Bulk File Converter — Free, Offline & No Upload Limits

Hey everyone,
Whenever I needed to bulk-convert images, documents, or media files, every top search result had the same catch: you have to upload your files to a random remote server, wait in a queue, and hit a paywall after 5–10 files. On top of that, you have no real idea what happens to your files once they hit their backend.

So I built a free bulk file converter that runs 100% locally on your own machine directly inside your browser.
How it works & privacy details:
Zero server uploads: All processing happens client-side on your CPU/RAM using browser APIs/WebAssembly. Your files never leave your device.
Works offline: Once the page loads, you can literally turn off your Wi-Fi / unplug your Ethernet and convert hundreds of files at once.
Verify it yourself: Open your browser's DevTools (F12 -> Network tab) while converting a batch you'll see zero outbound file requests.
No accounts, no file size caps, no daily limits: Since it uses your own hardware instead of my server bandwidth, I don't need to restrict batch sizes or force sign-ups.
Minimal monetization: There are no trackers, analytics scripts, or pop-ups just a single static 728x90 banner, I would appreciate if you disable adblockers.
Supported formats: PNG, JPG, WebP, GIF, BMP, TIFF, ICO, SVG, HEIC, AVIF, PDF, DOCX, DOC, TXT, Markdown, HTML, XLSX, XLS, ODS, CSV, TSV, JSON, XML, YAML, MP4, MOV, MKV, WebM, MP3, WAV, M4A, FLAC, OGG

I’d genuinely appreciate any feedback especially if you run into memory bottlenecks with massive batches or have suggestions for formats I should add next.
