How to Convert JPG to PNG
Worth being straight about this one: converting a JPEG to PNG will almost always make the file bigger, often several times over, and it cannot recover any detail the JPEG compression already threw away. So the reason for doing it matters. The strongest reason is that JPEG loss is cumulative — every time you open a JPEG, edit it and save again, it degrades a little further, and after a handful of rounds the artefacts become obvious. Converting once to PNG stops that clock: from then on every save is lossless, so you can crop, retouch and re-export as many times as you like without further damage. The second reason is transparency. JPEG has no alpha channel at all, so if you plan to cut out a background or composite the image over something else, you need a format that can hold transparent pixels — and PNG can. Beyond that, plenty of tools and platforms simply require PNG. Drop your files onto the panel above, or paste one from the clipboard, and each is decoded and re-encoded losslessly in your browser. Convert as many as you like at once, optionally scale them down with a maximum width, and take them individually or as a single ZIP. Nothing is uploaded to any server.
Add your JPG files
Drag and drop, paste, or click to browse — multiple at once.
Set options if needed
Optionally cap the width to resize while converting.
Download
Save each PNG, or take the whole batch as one ZIP.
JPEG vs PNG
JPEG — small, but lossy
Built for photographs, JPEG discards fine detail to keep files small. The loss is permanent and accumulates with every re-save, and there is no support for transparency.
PNG — exact, with alpha
Every pixel is stored precisely and an alpha channel is supported. Files are larger for photographic content, but nothing degrades no matter how many times you edit and save.
Common Use Cases
Prepare for editing
Convert before a round of edits so repeated saves don't degrade the image.
Remove a background
PNG can hold transparency once you've cut the subject out.
Meet a PNG requirement
Some editors, platforms and print workflows accept only PNG.
Compositing and overlays
Layering images needs an alpha channel JPEG can't provide.
Design handoff
Give a designer a lossless working file rather than a compressed one.
Presentation graphics
PNG avoids the visible artefacts JPEG shows on flat backgrounds.
Archive a working copy
Keep a lossless version alongside the compressed original.
Strip location data
Conversion removes EXIF, including GPS coordinates, before you share.
Tips & Best Practices
Expect a much larger file
PNG is lossless, so a photographic JPEG can grow several times over. That's the cost of stopping further degradation.
Convert before editing, not after
The benefit is preventing future loss. Converting a file you've already re-saved ten times locks in the damage.
It can't undo existing artefacts
Detail JPEG discarded is gone. The PNG faithfully stores whatever was left.
Keep JPEG for the final web export
Edit in PNG, then export to JPEG or WebP when you publish, for the smallest download.
Resize during conversion if you can
Scaling down offsets much of the size increase, and looks better than shrinking later.
Don't convert your whole photo library
For storage, JPEG is the right format. Convert only the images you're actually going to work on.
Troubleshooting
The PNG is much larger
That's expected. PNG is lossless while JPEG is heavily compressed, so a size increase of several times is normal for photographs.
The image still looks compressed
Conversion can't undo existing JPEG artefacts. It prevents further loss but doesn't restore what was already discarded.
My photo has no transparency
JPEG never had any. The PNG supports an alpha channel, but you'll need an editor to actually cut out a background.
The file wouldn't open
Check it's a real JPEG. Files renamed with a .jpg extension but containing something else won't decode.
Frequently Asked Questions
How do I convert JPG to PNG for free?
Drop your JPEG files above and each is converted to lossless PNG instantly. Download them individually or as a ZIP — free, no signup.
Are my images uploaded to a server?
No. Conversion happens entirely in your browser, so your images never leave your device.
Will the quality improve?
No. Detail already discarded by JPEG compression can't be recovered — but no further quality is lost from this point on.
Why is the PNG so much bigger?
PNG is lossless while JPEG is heavily compressed. A photographic image can grow several times over.
Why convert at all then?
Because JPEG loss accumulates with every re-save. Converting once means repeated edits no longer degrade the image.
Does it add transparency?
The PNG supports an alpha channel, but the photo itself is fully opaque until you cut out a background in an editor.
Can I convert several files at once?
Yes. Add as many JPEGs as you like and download the whole set as a single ZIP.
Is there a file size limit?
No. Because nothing is uploaded, the only limit is your device's memory.
Is there a daily limit?
No. Convert as many images as you want, as often as you want.
Can I resize while converting?
Yes. Set a maximum width and wider images are scaled down with high-quality smoothing.
Does it remove EXIF data?
Yes. Canvas-based conversion drops metadata, including any GPS coordinates in the original photo.
Should I use WebP instead?
WebP offers lossless mode with smaller files than PNG, but fewer desktop applications support it.
Which is better for photos?
JPEG, for storage and web use. PNG is better when you're editing or need transparency.
Does it work with .jpeg files?
Yes. The .jpg and .jpeg extensions are the same format and both are accepted.
Can I download the result as a ZIP?
Yes, when you've converted more than one file.
Does it work offline?
Once the page has loaded it runs entirely in your browser, so it keeps working without a connection.
Does it work on phones?
Yes, in any modern browser on Windows, Mac, Android or iPhone with nothing to install.
Is this converter really free?
Completely free, forever — no account, no ads and no premium wall.
