HDR data will be tone-mapped

Your MP4 file may contain HDR (High Dynamic Range) data. JPG only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.

Generation loss — quality may degrade

MP4 uses lossy compression, and so does JPG. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.

Some metadata may not survive

Your MP4 file may contain MP4 atoms, chapter markers metadata. JPG has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

Color depth reduction: 265-bit → 24-bit

MP4 stores up to 265 bits per channel, but JPG supports only 24 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.

What compression artifacts to expect

JPG lossy compression can produce blockiness and mosquito noise around sharp edges. 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.

  • You're creating a podcast or audio file from video content
  • You need a file that works in web browsers
  • You need maximum device and software compatibility

When NOT to Convert

  • You're converting just because the file "seems old" — re-encoding lossy-to-lossy always degrades quality
