About the MP4 Name Changer
The MP4 Name Changer is a focused, lightweight tool designed specifically for renaming MP4 video files. MP4 is the most common video format — used by smartphones, action cameras, screen recorders, and video editors. This tool gives those files clean, meaningful names in seconds.
The interface is stripped down to the essentials: upload MP4s, type a name, download. No unnecessary options, no clutter. It's optimised for mobile use — tap to select videos from your camera roll, type a name, and you're done.
Why a Dedicated MP4 Tool?
MP4 accounts for the vast majority of video files people work with daily. Having a focused tool means a simpler interface, faster workflow, and zero confusion. If you need to rename other video formats (AVI, MOV, MKV), use our Video Rename Online tool instead.
Mobile Optimised
Designed with touch in mind. Large tap targets, clear labels, and a streamlined workflow. Rename phone videos before sharing them on WhatsApp, uploading to YouTube, or backing up to Google Drive — all from your mobile browser.

Frequently Asked Questions
Can I only rename MP4 files?
Yes, this tool accepts only .mp4 files. For other video formats (AVI, MOV, MKV), use our Video Rename Online tool or Batch File Renamer.

Does it work on my phone?
Yes! This tool is specifically optimised for mobile devices. It works on iPhone Safari, Android Chrome, and all modern mobile browsers.
Are my videos uploaded anywhere?
Absolutely not. Everything runs inside your browser. Videos are read, renamed and zipped on your device.
Is there a file size limit?
Individual MP4 files can be up to 100MB each. There is no limit on the number of files.
Can I set a custom start number?
Yes. Change the "Start Number" field to continue numbering from a previous batch — e.g. start from 11 if you already have 1-10.
