FLV TO WEBM GUIDE

Why Convert FLV to WEBM?

Convert FLV video to WebM for playback, editing, sharing or compatibility with another media workflow.

Recommended starting pointKeep the original FLV file until you confirm the WebM result works correctly in your target software or device.
INPUT

FLV

A legacy Flash Video container still encountered in older archives, applications and publishing systems.

Legacy Flash-oriented workflows that explicitly require FLV.
OUTPUT

WEBM

An open media container designed for efficient browser and web delivery, commonly paired with VP9 or AV1 video.

Modern web playback and browser-focused delivery.

How to convert FLV to WEBM

  1. Upload your FLV file above.
  2. Keep WEBM selected as the output.
  3. Choose Balanced quality unless your workflow needs another setting.
  4. Open Advanced settings only if you need trimming, resolution, bitrate, sample rate or a custom filename.
  5. Start the conversion and download the finished file when it is ready.
Before you convert

Modern browsers and devices generally prefer MP4 or WebM. Compatibility outside browsers can vary more than with MP4.

Changing a container or codec cannot recreate quality already missing from the source, so keep an important original when possible.
