Convert SWF to MP4

Verified by Adam B.· reviewed by FE Editorial ·updated Aug 4, 2026
QUICK ANSWER
Is it possible to convert SWF to MP4?
Yes - SWF converts to MP4.

Open the .swf in Ruffle, record the playback with OBS Studio, and save as MP4. This screen-recording approach is the only reliable method in 2026 because Adobe Flash Player was killed in December 2020 and all direct converters depended on it.

Why convert SWF to MP4?

SWF (Small Web Format) is compiled Flash software - interactive, not a linear video file. Adobe Flash Player reached end-of-life on 31 December 2020 and has blocked all Flash content since January 2021. Converting to .mp4 lets you share or archive the content anywhere without depending on Flash emulation.

How to convert SWF to MP4

OBS Studio + Ruffle FREE

Install Ruffle (ruffle.rs) and open the .swf in it; in OBS Studio add a Window Capture source for the Ruffle window, click Start Recording, and play through the SWF - OBS saves the output as MP4.

Adobe Premiere Pro APP

After recording the SWF playback via OBS, import the file into Adobe Premiere Pro to trim or color-correct, then export as .mp4.

Quality & what to watch

  • SWF is interactive, not a linear video - any interactive elements must be performed during recording, as no tool can auto-play a deterministic path through interactive content.
  • For non-interactive, timeline-based animations, SWFTools (swfrender) can rasterize frames for assembly into MP4 with FFmpeg, but ignores audio and ActionScript.
  • ActionScript 1 and 2 content plays reliably in Ruffle; ActionScript 3 support is incomplete as of 2026.

Frequently asked questions

Why don't tools like Freemake Video Converter work on `.swf` files?
Those tools relied on Adobe Flash Player to render SWF content; since Flash Player was killed in 2020, they no longer function for this task.
Does OBS capture audio from the SWF?
Yes - OBS captures system audio during recording, so any audio that plays in the Ruffle session is included in the MP4.
Can I convert a simple SWF animation without screen-recording?
For non-interactive, timeline-based animations only - SWFTools (swfrender) exports frames as PNG images which FFmpeg can assemble into an MP4, but audio and ActionScript logic are not captured.
