Frequently Asked Questions

Are these image compressors free?

Yes — every compressor listed is free to use with no limit on the number of images you process.

Will compression reduce my image quality?

Most tools offer adjustable quality. At 70–80% quality, images look nearly identical while shrinking 50–80% in file size.

Are my images uploaded anywhere?

No. Compression runs locally in your browser using Canvas and WebAssembly — your images never leave your device.
