Frequently Asked Questions

Does compression affect image quality?

Lossy compression (used for JPGs) reduces some quality in exchange for smaller files. Lossless compression (used for PNGs) reduces file size with no quality loss.

Is my image uploaded to a server?

No — compression happens entirely in your browser. Your images are never sent to or stored on any server.

What file formats are supported?

JPEG, PNG, and WebP are supported for compression.

How much can I compress an image?

Results vary by image, but typical reductions range from 40–80% with minimal visible quality loss.
