Frequently asked questions
Is the image compressor free?
Yes, completely free with no sign-up and no watermarks.
Will compression reduce the quality of my image?
It depends on the quality setting you choose. At 80% most photos look identical to the original while being much smaller. Move the slider to find the balance you like.
Is there a maximum file size?
The only limit is your browser's memory. Very large photos (50 MB and above) may be slow on older devices.
Are my images uploaded anywhere?
No. Compression runs entirely in your browser — your images never leave your device.
