A contractor emailed me an NDA as a PDF. They wanted a signature "today." I had three bad options:
- Print, scribble, scan (and hope the scanner isn't broken)
- Upload the contract to DocuSign / Adobe Sign and hope their free tier still works
- Drop it into a random "free PDF signer" that quietly stores the file on a server
None of those felt right for a document with personal details and a non-disclosure clause. So we built a fourth path into EditDocx: e-sign (and fill) a PDF entirely in the browser — no account, no upload of document content to EditDocx servers.
Design mode: place a Signature field (pen icon) wherever the form expects ink.
E-sign vs "PDF editor" vs DocuSign
Language gets muddy here. Quick map:
| Need | What you actually want |
|---|---|
| Rewrite paragraphs in a PDF | A real PDF editor (Acrobat, etc.) |
| Multi-party workflow, audit trail, reminders | DocuSign / Adobe Sign / similar |
| Put your name, date, and a signature on a PDF you already have | Fill & Sign — what EditDocx ships |
EditDocx Fill a PDF is the third row. It is intentionally not a CLM / e-signature platform:
- No certificate-backed digital signatures (PKI)
- No sequential signer routing or legal hold
- No "send for signature" email workflow
It is the Adobe Fill & Sign style job: open the PDF, place fields, type or draw, download a filled PDF that stays on your device until you email it yourself.
Why signatures shouldn't leave your machine by default
A signature is identity. Combined with a contract, tax form, or medical intake PDF, it's high-stakes PII. Cloud e-sign products earn that trust with SOC reports and contracts — and they still require accounts and cloud copies.
For one-off "please sign and send back" attachments, routing the file through another SaaS is often overkill. EditDocx keeps the bytes in the tab:
- You open a local PDF (or a starter template)
- Rendering + signature capture use browser APIs
- Download writes a new PDF locally
Marketing pages may load analytics. Document content is not uploaded to EditDocx servers. Same privacy model as our DOCX / XLSX editors.
Walkthrough: sign in about a minute
1. Open Fill a PDF
Go to editdocx.net/pdf — no signup. Import your PDF, start from a blank page, or pick a template (invoices, certificates, labels).
2. Design: place the signature field
Switch to Design. From the left palette, choose Signature (and text / date / checkbox if the form needs them). Click the page where the signature block belongs. Resize if needed.
Fill mode: fields light up so you type and sign without fighting the layout.
3. Fill: type, then sign
Switch to Fill. Complete name and date fields. Click the signature field and draw or upload a signature image (depending on what the field UI offers). Treat this like wet-ink on a scan — visual evidence of assent, not a court-grade cryptographic seal.
4. Download and sanity-check
Hit Download PDF. Reopen the file in Preview, Adobe Reader, or Chrome. Confirm the signature sits where you intended and nothing important got clipped.
Same workspace pattern as EditDocx Word/Excel: Files on the left, canvas in the middle, Download when done.
Optional: Save keeps the layout in this browser's recent files (up to 10 items, 20MB each) so you can reuse the same form next week without redesigning fields.
When to use EditDocx vs DocuSign
| EditDocx Fill a PDF | DocuSign / Adobe Sign | |
|---|---|---|
| Account | No | Yes |
| File uploaded to vendor | No (editing path) | Yes |
| Multi-party routing | No | Yes |
| Audit / compliance trail | No | Yes |
| Price for one signature | Free | Free tier / paid seats |
| Best for | One-off NDAs, certificates, guest PCs | Formal vendor workflows |
Use EditDocx when someone sends you a PDF and you need to mark it up privately on this device.
Use DocuSign when you need to send a packet to five people, chase reminders, and keep an audit log your lawyer recognizes.
Who this is for
- Freelancers signing SOWs / NDAs without creating yet another SaaS account
- IT / support helping users on locked-down machines (no Adobe install)
- Anyone privacy-conscious dealing with HR, medical, or government PDFs
- Chromebook / shared-computer users who should download and leave no cloud trail
Limits (say them out loud)
- Not a full PDF editor — no rewrite / merge / OCR / unlock
- Not a replacement for legally mandated e-signature platforms when your jurisdiction or contract requires them
- Complex AcroForm PDFs can be awkward; Design-mode fields on top of a flat PDF cover most "print and sign" cases

If a form fights the field placement, say so in feedback — flat scans and weird crop boxes still surprise us.
Disclosure: I work on EditDocx. Fill a PDF is free; no account required.
