About PDF Tools
PDF Tools brings together the essential operations people need when working with PDF documents — not a full desktop PDF editor, but 13 focused tools that each handle one specific task well: merging several PDFs into a single file, splitting out specific pages, compressing a PDF to fit under an email attachment limit, rotating pages that came out sideways from a scanner, extracting plain text for reuse, converting PDF pages into images, turning images into a PDF, adding a watermark or password protection, and converting between PDF and Microsoft Word formats.
Every tool here runs entirely in your browser, using the HTML5 Canvas API and modern JavaScript PDF libraries — nothing is uploaded to a server to be processed, merged, compressed, or converted. This matters for PDFs more than for almost any other kind of file: a PDF can contain contracts, financial statements, medical records, legal documents, or private correspondence, and this category is built so none of that ever has to leave your device just to perform a routine operation. The trade-off is that everything is limited to what a browser can handle locally — which, for the 13 tasks covered here, turns out to be nearly everything most people need day-to-day.
The tools fall into three natural groups. Basic operations (PDF Merger, PDF Splitter, PDF Rotate, PDF Page Counter) cover the fundamental actions everyone reaches for when organising a multi-page document: combining chapters or appendices, extracting just the pages you need, fixing a scanner's sideways output, or quickly counting how many pages a file contains before printing. Compression and security (PDF Compressor, PDF Password Protect, PDF Watermark) handle the protective concerns around sharing PDFs: reducing file size to email or upload, encrypting with a password so only the right person can open it, and stamping a CONFIDENTIAL or company logo watermark across every page. Conversion tools (PDF to Images, Images to PDF, PDF to Text, PDF to Word, Word to PDF, PDF Crop & Resize) move documents between formats or adjust their dimensions — extracting JPG/PNG images from each page, assembling a collection of scanned images into a tidy single PDF, pulling out plain text for copy-paste into another document, converting a PDF into an editable Word .docx file (with the important caveat that scanned or image-only PDFs require OCR, which is not yet available here), converting a .docx back into a clean PDF, or cropping margins and resizing pages to standard paper sizes.
PDF processing in a browser is inherently more resource-intensive than text or math tools — a 100-page PDF with high-resolution images can consume significant memory. The tools include file size warnings, and the site-wide maximum upload size (configurable by the administrator) defaults to 50 MB. For exceptionally large documents, consider splitting them first with the Splitter tool and processing the parts separately.
All processing is local. Your files are read into memory, processed by JavaScript running in your own browser tab, and the result is downloaded directly — nothing transmitted, nothing stored, nothing logged. The page itself is served over a secure HTTPS connection, but the PDF data path never involves the server at all, making these tools safe for sensitive documents that cannot be shared with any third-party service.
