Frequently Asked Questions

Why do PNG files only have black backgrounds inside the OneDrive folder?

This is caused by a known rendering conflict between Windows 11 File Explorer and OneDrive's thumbnail caching system. The transparent layer of the PNG is incorrectly interpreted and filled with a black color during the cloud-sync display process.

Will moving the PNG files out of OneDrive restore the transparent background?

Yes. If you copy or move the affected PNG files to a local folder not synced by OneDrive, such as your local Documents or Desktop, the thumbnails will generate correctly with their original transparent backgrounds.

Is my actual image file corrupted by this OneDrive issue?

No, your files are perfectly safe. The black background is purely a visual glitch in the thumbnail preview generated by Windows 11. The actual image data remains fully intact and transparent when opened in a dedicated photo viewer or editing software.
