Frequently Asked Questions
Does compression happen on the server?+
No — everything runs in your browser using the Canvas API. Your image is never uploaded to any server.
Which format gives the smallest file size?+
WebP typically gives 25–35% smaller files than JPEG at the same quality. PNG is lossless and best for graphics/screenshots.
Will I lose image quality?+
JPEG and WebP use lossy compression — quality above 70% is usually indistinguishable from the original. PNG is lossless so quality is never affected.
What is the maximum file size?+
Since processing happens in your browser, the limit depends on your device memory. Most images up to 50MB work fine.
