How to convert JPG to PNG

  1. Choose a JPG file or drag it into the box above.
  2. FormatOtter converts it to PNG instantly in your browser.
  3. Download the PNG.

Some tools and workflows require PNG input, and PNG avoids any further quality loss when an image will be edited repeatedly. This converter produces a lossless PNG from your JPG, locally in your browser.

Supported formats

Input: JPG/JPEG images (.jpg, .jpeg). Output: PNG. The PNG is a lossless copy of the decoded JPG.

Is this private?

Yes. FormatOtter runs entirely in your browser using the built-in canvas API. Your image is never sent to a server, never stored, and never seen by anyone — it stays on your device the whole time. You can even load this page and then disconnect from the internet; the tool keeps working.

Frequently asked questions

Does converting JPG to PNG improve quality?

No. Compression artifacts already present in the JPG remain — PNG just prevents any further loss from future saves and edits.

Why is the PNG so much bigger than the JPG?

PNG stores the image losslessly, which takes far more space for photographic content. That's the trade-off for a format that never degrades.
