Last month I needed to fill out a certificate PDF on someone else's laptop. No Adobe license, no time to install anything, and the file had a sensitive contract number on it. I didn't want to upload it to a random "free PDF editor" either.
So we shipped Fill a PDF on EditDocx — a browser-only workflow that keeps the document on your device.
What it does (and doesn't)
Fill a PDF is intentionally narrow:
- ✅ Open a PDF from your computer (or start from a template / blank page)
- ✅ Place text boxes, dates, images, and signatures in Design mode
- ✅ Switch to Fill mode, complete the form, download
- ✅ Optional recent files saved locally in the browser (up to 10 items, 20 MB each)
It is not Acrobat:
- ❌ No rewriting existing PDF paragraphs
- ❌ No merge, split, compress, unlock, or OCR
Think Adobe Fill & Sign, not a full PDF editor. If you need Word/Excel editing, EditDocx covers that on the same site with the same privacy model.
Why client-side only?
PDF forms often carry PII — names, addresses, tax IDs, signatures. Routing bytes through a server "for convenience" creates a trust problem you can't code away with a privacy policy.
EditDocx PDF Fill runs entirely in the tab:
- You pick a file → it stays in memory / IndexedDB on your device
- Rendering and field placement use browser APIs
- Download produces a new PDF locally
Marketing pages may load analytics, but document content is not uploaded to EditDocx servers. That matches how we handle DOCX/XLSX/PPTX elsewhere on the site.
60-second walkthrough
- Go to editdocx.net/pdf — no signup
- Choose a starter template, blank page, or open your PDF
- Design: drop fields where they belong
- Fill: type, sign, check boxes
- Download
If you'll reuse the same form, it lands in Recent files in that browser until you clear site data.
Templates included
We ship several starters (invoices, certificates, address labels, etc.) — useful when you want a repeatable layout instead of marking up someone else's PDF every time.
Who is this for?
- IT / support: help users on locked-down machines without installing Adobe
- Freelancers: sign statements of work or NDAs without emailing PDFs to SaaS vendors
- Anyone privacy-conscious: HR forms, medical intake, government PDFs
Tech notes (for the curious)
The PDF Fill workspace is a separate route from the Word editor, lazy-loaded so the main DOCX bundle stays lean. Field editing builds on pdfme-style plugins; filled output is generated client-side before download.
We also published an Agent Skill for AI tools that need to point users to the right URL — useful as more agents help people complete paperwork.

If you hit a PDF with a weird layout, let us know — complex forms sometimes need a sanity check after download. We're improving edge cases, but the happy path (name, date, signature on a standard form) is what we optimize for.
Disclosure: I work on EditDocx. The tool is free, no account required.
