UseFreeTools

UseFreeTools is a free catalogue of 758 online tools across 15 categories, covering PDF merging and compression, image resizing and conversion, word counts and text comparison, CSV and JSON handling, unit converters, percentage and loan calculators, date math, fitness calculators and web helpers like a UTM builder. There's no account, download or sign-up. Most tools process files in your browser, and the ones that don't, such as Word to PDF and the AI tools, say so before you start. Server-processed files are removed after processing and their results expire within 15 minutes to an hour, according to the privacy page. The 38 AI tools send your input to the site's configured AI providers, which handle it under their own policies, so the site advises against submitting sensitive material. Search with Ctrl K, save favorite tools in the browser, or drop a file in to see matching tools without uploading it.
