PDF Tools

Free, browser-based PDF utilities to convert, rotate, crop, split, merge, reorder, and paginate your documents. Safe and private processing — files never leave your device.

How to use these PDF tools

Our PDF tools are designed to be fast, simple, and private. To get started:

  1. Select the tool you need from the grid above (e.g., Rotate PDF, Crop PDF, or Add Page Numbers).
  2. Drag and drop your PDF file (or PNG images for the converter) directly into the dashed dropzone area.
  3. Configure the options for your document, such as picking rotation angles, setting margin crop values, entering page ranges, or setting page number placements.
  4. Click the main action button. The processing is done instantly and entirely inside your browser.
  5. Click Download to save the modified PDF file directly to your device.

100% Private Client-Side Processing

Standard online PDF editors require you to upload your files to their remote servers, which raises serious concerns about privacy and document security. Our suite of PDF utilities is different:

  • No Uploads: Files are read directly from your local file system into browser memory as binary array buffers.
  • Browser-Side Compiles: We use the advanced open-source pdf-lib library to modify page dictionaries, apply rotations, define crop boxes, and copy pages entirely within the browser's JavaScript engine.
  • Offline Mode: Once the page is loaded, you can disconnect your internet completely and the tools will continue to work perfectly.

Yes, 100% safe. Because all processing occurs locally in your browser, your files never leave your computer. There are no server uploads, no data storage, and no risk of data leaks. You can even use these tools completely offline once the page has loaded.
