Why Opsily Wins for Fillable Forms
DocuSeal on Opsily handles PDF form conversion better than Adobe, DocuSign, or standalone tools.
Convert PDFs to Fillable Forms Instantly
Upload your PDF. DocuSeal scans it and automatically identifies signature boxes, text fields, checkboxes, dropdowns, and date pickers. No manual field placement. No guessing. Takes seconds instead of minutes.
No Per-Envelope Fees
Adobe Acrobat Pro costs $20/month. DocuSign charges $2.50+ per envelope or $400+/month. DocuSeal's free tier offers unlimited documents with zero watermarks. Managed Opsily hosting starts at $20/user/month. Send 100 forms or 10,000—same price.
GDPR-Compliant Hosting
Opsily runs DocuSeal on German servers. Your documents stay in the EU. Meets GDPR Article 32 technical safeguards. No data transfer to US without explicit consent. Perfect for enterprises with compliance requirements.

Open-source document signing and e-signature platform
Static vs. Fillable PDFs
A static PDF is a read-only document. A fillable PDF has interactive form fields (text boxes, checkboxes, signatures) where signers enter data, check boxes, and sign. DocuSeal converts your PDF into a fillable form by detecting existing field zones and converting them to interactive elements.
When You Need Fillable Forms
Contracts and NDAs: Send a contract template. Clients fill in names, dates, and sign. No email back-and-forth. No missing signatures.
Onboarding forms: HR collects employee info, tax info, and acceptance signatures in one step. Auditable. Compliant.
Consent documents: Nonprofits, medical practices, and schools collect consent with one-click signing.
Procurement workflows: POs, vendor agreements, and approval chains flow through multiple signers automatically.
DocuSeal vs. Adobe Acrobat Pro
Adobe Acrobat Pro ($20/month) is built for PDF editing and annotation, not signing workflows. It requires Acrobat Reader on the signer's device. DocuSeal is signing-first: signers use a web browser. No software download. No Acrobat license. Better for collecting signatures at scale.
DocuSeal vs. DocuSign
DocuSign dominates enterprise e-signature. It also dominates enterprise pricing: $400-500/month minimum, or $2.50-5.00 per envelope. For a nonprofit sending 1,000 forms per year, DocuSign costs 2,000-5,000 dollars. DocuSeal on Opsily: $20/month flat, unlimited documents. Same legally binding signatures. Fraction of the cost.
Self-Hosted vs. Opsily Managed
DocuSeal is MIT-licensed open-source. You can self-host for free. You manage servers, backups, and security patches. Opsily's managed option ($20-100/month) removes that burden: German servers, automatic backups, 24-hour security updates, priority support. Choose based on your team's infrastructure skills.
Hosting Starts at $20/Month
Self-hosted DocuSeal is free. Opsily managed hosting includes German servers, GDPR compliance, automatic backups, and priority support.

Frequently Asked Questions
Everything you need to know about PDF forms, DocuSeal, and signing workflows.
A fillable PDF has interactive form fields (text boxes, checkboxes, signatures) where signers enter data. An editable PDF lets you modify text anywhere like a Word document. DocuSeal creates fillable PDFs optimized for collecting signatures and structured data. Fillable forms enforce field structure—signers can't accidentally delete important text. Editable PDFs offer flexibility but lose data control.
