Use an online tool when upload is acceptable
An online tool can be fine for quick, low-risk one-off documents where the upload terms and limits fit your needs.
Check the installer first
Use Microsoft Store when possible, compare the Downloads card, then review the linked VirusTotal report before running standalone files.
Online can still fit public one-offs
For public, non-sensitive, one-time PDF changes, a browser tool may be faster if upload terms and file-size limits fit.
