Beperkingen
ICNS Beperkingen
- macOS-only — Windows and Linux do not use ICNS.
- Few third-party editors create ICNS directly; most designers export PNGs and run iconutil.
- No compression beyond per-size PNG/JPEG2000 encoding.
- Format is effectively frozen — Apple has not expanded it in years.
PDF Beperkingen
- Editing is difficult — the format is optimized for display, not mutation.
- Text extraction can scramble reading order in multi-column layouts.
- File sizes balloon quickly when embedding high-resolution images or fonts.
- Accessibility (screen readers) requires careful tagging that many PDFs skip.
- JavaScript support has historically been a malware vector.
