Why convert video online?
Convert video files online for playback, sharing, or editing
Use this online video converter when you need a file that opens everywhere. Upload MP4, MOV, AVI, WebM, MKV, WMV, FLV, M4V, MPEG, or 3GP, then convert to the format that fits your phone, browser, smart TV, social platform, or editing workflow.
Convertr runs entirely in your browser, so there is nothing to install and no account to create. You can change the output container, re-encode the video codec, lower the bitrate to reduce file size, or pick a new resolution before you download the finished file.
Most users convert videos online to make files compatible with iPhone and Android playback, prepare uploads for WhatsApp or social media, turn WebM and MKV into MP4, or re-encode AV1, HEVC, and VP9 into H264 for wider support.
Best for compatibility
Convert to MP4 with H264 video when you need the safest format for phones, browsers, TVs, and messaging apps.
Best for smaller files
Lower the resolution or bitrate to shrink large videos before sharing them by email, chat, or cloud storage.
Best for editing apps
Convert MOV, WebM, MKV, and legacy camera files into formats accepted by common editors and desktop tools.
Best for codec problems
Re-encode AV1, H265/HEVC, or VP9 when the original file will not play smoothly on older devices or software.
Popular online video converter workflows
These are the common tasks users expect from a generic video converter page: fast container swaps, MP4 exports, and compatibility-focused re-encoding.

Supported video formats and best output choices
A generic video converter page needs to explain both format coverage and when to choose MP4, MOV, WebM, AVI, or MKV.
Formats you can upload or export
You can also use advanced settings to switch codecs, reduce file size, or prepare a more compatible export for older hardware and apps.
Which video format should you choose?
MP4: best default for playback, sharing, and social uploads. Choose MP4 when you want the widest support.
MOV: useful for Apple workflows and some editing tools, especially when you need to stay close to camera or QuickTime exports.
WebM: useful for browser delivery and lightweight web video, but often converted to MP4 for broader compatibility.
AVI or MKV: useful as source files, archives, or legacy downloads, but commonly converted before sharing on modern devices.
Popular Video Conversions
