ImageConverterTool
Convert images in your browser
ImageConverterTool launched on April 8, 2026.
What it does
Most image converters work the same way: upload your file, wait for it to travel to a server, download the result. You have no idea what happens to your files in between. ImageConverter works differently. Everything runs locally in your browser using the Canvas API and WebAssembly. No upload. No server. No wondering. It's also faster. Conversion starts the moment you drop a file. No server queue, no waiting on bandwidth. Built by one developer. Free, no signup required.
Convert and compress JPG, PNG, WebP and HEIC images without uploading anything. Runs entirely in your browser — free, private, and instant.
I built this because I got tired of uploading photos to random converters and wondering what happened to them afterward. Everything runs locally — your files never leave your device. iPhone photos that won't open anywhere else. Converted instantly. Your files are processed entirely by your own browser. No server receives them, no database stores them. Open the network inspector while converting — zero upload requests. Because nothing is uploaded, conversion starts the moment you drop a file. No server queue, no waiting on bandwidth. A 5 MB image takes a second or two. The formats that cover most real use cases — including iPhone HEIC photos that most other tools handle badly or require an…from imageconvert.website

Hello HN, I've used a lot of image converter websites to run for my daily jobs, but they required uploading my assets on their servers which I didn't like. I decided to build it myself and publish as a website for everyone to use at no cost (since the conversion happened on your browsers) I'd live to hear your thoughts about it. Cheers,

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

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.
