seal.hu is an electronic signature and document management platform for the Hungarian market, positioned as an all-in-one browser-based tool for the workflow “from upload and signing to archiving.” Users can upload PDFs, configure signers, signing order, and signature/date fields, then send email links for recipients to complete the signing process. Signers do not need to register or install software, and can sign in modern browsers and on mobile devices.
The platform focuses on the electronic signing workflow: drag-and-drop PDF upload, adding signers, placing signature fields, initiating signing by email, automatic reminders, document archiving, and complete audit logs. On the security side, seal.hu uses PAdES digital signatures, embeds encrypted certificates in PDFs, supports signature validation in PDF readers such as Adobe Reader, and states that it uses eIDAS-compatible Advanced Electronic Signatures (AdES). Audit logs record IP addresses, timestamps, and device information. It can also require signers to photograph both sides of an identity document for identity verification. The site also mentions EU server storage and GDPR-compliant data processing.
Pricing is fairly straightforward: the free plan includes 5 documents per month; Standard costs 2490 Ft/month and includes 20 documents; Pro costs 6990 Ft/month and supports unlimited documents. Typical use cases include real estate purchase and lease agreements, HR employment contracts and NDAs, internal policy acknowledgements, service agreements, quotes, and order signing. It is particularly suitable for SMEs that need a Hungarian-language interface, local support, and pricing in Hungarian forint.
The strengths are ease of use, no installation required, no account required for signers, and baseline compliance capabilities such as PAdES, eIDAS AdES, GDPR, and audit logs. The free plan and low-cost tiers also lower the barrier to adoption. Limitations include the lack of disclosed API, Webhook, third-party integrations, bulk automation, or self-hosting capabilities. The platform also notes that some scenarios, such as real estate transactions and notarized documents, may require QES qualified electronic signatures, so it cannot simply replace every legal signing scenario.
The available information does not state how well the service works from mainland China, so access is unknown. Payment methods are also not disclosed; the only confirmed detail is that pricing is in Hungarian forint. If a Chinese company primarily needs domestic contract signing, it will usually also need to compare local compliance and real-name verification capabilities, with options such as e签宝, 上上签, and 法大大. For companies operating in Europe or locally in Hungary, seal.hu’s local language support, EU data storage, and forint-based pricing may be more attractive.
