Free PDF Tools: 21 Ways to Merge, Split, Compress and Convert PDFs Online

Most people need a PDF tool a few times a week: combine two contracts, shrink a scan so it fits in an email, turn a PDF into an editable Word file, or add a quick signature. Sign10X includes 21 free PDF tools on every plan, including the Free plan, and using them never counts against your monthly signature envelopes.

Why use Sign10X's free PDF tools?

• Free on every plan. No trial period and no per-file fees.
• Your files stay on your device. The tools run in your browser, so documents are processed locally instead of being uploaded to a server for conversion.
• Ready for signing. Save any result straight into your Sign10X documents and send it for signature.

Organize pages

• Merge PDF — combine several PDFs into one file, in the order you choose.
• Split PDF — break a long PDF into separate files.
• Delete Pages and Extract Pages — remove pages you don't need, or pull out just the ones you do.
• Reorder Pages and Rotate PDF — fix page order and sideways scans.

Convert PDFs

• PDF to Word and Word to PDF — move between editable documents and shareable PDFs.
• PDF to Image and Images to PDF — turn pages into images, or photos and scans into a single PDF.
• PDF to Text — pull the plain text out of a PDF.

Optimize and make scans searchable

• Compress PDF — reduce file size for email and uploads.
• OCR PDF — recognize text in scanned documents so you can search and copy it.
• Flatten PDF — lock form fields and annotations into the page.

Edit, sign and protect

• Add Text & Images — place text, logos or stamps on any page.
• Add Signature — sign a PDF yourself. To collect signatures from other people, send a signature request instead.
• Watermark — mark drafts or confidential copies.
• Protect PDF and Unlock PDF — add a password, or remove one when you know it.
• PDF Metadata — edit the title, author and other document properties.
• Compare PDFs — spot differences between two versions of a document.

Honest about the limits

• PDF to Word keeps text, headings, lists and simple tables, but complex layouts won't match the original exactly.
• Compressing a mostly-text PDF saves little space — the tool tells you when that's the case.
• Unlock PDF requires the correct password; unknown passwords can't be bypassed.
