Frequently asked questions

Will compression reduce image quality visibly?
At quality settings of 70–85%, compression is nearly indistinguishable from the original for photos. Going below 50% may introduce visible artifacts.
Is my image uploaded to a server?
No. All compression happens entirely in your browser using the canvas API. Your image is never sent anywhere.
What formats are supported?
JPEG, PNG, and WEBP. JPEG and WEBP support quality-based lossy compression; PNG is re-encoded through the same pipeline.
