Drop in a Word .docx and get back a clean, print-ready PDF that looks exactly like your document — tables, columns, images, fonts, and page breaks intact. No account, no install, no add-in. It just runs in your browser.
Every other free converter uploads your file to a server to do the work. nimbril does it all on your device, so your contract, offer letter, or patient record is never transmitted, stored, or used to train anything. Flip on airplane mode and it still converts — that's the proof your document never left your machine.
Add a Word document straight from your computer. It loads into the browser tab with no upload step, so even confidential drafts stay on your device. Only modern Word .docx (Office Open XML) files are supported.
nimbril lays your document out into real pages — honoring fonts, tables, images, columns, and page breaks — exactly the way Word would print it. Nothing about this round-trips to a server.
Get a single, faithful PDF that mirrors your Word layout, ready to email, file, or hand into another nimbril tool. It's generated locally and downloaded straight to your device.
An engagement letter or NDA drafted in Word needs to go out as a locked-down PDF that won't reflow on the recipient's machine. Convert renders it to a faithful, print-ready PDF entirely in the browser, so the privileged draft never passes through a third-party server. Hand the result straight into nimbril's Sign or Redact tools without it ever leaving your device.
Offer letters, handbooks, and policy docs live in Word but get distributed as PDFs so they look identical to everyone. Convert keeps the candidate's or employee's personal details on your machine rather than uploading them to a free online converter. Free, no signup, and the layout matches what you see in Word.
A care summary or intake form written in Word contains PHI and can't be pasted into a random website. Because Convert decodes and renders the file on-device and never uploads it, the document stays inside your HIPAA boundary while you produce a clean PDF for the record. Airplane mode proves nothing was sent.
Monthly reports and invoices authored in Word need to be archived as faithful PDFs that print consistently. Convert produces a page-accurate PDF locally, so client and vendor figures never touch an outside server. Pair it with nimbril's Merge or Compress tools to finish the workflow without an upload.
Most free Word-to-PDF converters work by uploading your .docx to their servers, rendering it there, and sending a PDF back — which means the full text of your document, including everything you'd never paste into a website, sits on a stranger's machine. Word files are exactly the documents most likely to be sensitive: contracts, offer letters, medical summaries, financial reports, legal drafts. nimbril renders everything in your browser, so the file is never transmitted, never stored, and never used for training. You can prove it by switching on airplane mode mid-conversion: it still works.
nimbril converts by laying your document out into real, pixel-perfect pages and rasterizing each one into the PDF — effectively the same as printing your Word file to PDF. The upside is high-fidelity layout: tables, columns, images, fonts, and page breaks land exactly where Word puts them, and the result looks identical on any device. The trade-off is that the text becomes part of the page image, so it isn't selectable, searchable, or copyable in the resulting PDF. If you need a PDF with live, searchable text, the right tool is Microsoft Word's own Save As / Export to PDF. If you need a faithful, ready-to-send snapshot without uploading your file anywhere, this is the tool.
No. The entire conversion runs in your browser, so your .docx never leaves your device — it's never uploaded, stored, transmitted, or used for training. You can switch to airplane mode and it still converts, which is the proof. That's why it's safe for NDAs, contracts, and HIPAA-sensitive files.
No — and we want to be straight about this. The PDF is image-based: each page is rendered to look exactly like your Word document, the same as if you printed to PDF, so the text inside is not selectable or searchable. You get pixel-faithful layout in exchange for that trade-off. If you need selectable text, export to PDF directly from Microsoft Word.
Very. We render your document into real pages and honor fonts, tables, columns, images, and page breaks, so the PDF looks like your Word doc on paper. Unusual fonts, macros, tracked changes, or complex form fields may render differently, so it's worth a quick glance before you send it.
Yes — you can convert Word to PDF free with no signup. The free tier handles documents up to 25MB (15MB on phones). Pro ($9/mo or $69/yr) raises the limit to 100MB for large documents, removes the watermark, and adds unlimited history across every nimbril tool. A single-app plan is $4/mo.
Modern Word .docx files (the Office Open XML format from Word 2007 onward). The older binary .doc format isn't supported — open it in Word and re-save as .docx first, then convert it here.
Yes. Because the rendering and PDF assembly all happen on your device, you can disconnect from the internet entirely and still convert your document. Working offline is the unfakeable proof that your file is never uploaded.
