Why ColabSave?
Every tool runs entirely in your browser. Your files are processed on your own device — never uploaded to a server. This is fundamentally different from most online converters, which require you to upload your files for processing.
The Privacy Advantage
When you use a server-based converter, your photos and videos are transmitted over the internet, stored on someone else's computer, processed there, and sent back. You have no way to know if copies are kept, who has access, or how long they're retained.
ColabSave uses WebAssembly and HTML5 Canvas APIs to process files directly in your browser:
- No privacy risk — your files stay on your device
- No upload time — processing starts instantly
- No server costs — which means the tool stays free
- Works offline — after the first page load
How Is ColabSave Free?
The tools are powered by your device's processing power, not our servers. This keeps our costs near zero. We display minimal ads to cover hosting and development. No subscriptions, no hidden fees, no premium tiers.
