Frequently Asked Questions

How much can I reduce the file size?
Typically 50-80% reduction at quality 70-80%. The exact savings depend on the image content and original format.
Will my image look blurry after compression?
At quality 70-80%, most images look nearly identical to the original. Below 50%, you may notice some quality loss in detailed areas.
What format is the output?
JPG and WebP inputs are compressed to WebP, which gives the best size-to-quality ratio for photos. PNG files stay as PNG, so transparency is fully preserved. Note the quality slider applies to WebP output; PNG is re-encoded losslessly.
Is there a file size limit?
Images up to 50MB are supported in the browser.
Are my images uploaded to a server?
No, all compression happens in your browser using the Canvas API. Your images never leave your device.
