Quality reduction ahead
PNG is lossless, meaning every bit of data is preserved. MP4 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 PNG file may contain tEXt, iTXt, ICC metadata. MP4 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
MP4 lossy compression can produce blockiness, banding in gradients, mosquito noise. 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.
