I built XPRTIX (https://xprtix.com) because web tools shouldn't need to upload full media files to a remote server just to move a container header, shrink a video, or convert a HEIC photo.

XPRTIX runs these jobs directly in your browser. Files never leave your device.

Tools included in the suite: - Video: Fixes iOS video playback (relocates moov atoms and retags hev1 as hvc1 in-container without re-encoding), target-size compression (16MB WhatsApp, 10MB Discord, 25MB Email), format conversions, trimming, cropping, and MP3/GIF exports. - Image: Batch converts HEIC, WebP, AVIF, JPEG, and PNG. Handles resizing, cropping, compression, and EXIF location metadata stripping on save. - 3D: Inspects GLB, glTF, OBJ, STL, and PLY geometry, shows node weights, strips unseen geometry, and applies Draco or Meshopt compression locally. - SVG: Full-screen vector editor with node editing, boolean path operations, artboards, and clean React component code export.

Architecture: - Built with plain HTML, CSS, and ES modules (zero UI frameworks). - Uses native browser APIs and Mediabunny for fast local decoding. - Small WASM builds (FFmpeg, libheif, Draco, Meshopt) running inside Web Workers.

It is free to use, with no accounts and no watermarks: https://xprtix.com/

I'd value technical feedback on edge cases, broken files, or features you'd want added next.
