How to Convert SWF to MPEG Online
- Upload Your SWF File: Drag and drop or click "Add Files" to select SWF (Adobe Flash) files — Flash video players, exported Flash videos, or e-learning courseware (Articulate / Captivate / Lectora) with an embedded video track. Batch is supported for processing several
.swffiles at once. - Pick the MPEG Video Codec: Default is MPEG-2 — the DVD-Video codec and the most universally supported choice for an
.mpegfile in 2026. Choose MPEG-1 for VCD authoring and the broadest legacy player support, MPEG-4 / XVID / DIVX for smaller files inside an MPEG-family container, or H.264 for modern decoders that accept MPEG transport streams. Audio defaults to MP2 (DVD-compliant); MP3, AC-3, and AAC are also exposed under the audio codec picker for non-DVD targets. - Set Quality, Resolution, and Trim (Optional): Pick a quality preset (Highest → Very High → High → Medium → Low → Very Low → Lowest) or fine-tune with qscale (1-31 for MPEG-1 / MPEG-2 / MPEG-4 — qscale 2-5 is high quality, 6-10 is standard) or CRF (16-51 for H.264 inside MPEG). Under Video resolution pick a Preset Resolution (4320p, 2160p, 1440p, 1080p, 768p, 720p, 648p, 576p, 480p, 360p, 240p, 144p) — these set height only, with the width following the stage's aspect ratio — or enter an exact Width × Height, which is what you need for a DVD-legal 720x480 (NTSC) or 720x576 (PAL) frame. You can also scale by percentage or keep the original size. Most original SWFs were authored at 480p or smaller; upscaling rarely helps. Trim with start time + duration in HH:MM:SS.sss format.

Why Convert SWF to MPEG?
SWF (originally Shockwave Flash, later Small Web Format) was Adobe Flash's container for vector animation, web games, and embedded video from the late 1990s through the early 2010s. Adobe officially end-of-lifed Flash Player on December 31, 2020, and Chrome, Firefox, Edge, and Safari removed Flash support in early 2021 — every modern browser refuses to load .swf files. MPEG is the opposite: an ISO/IEC standards family (MPEG-1 from 1993, MPEG-2 from 1995) so universally supported that it plays on virtually every DVD player, set-top box, smart TV, and legacy media device ever made. Converting SWF → MPEG is a niche but specific job — usually about getting old Flash content onto physical media or into a system that predates HTML5:
- DVD-Video authoring from Flash assets — DVD authoring software (DVD Flick, DVDStyler, ConvertXtoDVD, Adobe Encore) requires MPEG-2 video at 720x480 (NTSC) or 720x576 (PAL) inside an
.mpeg/.mpg/ VOB container. SWF is not an accepted input. This is the most common reason people still convert to MPEG in 2026 — preserving Flash animations or e-learning modules onto a playable DVD-Video disc. - Playback on legacy hardware — Old DVD players, in-car DVD systems, museum kiosks, hotel-room set-top boxes, and pre-2010 media boxes play MPEG natively but never supported SWF. Converting an archived Flash training video to MPEG lets it play on hardware that has no Flash projector and no Ruffle build available.
- VCD / SVCD authoring — Video CDs use MPEG-1 at 352x240 / 352x288; Super Video CDs use MPEG-2 at lower resolution. Both still see use for archival projects and regions where DVD blanks are scarce. Pick the MPEG-1 codec at VCD resolution to author a VCD from an old Flash video.
- Editing in older NLE software — Premiere 6, Final Cut Pro 7, Vegas 9, and other pre-2012 editors handle MPEG natively but cannot ingest SWF at all. Converting to MPEG lets you cut Flash-era footage in legacy edit suites still running in production environments — broadcast affiliates, training-video shops, courthouse video archives.
- Broadcast and capture pipelines — Some TV studios, surveillance systems, and broadcast automation tools accept only MPEG-2 program streams or transport streams. Converting old Flash-era assets makes them ingestible without a parallel transcoding step.
- Long-term offline archiving — MPEG-2 is a public ISO/IEC 13818 standard with patents largely expired worldwide by 2018, decoded by every player ever built. SWF depends on a discontinued plugin and a shrinking pool of emulators. For a 30-year archival horizon, MPEG is more durable than SWF.
For modern web embedding, social media, or mobile playback, convert to SWF to MP4 instead — MPEG files are large and don't stream well over HTTP. MPEG's strength is DVD authoring, legacy hardware, and broadcast pipelines, not the modern web. For desktop playback in legacy editors, SWF to AVI is also worth considering. The output of this tool is interchangeable with SWF to MPG — .mpeg and .mpg are the same container with different file extensions.

Frequently Asked Questions
Is .mpeg the same as .mpg?
Yes — they are the same container with different file extensions. The 3-letter .mpg survives from the Windows 8.3 filename era; .mpeg is the longer modern form. Both contain MPEG-1 or MPEG-2 program streams (or sometimes MPEG-4 / H.264) with MP2, AC-3, or LPCM audio. Renaming file.mpeg to file.mpg does not change the bytes inside. Some DVD authoring tools default to writing .mpg; some media-asset systems prefer .mpeg. Pick whichever extension your downstream tool expects.
Should I pick MPEG-1 or MPEG-2?
MPEG-2 for almost everything in 2026 — it's the DVD-Video codec, plays on every DVD player and smart TV, and patents have largely expired. MPEG-1 only if you're authoring a Video CD (VCD) or targeting truly ancient hardware (1990s set-top boxes, early portable players). MPEG-2 at DVD resolution (720x480 NTSC / 720x576 PAL) and 4-6 Mbps is the standard recipe for burning Flash content to DVD.
Will the converted MPEG burn directly to a DVD?
Almost — but check two things. The MPEG must be MPEG-2 video at a DVD-compliant resolution (720x480 for NTSC, 720x576 for PAL) and audio must be MP2, AC-3, or LPCM (not MP3 or AAC). Pick MPEG-2 and MP2 in the codec dropdowns, type the matching frame into Width x Height (the Preset Resolutions list sets height only, so it cannot pin a DVD raster), then feed the output into DVD Flick, DVDStyler, or ConvertXtoDVD to build the VOB / IFO / BUP structure required by the DVD-Video spec.
Will the animation look as crisp as the original SWF?
Only as sharp as the video inside the SWF. That video was encoded at a fixed size — usually 480p or smaller — and the MPEG keeps it; DVD output caps you at 720x480 / 720x576, which already covers most Flash-era video. For a sharper copy of a larger embedded video, convert to SWF to MP4 at its original size instead.
Can I convert interactive SWF games to MPEG?
No. A Flash game is vector shapes and ActionScript with no video inside, so there's nothing to convert — we tell you right after upload. To keep a video of the gameplay, screen-record (OBS, Windows Game Bar) the SWF running inside Ruffle or the standalone projector, then save the recording. To preserve interactivity itself, use Ruffle or Flashpoint instead — both are designed for that.
Why is my MPEG so much larger than the SWF?
The video inside a SWF was usually compressed hard for 2000s-era connections. MPEG (especially MPEG-2 at DVD bitrates, 4-9 Mbps) spends far more bits per minute, so the same minute often becomes 30-70 MB. If file size matters more than DVD compatibility, SWF to MP4 with H.264 / H.265 is dramatically smaller for the same visual content.
Will the audio survive the conversion?
Yes. SWF's MP3 / ADPCM / Nellymoser / Speex audio is decoded and re-encoded to your chosen output codec. Default is MP2 (DVD-compliant). AC-3 (Dolby Digital) is also DVD-compliant and tends to sound better at low bitrates. MP3 and AAC are fine for software playback but break DVD-Video spec. Pick MP2 or AC-3 if the MPEG is destined for a DVD; MP3 or AAC are fine for VLC / Windows Media Player playback.
My SWF won't play in any modern browser — will the MPEG?
Yes — that's the point. Browsers, mobile players, and most modern apps stopped supporting SWF in 2020 when Adobe killed Flash. MPEG (especially MPEG-2) plays in VLC, Windows Media Player, every DVD player ever made, and most smart TVs. Converting to MPEG resurrects unplayable Flash archives onto hardware that has no Flash projector and no Ruffle build.
