MOV is Apple's QuickTime container — the native format for iPhone screen recordings, macOS screen captures, and ProRes-encoded footage. Convert to MOV when your destination is Final Cut Pro, iMovie, or Apple's Motion — these programs handle MOV without transcoding. For distribution, always use MP4 instead.
Same footage, different container. Get a file that plays where you need it to, with sensible defaults for codec, bitrate, and framerate.
Free-tier uploads are capped at 10 MB — fine for short clips and screen recordings, tight for anything long-form. Pro handles files up to 1 GB and batch jobs of up to 20 videos. Because video work is compute-heavy, sign-in is required on the free plan for anything past a minute of source video.
The defaults for MOV are set to the most-compatible codec for that container (H.264 for MP4, VP9 for WebM, and so on). If you want a smaller file at the same quality, pick a modern codec like H.265 — but check where the video's going first, because older devices can't play H.265.
Video conversion takes proportionally longer than audio or image work — roughly a few seconds per second of source video on a typical 1080p clip. The output downloads immediately once ready, and both the source and result are deleted from our servers within 30 minutes.
A file called MKV tells you almost nothing about what's inside — the container is a box that could hold several different codecs. The codec is what actually determines quality, size, and compatibility. Converting MKV to MOV usually means picking a new codec too; the defaults above are what most people expect to work everywhere.
Six scenarios where the format swap is the actual job — not incidental to something else.
Recent iPhones save videos as MOV wrapped around H.265, which older Windows machines and many web apps can't decode. Converting to a widely-supported MOV makes the clip playable everywhere.
HTML5 <video> reliably plays MP4 across every mainstream browser. Some formats (MOV, MKV, unusual containers) trigger downloads instead of playing inline. Converting to MOV first avoids the "why isn't this playing" support thread.
Final Cut loves MOV/ProRes. Premiere handles most things but chokes on variable-framerate phone MP4s. DaVinci Resolve wants specific codec support. Converting to what your editor actually understands prevents hours of debugging "why is playback laggy".
Email caps attachments at 25 MB. Slack's free plan tops out at 1 GB. Form portals often insist on under 100 MB. A modern codec-swap (H.264 → H.265) typically cuts size 40-60% at the same quality — usually enough to fit the limit without touching resolution.
Old AVI files, ancient FLV downloads, MPEG-2 rips from a decade ago — legacy formats work but eat disk space. Converting to a modern MOV halves storage without losing quality, and future-proofs the collection against the day players stop shipping with legacy decoders.
YouTube, Instagram, TikTok, and LinkedIn all publish their own "recommended encoding" specs. Converting to a spec-matching MOV before upload skips the platform's own re-encode and produces cleaner playback quality.
Technical comparison of the two formats — useful for deciding which to use, or for confirming what changes during conversion.

MKV (Matroska Video) is an open-source multimedia container format created in 2002 by the Matroska project. Named after the Russian matryoshka nesting dolls, MKV is designed to hold virtually unlimited numbers of video, audio, and subtitle tracks within a single file. It can encapsulate almost any video and audio codec, making it one of the most flexible container formats available today.
MKV is the preferred format for high-quality video archiving, HD and 4K content, and media libraries that require multiple audio languages or subtitle options. Its open-source nature and codec-agnostic design mean it can adapt to new compression technologies without format changes. The main drawback is compatibility — MKV is not natively supported by all devices, particularly older smart TVs, gaming consoles, and some mobile players. For broad distribution MP4 remains more universally playable, but for personal libraries and archival purposes MKV is often the superior choice.
