PDF Toolbox
Effective 20 October 2026
By using PDF Toolbox, you agree to these terms.
PDF Toolbox lets you merge, split, sign, organize, compress, rotate, protect, unlock and create PDF files from images and scans, on your own device. The app works on copies of the files you choose and does not change the original unless you replace it yourself.
PDF Toolbox has no sign-up or account system. Your files stay on your device. Results are kept in the app until you clear them or uninstall it; we have no copy and cannot recover them.
Every tool is free to try for 30 days. After the trial, the tools continue to run and you can preview the results, but saving and sharing the finished file requires a one-time purchase made through Google Play. It is not a subscription and does not renew. Purchases are handled entirely by Google under its own terms, and refund requests follow Google Play's refund policy. Use "Restore purchase" in Settings to re-link an existing purchase after reinstalling or changing phones.
Only use PDF Toolbox on files you have the right to use. You are responsible for keeping backups of important documents. If you protect a PDF with a password, we cannot recover that password for you, and a lost password may make the file impossible to open. Digital signatures added with the Sign tool are an image of your signature placed on the page; they are not a certified or legally verified digital signature, and whether one is acceptable for a particular purpose is for you to determine.
Don't use the app to remove protection from files you are not authorised to open, to infringe others' rights, or to attempt to reverse-engineer, tamper with or circumvent the app's trial or purchase mechanisms.
PDF Toolbox is provided "as is". We work to keep it reliable, but results such as compressed file size depend on the document, and we are not liable for data loss, damaged or unreadable files, lost passwords, or decisions made using documents you edit with the app. Keep a copy of important originals.
If these terms change materially, we will update the effective date above and, where required, notify you in the app.
