PDF Coast vs online PDF tools
Smallpdf, iLovePDF and similar sites are quick for a one-off job on any device. A desktop app is better when the file is private, big, or one of many.
Checked and updated 25 October 2026
The short answer
Use an online PDF site for an occasional, non-sensitive file on a phone, a Mac or someone else's computer. Use PDF Coast for private documents and regular work on your own Windows PC: files are opened on your computer and never uploaded, it works without internet, and the free tools have no daily limits or watermarks. Editing text, OCR and export to Word are part of PDF Coast Pro, a one-time purchase.

Questions
Do online PDF sites keep my files?
Reputable sites say they delete uploaded files after a short period, often an hour or two. The file still travels to and sits on someone else's server for that time. With PDF Coast it is opened on your PC and never sent anywhere.
Is PDF Coast as easy as a website?
After a one-minute install, yes: open a PDF, pick a task such as Merge or Compress, and save. Your files stay in your own folders, so there is no download step afterwards.
Can I use PDF Coast on my phone?
No. PDF Coast is a Windows 10 and 11 app. On a phone, an online site or the phone's own PDF viewer is the better choice.
