Frequently asked questions
Which files do I get?
favicon.ico (16, 32 and 48 px by default; you can pick the sizes), PNG icons from 16 to 512 px, apple-touch-icon.png (180 px), Android Chrome icons, a site.webmanifest and an HTML snippet to paste into your <head>.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
