Convert to MP4 online
Start with the exact MP4 converter you need
If your goal is MP4 output, use a focused converter page instead of starting from the generic video hub. These routes preselect common MOV, MKV, WebM, AVI, HEVC, AV1, and ProRes to MP4 workflows.
MP4 with H264 video and AAC audio is usually the safest choice for phones, browsers, smart TVs, messaging apps, social uploads, and older media players.

Why convert video online?
Online video converter for MP4, MOV, AVI, WebM and MKV
Upload a video, choose the output format, then convert it online for free. This video converter supports MP4, MOV, AVI, WebM, MKV, WMV, FLV, M4V, MPEG and 3GP for playback, sharing and editing workflows.
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.
For a specific result, open WEBM to MP4 or MOV to MP4, create Video to GIF Maker clips, trim with Video Trimmer, merge with Video Merger, change video speed with Video Speed Changer, extract still images with video frame extractor, reduce file size with Video Compressor, or save the audio with Extract Audio From Video or MP4 to MP3.
When a modern codec will not play on an older phone, browser, TV, or editor, use the AV1 to H264 converter or H265 to H264 converter to create a more widely supported H264 MP4.
Large video files are supported up to the site upload limit of 1 GB, so you can convert full-resolution MP4, MOV, AVI, WebM, and MKV files without lowering the source quality before upload.
For Apple ProRes exports from Final Cut Pro, Premiere Pro, or DaVinci Resolve, use the English ProRes to MP4 converter to turn a large ProRes MOV master into a smaller H264 MP4 delivery file.
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.
