MOV vs 3GP — Comparison & Free Converter
Fast, instant MOV to 3GP conversion. No signup required. Just drop your .mov file and get .3gp in seconds.
Batch Settings
HDR data will be tone-mapped
Your MOV file may contain HDR (High Dynamic Range) data. 3GP 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
MOV uses lossy compression, and so does 3GP. 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 MOV file may contain QuickTime atoms, chapter markers metadata. 3GP 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: 10-bit → 8-bit
MOV stores up to 10 bits per channel, but 3GP supports only 8 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
Default format on iPhone
Your device saves files in MOV by default (iPhone, iPad, Mac cameras). Most people convert because the files won't open on other devices — 3GP is universally supported and will work everywhere.
What compression artifacts to expect
3GP lossy compression can produce heavy blockiness (extreme compression). 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.

What Happens When You Convert MOV to 3GP
Your MOV video is transcoded — video and audio streams are decoded and re-encoded into the 3GP container. This is a lossy process that takes time proportional to the video duration.
Your MOV file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with 3GP-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the 3GP container and the file is saved

Frequently Asked Questions
Should I use MOV or 3GP?
It depends on your goal. MOV offers smaller files via lossy compression. 3GP offers smaller files via lossy compression. Choose based on whether file size or quality matters more for your use case.
Is 3GP higher quality than MOV?
Not necessarily. Your MOV file may contain HDR (High Dynamic Range) data. 3GP 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. Quality depends on the compression type and settings, not just the format name.
