Small tools, kept small on purpose

File Toolbox is a set of single-purpose tools for the file-format problems that come up constantly: a PDF that needs to be an image, a photo that needs to be a smaller file, a screenshot that's the wrong format for an upload form. Each one does exactly one job and gets out of the way.

Why it runs in your browser

Every conversion here — image format changes, compression, PDF rendering, PDF assembly, text extraction — happens using standard browser APIs (Canvas, the File API, and the open-source pdf.js and jsPDF libraries) directly on your device. Your files are never sent to a server, which means no upload wait, no file-size limits imposed by a backend, and nothing to worry about in terms of who else might see your documents.

About the format list

PDF/image conversion in general covers a huge range of formats — Word, Excel, PowerPoint, EPUB, CAD, vector formats, and OCR-based text extraction from images. Those all require a real conversion engine (and usually OCR), which can't run entirely offline in a browser the way our current tools do. We're evaluating adding them as clearly-labeled, server-backed conversions rather than shipping something that looks free but doesn't actually work — nothing on this site currently claims to do those conversions.

Who built this

File Toolbox is an independent, ad-supported project built and maintained by a small team that uses these exact tools day to day. If something breaks or a format you need is missing, the contact page is the fastest way to reach us.

What it isn't

This isn't a document-management platform or a place to store files — nothing you convert here is saved anywhere. If you need OCR, editable PDF-to-Word conversion, or e-signatures, this toolbox intentionally doesn't try to cover that ground yet; we'd rather do a handful of things well than twenty things poorly.
