Everything You Need to Work with PDF Files — In One Place
PDFs are the most widely used document format in the world — for resumes, invoices, contracts, academic papers, reports, and official forms. But working with PDFs has traditionally required expensive desktop software like Adobe Acrobat. PDF Linx changes that. Every tool you need to convert, edit, compress, organize, and secure PDF files is available here for free, directly in your browser — no installation, no account, no cost.
Whether you need to convert a PDF to an editable Word document, merge multiple PDFs into one file, compress a large PDF before emailing it, or extract text from a scanned PDF using OCR — there's a dedicated tool for every task. All tools are optimized for speed and accuracy, and your files are handled with privacy in mind.

Upload your file, choose the action, download the result. No complicated steps or settings.

Frequently Asked Questions
Do I need to install any software to use these PDF tools?+
No. All PDF Linx tools work entirely online in your browser — just upload your file, process it, and download the result. No desktop software, no app download required.
How do I convert a PDF to Word without losing formatting?+
Upload your PDF to the PDF to Word converter. The tool preserves fonts, tables, images, and overall layout in the DOCX output. For scanned PDFs, run the OCR PDF tool first to extract the text layer before converting.
How do I reduce PDF file size for email or upload?+
Use the Compress PDF tool. Upload your file, select a compression level, and download the smaller version. PDF files can typically be reduced by 50–80% without significant quality loss.
Can I convert Word, Excel, or PowerPoint files to PDF?+
Yes. PDF Linx supports Word to PDF (DOC and DOCX), Excel to PDF (XLS and XLSX), and PPT to PDF (PPT and PPTX). All conversions preserve formatting, tables, and layout.
What is OCR and when do I need it?+
OCR (Optical Character Recognition) converts scanned PDFs — which are image-based — into searchable and editable text. Use the OCR PDF tool when you can't select or copy text in a PDF, which usually means it's a scanned document.
How do I secure a PDF with a password?+
Use the Protect PDF tool to add password encryption. If you already have permission to access a protected PDF and want to remove the password, use the Unlock PDF tool.
How do I rotate pages or sign a PDF online?+
Use Rotate PDF to fix sideways or upside-down pages — rotate by 90°, 180°, or 270°. Use Sign PDF to add a digital signature by drawing, typing, or uploading your signature image.
