How to compress MOV files
Upload your MOV file
Drag and drop a file or click to select one. Keep this page open while the file uploads and converts.
Compress the file
NexMedia re-encodes your MOV file on its own servers at the quality you choose. Processing time depends on the file size and how busy the queue is.
Download the compressed file
When the compression finishes, the download appears on this page. Your compressed file is kept for 2 hours, then deleted.
About MOV
Apple's QuickTime container, the format iPhones and Macs record in
MOV is Apple's QuickTime container, the default video format of iPhones and Mac screen recordings. It usually holds H.264 or HEVC video with AAC audio, and it shares its inner structure with MP4.
iPhone recordings lean on quality: 4K at 60 frames per second writes roughly 400 MB per minute, and even 1080p clips grow quickly because the default encoder favours compatibility over compression.
What compressing MOV does
Compressing a MOV re-encodes its video stream: the same footage moves into WebM's more efficient VP9 encoding, which spends far fewer bytes on an identical picture.
A one-minute 4K 60 fps iPhone clip weighs around 400 MB as a MOV; re-encoded to WebM at matched quality it commonly lands 30–50% smaller.
Settings you can change
Before you compress MOV, you can adjust: Video codec, Rate control, Quality (CRF), Video bitrate, Resolution, Width, Height, Scale fit, Frame rate, Encoder preset, Audio codec, Audio bitrate, Trim start, Trim duration, and Remove metadata.
Limits
Guests can compress files up to 100 megabytes and run 5 conversions per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your compressed MOV file is kept for 2 hours, then deleted.
Compressing MOV: questions and answers
Will compressing MOV reduce quality?
Re-encoding always discards a little detail, but keeping the original resolution and frame rate at a quality-matched bitrate leaves the difference practically invisible.
Can MOV files be compressed without any loss?
No — the H.264 or HEVC video inside a MOV is already lossy, so a re-encode cannot be mathematically lossless; it can, however, look the same at a fraction of the size.
Which settings can I change when compressing MOV?
You can adjust: Video codec, Rate control, Quality (CRF), Video bitrate, Resolution, Width, Height, Scale fit, Frame rate, Encoder preset, Audio codec, Audio bitrate, Trim start, Trim duration, and Remove metadata. the quality slider controls how many bits each frame keeps, and lowering the resolution is the biggest single lever on a phone clip's size
How much smaller will my MOV file get?
Expect iPhone and screen-recording MOVs to shrink by roughly a third, and more when the resolution is dropped alongside the codec.
How large a MOV file can I compress for free?
Guests can compress files up to 100 megabytes and run 5 conversions per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes. Your compressed file is kept for 2 hours, then deleted.
