Every page below compares AltFTool with one specific product: what its free tier actually allows, what the paid plan costs, where your file goes, and — the part most comparison pages skip — what that product still does better than we do.
The figures come from each vendor's own pricing, help and privacy pages, with the sources listed on the page and the date they were read. Several of these are excellent products that many of our readers pay for and should keep paying for. Where that is the case, the page says so.
Most tools on this list upload your file to a server, process it there, and delete it some hours later. That is why they can OCR a scanned archive or encode a two-hour video, and it is also why they meter you — someone is paying for that compute. AltFTool's tools are JavaScript and WebAssembly that your browser downloads and runs locally, so nothing is uploaded and nothing needs counting. The cost is real: no OCR, no server-scale file sizes, no API, no saved work. Each page below states which of those matter for that specific product.
