Frequently Asked Questions

Can I mix Word, Excel and PowerPoint in one merged PDF?
Yes. The Merge mode accepts any combination of DOC, DOCX, XLS, XLSX, PPT and PPTX files. Each file is converted to PDF individually, then all PDFs are merged in the order you set by dragging.
How is this different from "Save As PDF" in Microsoft Office?
Office only converts one file at a time and has no merge, watermark or password features. This tool lets you batch convert multiple files at once, merge different file types into one PDF, add diagonal watermark text, and password-protect the output.
What does password protection do?
You can set two passwords: an "Open password" that recipients must enter to view the PDF, and a "Permissions password" that controls whether the PDF can be printed or edited. You can use either or both.
Are my files stored after conversion?
No. All files are processed on our server and automatically deleted within 10 minutes. We never read, share or store the content of your documents.
Is this tool completely free? Is a watermark added to my PDF?
Yes — ToolTiny is 100% free with no sign-up or registration needed. No watermark is added to your converted PDF by default. The watermark feature is optional and only activates if you choose to enable it.
How many files can I convert at once?
You can batch convert up to 20 Office files at once, each up to 20MB. In Merge mode, you can combine up to 20 files of mixed formats (Word, Excel, PowerPoint) into one single PDF.
Can I convert DOCX to PDF without losing formatting?
Yes. ToolTiny preserves fonts, spacing, images, tables, and page layout when converting DOCX files to PDF whenever possible.
Can I batch convert multiple Word, Excel, and PowerPoint files?
Yes. You can bulk convert up to 20 Office files at once, including DOCX, XLSX, PPTX, DOC, XLS, and PPT files.
Does this Office to PDF converter support XLSX and PPTX files?
Yes. ToolTiny supports Microsoft Word, Excel, and PowerPoint formats including DOC, DOCX, XLS, XLSX, PPT, and PPTX files.

You can even add custom text watermarks or encrypt your output PDF with open and permission passwords for ultimate security. For your privacy, all uploaded files are processed via secure HTTPS connections and are automatically deleted from our servers within 10 minutes.

Why Convert Office Documents to PDF?

PDF is the most widely accepted document format for sharing, printing, archiving, and business communication. Unlike Word, Excel, or PowerPoint files, PDFs display consistently across all devices and operating systems.

By converting Office documents to PDF, you can prevent layout shifts, preserve fonts, maintain image quality, and ensure recipients see the document exactly as intended. PDFs are commonly used for contracts, invoices, reports, presentations, proposals, manuals, and academic documents.

Convert Multiple Office Files to PDF at Once

ToolTiny supports batch conversion of Word, Excel, and PowerPoint files, allowing you to convert multiple Office documents into PDF format in a single operation. This saves significant time compared to opening and exporting each file individually.

Whether you need to convert project reports, spreadsheets, training materials, business presentations, or school assignments, our batch Office to PDF converter helps streamline your workflow while preserving document quality.

Secure Online Office to PDF Converter

Security and privacy are important when working with business documents. All uploaded files are transferred using encrypted HTTPS connections and automatically removed after processing.

You can also add password protection to generated PDF files, helping restrict unauthorized access, editing, copying, or printing. This makes ToolTiny suitable for confidential reports, contracts, financial documents, and internal company files.
