✅ USE CASES

Handling multiple PDF forms, signatures, and company seals can take up valuable time. Una PDF Editor makes this process faster with AI-powered document editing. It can analyse multi-page PDFs, detect fillable fields, and automatically add text, dates, tick marks, signatures, and company seals. Users can review and adjust everything before downloading their files. The platform also offers access controls, so only approved staff can use the organisation’s seal. Another useful feature is its two-file download system, which provides an editable copy and a permanently signed version. It is a practical solution for organisations looking to reduce paperwork and simplify document management.

💡 Notable Features

What sets Una apart?

🤖 AI-Powered PDF Auto-Fill

Una PDF Editor uses AI to analyse entire PDF documents and detect fields that need information. It can automatically add text, dates, tick marks, signatures, and company seals. Users do not need to fill every field manually. They can review the results, make changes, and confirm everything before downloading.

🔏 Company Seal Access Control

Managing company seals requires care, especially when multiple employees handle official documents. Una PDF Editor allows administrators to decide who can access the seal feature. They can grant or revoke permissions for individual staff members. Unauthorised users cannot see the seal button, helping organisations maintain better control over document approvals.

📑 Multi-Page PDF Support

Working with lengthy documents can be time-consuming, particularly when several pages need editing. Una PDF Editor can analyse multiple PDF pages simultaneously and identify fields across the entire document. It also supports mixed Chinese and English layouts. This makes it easier for teams to handle complex forms without checking every page manually.

📥 Two PDF Output Modes

Una PDF Editor makes document management easier by generating two versions of a completed PDF. The first is an editable copy that allows further changes. The second contains permanently embedded signatures and company seals. Both files are downloaded together, giving teams a convenient way to keep working drafts and final documents organised.

🔐 Microsoft 365 Single Sign-On

Getting started is easier with Microsoft 365 Single Sign-On (SSO). Staff can use their existing Microsoft 365 login instead of creating another password for the platform. This makes access more convenient for organisations that already use Microsoft’s services. It also helps simplify the login process for teams handling documents regularly.

✍️ Manual Review and Editing

AI automation is helpful, but important business documents still need human attention. Una PDF Editor allows staff to review automatically filled information and make adjustments before downloading the final files. Users can also add items manually when needed. This balance between automation and human review helps improve accuracy and gives teams more control.

👨‍🎓 Expert's Opinion

what does our expert say about Una?
Una PDF Editor is a practical tool for organisations that deal with large amounts of paperwork. Its AI auto-fill feature is especially useful because it can detect fields across multiple PDF pages and fill them in quickly. I also like the seal access controls, which give administrators better control over document approvals. The option to download both editable and signed copies is another helpful addition. However, the tool may be more useful for businesses than individuals who only need basic PDF editing. Its custom-built approach may also require a demo and some initial setup. Overall, it is a promising solution for reducing repetitive paperwork.
