An FLV file (Flash Video) is a one-time trendy video format used for online streaming through Adobe Flash Player. Popular platforms, including YouTube, Facebook, and news sites, used FLV in the 2000s because it allowed fast web playback.

However, Adobe Flash Player was discontinued in 2020, and therefore most browsers and devices no longer support FLV files. If you try to open an FLV video today, it may not play at all or only show sound without video.

FLV is an outdated format created for the Flash plugin. It used old codecs like Sorenson Spark or On2 VP6 for video and Nellymoser for audio. These codecs are no longer native on modern devices.

MP4, on the other hand, employs advanced H.264 or H.265 video compression and AAC audio, making it the global standard for digital video. It is lightweight, high-quality, and compatible with all major platforms.

Therefore, the conversion of FLV to MP4 makes your old FLV videos playable, editable, and shareable anywhere without a single glitch.

When you convert FLV to MP4 with AhaConvert, the converter will re-encode the video and audio with the latest codecs and preserve the original resolution, frame rate, and quality. The FLV container will be replaced by MP4.

After conversion, your new MP4 video file will:

• Play perfectly on any modern media player and device
• Open easily in video editors
• Take up less storage space compared to the original FLV

Yes, you can freely convert FLV videos to MP4 for free in your browser. There is no software to install and no account required for simple conversions.

Yes. Long, large FLV videos like full tutorials, game streams, and saved live videos can be converted smoothly with AhaConvert. The upload time depends on your internet speed and specific file size, but the conversion itself has been optimized for stability and speed.

For the best experience, please use a reliable Wi-Fi connection and do not shut down the browser window until your download link pops up.

Of course. FLV was only meant for web streaming, not for editing. Many editing programs cannot import FLV videos directly. MP4 is fully supported by Adobe Premiere Pro, Final Cut Pro, CapCut, and many other leading editors.

Once converted, your MP4 file will open instantly, play smoothly on the timeline, and export more quickly. No need to install extra codecs or plugins.

Absolutely. All the video files, whether uploaded or downloaded, are kept safe during processing. We use 256-bit SSL encryption, store files in a secure cloud environment, and automatically delete them within 24 hours.
