Free alternatives to the tools you already use
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.
The one structural difference
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 made the opposite trade for the jobs these comparisons cover. File tools (PDF, image, converters) run in your browser and the file is not uploaded. Tools that need live data or a model — AI tools, language checkers, lookups — send your input to an API, and say so on their own page. The cost of that trade 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.
