About this toolbox

The Toolbox is a set of small file and text tools published by FreeOnlineBox. Each one is a static page that performs its work inside your browser, which is why there is no upload, no quota, no account and no paid tier.

How a tool can work without a server

Browsers have shipped the building blocks for real file work for years. The Canvas API reads and re-encodes images. Web Crypto computes hashes. WebAssembly runs PDF and OCR engines that used to require a backend. None of these need a round trip, so a page can open, do the work and hand the result back without the bytes ever leaving the machine.

That is a different kind of guarantee from a privacy policy. A site that uploads your file and promises to delete it is asking you to trust its retention process. A tool with no upload path has nothing to delete, and you can verify the claim from your own browser's network panel.

What this toolbox does not do

It does not convert Office documents to PDF.Faithful DOCX, XLSX and PPTX rendering needs a full office layout engine. Running one means a server and a bill, which is exactly what this toolbox is built to avoid.
It does not transcode video or audio.The codecs that make that work are large, slow on phones and carry their own licensing questions.
It does not open CAD, PSD or camera raw files.Those parsers are commercially licensed, and a partial implementation would corrupt files rather than convert them.
It does not count, rate or rank anyone.There are no user counts, no ratings and no success rates on these pages, because we do not measure them.

Third-party code and advertising

The tools are built on open-source libraries that permit commercial use: pdf-lib (MIT), pdf.js (Apache-2.0), Tesseract.js (Apache-2.0), the QR encoder (MIT) and ONNX Runtime Web (MIT). Recognition data for the OCR tool and the segmentation model for background removal are served from this domain rather than a third-party CDN, so the tool engine itself makes no third-party request and never receives your files.

Advertising is separate from the tools. This site loads Google AdSense on every page; Google and its partners may use cookies to serve ads based on your visits to this and other sites. Those scripts never receive the files or text you work with. You can opt out of personalised advertising at Google Ads Settingsor aboutads.info.
