Image Compressor

Shrink image file sizes and resize photos in your browser. Convert to JPEG, WebP or PNG, adjust quality, and compare before and after — images are never uploaded.

Frequently asked questions

Are my images uploaded?

No. Compression uses your browser's canvas, so photos never leave your device — safe for personal documents.

Which format gives the smallest file?

WebP is usually 25–35% smaller than JPEG at similar quality. Use PNG only for graphics that need transparency or sharp edges.

How do I get under a size limit like 100 KB?

Lower the quality slider and reduce the maximum width until the 'after' size is below the limit — the new size updates instantly.
