I created this tool that generates mock files (videos, images, audio, various documents) directly in your browser without uploading anything to a server. Perfect for developers who need test files but don't want to upload real data. Everything happens client-side using Canvas API and FFmpeg.wasm. You can generate files with exact sizes, which is super handy for testing upload limits or storage quotas. No registration required, just pick your format and size. Curious what other file types would be useful for your testing workflows.   submitted by   /u/humast [link]   [comments]
