Good to know
JPG and WEBP are compressed by finding the best quality that meets your goal. PNGs with transparency stay PNG, with an optimised colour palette; other PNGs are saved as JPG or as a palette PNG, whichever is smaller.
If an image can’t get smaller at your settings, the original is kept so you never get a bigger file.
Private by design. Compress Image works inside your browser. Your file is processed on your device and is not uploaded to our server.
Limits to know before you start
- Very small targets lower quality and, if needed, the pixel size.
- PNG photos shrink most as JPG. PNGs with transparent areas stay PNG so the transparency is kept, which saves less.
- If an image cannot get smaller at your settings, the original is kept.
If something goes wrong
A picture will not open. The file may be damaged or in a format your browser cannot read. Convert it to JPG with Convert Image, or take a screenshot of it, and try again.
The image did not get smaller. It was already well compressed. Try a lower quality or a target size, or convert PNG to JPG.
Compress Image – questions
How do I compress an image to 50 KB?
Choose “Target size”, type 50 and press Compress images.
Will the photo look worse?
At the recommended quality the difference is hard to see. Very small targets reduce quality and, if needed, dimensions.
Can I compress many photos at once?
Yes. Add as many as you like; they download as a ZIP.
