Tools for Everyone — Right in Your Browser

No uploads. No waiting. No sign-up. Everything runs locally on your device for maximum privacy and speed.

🖥️ Works Anywhere

File Tools runs entirely in your browser—no sign-ups, no uploads, no server round-trips. Works on Chrome, Firefox, Safari, and Edge across desktop and mobile. Open a tool, drop a file, and conversion happens locally for speed and reliability.

✅ Convert With Confidence

We support a wide range of everyday tasks—PDF editing and conversion, image compression, ZIP/TAR tools, OCR, spreadsheets, and DNS checks. Because everything is client-side, your files never leave your device and large jobs stay snappy.

🛡️ Privacy Guaranteed

Nothing you open here is uploaded. Processing happens inside the tab using WebAssembly libraries like pdf-lib, JSZip, LibArchive.js, and Tesseract. Close the tab and your data is gone—no accounts, tracking pixels, or hidden background syncs.

Your Data, Our Priority

We built File Tools to be useful without demanding trust. The app is a static site powered by Vite + React and served over HTTPS. Every tool avoids sending file bytes over the network. Preferences are stored locally in your browser and can be cleared at any time. For compliance-sensitive work, our browser-first approach minimizes data exposure by design.

About These Tools

How it works (client-side)
Each tool runs entirely in your browser using WebAssembly/JS libraries (pdf-lib, JSZip, LibArchive.js, Tesseract, etc.). No files are uploaded. Close the tab and your data is gone. This design is fast, private, and PCI-friendly.
Common use cases
  • Create or extract ZIP/TAR archives without installing software.
  • Compress PNG/JPG/WebP images before emailing or uploading.
  • Merge/split PDFs, or OCR a scanned PDF to make it searchable.
  • Check DNS records (SPF, DKIM, DMARC) for email deliverability.
Privacy & security
  • No server uploads; operations happen locally in the tab.
  • Transport is HTTPS; only lightweight analytics are used.
  • Preferences are stored in your browser and can be cleared anytime.
Supported platforms

Chrome, Edge, Firefox, and Safari on Windows, macOS, Linux, iOS, and Android. Large jobs benefit from a modern desktop browser.

Troubleshooting

A large file won’t load

Try a modern desktop browser, close other heavy tabs, and process in smaller batches.

PDF merge fails

Some PDFs are encrypted or malformed. Re-export the file, or merge in smaller chunks.

DNS results look inconsistent

Switch resolvers (Google/Cloudflare) and clear the cache. Propagation can take time.

Keyboard shortcuts

Offline friendly

Once loaded, many tools continue to work offline. Bookmark the page and reopen it even without a network.

Compliance notes

All processing is local to your browser. This architecture reduces data exposure for PCI and enterprise workflows.
