53 free PDF tools · no sign-up

The PDF workspace that never needs your upload.

Merge, compress, convert, edit, sign and OCR PDFs right in your browser. Fast, private by design, and free – no sign-up, no watermark.

Drop any PDF, Word, Excel or image

We’ll suggest the right tools. Files stay on your device.

Local-first processing

52 of 53 tools run entirely in your browser using WebAssembly builds of QPDF and Tesseract, PDF.js and pdf-lib. Your file is not uploaded for them.

Honest about the rest

PowerPoint conversion and the high-fidelity Office engine need a server. Every such tool is labelled before you start, and server copies are deleted as soon as the result is returned.

Built for batches

Drop in dozens of files and get one ZIP back. Pro removes the batch limit, and the developer API automates merging, compression, conversion and OCR from your own apps.

Free online PDF tools, built for speed and privacy

PDF Converter brings the everyday PDF jobs – combining files, shrinking them for email, turning them into Word or Excel, filling and signing forms – into one fast, focused workspace. Because the processing happens on your own device, there is no upload queue and no waiting for a server: a 100-page merge finishes in about the time it takes to click download.

Under the hood we use proven open-source engines rather than shortcuts. PDF.js renders and reads pages, pdf-lib edits document structure, QPDF handles AES-256 encryption, repairs and optimisation, and Tesseract recognises text in scans. Compression, grayscale and PDF/A conversion are our own engines built on these libraries. Where a job genuinely needs more – like reproducing a PowerPoint layout exactly – we say so and use LibreOffice on our server instead of producing a poor imitation.

Basic tools are free with no account. If you process documents every day, Pro removes ads and unlocks large batches, and the Developer API lets you automate PDF work from your own apps.
