What is PDF Hub?
PDF Hub is a free online workspace for working with PDF files. It brings 30+ everyday PDF tools under one roof — from merging and splitting to compression, conversion between formats, signing, OCR and AI-powered summarisation. Nothing to install, no account required for the core utilities, and no vendor lock-in. Every action runs in your browser on top of open, well-known engines (pypdf, PyMuPDF, LibreOffice, Ghostscript, Tesseract).
The site is built around one principle: you shouldn't have to jump between five different websites to prepare a single document. Whether you are combining scanned invoices for accounting, compressing a résumé to fit an email attachment cap, translating a product manual, or sending a contract for e-signature, the workflow lives in the same tab, with the same interface, in the language you prefer.
All uploads travel over HTTPS. Regular tools use temporary storage that is wiped as soon as the request finishes; AI tools (Summarizer, Translate) send only the extracted text to a large-language-model provider through the Emergent LLM proxy. Full transparency and retention limits are in the Privacy Policy.
Why choose PDF Hub
Fast, browser-based
Every tool runs on our servers over HTTPS — no plugin, no install, no waiting for a heavy desktop app to start. Most operations finish in a few seconds.
Files auto-deleted
Your uploaded PDFs are held in a temporary folder that is deleted as soon as the request finishes. Nothing is added to a database.
Works in four languages
The interface is available in English, Hindi, Spanish and French. Language preference is remembered on your device.
30 tools, one place
Merge to sign, compress to translate — every common PDF task is covered without hopping between websites.
Explore the 30 tools by category
Six focused categories cover the most common jobs a PDF file goes through, from raw scan to signed archive. Click a category to open the matching tools grid, or use the search box in the top-right to jump straight to a tool.
Organize PDF
Rearrange, split, or clean up PDF pages. Six tools: Merge, Split, Rotate, Organize (drag-drop), Page Numbers, Scan to PDF.
Optimize PDF
Reduce file size, repair damaged files, and archive as PDF/A. Three tools: Compress, Repair, PDF to PDF/A.
Convert PDF
Convert PDFs to Word, PowerPoint, Excel, JPG, Markdown, HTML — and back. Ten tools covering every common format.
Edit PDF
Add text, place a signature, watermark, compare two files, or redact sensitive content. Six visual editors.

Password-protect, unlock, or fill interactive forms. Three tools that respect strong AES encryption.
PDF Intelligence (AI)

Frequently asked questions
Is PDF Hub really free?▾
Yes. Every tool in the grid above is free to use without an account. Free accounts add saved history, workflow saving and per-user credits for the AI tools (Summarizer, Translate). There is no paid plan required for any of the 30 utilities.
Are my uploaded PDFs kept on your servers?▾
No. Regular tools (merge, split, compress, convert, rotate, sign, protect, etc.) write your file to a temporary folder that is deleted the moment processing finishes — usually within seconds. Nothing is written to our database. AI tools (Summarizer, Translate) extract the text and send only that text to a large-language-model provider via the Emergent LLM proxy; the raw PDF is not stored either. Full details are in the Privacy Policy.
Do PDF Hub tools work on mobile phones?▾
Yes. The whole site is a responsive web app — every tool works on iOS Safari 14+ and Chrome for Android. There's nothing to install. The dropzone accepts multi-file selection from the phone's file picker or camera roll, and downloads land in the standard Downloads / Files location on your device.
Which PDF conversion tools are supported?▾
PDF ↔ Word (DOCX), PDF ↔ PowerPoint (PPTX), PDF ↔ Excel (XLSX), PDF ↔ JPG / PNG, PDF ↔ Markdown, and HTML → PDF. Each conversion uses the appropriate open-source engine (pdf2docx, LibreOffice, PyMuPDF, WeasyPrint) — see the individual tool pages for what to expect.
Can I sign a PDF electronically with PDF Hub?▾
Yes. The Sign PDF tool supports signing yourself (drop a signature onto the page) and sending for signature (email a signing link to another party, DocuSign-style, with an audit trail: sent → viewed → signed timestamps). Electronic signatures are legally recognised in many jurisdictions; for high-stakes documents, check the requirements of the specific country and document type.
How large a PDF can I upload?▾
The interface accepts individual files up to about 100 MB — the practical cap set by browsers on a single upload. Larger files should be compressed first with the Compress PDF tool, or split into parts with Split PDF, then processed in batches.
How-to guides for common PDF problems
Short, practical walkthroughs for the tasks people search for most: reducing a PDF under 1 MB, converting a scanned document into editable Word, splitting a book into chapters, adding a strong password to a contract, and running OCR on a phone-photographed document.
