This tool is designed to repair and enhance embedded thumbnails in images.
Embedded thumbnails improve the performance of applications like Windows Explorer, Apple Finder, Ashampoo Photo Organizer, Mylio, ACDSee, and many more.
Contemporary tools such as Ashampoo Photo Organizer may even opt not to generate their own thumbnails if the embedded ones are of sufficient quality, thereby saving computing power.
To meet Ashampoo Photo Organizer's requirements, ensure that thumbnails are at least 480 x 360 pixels (which is the tools default).
On a Core i7-9700K, processing a set of 18,000 test photos using a single core (~25% CPU utilization) took approximately 21 minutes. RAM usage averaged 1 GB, with a peak of 2 GB. The data was read from and written to an internal M.2 SSD.
Currently, on Windows, the app appears different due to a bug in Compose Multiplatform that prevents undecorated windows from displaying correctly. Once the issue is resolved, the undecorated design will be restored.
For Windows, it is recommended to use the version available in the Microsoft Store as this version is properly signed.
If you prefer to avoid the Microsoft Store, you can download a self-signed installer here.

The app is built using Kotlin with Compose Multiplatform.
Key libraries utilized in this project include libvips (via vips-ffm) for efficient thumbnail creation and Ashampoo Kim for convenient metadata handling.
- JetBrains for making Kotlin.
- John Cupitt for making libvips.
- carrot for making vips-ffm.
- Mike Hearn for making Hydraulic Conveyor
- Yahor for making the Valkyrie IDEA plugin.
