A fast, privacy-first image converter that runs in browserOct 2025 · imageconverter.dev · ▲48
Hey HN I built ImageConverter.dev because I got tired of “free” image converter sites that force uploads, or throttle conversions.

I built a frontpage for personal blogs▲783
With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
