Is my data safe and private during conversion?

Your privacy and data security are our top priorities: **Data Protection:** • Files are retained for at least 1 year (longer on paid plans); re-downloading extends retention • Encrypted connections (SSL/TLS) for all transfers • No permanent storage of your media files • GDPR compliant data handling • No file content analysis or monitoring **Privacy Options:** • Browser-only processing for sensitive files • No account required for basic conversions • Anonymous usage supported • No tracking of file contents or names **Security Measures:** • Malware scanning on all uploads • Secure server infrastructure • Regular security audits and updates • Isolated processing environments **Best Practices:** • We recommend browser-only processing for confidential files • Account users can view/delete their conversion history • No data sharing with third parties • Servers located in secure data centers with physical security For maximum privacy, use our browser-only mode which processes files entirely on your device without any server uploads.

Can I convert multiple files?

The converter processes one file at a time — pick your file, choose the output format and quality, convert, then queue the next one. Settings stay put between conversions, so working through a batch of files with the same target format is quick. If you need programmatic bulk conversion, our API is the better fit for large media libraries.

Does converting reduce quality?

We use lossless and high-bitrate settings by default. Converting between compressed formats can introduce small losses, so we recommend starting from the highest-quality source you have. Going from one lossy format to another (for example MP3 to AAC) re-encodes the audio and will always lose a little detail — convert from a lossless source such as WAV or FLAC when quality matters.

Are there limits on how long or how large a file can be?

Yes — each plan has a maximum per-job length and upload size: Free/Basic up to 30 minutes and 250 MB, Creator up to 2 hours and 500 MB, Pro up to 5 hours and 1 GB, and Studio up to 10 hours and 1 GB. Enterprise has no per-file limits. If a file is longer or larger than your plan allows, upgrade for a higher limit or split it into smaller parts. Pasting a link is limited by length only, not file size.
