What converting JPG to PNG does — and doesn't — do

A common misconception is that converting a JPG to PNG will "restore" or "improve" image quality. It can't. JPG is a lossy format: when the image was first saved, fine detail was permanently discarded. PNG is lossless, so it faithfully preserves whatever pixels are in the JPG right now — but it cannot recover what was already thrown away. Your PNG will look exactly like the JPG.

What you do gain is a format that won't degrade further. Every time you re-save a JPG, it loses a little more. A PNG can be opened, edited, and re-saved any number of times with zero additional loss.

When this conversion makes sense

Expect a bigger file

For photos, the PNG will usually be 2–5× larger than the JPG. That's normal — it's the price of lossless storage. If size matters more than losslessness, stay with JPG or try WebP.

How to convert

  1. Output is already set to PNG (the quality slider is disabled because PNG is lossless).
  2. Drop your JPG files onto the zone above, or click to browse.
  3. Download each PNG individually, or download everything as a ZIP.
