Protool is a privacy-first collection of more than 25 free online utilities for working with images, PDFs, and everyday documents. Every tool runs entirely in your browser, which means your files never leave your device — no uploads, no accounts, no watermarks, and no daily limits.
Most online file tools upload your documents to a remote server, leaving you to trust a third party with sensitive content like bank statements, ID cards, signed contracts and personal photos. Protool takes a different approach: every operation — image compression, PDF merging, background removal, passport-photo generation, resume building — runs locally in your browser using modern web technologies. There is no file upload, no server-side storage, and no account to create.
Each tool is documented with step-by-step instructions, frequently asked questions, and detailed notes on output quality, supported formats, and country-specific requirements where applicable. Visit the Protool blog for in-depth guides on choosing image quality settings, compressing PDFs without losing text, building an ATS-friendly resume, and more.
