Free Online Tools That Work Offline
Need to get work done with no internet? Chito Tools utilities run entirely in your browser — so once the page loads, most tools keep working offline. Your files never leave your device.
Why these tools work without internet
Because every tool processes files locally in your browser, there is no server request involved in the actual work. Once the page and any needed assets have loaded, merging PDFs, resizing images, and more continue to function even with the connection dropped.
This is also the strongest proof of privacy: if a tool works offline, your files are provably not being sent anywhere.
Which tools work offline
PDF merging, splitting, rotating, and converting, image resizing and format conversion, background removal, QR generation, unit conversion, JSON formatting, password generation, word counting, and Base64 encoding all run locally.
Note: OCR loads its language model on first use, so the very first OCR run needs a connection; after that, the model is cached and OCR works offline too.
Frequently Asked Questions
Do the tools really work offline?
Yes. Once the page loads, tools like PDF merging, image resizing, and QR generation work without an internet connection.
Does OCR work offline?
After the first run downloads and caches the language model, OCR works offline for subsequent scans.
Why does offline support matter for privacy?
A tool that works offline is proof that your files are processed locally and never uploaded to any server.
