Re-wrapping FLV footage as MPEG is what makes it playable and editable outside the device or era it came from, without re-shooting anything. MPEG (MPEG-1/2 video) earns its place here: rock-solid compatibility with players, TVs and disc authoring tools. FLV was the format behind a decade of web video until Flash was retired in 2020. Any FLV you still hold is effectively unplayable without conversion.

Picture and sound are re-encoded into the MPEG container at a bitrate chosen to keep the result visually close to the FLV source. Resolution, frame rate and duration are preserved; file size usually changes noticeably because FLV and MPEG lean on different codecs. Multiple audio tracks or chapter data may not carry over.
What you gain with MPEG: Rock-solid compatibility with players, TVs and disc authoring tools.
Drop your FLV file above and Morphio decodes it locally, then re-encodes it as MPEG using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.
Open the FLV to MPEG page, drop your video on the drop zone and press convert. Morphio runs an FFmpeg build compiled to WebAssembly that runs inside the page, so the FLV data never leaves your device and no server ever receives a copy.
Audio and video tracks are re-encoded together, so the result stays in sync and plays on standard players. Converting FLV to MPEG only rewrites the container and encoding you asked for — the source file on your disk is never modified.
Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.
Morphio decodes the FLV file at full fidelity and re-encodes it at a high-quality MPEG setting, so the difference is normally invisible or inaudible. What conversion cannot do is recover detail the original FLV file already threw away.
Yes — drop the whole batch in and each file is processed in turn on your own machine. The practical limit is your device's memory and patience, not a server quota, because nothing is queued anywhere else.
No. The conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can disconnect from the internet after the page loads and it still works.
