Convert FLV to MP4 — Free Flash Video Converter

FLV (Flash Video) was once the backbone of online video—YouTube, Vimeo, and countless websites delivered content in Flash format. But Flash is now officially dead, and FLV files are digital fossils. Converting FLV to MP4 rescues your Flash videos for playback on modern devices that no longer support Flash.

Our FLV to MP4 converter handles all Flash Video variants, from ancient Sorenson Spark encoded files to newer H.264-in-FLV containers. Whether you're digitizing old video archives or recovering downloaded Flash content, the conversion produces clean, modern MP4 files.

Flash Player is discontinued and blocked by all major browsers. FLV files simply won't play on modern systems without specialized software. iOS never supported Flash. Android dropped support years ago. Converting to MP4 is necessary for these files to remain viewable.

Beyond playability, FLV conversion enables editing and sharing. Video editing software increasingly drops FLV import support. Social media platforms reject FLV uploads. Cloud storage services may not generate previews. MP4 solves all these issues.

Historical preservation matters too. Early web videos, Flash animations, and online content from the 2000s often exists only as FLV. Converting ensures this content survives for future viewing.
