Ad-supported free PDF toolbox online, plus a free offline Windows app

Prices verified October 30, 2026 on the vendor's site

Overview

PDF24 is a free PDF suite from geek software GmbH, a Berlin company founded in 2006. It comes in two forms. PDF24 Online Tools runs in any browser, with a long catalog covering merge, split, compression, editing, annotation, form filling and creation, OCR, redaction, comparison, PDF/A and broad conversion to and from Office, OpenDocument, images, EPUB and Markdown. It also includes niche tools for e-invoices and PDF signature verification. PDF24 Creator is a free Windows 10/11 app that bundles the same tools offline along with a virtual PDF printer, reader and scanner import. It is free for commercial use and offers an MSI installer for corporate rollout. There are no paid tiers, and the vendor says it pays for the service with ads on the website. The trade-offs: the desktop app has no Mac or Linux version, and no mobile app or AI features are listed.

Who it's for

Budget-conscious individuals, schools and businesses that need everyday PDF conversion, OCR and page work at no cost. Windows offices that want an offline, deployable tool for data-protection reasons are an especially good fit. Mac and Linux users are limited to the browser tools.
