Vira

Automatically prepare WebM, MOV and incompatible MP4 for WhatsApp Web. Local conversion, without uploading your videos.

Your video. In the right format. Vira automatically prepares WebM, MOV and incompatible MP4 videos when you select attachments in WhatsApp Web. Convert directly in your browser instead of opening a separate converter, downloading a result and attaching it again. HOW IT WORKS 1. Open WhatsApp Web in Chrome. 2. Choose one or more videos using the attachment picker. 3. Vira prepares compatible MP4 files and opens the attachments in the WhatsApp preview. 4. Review your attachments and send them yourself. Vira never sends messages automatically. STAY IN CONTROL • Convert multiple selected videos in a batch. • Follow conversion progress and cancel when needed. • Close the popup while conversion continues. • Turn automatic conversion on or off. • Compatible MP4 files are left unchanged. If an item cannot be converted, Vira reports the error and passes that original file back to WhatsApp; WhatsApp may still reject it. LOCAL VIDEO PROCESSING Video conversion happens on your device. Your videos are not uploaded to Vira or to remote conversion servers. Temporary files may use browser memory and private browser storage during processing. OPTIONAL FEEDBACK Suggest a format or report a problem from the extension. You review and confirm each submission before it is sent through Formspree. Feedback does not automatically include videos, chat messages or contacts. No account is required, and Vira has no automatic usage telemetry. SUPPORTED WORKFLOW Chrome 155 or later on desktop, with WhatsApp Web. Supports WebM, MOV and incompatible MP4 subject to the codecs available in your browser and the contents of the file. Conversion starts through the attachment picker; drag-and-drop and clipboard attachments are not part of this release. Additional formats are not included simply by requesting them. The extension interface supports English and Portuguese. The current release is free. Support: muriel.developer@gmail.com Vira is an independent extension and is not affiliated with WhatsApp or Meta.
