Detailed walkthrough
1. Open signeee
Go to signeee.com/sign in any modern browser — Chrome, Safari, Firefox, or Edge. There is nothing to install. The signing engine loads once (about 1 MB) and is cached for repeat use.
2. Drop your PDF
Drag the PDF onto the page or click to choose it. signeee accepts standard PDF files (PDF 1.4 through PDF 2.0) up to 50 MB, including PDFs that already contain AcroForm signature fields. The file is parsed locally in your browser.
3. Let signeee detect the fields
signeee scans for both AcroForm signature widgets and visual signature lines using heuristics in 6 languages. Field labels like "Signature", "Unterschrift", "Firma", and "Handtekening" are all recognised. Detected fields are highlighted on the document.
4. Create your signature
Choose draw, type, or upload. Drawing works with finger, stylus, mouse, or trackpad. Typed signatures use one of several handwriting fonts. Uploaded signatures should be PNG with a transparent background for best results.
5. Click each field, then download
Click each detected signature field to place your signature there. Date fields next to signatures are auto-stamped with today's date. When done, click Download — signeee flattens everything into a standards-compliant PDF and saves it to your device.
Frequently asked questions
How do I sign a PDF online for free without an account?

The whole flow is free, requires no account, and runs entirely in your browser — your file is never uploaded to any server. Average completion time is about 10 seconds.
Can I sign a PDF on my iPhone or Android phone?
Yes. signeee works in any modern mobile browser — Safari on iPhone and iPad, Chrome on Android. You can draw your signature with your finger or a stylus. The signed PDF downloads directly to your device's Files app and can be shared via email, Messages, WhatsApp, or any other app.
Will the signed PDF open in Adobe Reader?
Yes. signeee outputs a flat, standards-compliant PDF that opens correctly in Adobe Reader, Apple Preview, Foxit, browser PDF viewers, and any other PDF software. The signature is rendered as a visible image on the page and the date is added as text — no proprietary signature container that requires special software to read.
Is a browser-signed PDF legally valid in the EU?
Yes. signeee produces an Electronic Simple Signature (EES) under eIDAS Article 3(10), which is legally recognised across all 27 EU member states. EES is sufficient for freelance contracts, NDAs, supplier and rental agreements, invoice approvals, and most internal sign-offs. EES is NOT sufficient for notarised deeds, marriage, real-estate transfers, or employment terminations.
