Photos are compressed in your browser and never uploaded.
Photos straight off a phone are several megabytes each, which is far more than a web page or an email attachment needs. Compression throws away detail your eye does not notice and can easily cut the file to a fifth of its size.
How to use
- 1 Drop in the images you want to shrink.
- 2 Pick a compression strength — "balanced" is right for most uses.
- 3 Cap the width as well if the images are far larger than they need to be.
- 4 Press compress and check the size reduction before saving.
Frequently asked questions
How much quality do I lose?
At 80% quality the difference is very hard to see on a normal screen, while the file is typically 60–70% smaller. Below 60% you start to see blockiness around edges and in flat areas like skies.
Should I use WebP?
For web pages, yes — it is roughly 25–35% smaller than JPG at the same visual quality, and every current browser supports it. Stick with JPG if the file is going somewhere older or into print workflows.
Can I compress the same file twice?
You can, but do not. Each pass discards detail permanently, and re-compressing an already-compressed image adds visible artefacts for very little extra saving. Always start from the original.
