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.
Concretely: uploads arrive over HTTPS, are held in a per-request memory buffer for as long as the conversion takes (usually well under a second), and the buffer is released back to the operating system as soon as the response is sent. There is no queue, no background worker writing temp files, and no logging of file contents. We don't look at your documents, and we couldn't retrieve them after the fact even if you asked us to.

Tech
The frontend is Next.js (App Router) with React 18 and Tailwind. The PDF heavy lifting is done by pdf-lib and pdf.js; images go through sharp; Word documents are read with mammoth and written with docx. The site is hosted on Vercel.
What we don't do
We deliberately keep the scope narrow: convert, combine, split, compress, sign, watermark, generate. There's no document storage, no team workspace, no collaboration features and no AI-generated content. Every tool maps to one well-defined operation that we can implement reliably and explain in one sentence. If you need a permanent home for documents or a collaborative editor, we're not the right fit — and we'd rather tell you that than try to be everything.
Our commitments
- No signup, ever. You should be able to land on a tool, drop a file, get a result and leave — without an account, without a free trial, without a verification email.
- No paywall on the result. Every tool produces a real, usable output. We don't watermark free downloads or cap the page count.
- Honest privacy. Files are processed in memory and discarded. We say so on the home page, in the privacy policy and here — because it's true, not because it sounds nice.
- Ads stay out of the way. The site is funded by Google AdSense placements that sit beside the tool, not on top of it. The conversion button is always visible without dismissing anything.
Who's this for?
Mostly individuals and small teams who need to handle a document chore and move on: students assembling submissions, freelancers sending invoices, applicants compiling supporting documents, small business owners signing contracts, and anyone who just wants to rotate an upside-down scan without installing software. If you do this kind of work more than a few times a week, the bookmark bar is a good home for the tool you reach for most.
