日本国内の音声研究機関や大学では、NIST形式が国際的な標準として認識されており、研究成果の共有や相互運用性の確保において重要な役割を担っています。
About FLAC to NIST Conversion
Short answer: yes, you can convert FLAC to NIST online for free, and quality is well preserved with the right settings. Just upload your .flac file to CocoConvert, pick NIST as the output, and click Convert. The whole process takes seconds.
Now for the details. FLAC is lossless audio compression — bit-for-bit identical to the original at roughly 50-70% of WAV size. NIST is a widely used file format. Converting between these two formats lets you convert between formats quickly.
Your FLAC file is decoded and re-encoded as NIST. Converting FLAC to NIST maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

Frequently Asked Questions
Is FLAC to NIST conversion free?
Yes. CocoConvert offers free FLAC to NIST conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is FLAC to NIST conversion?
Most files convert in 2–10 seconds depending on size. Large audio files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded FLAC file and the converted NIST file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting FLAC to NIST lose quality?
Converting FLAC to NIST maintains high quality with CocoConvert's optimised encoder settings.
Can I convert NIST back to FLAC?
Yes, CocoConvert supports NIST to FLAC conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
