WHAT IS JPG TO PNG?

JPG to PNG batch-converts JPG images into lossless PNG format — entirely in your browser.

Features

  1. PNG output is lossless, but cannot restore quality already lost to JPG's original compression.
  2. Batch conversion — one failed file never stops the rest of the batch.

How to use?

  1. Drag or click to upload JPG images (multiple allowed).
  2. Click "Convert to PNG".
  3. Download individually or via ZIP for the whole batch.

Frequently asked questions

Does converting to PNG improve image quality?

No. Any quality loss from JPG's lossy compression cannot be recovered by converting — PNG just losslessly re-saves the pixels as they currently are, and the file is typically larger, not smaller.

Will the resulting PNG have a transparent background?

No — JPG sources have no transparency information to begin with, so the output PNG is fully opaque.

How many JPG files can I convert at once?

Batch upload is supported. One failed file never affects the others, and you can download everything as a ZIP when done.
