A complete resource for working with PDFs online — from basic edits to advanced features. All tools run in your browser with zero server uploads.
Updated June 27, 2026
PDF (Portable Document Format) was created by Adobe in 1993 to present documents consistently across any device or platform. Unlike Word documents or web pages, a PDF preserves fonts, images, layouts, and formatting exactly as intended.
Today, PDF is the universal format for sharing documents professionally — used for contracts, invoices, eBooks, forms, reports, and archival records. Billions of PDFs are created, edited, and shared every day.
The challenge? Most PDF editors are expensive (Adobe Acrobat), require server uploads (SmallPDF, iLovePDF), or limit free usage. PDFTools solves this by offering free, private PDF editing entirely in your browser.
Basic PDF editing includes tasks like rotating pages, deleting pages, rearranging pages, and adding text. Here are the tools you need:
Fix pages that were scanned upside-down or rotated. Rotate individual pages or entire documents.
Drag and drop to reorder pages, delete unwanted pages, and arrange your document structure.
Remove specific pages from your PDF. Useful for stripping cover pages, blank pages, or appendices.
Add text boxes, rectangles, circles, and lines to your PDF pages. Perfect for filling forms or highlighting sections.
Large PDFs are slow to email, upload, and download. Compression reduces file size by optimizing images, removing redundant data, and streamlining the PDF structure.
Our PDF Compressor uses pdf-lib to compress PDFs client-side. You can choose from multiple compression levels:
Pro tip: Compress PDFs before uploading to cloud storage or sending via email — a 20MB PDF can often be reduced to 3-5MB without noticeable quality loss.
Combining multiple PDFs into one document or extracting pages from a large PDF are two of the most common PDF tasks.
Combine multiple PDF files into a single document. Drag and drop to reorder files before merging. Useful for consolidating reports, contracts, or scanned documents.
Extract specific pages or divide a large PDF into smaller files. Split by page range, extract every N pages, or separate single pages.
Advanced splitting: extract chapters and sections from a PDF using its bookmark/outline structure. Perfect for eBooks and manuals.
Add blank pages between existing pages — useful for creating separators, interleaving, or formatting booklets.
Converting between PDF and other formats is essential for document workflows. PDFTools offers multiple conversion options:
Convert JPG, PNG, WebP images to PDF. Combines multiple images into one PDF document.
Convert each PDF page to a JPG or PNG image. Useful for sharing individual pages or inserting into presentations.
Convert HTML content or web pages to PDF. Enter HTML code and download a formatted PDF.
Convert plain text to a formatted PDF document. Fast way to create PDFs from notes or code.
Extract text from PDFs and convert to editable DOCX format for Microsoft Word.

Protecting sensitive information in PDFs is critical for business and personal documents.
Add password protection to your PDF. Prevent unauthorized opening, printing, or editing of sensitive documents.
Remove password protection from PDFs you own. Extract content from protected documents you have permission to edit.
Permanently remove sensitive information from PDFs. Black out text, images, or sections before sharing.
Automatically find and redact specific words or phrases across your entire document. Ideal for GDPR compliance.
Strip hidden metadata from PDFs — author names, creation dates, software used, and embedded files.
Mark up documents, add comments, and sign PDFs electronically without printing.
Add highlights, underlines, strikethroughs, and comments to PDFs. Perfect for reviewing documents.
Add your signature and initials to PDF documents. Draw, type, or upload an image of your signature.
Complete fillable PDF forms online. Type into form fields, check boxes, and submit digitally.
Add text or image watermarks to your PDF. Mark documents as Draft, Confidential, or with your brand logo.
Premium tools for power users who need more from their PDF editor:

Side-by-side PDF comparison with highlighted differences. Essential for contract reviews and version tracking.
Bulk generate personalized PDF certificates from a template and CSV data. Perfect for course completions.
Add sequential page numbers to every page. Essential for legal documents, discovery, and indexing.
Convert PDFs to booklet format (side-by-side, 2x2 grid, 4x4 grid) for printing and binding.
Rename PDF files by metadata (title, author, page count) with customizable naming patterns.
Transform PDF colors — dark mode, grayscale, or high contrast. Reduce eye strain when reading PDFs at night.
Add QR codes to every PDF page. Perfect for document tracking, linking to digital resources, or branding.
Modern PDF editing goes beyond simple file operations. PDFTools offers AI features that transform how you work with documents:
Upload any PDF and ask questions about its content using AI. Get summaries, extract key data, find specific information, and generate insights from your documents — without reading them entirely. Supports long documents with intelligent context management.
Extract text from scanned PDFs and images using Tesseract.js OCR. Make scanned documents searchable, selectable, and editable. Supports multiple languages.
Coming soon: AI document summarization, AI form auto-fill, and intelligent data extraction will make PDFTools even more powerful.
A compressed PDF uploads faster, emails quicker, and uses less storage. Run compress as the last step before sharing any PDF.
Before sharing PDFs externally, use the metadata sanitizer to remove author names, creation dates, software info, and hidden content.
For documents that need to be preserved long-term (legal records, historical archives), convert to PDF/A format which ensures future readability.
PDFTools runs entirely in your browser. Once loaded, you can disconnect from the internet and still process PDFs. Your files never leave your device.
No uploads, no signup, no limits. 100% free PDF editing in your browser.
