JPG to PNG without uploading anything
Drop your JPG files and they come back as PNG, converted by your own browser. Nothing is sent anywhere unless you ask for it.

Or click to choose them. Several at once is fine, and you can drop more later.
Comes out as PNG. You can change this once your images are in.
Output
Everything re-converts as you change it
Around 80 to 90 is where most pictures stop looking different but keep getting smaller.
JPEG cannot be transparent, so whatever was see-through gets this colour.
Aspect ratio is kept, and a picture already smaller than this is left alone.
More than one image comes back as a single .zip.

Metadata is dropped
Redrawing the picture leaves the EXIF block behind, so camera model and GPS coordinates do not come along. The rotation a phone records is applied first, so the result is the right way up.
Your browser sets the limits
Only formats this browser can write are listed, which is why AVIF appears on some machines and not others. Animation is not carried over: a GIF or an animated WebP comes back as its first frame.
Why convert JPG to PNG
PNG is lossless, so every further edit and save keeps exactly what is there. That is what editors, icon tools and some upload forms want.
Worth knowing
Converting does not bring back detail that JPG compression already removed, and the PNG will usually be larger than the JPG was.
Questions people ask
Does converting to PNG improve the quality?
No. It keeps the picture exactly as it is from now on, but the detail the JPG already lost stays lost.
Why is the PNG bigger than the JPG?
PNG stores every pixel without throwing anything away. For a photo that takes much more space than JPG, which discards what the eye barely notices.
Can I get a transparent background this way?
Not by converting alone, since a JPG has no transparency to keep. The background remover cuts the subject out and saves it as a transparent PNG.
Are my images uploaded to convert them?
No. The browser decodes the file, redraws it and encodes it again on your own machine. Nothing is sent unless you sign in and choose to save the result to your account.
Can I convert several images at once?
Yes. Drop as many as you like, and more than one result downloads as a single .zip.
Is the metadata kept?
No. Redrawing the picture leaves the EXIF block behind, so camera model and GPS position do not come along. The rotation a phone records is applied first, so the result is the right way up.
