About Compress Image
This tool re-encodes your images with a quality setting you control. JPG and WebP use lossy compression; PNG is optimised without changing how it looks. The saving depends on the picture, so a before-and-after size is shown for each file.
- Files stay on your device – nothing is uploaded
- Free, with no sign-up and no watermark
- Works on several images at once where the tool allows it
Frequently asked questions
Is my image uploaded anywhere?
No. Compression runs inside your browser, so the file never leaves your device.
Which quality should I choose?
For photos, 75–85% usually looks the same as the original while saving a lot of space. Lower it only if you need a smaller file.
Can I compress many images at once?
Yes. Add up to 50 images and download them together as a ZIP.
