What is a PNG en JPG?
JPG's lossy compression produces much smaller files than PNG for photographic images, which matters when a screenshot or photo saved as PNG is too large to attach to an email or upload to a form with a strict size limit.
How to use the PNG en JPG
- Add one or more PNG images
- Each one is converted to JPG, on your device
- Download the JPG (or a ZIP for multiple images)
Example
A 5MB PNG screenshot with lots of photographic detail often converts to a 500KB-1MB JPG at typical quality settings — a 5-10x reduction, since JPG discards imperceptible detail that PNG preserves exactly.

Frequently asked questions
Is my image uploaded anywhere?
No — PNG en JPG runs entirely in your browser using JavaScript/WebAssembly. Your image is never sent to a server.
Is there a file size limit?
Free use covers files up to 100MB per file; signing up for Pro raises that to 500MB.
What happens to a PNG's transparent areas when converting to JPG?
JPG doesn't support transparency, so transparent areas are filled with a solid white background in the converted file — flatten or replace that background first if you need a different fill color.
Does converting to JPG lose image quality, even at high settings?
Yes, slightly — JPG compression is lossy by design, so some fine detail is discarded even at high quality settings, though it's usually imperceptible on photographic images at typical quality levels.
