What happens when you convert PDF to ICNS
- Every page becomes its own ICNS image (up to 100 pages), downloadable together as a ZIP. Pick 150 dpi for screens or 300 dpi for print.
- Pages are drawn by Mozilla's open-source pdf.js, loaded once (about 2 MB) and run on your device.
- The ICNS file contains every size macOS uses, from 16×16 to 1024×1024 (Retina), stored as PNG.
- For the sharpest icon, start with a square image of at least 1024×1024. Other shapes are centered with transparent padding.

Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many PDF files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting PDF to ICNS reduce quality?
Pages are drawn fresh at the resolution you pick, so text and vector shapes stay sharp. Use 300 dpi for print-quality images.
What about documents with several pages?
Each page becomes its own image, named with its page number, and you can download them all as a ZIP.
How do I use the ICNS file?
In Finder, select an app or folder, press ⌘I, then drag the .icns file onto the small icon at the top of the Info window. In an app bundle, it goes in Contents/Resources.
