Free tools that run right in your browser
With 99tool, you don’t need to download anything or create an account just to try a feature. The tools are designed to work in your browser, so you can go from idea to result quickly. It’s especially helpful when you’re on a deadline and don’t want setup steps getting in the way.
PDF tools that cover the common workflow
PDF work is everywhere—school forms, business documents, invoices, and more—and 99tool puts practical PDF utilities in one place. You’ll find a flagship suite of options like PDF Annotation & Editor for highlighting and adding notes, plus tools to merge, split, compress, and reorder pages. There are also converters and editors such as PDF to Image, Image to PDF, and a PDF Metadata Editor to manage properties privately in your browser.
If your PDF is locked down, 99tool also offers PDF Password Protector and an Unlocker flow, along with viewing and reading tools to navigate files smoothly. For data extraction, there’s a PDF Text Extractor, and for structured output, a PDF to Excel Converter and other conversion options that fit real workflows.
Image and file utilities for quick, practical edits
Beyond PDFs, 99tool includes image tools made for everyday needs. You can bulk resize images to consistent dimensions, and you can compress images to reduce file size while maintaining quality across popular formats like JPEG, PNG, and WebP. For teams and creators, these speed boosts matter—especially when you’re preparing files for web posts, uploads, or presentations.
The overall experience is straightforward: pick a tool, complete the task, and move on. That’s a simple design principle, but it’s one many sites forget.
