Common questions
How does local image compression work?
We draw the image to a canvas element and export it using custom quality levels via browser encoding APIs. The data remains locally in browser RAM.
Will I lose image quality?
Adjustable quality levels let you balance file size savings with visual clarity. Typically, setting quality to 70-80% yields significant byte size savings with minimal visible loss.
