Questions and answers
Are these PDF tools really free?
Yes. There is no paid plan and no sign-up, and nothing is stamped on your files unless you add a watermark yourself.
Is my PDF uploaded to a server?
No, unless you choose the optional server mode of Compress PDF. The tools run in an isolated frame of your browser that has no network access. You can check this yourself, as shown on Verify it yourself.
Do the PDF tools work on a phone?
Yes, in any current mobile browser. A phone has less memory than a computer, so very large files are easier on a laptop; each tool shows its limits before you start.
Can I edit the text inside a PDF?
Not directly. To change the wording, convert the file with PDF to Word, edit it, and turn it back into a PDF with Word to PDF.
