Image Compressor
Shrink JPG, PNG, or WebP files without visible quality loss. Ideal for websites, email, and social - everything runs locally.
Big product photos and camera exports slow down websites and blow past email attachment limits. This tool re-encodes JPG, PNG, or WebP images through the browser's Canvas API at a quality level you control, typically cutting file size 60-90% with minimal visible difference at normal viewing sizes. It's the fastest fix when you just need a smaller file and don't need to change dimensions or format - pair it with the Image Resizer first if the image is also physically larger than you need.

Common questions
How does it compress?
Re-encodes via Canvas + your chosen quality. JPEG and WebP typically cut size 60–90%.
Which format compresses smallest?
WebP usually produces the smallest file at a given visual quality, followed by JPEG. PNG stays lossless so it compresses less aggressively.
Will this resize my image too?
No - dimensions stay the same. Use the Image Resizer first if you also need smaller pixel dimensions.
Does it upload my photos?
No. Compression runs entirely in your browser on a canvas - nothing is sent to a server.
