Image Compressor
Reduce the file size of JPG, PNG and WebP images in your browser. Pick the quality, compare sizes, and download.
How to use the Image Compressor
Drop one or more images, then move the quality slider. Around 70–80% usually keeps a photo looking the same while cutting its size a lot.
PNG files are lossless, so to make a big PNG photo much smaller, save it as JPG or WebP. Your images never leave your device.
Frequently asked questions
Are my images uploaded?
No. Compression runs in your browser; the files never leave your device.
Which format gives the smallest file?
WebP is usually smallest for the same quality, then JPG. PNG is best for screenshots and graphics with flat colours.
How do I get an image under 100 KB or 50 KB?
Lower the quality step by step and watch the new size. If it is still too big, use the Image Resizer to make the picture smaller in pixels first.
