Frequently Asked Questions

General

What is MediaConvertKit?
MediaConvertKit is a free, browser-based file conversion platform. It provides tools to convert video to MP3, convert images, manipulate PDFs, and process audio — all running entirely in your web browser without uploading any files to a server.
Is MediaConvertKit free to use?
Yes, all tools on MediaConvertKit are completely free. No subscription, no credits, no payment, no registration required.
Do I need to create an account?
No. MediaConvertKit requires no account or registration. Just use any tool directly from the website.

Privacy & Security

Are my files uploaded to a server?
No. Your files never leave your device. All conversion processing uses WebAssembly and JavaScript running in your browser tab. We have no technical ability to receive or store your files.
Can MediaConvertKit access my files?
No. Because your files are never transmitted to our servers, we cannot access them. The File API only gives the browser tab access to your file — not our servers.
What data does MediaConvertKit collect?
We do not collect file data, file names, or conversion results. We may collect standard web analytics (page views, browser type) but this never includes file content.

Video to MP3

What video formats does the Video to MP3 converter support?
Supported formats include MP4, MOV, MKV, AVI, WebM, FLV, WMV, 3GP, M4V, and MPEG.
What MP3 quality options are available?
128 kbps (good for speech), 192 kbps (recommended for music), 256 kbps (high quality), and 320 kbps (maximum quality).
How long does video to MP3 conversion take?
A typical 3-minute MP4 converts in about 5–20 seconds depending on your device speed and video resolution. The first conversion after visiting the page takes longer because FFmpeg.wasm needs to load.

Browser & Compatibility

Which browsers are supported?
Chrome 90+, Firefox 89+, Edge 90+, and Safari 15+ are all supported. Chrome generally offers the best performance for WebAssembly-based conversions.
Does it work on mobile?
Yes, MediaConvertKit works on iPhone (Safari) and Android (Chrome). For files larger than 200 MB, a desktop browser is recommended due to mobile RAM limitations.
Why does the first conversion take longer?
FFmpeg.wasm (the conversion engine) must be downloaded from the CDN the first time you use a video or audio tool. This is approximately 8–12 MB and is cached by your browser for subsequent uses.
