Sign & Protect PDFs Online — Digital Signatures & Security

Electronically sign contracts, protect documents with 256-bit AES passwords, permanently redact sensitive information, and compare document versions — all free and all processed in your browser. Our electronic signatures are legally valid under the US ESIGN Act, EU eIDAS Regulation, and UK Electronic Communications Act.

Sign PDF Online Free

Draw your signature, type it in a handwriting font, or upload a photo of your handwritten signature — then place it anywhere on your PDF in seconds. Legally valid under the ESIGN Act (US), eIDAS Regulation (EU), and Electronic Communications Act (UK). No account, no download, no watermark.

Protect PDF

Add 256-bit AES password encryption to any PDF with one click — the same standard used by banks and government agencies. Set an open password to restrict viewing, or a permissions password to prevent editing, copying, and printing. Processing happens entirely in your browser.

Unlock PDF

Remove password restrictions from a PDF you own — instantly, in your browser. If you know the document password, enter it once and download a clean, unrestricted copy you can edit, copy, and print freely. No software installation required.

Redact PDF

Permanently black out names, account numbers, email addresses, or any sensitive content before sharing. Unlike simple overlays, our redactions are baked into the PDF at the data level — redacted text cannot be recovered, copied, or searched. GDPR and HIPAA compliant.

Compare PDFs

Upload two versions of a PDF and see every difference highlighted side by side — added text, deleted text, and formatting changes. Perfect for reviewing contract revisions, proofreading document updates, or verifying that only approved changes were made. No account needed.

Organize & Manage PDF Documents

Merge multiple PDFs into one file, split a document into chapters, compress large files for email, rotate scanned pages, delete blank pages, or reorder pages by drag-and-drop. Every organize tool runs locally — a 200-page merge completes in under a second because there is no upload wait.

Merge PDF

Combine two or more PDF files into a single document in any order. Drag, drop, and rearrange pages visually — then download your merged PDF in seconds. No file size limits, no page count restrictions, and no watermarks. A 200-page merge completes in under a second because there is no server upload.

Split PDF

Split a large PDF into smaller files by page range, extract individual pages, or separate a document into equal parts. Enter custom page ranges (e.g., 1–5, 10–15) or let the tool split every N page automatically. Your original file stays unchanged — you download new, smaller PDFs.

Compress PDF

Shrink large PDFs for email, web upload, or cloud storage without visible quality loss. Choose from three compression levels — high quality (minimal reduction), balanced (best for email), or maximum compression (smallest file). Reduce file size by 40–70% while keeping text sharp and images clear.

Rotate PDF

Rotate individual pages or all pages in your PDF by 90°, 180°, or 270° — fix sideways scans, correct landscape pages, or flip upside-down documents. Preview every page as a thumbnail before saving. Fast, free, and processed entirely in your browser.

Delete Pages

Remove unwanted pages from any PDF without affecting the rest of the document. Select pages by number, range, or thumbnail preview — delete blank pages, duplicate pages, or confidential sections in seconds. Your original file is untouched; you download a clean new copy.

Organize Pages

Drag and drop to reorder pages in your PDF visually. See every page as a thumbnail, rearrange them into the sequence you need, and download the reorganized document. Perfect for assembling reports, reordering scanned documents, or preparing presentation handouts.

Crop PDF

Trim margins, remove white borders, or resize the visible area of any PDF page. Set crop dimensions manually or apply the same crop to every page at once. Ideal for preparing documents for print, removing header/footer clutter, or standardizing page sizes across merged files.

Add Page Numbers

Stamp page numbers on every page of your PDF in your chosen position (top, bottom, left, right, centre), font, and size. Start numbering from any number, skip specific pages, or use custom formats like ‘Page 1 of 10’. Applied in seconds — no software needed.

Watermark PDF

Add a text watermark (‘Confidential’, ‘Draft’, your company name) or an image watermark (your logo) across every page of your PDF. Control the opacity, rotation angle, size, and position. Protect intellectual property or mark document status instantly — no account required.

N-up Pages

Print multiple PDF pages on a single sheet — 2-up, 4-up, 6-up, 9-up, or 16-up layouts. Reduce paper consumption, create study handouts, or produce booklet-style printouts. Choose page order (left-to-right or top-to-bottom) and add borders between pages for easier reading.

Interleave Pages

Alternate pages from two separate PDFs into a single merged document — page 1 from PDF A, page 1 from PDF B, page 2 from PDF A, and so on. The perfect solution for combining front and back sides of a duplex scan into one correctly ordered file.

Split by Bookmarks

Automatically split a PDF at each bookmark or chapter heading into separate files. Each bookmark becomes its own named PDF. Ideal for breaking a large manual, textbook, or report into individual chapters for distribution or filing.

Split by File Size

Split a large PDF into smaller chunks, each under a target file size you specify (e.g., 10 MB or 25 MB). The tool intelligently divides pages to stay under the limit. Essential for email attachments, file upload portals, or systems with maximum file size restrictions.

Split by Text

Split a PDF wherever a specific word, phrase, or pattern appears in the document text. Use it to separate a batch of invoices by customer name, break a report at each section title, or extract pages containing specific keywords into individual files.

Deskew PDF

Automatically straighten tilted or skewed scanned pages so text lines run perfectly horizontal. The deskew algorithm detects the angle of misalignment and rotates each page precisely. Essential for OCR accuracy — skewed scans produce significantly more recognition errors.

PDF Overlay

Stamp one PDF on top of another as a background or foreground layer. Use it to apply branded letterheads to plain documents, add watermark PDFs as an overlay, or composite form templates with filled data. Control opacity, position, and which pages receive the overlay.
