AltFTool vs PDF24

PDF24 is the closest thing to a peer in this list: free, unmetered, no watermark, no paid tier, funded by ads, with a clear one-hour deletion policy and EU hosting. The honest difference is architectural, not commercial. PDF24 uploads and processes server-side, which is why OCR and heavy compression work well there; AltFTool processes locally, which is why nothing is uploaded but also why big scanned files depend on your hardware. If uploading is not a problem for your document, PDF24 is a completely reasonable choice.

PDF24's free tier, in their own words

  • All online tools are free with no metering — the FAQ states the tools are available "to all users, including companies, free of charge and without restriction"
  • No artificial file-size or file-count cap: "There are no artificial limits at PDF24"
  • Funded by advertising: the service is "financed by means of discreet advertising on the websites"
  • Uploaded files are "automatically deleted from the processing server within one hour after processing", and can also be removed manually immediately
  • Files are processed on PDF24's own servers (EU data centres), with encrypted transfer — not in the browser

What PDF24 does better

Plenty of people should keep paying for PDF24, and these are the reasons why.

  • Genuinely unmetered: no daily task cap, no watermark and no paid tier at all, which is rare among hosted PDF suites.
  • PDF24 Creator is a free Windows desktop app that runs the same toolset fully offline, so files never leave the user's PC — a real answer for people who cannot upload documents.
  • Server-side processing comfortably handles very large or scanned PDFs (OCR, heavy compression) that can exhaust a browser tab's memory.
  • EU-hosted processing with encrypted transfer and automatic deletion inside an hour is a clear, specific privacy commitment rather than a vague promise.

And what AltFTool does not do

  • No OCR. PDF24 runs it server-side and does it well; we do not offer it at all.
  • No desktop app. PDF24 Creator gives Windows users the whole toolset offline, and there is no AltFTool equivalent.
  • Heavy compression on large scanned documents is where a server wins. On a big file, PDF24 will likely finish faster and squeeze harder.

Questions people actually ask

Both are free and ad-funded. What actually differs?
Where the file goes. PDF24 uploads it to an EU server and deletes it within an hour; AltFTool never receives it. If your objection to online tools is the upload itself, that is the whole difference.
Which is faster on a 200 MB scanned PDF?
Almost certainly PDF24. Server CPUs do not care how old your laptop is. Our compressor is limited by the memory a browser tab is allowed to allocate.
Does AltFTool have anything like PDF24 Creator?
No. There is no installable AltFTool desktop application. If you need a fully offline toolset on Windows, PDF24 Creator is the better answer.
