About FileToolsHub

Free online tools for everyday file and text work — built to be fast, simple, and private.

FileToolsHub is a free web hub for PDF, image, spreadsheet, text, AI, calculator, audio, and browser tools. Merge and compress PDFs, convert images, transform CSV/Excel/JSON, summarize or rewrite text, and run developer utilities — without installing software.

Facts at a glance

  • 644 public tools with stable URLs under /tool/…
  • Categories: PDF (27), Image (73), Spreadsheet (6), Text (413), AI (11), Calculator (74), Audio (14), Browser (26)
  • About 594 tools run entirely in your browser (formatters, many image editors, calculators, audio, browser checks) — input never uploads
  • Upload-backed converters (PDF jobs, some image/spreadsheet conversions) process securely; temporary files are removed after the job — max upload about 25 MB per file for standard jobs
  • AI tools (summarize, rewrite, wallpaper, upscale, etc.) send text or images to FileToolsHub AI for that request only — they are not browser-local
  • Everyday use is free, no install; light guest limits apply on upload jobs (higher with a free account)
  • Canonical site: https://filetoolshub.com

Privacy model (browser vs upload)

Browser-only: text formatters, encoders, hashes, calculators, many canvas image editors, audio tools, and device checks run in JavaScript in your tab. Drafts and secrets never cross our network.

Upload for the job: PDF merge/split/compress and similar converters upload only long enough to finish, then temporary storage is cleared. Read the full policy on Privacy. For product or privacy questions, use Contact.

AI-assisted: labeled AI tools call our AI service with your pasted text or uploaded image. Prefer browser-only tools when the content must not leave the device.

Who runs FileToolsHub

FileToolsHub is an independently operated free tools site at filetoolshub.com. Product and privacy questions go to hello@filetoolshub.com. We built the catalog so everyday PDF, image, spreadsheet, and text jobs stay free, documented, and reachable at stable /tool/… URLs — without forcing an install or account for normal use.

Who it is for

FileToolsHub is for students, freelancers, office teams, and developers who need a reliable converter or formatter without a heavyweight suite. Chain focused tools — merge → compress → protect — in any order. For a side-by-side with desktop PDF apps, see PDF online vs desktop for quick edits.
