This conversion is worth doing for one reason and not for another, and the difference matters. The good reason is a requirement: an editor, a printer, a design tool or an upload form that accepts PNG and nothing else. PNG is lossless, so the copy you get is pixel-exact against the JPEG you started with, and every subsequent save in that workflow costs nothing in quality. That is a genuine benefit and the reason PNG-only pipelines exist.
The reason not to do it is the belief that converting to PNG improves the image. It cannot. JPEG compression discards information when the file is first saved, and those decisions are permanent — the softness around edges, the blocking in flat areas, the faint halos around text are all baked into the pixels. PNG stores those exact pixels perfectly. You end up with a considerably larger file containing precisely the same flaws, preserved losslessly.
Size is the practical consequence. A photograph is the content PNG is worst at: it has no repeated flat regions to exploit, so a PNG of a photo is routinely several times the size of the JPEG it came from. That is fine for a file passing through an editing step and a poor idea for anything being published, emailed, or stored in bulk.
How to convert JPG to PNG
- 1
Add your JPGs
Drop one file or a batch. Decoding and re-encoding both happen in your browser, so nothing is uploaded at any point.
- 2
Select PNG as the output
Choose PNG from the format options. The quality slider switches off, because PNG is lossless — there is no quality setting to make.
- 3
Download the PNG copies
Each file keeps its name with a .png extension. The pixels are identical to the decoded JPEG, which is exactly what a PNG-only workflow needs.
- 4
Expect a larger file
A PNG of a photograph is normally several times the size of the JPEG. That is the format working as designed, not a problem with the conversion.
Pro tip: Use PNG as a working format, not a delivery one. If the image is going into an editing pipeline where it will be saved repeatedly, converting to PNG first is genuinely valuable — it stops each save adding another layer of JPEG loss on top of the last. When the work is finished, convert back to JPEG or WebP for delivery. Treating PNG as the format you publish photographs in is how sites end up with pages several megabytes heavier than they need to be.
Troubleshooting: If the PNG looks exactly as flawed as the JPEG did, that is correct and expected — conversion preserves pixels, it does not repair them. Nothing can undo JPEG compression after the fact. If the file is enormous, that is PNG storing photographic content losslessly; convert to WebP instead if you want a smaller lossless-feeling result for the web. If you were hoping to add transparency, note that converting does not create an alpha channel — the JPEG had no transparency to recover, so you would need to remove the background separately.
Going the other way to reduce size, Convert PNG to JPG. For modern formats that keep transparency at a fraction of PNG's size, Convert WebP to PNG and Convert AVIF to PNG cover the reverse conversions. If the destination is a document, PNG to PDF Converter explains what happens on the way in. Any other pair is handled by the full Convert Image tool.
Frequently asked questions
How do I convert JPG to PNG?
Add your JPG files above, choose PNG as the output format, and download. The quality slider disables itself because PNG is lossless — there is nothing to set. The resulting pixels are identical to the decoded JPEG.
Does converting JPG to PNG improve quality?
No. JPEG discards information permanently when it is first saved, and converting to PNG stores those already-degraded pixels losslessly. You get a larger file containing exactly the same artefacts. Nothing can recover detail a JPEG has already thrown away.
Why is my PNG so much bigger than the JPG?
Because PNG is lossless and photographs are the content it handles worst — there are no large flat regions for it to compress efficiently. A PNG of a photo being several times the size of the JPEG is normal and expected, not a sign that something went wrong.
When should I convert JPG to PNG?
When something in your workflow requires PNG, or when the image will be edited and saved repeatedly and you want to stop JPEG loss accumulating with each save. Convert back to JPEG or WebP for delivery — PNG is a good working format and a poor publishing one for photographs.
Are my photos uploaded when converting?
No. Everything runs inside your browser on your own device — nothing is uploaded, stored, or logged, and the tool works offline once the page has loaded.
