Compress Image

Reduce the file size of JPG, PNG, and WebP images with a quality slider and live size preview. Compression runs locally so your images stay private.

Runs entirely in your browser — nothing is uploaded

Frequently asked questions

How much smaller can my image get?+

Photos typically shrink 60–90% with little visible quality loss. Drag the quality slider and watch the live file-size readout to find your sweet spot.

Will compressing lose quality?+

JPG and WebP use lossy compression, so very low settings can soften detail. At 70–85% quality the difference is usually invisible. PNG stays lossless.

Is it really private?+

Yes — compression runs in your browser with the Canvas API. Your image is never uploaded, and metadata is stripped in the process.
