VidCompress / MOV compression
MOV files from iPhone and Mac are large. Compress them directly in your browser and get a sharing-ready MP4 out.
Or jump straight to a destination:
MOV is the format your iPhone and Mac record in, and it is notoriously large — a minute of 4K footage can run hundreds of megabytes. That makes MOV files awkward to email, message, or upload. Compressing them solves both the size and the compatibility problem in one step.
VidCompress takes your MOV, compresses it to a target size, and outputs an MP4 — which is smaller, plays on every device, and uploads cleanly to platforms that choke on MOV. Files under 300 MB are handled locally in your browser, so personal recordings stay private.
Quick reference
Pick a target
Choose where the video is going — Email, Discord, WhatsApp, Telegram, or a custom size — and the preset sets the encoding for you.
Add the MOV
Drag in the MOV straight from your iPhone export or Mac. There is no need to convert it first.
Compress and convert
VidCompress reduces the size and converts to MP4 in the same pass, keeping resolution as high as the budget allows.
Download the MP4
Save the result. The MP4 is smaller than the MOV and far more widely compatible.
How do I compress a MOV file from my iPhone?
Export or AirDrop the MOV to this page, pick a target size, and VidCompress compresses it and converts it to a smaller MP4 in one step.
Why are iPhone MOV files so large?
iPhones record at high resolution and high bitrate (often 4K HEVC), which produces large files. Compressing brings them down to a shareable size.
Does it convert MOV to MP4?
Yes. The output is MP4, which is smaller and compatible with platforms and apps that do not accept MOV.
Do I need to install anything?
No. MOV compression runs in your browser. Files under 300 MB never leave your device.
Is it free?
Yes. The free plan compresses up to 300 MB locally with no signup or watermark.
