UseFreeTools

With any free file tool, the first question is where your file ends up. UseFreeTools answers it on every tool. Most of its 758 tools run in the browser, and any tool that uploads to a server says so before you start. Word to PDF, for example, is described as converting a DOCX on the site's server. You can even drop a file on the homepage to see which tools fit its type, and the site checks the file type on your device without uploading it.

The privacy page backs this up with specifics. Server-processed files go to an isolated worker after a Cloudflare human check and are removed after processing, and results expire 15 minutes after submission. Word to PDF downloads expire after an hour. The site uses cookieless analytics and says it runs no advertising scripts.

The 15 categories cover most small jobs. PDF tools merge, split, compress and convert. Image tools resize, crop, compress and convert formats, including HEIC. Text tools count words, change case and compare two versions. There are CSV and JSON converters and cleaners, 96 developer tools, unit converters, percentage, fraction and loan calculators, date-difference and age calculators, BMI and running-pace tools, and web helpers like a UTM builder, favicon generator and search-snippet preview.

The 38 AI tools, including a writing editor, a text translator and a resume-to-job match checker, work differently. They send what you submit to the site's AI providers, and if one provider fails another may receive the same input. Those providers may keep data under their own policies, so the site asks you not to submit sensitive or third-party material. Inputs and results sit in encrypted temporary storage and expire within an hour.
