PDF Tools

Compress, merge, split, convert, and edit PDF files in your browser

PDF is the format people reach for when a document needs to look the same on every screen and every printer. Whether you are a student combining lecture notes, a freelancer sending an invoice, or a business archiving contracts, the workflow is usually the same: pull a few files together, trim what you do not need, shrink the result, and send it on its way. Favtoo bundles every step of that pipeline into a single browser tab.

Each PDF tool below runs locally with the open-source pdf-lib and Mozilla's PDF.js engines, which means your document never leaves your device. There is no upload bar, no temporary server file, and no account required. You can compress, split, merge, rotate, watermark, redact, and convert PDFs to and from common image and Office formats — all offline-capable once the page has loaded. If you need to chain several actions together, the Workflows feature lets you save a multi-step recipe (for example, "compress then watermark then merge") and rerun it on new files in one click.

If a result is not what you expected, you can re-run any tool as many times as you like. We do not throttle individual usage beyond a soft limit designed to discourage automated abuse. By using these tools you agree to our terms; if you would prefer a different privacy or processing model, you should not use the website.

PDF to Text Extractor

Extract all text content from a PDF and download it as a plain text file. Preserves reading order across all pages.

Excel to PDF

Convert Excel spreadsheets (.xlsx) to a paginated PDF. Each worksheet is rendered as a clean, printable table with auto-fit columns and repeated headers.

HTML to PDF

Convert an HTML file to a styled PDF. Headings, paragraphs, lists, links, and inline emphasis are preserved with semantic typography.

RTF to PDF

Convert Rich Text Format (.rtf) documents to a clean paginated PDF. Bold, italic, paragraphs, and headings are preserved.

DOCX to PDF

Convert a Microsoft Word .docx document to a clean PDF in your browser. The mammoth.js parser extracts the document content and our existing HTML-to-PDF pipeline renders it.

Editing

PDF to Black & White

Convert a color PDF to grayscale. Each page is rendered, desaturated, and re-embedded in a new PDF.

Split Pages Horizontally

Split each PDF page into left and right halves. Ideal for scanned book spreads where two pages are captured in one scan.

PDF Comparison Tool

Visually compare two PDF files. Each page is rendered and diffed pixel-by-pixel, highlighting all changes in red.

Interleave PDF Pages

Interleave pages from two PDFs by alternating pages (A1, B1, A2, B2…). Ideal for reassembling duplex scans.

Reverse PDF Pages

Reverse the page order of a PDF document. All content, annotations, and formatting are preserved.

ZIP PDF Files

Bundle multiple PDF files into a single ZIP archive. Drop your PDFs and download them as one ZIP file.

Extract Single PDF Page

Extract any single page from a multi-page PDF into a new single-page PDF. Choose your page number — all content and annotations are preserved.

N-Up PDF Tool

Arrange two PDF pages per sheet (2-up layout) on landscape A4 pages for efficient printing.

Add Image to PDF

Add an image to your PDF — choose position, size, opacity, and which pages. Perfect for logos, stamps, watermarks, and signatures.

Redact PDF

Automatically detect and redact sensitive data (SSN, email, phone numbers) from a PDF with black boxes.

OCR PDF (Make Scanned PDF Searchable)

Make a scanned PDF searchable. Each page is recognised with Tesseract OCR (compiled to WebAssembly) and an invisible text layer is overlaid so every word is selectable, copyable, and findable in any PDF viewer.

PDF Form Filler

Fill an interactive PDF form in your browser, then download the completed copy. Supports text, checkbox, radio and dropdown fields with an optional flatten step that locks every value into the page.

PDF Bates Numbering

Stamp legal-style Bates numbers (PREFIX-000001, PREFIX-000002…) onto every page of a PDF. Configure the prefix, start number, position, font and size for discovery-ready output.

PDF Add Hyperlinks

Make every URL, email and phone number in a PDF clickable. The tool scans the text layer, locates each match, and adds a standards-compliant link annotation over the corresponding rectangle.

PDF Accessibility Fixer

Add the basic accessibility metadata an assistive-technology user needs from a PDF: document language, title, and the marked-content flag. Quick mechanical fix for common WCAG / Section 508 audit failures.

PDF Advanced Merge

Merge multiple PDFs with per-file page-range selection and reordering. Pick exactly which pages from each input file go where in the output — the editor most "merge PDF" tools never expose.

PDF Annotator

Add highlights, underlines, strikeouts, freehand drawings and sticky-note text to a PDF. Annotations are written as standard PDF annotation objects — every standards-compliant PDF viewer renders them correctly.
