Source format
FLV is a legacy web video container with limited support in modern browsers and devices.
FLV
FLV (Flash Video) is a video container that was used by Adobe Flash Player for web video. It typically holds H.264, VP6, or Sorenson Spark video with AAC or MP3 audio. Browsers no longer support Flash, so FLV files are usually converted to MP4.

What happens when FLV becomes FLV
Target format
FLV is a legacy web video container with limited support in modern browsers and devices.
What changes
The file is decoded and written as a fresh FLV file. For JPEG to JPG, the image encoding is the same and the practical change is the extension.
- What is preserved
- Duration and audible content are preserved, subject to decoder support and any settings you change.
- What may be lost
- Metadata may be rewritten, and re-encoding with changed settings can alter quality even when the extension stays the same.
- Codec and quality implications
- Inspect the output before replacing the source, especially when the formats use different layout, codec, or editing models.
- Realistic limitations
- Password protection, corruption, missing fonts, macros, embedded objects, and unusually complex layouts can change or prevent conversion.
Conversion steps
- Upload a FLV file no larger than 1 GB.
- Confirm that FLV is selected as the target.
- Open settings only if you need to change codec, quality, bitrate, frame rate, resolution, or audio behavior.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the FLV file and check the result before deleting your source.
Troubleshooting
- The FLV file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The FLV file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
Privacy and file retention
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
