Open-sourcing Image Converter for Android

Last update: 2025.11.14

Original post 2025.11.03

I built Image Converter during a hackathon in a short amount of time and published it in November 2020. Since it did not generate any revenue (no subscriptions sold, totaling $22.50 from ads over five years), I largely forgot about it. However, Google reminded me that I should update it to target the latest SDK, or else face consequences. Additionally, I decided to move it as the final project from self-hosted SVN to GitHub, five years after its initial launch. As a result, I have decided to open-source it as well, marking the ninth Android app that I have open-sourced!

Please note that the published version still targets Android SDK 30 and will not work on newer Android devices, as it uses direct storage access, which was once allowed. I haven't updated it yet, as it is not a priority for me. Meanwhile, users with slightly older Android devices can still enjoy the free, open-source, and lightweight image converter. Just follow the link below:

Update 2025.11.14

Sooner than originally planned, I have updated Image Converter to target Android SDK 35. To make my life easier, I have decided to drop support for older devices, so the latest release requires a minimum Android SDK of 29. The version for older devices will remain downloadable here: Image Converter release 1.0.6.

The app has also been visually updated to support Material Design 3 with Dynamic colors.

Another personal milestone has been reached: the first app that has been built on Linux instead of on a Windows system.
