A lot of European business owners and legal teams search for "is SignNow eIDAS compliant?" and "eIDAS-compliant e-signature" when they need to sign documents across EU borders. The short answer: eIDAS recognizes three levels of electronic signature — SES, AES, and QES — and which one you need depends entirely on the document you're signing. This guide explains what eIDAS compliance actually means, how tools like SignNow, DocuSign, and free online signature generators fit into it, and when a simple typed or drawn signature is perfectly legal.
What is eIDAS?
eIDAS (Regulation (EU) No 910/2014) is the European Union's legal framework for electronic identification and trust services. It applies across all 27 EU member states and the wider EEA, and its core rule is simple: an electronic signature cannot be denied legal effect solely because it is in electronic form. In practice, this means a signature you draw, type, or upload online is legally valid for contracts and documents throughout Europe — provided the parties consented to signing electronically.
The three eIDAS signature levels: SES, AES, and QES
eIDAS defines three levels of electronic signature, with increasing assurance:
- Simple Electronic Signature (SES) — any electronic data attached to or logically associated with a document. A drawn signature, a typed name, or a scanned image pasted onto a PDF all qualify. This is what free tools create, and it covers the vast majority of everyday documents.
- Advanced Electronic Signature (AES) — uniquely linked to the signer, capable of identifying them, created with signer-only control, and linked to the document so any later change is detectable. Providers like SignNow and DocuSign offer AES as part of their standard signing flows.
- Qualified Electronic Signature (QES) — an AES created with a qualified certificate from a trusted list of certification authorities and a secure signature creation device. A QES has the same legal effect as a handwritten signature in every EU member state.
Is SignNow eIDAS compliant?
Yes — according to airSlate SignNow's public documentation and marketing materials. SignNow advertises eIDAS-compliant signatures including Advanced (AES) and Qualified (QES) signatures, with signing backed by a trusted digital certificate issued by airSlate and verified through Adobe's certificate authority. If you need a QES for a specific document, SignNow is one of the mainstream providers that offers it — along with competitors such as DocuSign, Adobe Acrobat Sign, and Dropbox Sign, which also document QES support.
Important caveat: compliance features are often tied to specific plans, regions, and the document type. Always check the provider's current compliance documentation (and ideally a qualified trust service provider list from your member state) before relying on a QES for a critical filing.
Where free tools fit: when is a simple signature valid?
Because eIDAS treats SES as legally valid, a signature created with a free tool — like drawing or typing your name in the i hate signature generator — is a valid electronic signature for most documents, including:
- Client contracts, service agreements, and invoices
- NDAs and confidentiality agreements
- Employment offers and HR consent forms
- Lease agreements and purchase orders
- University applications and student consent forms
The one legal requirement that always applies is consent: all parties must agree to conduct the transaction electronically. As long as that's satisfied, a simple electronic signature holds up.
When you actually need AES or QES
Upgrade to AES or QES when:
- The document is a public-sector filing that a government body in your member state requires to be qualified;
- The receiving party explicitly requests an advanced or qualified signature;
- The document is regulated by law to need a qualified signature (some court filings, notarized instruments, and certain immigration or HR documents fall into this category in specific countries);
- You want the extra tamper-evidence and audit trail that AES/QES provide for high-value contracts.
For everything else — and that's the overwhelming majority of everyday signing — a simple drawn or typed signature is legally sufficient, which is why free, browser-based tools are a legitimate choice for most users.
What about the United States? (ESIGN & UETA)
US law works differently. The ESIGN Act (2000) and UETA, adopted in 49 states, give electronic signatures the same legal weight as ink signatures — and US law has no SES/AES/QES hierarchy. A drawn, typed, or uploaded signature is valid for virtually all commercial documents, from contracts and NDAs to real estate and loan paperwork. For a deeper comparison of how the two legal systems handle e-signatures, see our earlier guide on whether electronic signatures are legally binding.
Practical takeaway: which level do you need?
- Everyday contracts, NDAs, invoices, forms → SES. A drawn or typed signature from a free tool is legally valid. Just make sure everyone consented to electronic signing and you keep a copy of the signed file.
- High-value deals or audit trails → AES. Use a provider's standard signing flow, which adds signer identity checks and tamper detection.
- EU public-sector or regulated filings → QES. Use SignNow, DocuSign, Adobe, or a national qualified trust service provider, and confirm the requirement with the receiving authority first.
