Local file validation
This viewer accepts one file whose browser MIME type is application/pdf, up to 50 MB. Files are checked before a preview URL is created. Some operating systems may provide an empty or unusual MIME type; those files are rejected so the viewer does not silently open an unexpected format.
Private browser preview
The PDF is read from your device and rendered by your browser’s built-in PDF support. This page does not upload, index, or store the document. The temporary object URL is revoked when you replace or clear the file and when you leave the page. Browser PDF viewers can still have their own printing, downloading, and permissions controls.
