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 traditional desktop PDF software.

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.

What is QuickGantt Excel template?

QuickGantt is our Excel Gantt chart template with automated dependency tracking. The free version includes up to 35 tasks and 180 project days. Pro version ($18) offers unlimited tasks and up to 2000 project days. Works with Excel 2019, 365, and newer versions.

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

Yes, our time zone converter supports all major time zones including EST to IST, PST to IST, CST to IST, and UTC conversions. Compare multiple time zones simultaneously with our visual timeline and meeting scheduler — perfect for international teams.

Is there a discount available?
