Which PDF tool do I need?

Common PDF workflows

  • Assembling a document pack: merge the files, rearrange or delete pages, then compress it for sending.
  • Digitising paperwork: scan the pages, fix the order, make it searchable with OCR, then compress.
  • Working with a protected file: unlock it first, make your changes, then protect it again as the last step.
  • A blurry scan: sharpen it first, then run OCR on the sharper pages.

What stays on your device

Merge, split, rearrange, image to PDF, scan to PDF, standard OCR and the free compressor all run in your browser, so your files are never uploaded. A few tools need a server: Protect and Unlock process the file on ours and don't store it, and the AI tools (AI OCR and Upscale PDF) send pages to an AI service. Each tool's page says which applies, and you can read more in our guide to using PDF tools without uploading your files.
