How do I convert SWF to FLV with LetsConvert?

Upload your SWF file, choose FLV as the output, and optionally adjust video/audio bitrate, DPI, and frame rate. Click Convert, then download the FLV file. For batch conversions, select multiple SWF files to process in parallel.

Why should I convert SWF to FLV instead of keeping the original?

SWF is a vector-based format for interactive Flash content, while FLV is a video container ideal for streaming on websites, mobile devices, and media players. Converting removes the need for a Flash player, reduces file size through H.264/AAC compression, and ensures playback on HTML5 video pipelines.

What happens to transparency, audio, and layers when converting SWF to FLV?

Transparency is preserved if you select a codec with an alpha channel, such as VP6 or H.264 with alpha; otherwise, transparency is flattened to a black background. Audio is re-encoded to AAC or MP3 with your chosen bitrate, and vector layers are rasterized to a fixed resolution at the specified DPI, so complex masks and meshes are baked into the video frames.
