About DocBlender

DocBlender is a small, focused workspace for everyday document chores: merging a stack of PDFs, splitting one into chapters, converting a Word file into a PDF you can email, compressing a scan that's too big to upload, signing a contract, generating a QR code. Every tool runs in the browser through a single, predictable interface — drop files in, pick an action, get a download.

Why we built it

Most online “PDF tools” either bury the actual conversion behind a paywall, require an account before letting you download, or load your files into an opaque desktop app you have to install. We wanted something honest: no signup, no installer, no upsell on the way to the download. The site funds itself through unobtrusive ads served by Google AdSense; everything else is free to use.

How files are handled

Each tool is a stateless HTTP endpoint that accepts your file, transforms it in memory, returns the result and discards the input. We do not write uploads to disk, do not maintain accounts, and do not keep copies for any purpose. The privacy policy has the full detail, including what cookies the advertising layer sets and how to opt out of personalised ads.
