Frequently Asked Questions
Is MixConvert safe to use?
Yes, it is one of the safest converters available. Because it operates client-side, your files are processed locally on your computer or phone. We do not have access to your files, and they are never stored on our servers.
Do I need to install any software?
No installation is required. MixConvert works directly in your web browser (Chrome, Firefox, Safari, Edge). However, you can choose to "Install" it as an app for easier access if you wish.
What is the maximum file size?
Since conversions happen on your device, the limit depends on your available RAM and processing power. Most modern devices can easily handle files up to 2GB. For very large video files, ensure you have other tabs closed for best performance.
Can I convert files on my phone?
Absolutely. MixConvert is fully responsive and optimized for iOS and Android devices. You can convert HEIC photos from your iPhone to JPG, or compress videos directly on your Android phone.
Why did my conversion fail?
Conversion failures can happen if a file is corrupted, password-protected, or if your browser runs out of memory. Try closing other tabs or converting fewer files at once. If the issue persists, the specific format variant might not be supported yet.
