Need help?MPEG-2 to SWF Converter
MPEG-2 is the 1990s broadcast and DVD video standard; SWF is the Macromedia/Adobe Shockwave Flash container that powered web animation and video for over a decade. This converter re-encodes an MPEG-2 program stream into a Flash SWF, which is useful only for legacy Flash projectors, old authoring projects, or archival workflows. Adobe ended Flash Player support on December 31, 2020 and began blocking Flash content from running on January 12, 2021, so for anything you actually need to play today, convert to MP4 instead.

How to Convert MPEG-2 to SWF
- Upload Your MPEG-2 File: Drag and drop your .mpeg2 file onto the page or click "+ Add Files" to choose one or several from your device.
- Confirm Output and Quality Preset: SWF is already selected as the output; the video re-encodes with the Flash (FLV1) codec and MP3 audio. Pick a Quality Preset such as "Very High (Recommended)" or set a Specific file size under File Compression.
- Adjust Resolution or Trim (Optional): Use a Preset Resolution to scale the frame down, or set a Time Range under Trim to export only part of the clip.
- Convert and Download: Click "Convert" and download your SWF. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours. No sign-up, no watermark.
Frequently Asked Questions
Will converting MPEG-2 to SWF lose quality?
Yes, some loss is expected. This is a re-encode from one lossy codec (MPEG-2) to another (Sorenson Spark / FLV1, an older H.263 variant), so it goes through a second generation of compression. Keep the Quality Preset high to minimize visible artifacts, but the source MPEG-2 will always be the better-looking copy.
Can I still play an SWF file in 2026?
Not in a normal browser. Adobe ended Flash Player support on December 31, 2020, and modern versions of Chrome, Firefox, Edge, and Safari removed the Flash plugin. The open-source Ruffle emulator opens many older SWFs in the browser or as a desktop app, and standalone Flash projector executables still run them, but there is no first-party player anymore.
Why would anyone convert MPEG-2 to SWF today?
Almost the only real reasons are legacy: importing a clip into an old Flash (.fla) authoring project, feeding a standalone Flash projector, or matching a format an obsolete e-learning or kiosk system still expects. If your goal is simply to play or share the video, SWF is the wrong target and MP4 is the right one.
What video and audio codecs does the SWF output use?
On this converter the SWF is written with the Flash video codec (FLV1 / Sorenson Spark, a proprietary variant of H.263) and MP3 audio, which is the combination classic Flash Player expects inside an SWF. It does not embed the original MPEG-2 (H.262) stream; the video is fully re-encoded.
Should I convert to MP4 instead of SWF?
For any modern use, yes. MP4 with H.264 plays natively in every current browser, on phones, smart TVs, and editors, while SWF plays in almost nothing. Use MPEG-2 to MP4 for a future-proof file, or SWF to MP4 if you already have a Flash file you need to rescue.
Is there a sign-up or watermark?
No. There is no account, no watermark, and no public gallery. Your file is uploaded over an encrypted connection, converted on our servers, and deleted automatically after a few hours.
