Supported preferences only
This tool writes Hide toolbar, Hide menu bar, Hide window UI, Fit window, Center window, and Display document title. It also supports the standard non-full-screen page mode options Use none, Use outlines, Use thumbs, and Use optional content. Options that pdf-lib does not expose are not offered.
Local processing and file limits
The PDF is loaded and saved locally with pdf-lib. It is never uploaded, indexed, or stored by this page. One application/pdf file up to 50 MB and 200 pages is accepted; encrypted, signed, XFA, malformed, or otherwise unreadable files are rejected.
Reader support varies
Viewer preferences are hints to PDF readers. A browser, desktop reader, or mobile app may ignore some preferences, and writing them does not change page content or enforce a reader interface.
常见问题
你可能还想知道
Does this change the PDF pages?
No. It updates the document catalog preferences and leaves page content untouched.
Will every PDF reader honor these settings?
No. PDF readers may ignore viewer preferences or implement them differently.
Which preferences can I set?
This tool offers only the boolean preferences and non-full-screen page modes exposed by pdf-lib.
Why was my PDF rejected?
Encrypted, signed, XFA, malformed, and unreadable PDFs are not supported. The file must also be application/pdf, no larger than 50 MB, and contain no more than 200 pages.
