Frequently Asked Questions
Is my image uploaded to a server?
No. Compression happens entirely in your browser using the HTML5 Canvas API. Your image is never sent to any server, making this tool completely private.
Why doesn't the quality slider work for PNG?
PNG is a lossless format — quality settings do not apply. The Canvas API produces a valid lossless PNG regardless of the quality value. To get a smaller file from a PNG source, convert it to JPEG or WebP using the format selector.
