Frequently asked questions
Is this image compressor really free?
Yes — compressing images is free, with no watermarks and no signup. There is no daily cap on how many images you can optimize.
Will my transparent PNG stay transparent?
Always. Transparency is detected before compression and carried through every step — we will never flatten an alpha channel onto a background colour. If a setting cannot preserve transparency, we keep the format that can instead of silently dropping it.
How much smaller will my image get?
Photos usually drop 60–80% on the balanced setting with no visible difference. Screenshots and flat graphics saved as PNG often drop further, because we palette-optimize them rather than just re-deflating the same pixels.
Does compressing change my image dimensions?
No. Width and height stay exactly as they were — we reduce the bytes needed to store the same pixels. Your image is never upscaled or cropped.
What happens to my files?
Files are uploaded over an encrypted connection, processed on our servers, and permanently deleted within 24 hours. Nobody looks at them and they are never shared.
