Frequently Asked Questions

Everything you need to know about our free Excel and PDF tools.

How do I remove password protection from Excel files?

Use our Excel password remover tool that works entirely in your browser. Upload up to 10 Excel files (.xlsx or .xlsm), and our tool will remove password protection from workbooks and worksheets without uploading your data to our servers. Completely free with no limitations.

How do I unlock a PDF to print or edit it?

Drop your PDF into our PDF Unlocker. It uses pdf-lib to re-save the file, which strips Owner Password restrictions — enabling printing, editing, and copying. Important limitation: if the PDF requires a password just to open it (User Password / AES encryption), the content itself is encrypted and cannot be unlocked in the browser. In that case you will need a desktop tool such as Adobe Acrobat.

Are these tools really free and private?

Yes — both the Excel Unlocker and PDF Unlocker are completely free. Files are processed locally in your browser and never uploaded to our servers. No account or signup required.

We also offer a range of premium, automated Excel templates (Gantt charts, desk booking, and more) that go beyond what free tools can do. These are paid products, but we stand behind every one of them — our templates have hundreds of satisfied users, and every purchase comes with a full money-back guarantee if you're not happy.

Can I convert EST to IST and other time zones for free?
