Frequently Asked Questions
Which favicon sizes are generated?
16, 32, 48, 180, 192, and 512 pixels — covering browser tabs, Apple touch icons, and PWA manifest icons.
What image formats can I upload?
PNG, JPEG, and WebP. The tool scales your image to each square size and exports PNG files in a ZIP.
Should my source image be square?
Square sources look best. Non-square images are stretched to each square size — crop to square first for accurate proportions.
Are there file size limits?
Processing runs in your browser, so very large files may be slow or fail on low-memory devices. For best results, keep images under about 20 MB and PDFs under about 50–100 MB.
Is this tool free?
Yes. This tool is completely free to use with no sign-up, no limits, and no hidden fees.
Does my data leave my browser?
No. All processing happens entirely in your browser using client-side JavaScript. Your data is never sent to a server or stored anywhere.
Does this tool work on mobile?
Yes. PeasyDo tools work in modern mobile browsers on iOS and Android. For file tools, use a browser that supports file uploads and downloads.
Do I need to install software?
No. Everything runs in your browser — no desktop app, plugin, or account required.
