🔧 Thumbnail Fixer 🔧

This tool is designed to repair and enhance embedded thumbnails in images.

Use case

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).

Performance

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.

Screenshots

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.

Installation

Self-signed warning

Windows will warn you about the self-signed certificate. As this is a free, open-source project, investing in a costly code signing certificate isn't practical.

To continue, click "More info" and then "Run anyway".

Used tech

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.
