常见问题
›How much smaller will my image get?
Photos can shrink 60-80% at quality 75-80 with no visible difference. Logos and graphics with sharp edges have less compressible structure.
›Are my images uploaded?
No — compression happens entirely in your browser. Files never leave your device.
›Lossy or lossless?
Lossy — the most effective. For lossless PNG compression, use a tool like pngcrush or oxipng.
›Is the compressor free?
Yes — fully free, no signup, no file count limits.
