Sponsor File Viewer

File Viewer remains Apache-2.0 open source. Sponsorship helps fund rendering compatibility, documentation, examples, offline assets, and long-term maintenance.

GitHub Sponsors

Sponsor File Viewer through GitHub with a one-time or recurring contribution. The account belongs to @wybaby168, the primary maintainer of File Viewer.

WeChat and Alipay

Domestic supporters can use the WeChat / Alipay support page for a convenient one-time contribution.

Enterprise support

Sponsorship sustains open-source maintenance and does not include a service-level agreement unless a published sponsorship tier explicitly says otherwise. For private deployment, custom compatibility work, commercial evaluation, or committed response expectations, use the enterprise support channel.

Whether or not you sponsor, the open-source features and documentation remain available under the same license.
