loading faster.
Email attachments — many mail servers cap total message size; converting photos to PNG makes hitting that cap more likely.
Anywhere a JPG or WebP is accepted — the larger file buys you nothing if nobody is going to re-edit it.

Frequently asked questions

Does this conversion lose any quality?

No. PNG is lossless, so the pixels that come out are exactly the pixels the JPEG decoder produced. The only quality difference is the one your JPEG already had.

Why did my file get so much bigger?

Because PNG stores every pixel exactly instead of approximating. That is normal, and it is the price of a lossless working file. Keep the PNG for editing and export a compressed format when you publish.

Will the transparency come back?

No. A JPEG has no transparency to restore. Areas that appear white are solid white pixels.

Can I convert a JPG to PNG on my phone?

Yes — the tool works in mobile Safari and Chrome. Pick the photo from your gallery, and use the maximum width option if the result needs to be a manageable size.

Should I convert to PNG or WebP instead?

WebP gives you lossless quality at a much smaller size, and current browsers all support it. Choose PNG when a specific application or printer requires the PNG format; otherwise WebP is usually the better lossless container today.
