Batch Settings
Quality reduction ahead
AIFF is uncompressed, meaning every bit of data is preserved. FLV uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Some metadata may not survive
Your AIFF file may contain ID3v2, AIFF chunks metadata. FLV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
FLV lossy compression can produce blockiness, banding. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
About AIFF to FLV Conversion
Short answer: yes, you can convert AIFF to FLV online for free, and quality is well preserved with the right settings. Just upload your .aiff file to CocoConvert, pick FLV as the output, and click Convert. The whole process takes seconds.
Now for the details. AIFF is Apple's uncompressed audio format — equivalent to WAV in quality. FLV (Flash Video) is a legacy streaming format — converting to MP4 is recommended for modern use. Converting between these two formats lets you reduce file size without visible quality loss.
Full Name: AIFF uses Audio Interchange File Format, while FLV uses Flash Video. Compression: AIFF uses None (uncompressed), while FLV uses Lossy. Color Depth: AIFF uses —, while FLV uses 8-bit.
Your AIFF file is decoded and re-encoded as FLV. FLV lossy compression can produce blockiness, banding. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
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.
