How to convert JPG to PNG

  1. Choose one or more JPG files or drag them into the box above.
  2. FormatOtter converts it to PNG instantly in your browser.
  3. Download files individually or download the whole batch as a ZIP.

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.

Batch input can mix PNG, JPG/JPEG, and WebP files. Every selected image is converted to PNG.

Is this private?

Yes. FormatOtter runs entirely in your browser using the built-in canvas API. Your image is never sent to a server or seen by anyone. To preserve an unfinished queue across refreshes, your browser may keep a local copy on this device until processing succeeds or you clear the queue. 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.
