Compress ppt free online▲6
Hi HN I built a simple online PowerPoint compressor that runs entirely in the browser: https://www.pptcompressor.online/ No server uploads. No login. No installation. It works by unpacking `.pptx` files, recompressing embedded images with Canvas/WebP, and zipping them back — all using JavaScript and Web APIs. Great for reducing file sizes before sending slides by email or uploading to platforms with size limits. Built with: - JSZip - Canvas API - Web Workers - Pure HTML/CSS/JS (no backend) I’d love feedback on speed, compatibility, and ideas for new features…

Smallimg▲7
Hi HN, I built a free image compression tool called Smallimg.cc that runs entirely in the browser. The main motivation was privacy. I was never comfortable uploading potentially sensitive images to a third-party server just for compression. This tool solves that by using JavaScript and WebAssembly to perform all the processing on the client-side. Your files are never transferred over the network. Key features: Total Privacy: Your images never leave your computer. Incredible Speed: No upload/download time, just instant processing. Full Control: You can adjust quality, resize, and convert…
