mm:ss or seconds. Trimming only the end stays lossless; moving the start forces a re-encode.
Downscaling re-encodes the video and costs some quality.

How to Use
Drag or click to load a .mov video. The file never leaves your browser.
The video and audio codecs are read first to tell you whether the conversion is lossless. Phone recordings almost always are.
The original stream is copied into a new MP4 container. Download it as soon as it finishes.
FAQ
Is the quality really untouched?
Yes. The video data is copied, not recomputed — a remux, not a transcode — so the output is bit-for-bit identical in picture quality to the source.
Can I trim or resize as well?
Advanced options cover trimming (start/end), downscaling, rotation, and audio removal. Rotation, end-only trimming, and audio removal copy the original stream untouched, so they stay lossless; downscaling and moving the start point require the video to be re-encoded, costing some quality and time. A badge tells you which case you are in before you convert.
Can I just rename the file to .mp4?
Not reliably. It sometimes plays, but the internal structure still differs from the MP4 spec, so editors and upload validators often reject it. This tool rewrites the structure as a proper MP4.
Which MOV files are supported?
Phone recordings and screen captures (H.264/HEVC video + AAC audio) convert losslessly almost every time. Production codecs such as ProRes or uncompressed PCM audio can also be copied across, but the resulting MP4 may not open in ordinary players — you are warned before converting.
What about ProRes footage?
The data is copied untouched, so the conversion itself is lossless. But a ProRes-in-MP4 file often will not play outside editing software. If your goal is normal playback or an upload form, re-encoding to H.264 with a desktop app is the better fit.
What about large files?
The input is read in pieces, so large files are fine to read. The finished MP4 is held in memory until you download it, so multi-gigabyte files can fail on low-memory devices.
Is metadata such as the capture date preserved?
Yes, the metadata tags from the source are carried over. Keep that in mind if the video contains location data and you are sharing it externally.
Is my video uploaded anywhere?
No. Everything runs in the browser. Open dev tools (F12), watch the Network tab, and load a file to see for yourself.
