ConvertSafe
Convert files 100% privately in browser. Nothing uploaded
ConvertSafe launched on April 7, 2026.
What it does
A free file converter that runs 100% in your browser. No uploads, no servers, no accounts. Your files never leave your device. 50+ format pairs across images (JPG, PNG, WebP, HEIC, AVIF, SVG, TIFF, ICO), data (CSV, JSON, XML, YAML, XLSX), and documents (PDF, DOCX, Markdown, HTML, TXT). All conversions happen client-side using the Canvas API, WebAssembly, and JavaScript libraries. Verify the privacy claim yourself: open DevTools, check Network tab while converting any file. Zero outbound data
Convert files securely in your browser. No upload, no signup. Privacy-first conversion for images, documents, and data formats.
No uploads. No signups. No data collection. ConvertSafe converts images, documents, and data formats entirely on your device using JavaScript and WebAssembly. Pick a format pair below or browse all converters. Every conversion runs locally in your browser. Drag and drop or click to select. For text formats like CSV and JSON, you can paste data directly. Pick the target format. Conversion starts instantly in your browser with no server involved. Your converted file is ready. Download it or preview the output before saving. Most online converters upload your files to their servers. ConvertSafe is different. The conversion code runs on your device. We never see your data. Your files are…from convertsafe.app

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.
