FAQ

Are my images uploaded to a server?
No. All image processing happens entirely in your browser using the Canvas API and FileReader. Your images never leave your device.
What image formats are supported?
PNG, JPEG, WebP, SVG, GIF, BMP, ICO, AVIF, and TIFF. Not all browsers support all formats — WebP and AVIF require modern browsers.
Is there a file size limit?
There is no hard limit, but very large images (50MB+) may be slow to process since everything runs in your browser. For best performance, keep images under 20MB.
