Frequently asked questions
Is there a file size limit?
No hard limit, but very large images are bound by your device's available memory. Most everyday images compress instantly.
Are my images uploaded anywhere?
No. Compression uses the browser's Canvas API, so files stay on your device.
What format should I export?
Use WebP or JPEG for photos (smaller), and PNG for graphics with sharp edges or transparency.
