How to convert JPG to PNG

  1. Drop the JPG files in. One or many. Photos from a phone or camera, or images pulled from a page.
  2. Download the PNGs. There are no quality settings, because PNG has no quality loss. Each file is converted as it is.
  3. Edit freely. Every save of a PNG is exact, so the image stops degrading the way a JPG does when it is edited and saved again and again.

Why people convert JPG to PNG

A form that wants PNG
Some upload forms, app stores and print services accept PNG only. Converting takes seconds and the image is unchanged.
Editing without further loss
Cropping, annotating and re-saving a JPG adds a little damage each time. Convert to PNG first and the edits stay clean.
Making a transparent version
PNG supports transparency and JPG does not. Converting is the first step before removing a background in an editor.

What conversion does not do

  • It does not restore detail the JPG already lost. The PNG is an exact copy of the JPG as it is now, including any softness or blocks. From here on, nothing more is lost.
  • The PNG will be larger, often three to eight times, because PNG stores every pixel exactly. That is the trade for lossless.
  • It does not add transparency by itself. It gives you a file that can hold transparency once you remove the background in an editor.

Questions people ask

Does JPG to PNG improve quality?

No. It stops further loss, but it cannot recover detail the JPG already discarded. The PNG is an exact copy of the JPG at this moment.

Why is the PNG so much bigger?

PNG stores every pixel exactly, while JPG throws detail away to shrink. Three to eight times larger is normal for photos. If size matters more than exactness, keep the JPG or use WebP.

Will the PNG have a transparent background?

Not by itself. A JPG has no transparency to carry over. Convert to PNG, then remove the background in an editor; the PNG can hold the result.

Can I convert many JPGs at once?

Yes. Drop them all; each is converted and one button downloads everything.

Is JPEG the same as JPG?

Yes. Same format, two spellings of the extension.
