How to convert JPG to PNG

Step 01

Drop your JPG images into the box above. You can add multiple files at once.

Step 02

Adjust the quality slider if available — higher quality means larger files.

Step 03

Click Convert. Each image is processed in your browser using the canvas API.

If you uploaded multiple images, they're packaged into a ZIP and downloaded automatically.

Converting JPG to PNG is the opposite trade to PNG-to-JPG: you give up small file size to gain a lossless, transparency-capable image. The honest caveat first — converting a JPG to PNG cannot add back detail the JPG already threw away. What it does give you is a format that will not lose any more quality on future edits and saves, plus the ability to add transparency. The conversion happens right in your browser, so your JPG stays on your device the whole time.

Good reasons to convert JPG to PNG

The most common one is editing: every time you save a JPG it re-compresses and degrades a little, so designers convert to PNG to "freeze" the current quality before working on an image. PNG saves are lossless, so repeated edits do not accumulate damage.

Other good reasons: a tool or platform that only accepts PNG, a need to add a transparent background later, or wanting crisp, artefact-free edges for a graphic that will sit on a coloured layout.

What you will and will not gain

You will gain a lossless container and the option of transparency. You will not gain back the fine detail or the faint compression artefacts already baked into the JPG — those are permanent. A PNG made from a JPG looks identical to the JPG; it just will not get any worse from here.

Expect the PNG file to be noticeably larger than the JPG, often several times bigger, because PNG does not discard data the way JPG does.

Frequently asked questions

Does converting JPG to PNG improve the quality?

No — it cannot restore detail the JPG already discarded. It preserves the current quality losslessly so future edits and saves do not degrade it further, but it will not make a blurry JPG sharp.

Why is my PNG so much bigger than the JPG?

PNG is lossless and stores full pixel data, while JPG aggressively discards information to stay small. A larger PNG is expected and normal after this conversion.

Can I add transparency after converting to PNG?

PNG supports transparency, so the format can hold an alpha channel — but the conversion itself does not remove the existing background. You would erase the background in an image editor afterwards.

Is the conversion private?

Yes. Your JPG is converted to PNG locally in your browser and is never uploaded to a server.
