Pufomi (formerly Puffin Tools)
Pufomi runs free browser productivity tools that convert, compress, and resize images without sending files to a server. Drop a photo on the page and WebAssembly handles the work on your device, so nothing uploads and nothing gets stored in the cloud. The live Image Tools suite covers format swaps, HEIC conversions, and compression for JPG, PNG, WebP, GIF, SVG, AVIF, and HEIC files.
Most online converters upload your files to a remote server before they return a download link. Pufomi keeps every byte on your drive, which means you can use it offline after the page loads and you avoid artificial upload caps. Batch mode processes multiple images in parallel, and the site states modern browsers handle files up to about 50 MB depending on available memory.
The site fits photographers cleaning up iPhone HEIC shots, web developers chasing PageSpeed WebP wins, and office workers shrinking screenshots for email. PDF and spreadsheet utilities are labeled Coming Soon, so today the product is image-first rather than a full document workstation.
