What image formats can I upload?
You can upload PNG, JPG/JPEG, and SVG files. For best results, use a square image at least 512x512 pixels. Non-square images are automatically center-cropped.
What sizes are generated?
Eight standard sizes: 16x16, 32x32, 48x48, 64x64, 128x128, 180x180 (Apple Touch Icon), 192x192 (Android Chrome), and 512x512 (PWA splash screen).
Is my image uploaded to a server?
No. All processing happens entirely in your browser using the Canvas API. Your image never leaves your device. Nothing is sent to any server.
Can I create a favicon from an emoji?
Yes. Switch to the Text/Emoji tab, type an emoji, choose background and text colors, adjust the font size, and generate. Emojis render using your system's emoji font.
