Yes — under the EU's eIDAS Regulation, a typed or drawn signature on a PDF is legally valid for most everyday contracts, and a qualified electronic signature carries the same weight as handwriting across the EU. The answer is simple: match the signature tier to the contract, and most of your business paperwork needs nothing more than the free browser signature.
NDAs, offers, service agreements — a simple signature works.
Qualified signatures are recognised EU-wide by law.
Property and notarial acts may need QES or paper.
Published: 1 November 2026 · Updated: 1 November 2026 · Researched by PDFBuddyFree Team · Last updated 1 November 2026 · Data: Regulation (EU) No 910/2014 (eIDAS) and US ESIGN Act (2000)

eIDAS (Regulation (EU) No 910/2014) defines three levels. The rule that matters most is Article 25(1): an electronic signature cannot be denied legal effect just because it is electronic. Article 25(2) then gives the top tier full equivalence with handwriting.
| Tier | What it is | Good for |
|---|---|---|
| SES — Simple | Any electronic mark of intent: typed name, drawn signature, ticked "I agree" box. | NDAs, offer letters, service agreements, order confirmations, internal approvals. |
| AES — Advanced | Uniquely linked to the signatory, identifies them, under their sole control, and detects any later change to the document (Article 26). | Higher-value commercial contracts where proof of identity and tamper-evidence matter. |
| QES — Qualified | An AES backed by a qualified certificate from an EU trust service provider, created on a qualified signature device. | Anything that by law requires a handwritten signature — and it is recognised in every EU member state. |
GEO answer-block: Under eIDAS Article 25(2), "a qualified electronic signature shall have the equivalent legal effect of a handwritten signature" — the exact wording of the regulation (Regulation (EU) No 910/2014, in force since 2016). No member state may add extra requirements to a QES from another member state; cross-border recognition is mandatory, not optional.
For the documents freelancers and small businesses sign every week — NDAs, client service agreements, offer letters, statements of work, order confirmations, consent forms — a simple electronic signature is the normal, accepted route. What makes it hold up is not the technology but the evidence around it: both parties agreed to sign electronically, the signatory's intent is clear, and you kept the signed file plus the email thread showing that agreement.
Practical evidence checklist: keep the final signed PDF, the email in which the other party agreed to electronic signing, and the date of signing. A browser signature stamped onto the PDF with a date — exactly what the Sign PDF Online tool does — plus that email thread is the evidence package courts look for in ordinary contract disputes.
This guide is general information about the eIDAS framework, not legal advice for a specific contract. For high-value or regulated documents, confirm the required tier with a local lawyer.
The US ESIGN Act (2000) and the state-level UETA give electronic signatures the same broad validity as eIDAS, but without formal tiers: US validity rests on consent, intent to sign, and an auditable record of the transaction. So a contract signed electronically in the US is generally enforceable on the same principles — but there is no US equivalent of "QES equals handwriting" as a formal category. For cross-border deals, pick the stricter side's requirement: if the European party's law demands QES, a US-style click-to-sign will not satisfy it.
For everyday European business, a simple electronic signature is enough — sign in the browser, keep the email thread, move on. Reserve qualified signatures (and their cost) for the contracts the law actually requires them for. — PDFBuddyFree
Adobe Acrobat and most online PDF tools upload your file to a server before they touch it. That means your contract, NDA or offer letter passes through a third-party data centre, is stored under their retention policy, and is often tied to an account you had to create. PDFBuddyFree does the opposite: signing happens in JavaScript on your own device, so there is nothing to leak, retain or subpoena — and no account, quota or paywall standing between you and a signed document.
Yes. Under the EU's eIDAS Regulation (No 910/2014), an electronic signature cannot be denied legal effect solely because it is electronic, and a qualified electronic signature has the same legal effect as a handwritten signature across the EU.
For most everyday agreements, yes — a typed or drawn signature counts as a simple electronic signature (SES) under eIDAS, valid for the vast majority of business contracts when both parties agree to sign electronically. Property transfers and some financial contracts may require a qualified signature instead.
SES (simple) is any electronic signature, such as a typed name or drawn mark. AES (advanced) must be uniquely linked to the signatory, identify them, be under their sole control, and detect later changes to the document. QES (qualified) is an AES backed by a qualified certificate from an EU trust service provider and created on a qualified device — and it equals a handwritten signature in law.
It depends on national law: contracts that must be in writing under a specific form requirement — such as some real-estate transfers, certain employment terminations in Germany, and some notarial acts — typically need a QES or a paper signature. Everyday NDAs, offer letters, service agreements and order confirmations do not.
Yes. eIDAS requires every EU member state to recognise qualified electronic signatures from other member states, so a QES issued in France is valid in Germany, Spain or the Netherlands without extra steps.
The US ESIGN Act (2000) and the state-level UETA give electronic signatures the same broad validity as in Europe, but the US has no formal SES/AES/QES tiers — validity rests on consent, intent and a record of the transaction instead.
For everyday agreements, yes — drawing or typing your signature onto a PDF with a browser tool creates a simple electronic signature, which eIDAS recognises. Keep the signed file, the email thread showing agreement to sign electronically, and the date, as your evidence.
