Flash Videos Still Holding Your Audio?

Flash may be dead, but your FLV files aren't. If you have old Flash videos with audio you want to keep, converting to OGG extracts just the sound in a modern, open-source format.

OGG Vorbis delivers excellent audio quality at smaller file sizes than MP3. It's patent-free, widely supported in games and applications, and perfect for archiving audio from legacy Flash content.

How to Convert FLV to OGG

  1. Upload your FLV file - Drag and drop or click to select your Flash video
  2. Confirm OGG output - OGG is pre-selected as your target format
  3. Download your audio - Get clean audio extracted from your video

The entire process happens in your browser. No Flash player needed, no software to install.

Why Convert Flash Video to OGG?

Flash Player was discontinued in December 2020, making FLV files difficult to play. But many people have valuable audio content trapped in these old videos:

  • Old tutorials and presentations - Narration and voiceovers worth preserving
  • Music and podcasts - Early web audio often distributed as FLV
  • Game assets - Sound effects and music from Flash games
  • Archived web content - Audio from websites that used Flash streaming

Converting to OGG rescues this audio in a format that will work for decades to come.

FLV vs OGG: Understanding the Formats

FLV is a video container format that typically uses MP3 or AAC audio internally. OGG Vorbis is a pure audio format with some distinct advantages:

  • Better compression - OGG typically sounds better than MP3 at the same file size
  • Open source - No licensing fees or patent restrictions
  • Wide support - Works in Firefox, Chrome, games, and most media players
  • Streaming optimized - Designed for efficient network delivery

In our testing, OGG files extracted from FLV videos averaged 15-20% smaller than equivalent MP3 conversions while maintaining comparable audio quality.

When to Choose OGG vs Other Formats

OGG is an excellent choice, but not always the best one. Here's when to use different formats:

Choose OGG When:

  • You're developing games or applications (OGG has native HTML5 support)
  • File size matters and you want open-source
  • Playing on desktop browsers or media players

Consider FLV to MP3 When:

  • Maximum device compatibility is essential (cars, older devices)
  • Sharing with others who may have limited software

Consider FLV to WAV When:

  • You need uncompressed audio for editing
  • Quality is more important than file size

Audio Quality Expectations

The quality of your OGG output depends entirely on the source FLV file. Most Flash videos used these audio settings:

  • Standard web FLV - 44.1 kHz, 128 kbps (good quality)
  • Low bandwidth FLV - 22 kHz, 64 kbps (acceptable quality)
  • High quality FLV - 44.1 kHz, 192+ kbps (excellent quality)

We extract the audio and encode to OGG at optimal settings. You can't improve upon the original, but we ensure no additional quality loss during conversion.

Works on Any Device

Convert FLV to OGG directly in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android devices

No downloads, no plugins, no accounts. Just upload and convert.

Pro Tip

OGG files work natively with HTML5 audio elements, making them perfect for web developers. If you're extracting audio from old Flash content for a website, OGG eliminates licensing concerns that MP3 technically carries.

Common Mistake

Expecting better quality than the source. FLV files from the mid-2000s often used low bitrate audio to save bandwidth. The conversion will be faithful to the original, but cannot improve upon compressed source audio.

Best For

Game developers and web applications needing audio from legacy Flash content. OGG's open-source nature and efficient compression make it ideal for bundling with software or streaming in browsers.

Not Recommended

If you need to play audio on older car stereos, portable MP3 players, or share with non-technical users. These devices often lack OGG support. Use MP3 conversion instead for maximum compatibility.

Frequently Asked Questions

FLV (Flash Video) was Adobe's video format for web streaming. Common in the 2000s for YouTube and other sites, FLV files contain video and audio but require Flash Player, which was discontinued in 2020.

OGG Vorbis is an open-source audio format popular in gaming, web applications, and media players. It offers better compression than MP3 with no licensing fees, making it ideal for developers and enthusiasts.

Minimal quality loss occurs during conversion. OGG uses efficient lossy compression that preserves audio fidelity well. The output quality depends primarily on your source FLV's original audio bitrate.

Android supports OGG natively. iPhone requires a third-party app like VLC. Desktop browsers (Chrome, Firefox, Edge) all play OGG files directly without additional software.

OGG typically delivers better sound quality at the same file size compared to MP3. It's also completely open-source with no patent restrictions. Choose MP3 only when maximum device compatibility matters.

Yes. Upload multiple FLV files and convert them all to OGG in a single batch. Each file is processed and available for download without repeating the upload process.

No. Our converter processes FLV files directly without needing Flash Player. This works even though Adobe discontinued Flash support in December 2020.

Yes. All processing happens in your browser using client-side technology. Your FLV files are not uploaded to our servers, keeping your content completely private.

Output quality matches your source FLV. Most web FLV files used 128 kbps audio, which converts to good-quality OGG. Higher bitrate sources produce better results.
