How Browser-Based Conversion Works
Traditional converters upload your files to remote servers. BlinkConvert is different—everything happens locally on your device.
Select Your Files
Drag and drop or click to select audio or video files from your device. Support for MP4, MP3, WAV, MOV, WebM, FLAC, and many more formats.
Local Processing
FFmpeg runs directly in your browser using WebAssembly technology. Your files are processed using your device's CPU—no server required.
Download Result
Once conversion is complete, download your converted file directly. The original and converted files only exist on your device.
Why Client-Side Processing is More Secure
When you use traditional online converters, your files are uploaded to unknown servers where they could be stored, analyzed, or accessed by third parties. BlinkConvert eliminates these risks entirely by keeping everything on your device.
Files Stay on Your Device
Your media files are never uploaded anywhere. They remain on your local storage throughout the entire process.
No Server-Side Storage
Unlike cloud converters, we have no servers storing your data. There's nothing to hack or leak.
Zero Data Collection
We don't collect personal information, track your usage, or use analytics cookies.

Frequently Asked Questions
Everything you need to know about BlinkConvert and browser-based media conversion.
How does browser-based conversion work?
BlinkConvert uses FFmpeg compiled to WebAssembly, which runs directly in your web browser. When you select a file, it's processed entirely on your device using your computer's processing power. The file never leaves your device or gets uploaded to any server.
Is my data safe with BlinkConvert?
Absolutely. Since all processing happens locally in your browser, your files never touch our servers. We don't collect, store, or have access to any of your files. This makes BlinkConvert one of the most private conversion tools available.
What file formats are supported?
BlinkConvert supports a wide range of audio and video formats including MP4, MP3, WAV, MOV, WebM, FLAC, AAC, OGG, M4A, AVI, MKV, and more. You can convert between most common media formats.
Is there a file size limit?
There's no hard limit imposed by us, but very large files may be slower to process depending on your device's capabilities. Most files under 500MB convert quickly. For very large files, ensure you have sufficient RAM available.

Yes! After the first visit, BlinkConvert can work offline. The FFmpeg library is cached in your browser, allowing you to convert files even without an internet connection.
