JPG to PNG

Convert JPG photos to PNG — a lossless format that survives repeated editing without degrading.

Files never leave your device

How to use JPG to PNG

  1. 1Add one or more JPG files.
  2. 2Press Convert.
  3. 3Download the PNG files individually or as a ZIP.

How it works

The JPEG is decoded to raw pixels and re-encoded as PNG, which stores those pixels losslessly. Nothing more is lost in the conversion — but nothing that JPEG already discarded comes back either. Compression artefacts baked into the original stay in the PNG.

The practical reason to convert is editing. Every time a JPEG is saved it is re-compressed, so repeated edits accumulate damage. PNG can be opened and saved indefinitely with no further loss, which makes it the better working format.

Expect the PNG to be substantially larger — often three to five times the JPEG — because lossless storage of photographic detail simply takes more space.

Images are decoded by the browser, redrawn on a canvas and re-encoded on your own machine. Nothing is uploaded, so there is no waiting on a queue and no copy of your photos anywhere else.

Frequently asked questions

Why is my PNG so much bigger than the JPG?
PNG stores every pixel exactly, while JPEG throws away detail to save space. For photographs, that difference is usually three to five times the file size.
Does converting improve the quality?
No. Conversion preserves what is there; it cannot restore detail JPEG already discarded. It does prevent further loss from future edits.
Will the PNG have transparency?
No. JPEG cannot store transparency, so there is none to carry over. The PNG will be fully opaque.
