Frequently Asked Questions
Is WebP better than JPG for HEIC photos?
For web use, usually yes. WebP typically produces files 25–35% smaller than JPG at the same visual quality, and it supports transparency. Modern browsers all support WebP natively.
Will my iPhone photos be uploaded to a server?
Never. HEIC decoding and WebP encoding both happen locally in your browser using WebAssembly. Your photos stay on your device at all times.
Can I convert multiple images at once?
Yes — use Image Factory to build a batch pipeline: convert, compress, crop and resize many images in one flow, entirely on your device.
