AltFTool vs Zamzar

Two files per 24 hours is the tightest free tier in this list, and it is deliberate: Zamzar's catalogue runs past 1,100 formats, and running CAD, 3D and ebook conversions costs them real compute per file. If you need one of those formats, nothing here helps and you should pay them. If you are converting a phone photo to JPG or a set of images into a PDF, those run in your browser instantly and repeatedly, which is what the free-tier counter was standing in the way of.

What Zamzar does better

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

  • One of the largest format catalogues anywhere - the homepage claims 1100+ formats, including CAD, 3D, archive and ebook conversions that are impractical or impossible to run in a browser.
  • Straightforward for non-technical users: no login for the free service, results delivered to a file inbox, 5-100 GB of online storage on paid plans, and a documented conversion API - plus a long track record and stable, well-indexed conversion pages.
  • Clear, conservative retention: the original file is deleted as soon as it is converted and the converted copy is held only 24 hours, which is stated plainly in their FAQ rather than buried.

And what AltFTool does not do

  • 1,100+ formats versus our short list. CAD, 3D, archive and ebook conversions are not possible client-side.
  • No file inbox and no cloud storage. Zamzar's paid plans keep 5–100 GB of results; we hand you a download and keep nothing.
  • No email delivery for long jobs — if the tab closes mid-conversion, the work is lost.

Questions people actually ask

Is there a two-files-a-day limit on AltFTool?
No. Zamzar's limit rations server capacity across 1,100+ formats. Our converters run in your browser, so repeat use costs nothing and is not counted.
Can AltFTool convert a DWG or an EPUB?
No. Those need decoders that only exist server-side. Zamzar's catalogue is the reason their free tier is small, and it is the reason to use them for those formats.
Where does my converted file go?
Straight to your downloads folder. There is no inbox and no stored copy — Zamzar keeps output for 24 hours, we keep it for zero seconds.
