Hey Product Hunt 👋

While working on Ashampoo Photo Organizer (at my past job), I ran into a recurring issue: generating thumbnails during image import of my test photo set was taking a lot of time.

That made me think more about the problem space. Many images already contain embedded thumbnails, so why not use them when they are good enough? Some apps, like the Samsung Camera app on Samsung devices, include surprisingly high-quality embedded thumbnails (512 × 384 px or better) that can be reused to speed things up. Others, like iPhones or many DSLR cameras, often embed only very small thumbnails (160 × 120 px) that are not very useful for display.

Working on this problem taught me how much performance you can gain by reusing embedded thumbnails instead of always generating new ones. I noticed that tools like Mylio and ACDSee seem to take a similar approach as they imported my optimized photos much faster as well.

I tried solving this using command line tools like ExifTool to batch generate and embed thumbnails, but the workflow felt tedious and the results were not what I wanted. Existing tools also felt either too complex or not really focused on this specific task.

So I built a simple drag and drop tool that quickly optimizes thumbnails.

Under the hood it uses libvips for fast generation of high quality thumbnails.

I hope you like it. 🙂
