Free PDF websites differ in ways that matter. Use this checklist.
| Check | Good sign |
|---|---|
| Privacy | States clearly whether files are uploaded and how long they are kept |
| Limits | Clear file size and daily limits |
| Output | No forced watermark on free results |
| Speed | Result in seconds on a normal phone |
| Honesty | Lists tools that actually work |
Try your own sample file on any service first, with a document that is not sensitive.
