Free PDF Tools for Teachers — Merge, Split, Compress & Convert

Merge, split, compress, convert and organize your PDFs — almost every tool below runs right in your browser, so your files never leave your device. (AI Summarizer and Translate PDF are the exceptions — they send extracted text to our AI service.)

All 35 tools are live

Merge, Split, Extract, Remove, Rearrange, Rotate, Images to PDF, PDF to Images, PDF to Word, PDF OCR, Compress, Add Watermark, Add Page Numbers, Sign, Protect, Unlock, Scan to PDF, Repair, Crop, Edit, Forms, Redact, Compare, PDF to Markdown, PDF to Text, Word to PDF, Excel to PDF, PowerPoint to PDF, PDF to Excel, PDF to PowerPoint and PDF to PDF/A all run right in your browser — files never touch a server (OCR briefly fetches the open-source Tesseract engine; Protect/Unlock, Word/Excel/PowerPoint conversions and PDF to Excel each fetch a small open-source library the first time they're used; the files themselves still never leave your device). Also check out PDF → Test Paper. AI Summarizer and Translate PDF are the two exceptions — they send the PDF's extracted text to MulVidyaAi's AI service to generate the summary or translation.

Frequently Asked Questions

Are these PDF tools really free?

Yes. All 35 tools — merge, split, compress, convert, watermark, and the rest — are free to use, with no signup required.

Is my PDF uploaded to a server?

No, for almost every tool your file is processed entirely on your own device using open-source libraries and never leaves your browser. The two exceptions are AI Summarizer and Translate PDF, which send the PDF's extracted text (not the file itself) to MulVidya AI's service to generate the summary or translation.

Can I merge or split multiple PDFs at once?

Yes — Merge PDF combines any number of files into one, and Split PDF, Extract Pages, and Remove Pages let you pull out or drop specific pages in a few clicks.

Do you have a PDF compressor?

Yes. Compress PDF shrinks large files for easier sharing and emailing, right in your browser.

Can teachers use these tools for classroom materials?

Yes — teachers commonly use Merge, Watermark, and Add Page Numbers to prepare worksheets and test papers, and PDF → Test Paper to turn a chapter PDF straight into a printable question paper.

Do I need to install any software?

No. Every tool runs in your web browser on desktop or mobile — nothing to install.
