ABC Header
ABC Header gives HumHub spaces and user profiles professional, update-safe header control. Customize responsive banner proportions, choose circle or square logos, preserve transparent images, support AVIF/WebP/JPG/PNG optimization, and bulk-convert existing banners and logos to the smallest suitable file size without modifying HumHub core files.
ABC Header is a professional HumHub module for customizing space and user profile headers without changing HumHub core code. It replaces fragile core hacks with a clean module-based solution, so header behavior remains easier to maintain across HumHub updates.
With ABC Header, administrators can control how profile and space banners appear across desktop, tablet, and mobile layouts. Banner proportions are handled responsively, so header images keep their intended visual ratio instead of being forced into HumHub’s default narrow banner height.
The module also gives much better control over profile images and space logos. Depending on the design need, logos can be displayed as a circle, rounded square, or sharp square. This is especially useful for organizations, schools, companies, churches, shops, and directory spaces where square logos often look better than cropped circular images.
ABC Header also improves image quality and performance. It supports modern image formats and can automatically compare AVIF, WebP, JPG, and PNG versions of a banner or logo, then keep the smallest suitable file. Transparent logos are handled properly, so PNG/WebP/AVIF files with transparency no longer show unwanted black backgrounds.
For existing installations, admins can run a bulk conversion process for all current header banners and profile/logo images. Before conversion, an admin-only backup download option helps protect original files. There is also an optional guarded setting to delete original files after conversion, with a clear backup warning.

- Responsive custom header banner proportions
