📄 PDF Tools

PDF (Portable Document Format) is the standard format for distributing documents that need to look identical on any device or operating system. Working with PDFs — merging, splitting, compressing, rotating, and converting them — is a routine task in many professional and personal workflows. Most tools that can do this either require expensive desktop software, a subscription service, or upload your documents to a third-party server.

All PDF tools on this page are powered by pdf-lib and PDF.js — two mature, open-source JavaScript libraries for reading, creating, and modifying PDF files in the browser. pdf-lib handles document manipulation (merging, splitting, rotating, compressing), while PDF.js (Mozilla's PDF rendering engine, the same one used in Firefox) handles rendering PDF pages to images. Your documents never leave your device.

These tools are used by office workers who need to merge multiple scanned documents before emailing, students combining chapters from different sources into one study file, lawyers and accountants extracting specific pages from large documents, designers who receive PDFs and need to inspect individual pages as images, and anyone who needs to quickly reduce a PDF's file size before attaching it to an email.

When working with PDFs, keep in mind: the Merge PDF tool lets you drag to reorder files before combining them; the Split PDF tool can extract either individual pages or a custom range (e.g., "1-3, 5, 7-9"); the PDF to JPG tool lets you set resolution and quality; and the Compress PDF tool is most effective on PDFs generated by tools that do not apply stream compression, such as older software or scanned document exports.
