WebP to MPEG Converter

How to Convert WebP to MPEG Online

1. Upload Your WebP Files: Drag and drop your .webp images, or click "+ Add Files" to select them. Batch upload is supported — every image becomes a frame in the output video. Animated WebP (extended format, added by Google on 3 October 2011) is treated as its source frames; static WebP is shown for the duration you set.
2. Pick a Merge Strategy and Image Duration: Choose Merge images to combine every upload into one MPEG slideshow, or Video per image to get a separate .mpeg file for each input. Set Image Duration (default 5 seconds per frame; pick anything from 1/60 sec for stop-motion to 10 sec for slideshows). Set Background Color (default Black) — it fills the letterbox when an image's aspect ratio doesn't match the output.
3. Set Quality and Resolution (Optional): Pick Constant Quality (target a visual quality level — file size varies) or Constraint Quality (cap the bitrate — quality varies). Choose a preset from Very Low to Very High (Recommended). For resolution, keep Original or switch to Fixed Resolutions and pick a preset (1080p, 720p, 480p) or enter custom width/height. Aspect ratio is preserved by default.
4. Convert and Download: Click Convert. Files process privately in your session — no sign-up, no watermark, no email required. Download individual .mpeg files or grab the whole batch as a zip.

Why Convert WebP to MPEG?

WebP, released by Google on 30 September 2010, dominates the modern web with ~97% browser support, but it's still an image format with image/webp MIME type — most video editors, set-top boxes, and broadcast systems won't touch it. MPEG (MPEG-1 / MPEG-2 program stream, ISO/IEC 11172 and 13818) is the opposite: it's the lingua franca of legacy video pipelines, DVD authoring, VCD/SVCD discs, and broadcast TV equipment.

• Slideshow video from a WebP batch — Turn 20 WebP screenshots or photos into a single MPEG with controlled pacing. Useful for kiosk loops, ambient displays, or quick demos where you'd otherwise need a video editor.
• Burn to Video CD or SVCD — VCD requires MPEG-1 Video at 352x240 (NTSC) / 352x288 (PAL) under 1.5 Mbit/s. MPEG output from a WebP source is the right starting point for set-top-box playback on hardware that won't read MP4.
• DVD-authoring source — DVD-Video uses MPEG-2 program streams. Authoring tools like DVDStyler and TMPGEnc Authoring Works ingest .mpg and .mpeg natively; WebP is rejected.
• Drop into Premiere Pro / DaVinci Resolve — Premiere Pro and Resolve both refuse animated WebP on import. Convert to MPEG first and the timeline accepts it without transcoding.
• Share an animated WebP as video — Reddit, Discord, Twitter, and many CMS uploaders treat WebP as a still image even when it's animated. An MPEG plays back as motion video everywhere a video player exists.
• Long-term archive of source images — MPEG-1 has been a published ISO standard since November 1992 and will outlive most modern codecs in terms of decoder availability. A .mpeg made today still plays on a thirty-year-old MPEG decoder.

WebP vs MPEG — Format Comparison

Image-Duration Quick Guide

Most player software re-pulses static frames internally, so a 1080p slideshow at 1 fps is dramatically smaller than the same content at 30 fps without any visible difference.

Frequently Asked Questions

Why doesn't my video editor accept WebP directly?

Premiere Pro, Final Cut Pro, and DaVinci Resolve don't ship WebP demuxers because WebP is registered as an image format (image/webp), not a video format. Even animated WebP is treated as a single image file by their import pipelines. Converting to MPEG sidesteps the issue — every NLE has read MPEG-1/2 since the late 1990s.

Should I pick MPEG-1 or MPEG-2 for my output?

The xconvert encoder targets MPEG-1 Video by default because it's universally decodable, including on hardware as old as VCD players from 1993. Choose MPEG-2 only if you specifically need DVD-Video compliance, broadcast-spec capture cards, or higher-than-VCD resolutions. For modern web playback, neither is ideal — use WebP to MP4 instead.

Will my animated WebP keep its motion in the MPEG?

Yes — the converter extracts each frame of the animated WebP and lays them onto the timeline at your selected Image Duration. If you want to preserve the original animation's playback speed, set Image Duration to match the WebP's frame delay (most animated WebP files run at 1/24 sec or 1/30 sec per frame).

Why is my MPEG file so much larger than the source WebP?

WebP at high compression can hit 25-34% smaller than equivalent JPEG. MPEG-1 Video targets ~1.15 Mbit/s for VCD-compliant output and supports up to 100 Mbit/s, plus it stores 30 redundant frames per second of mostly-identical pixels for a slideshow. Expect a 50 KB WebP slideshow source to produce a 5-15 MB MPEG at default settings. Lower the bitrate preset or use Constant Quality "Low" if size matters more than visual quality.

Does the output play on a DVD player or a Video CD player?

It plays on most hardware MPEG decoders, but VCD and DVD compliance is stricter than the file format alone. VCD requires 352x240 (NTSC) or 352x288 (PAL) at 1.15 Mbit/s with MP2 audio at 224 kbit/s. Pick the matching resolution preset and use Constraint Quality to cap the bitrate; then use a VCD-authoring tool like cdrdao or Nero to burn the resulting .mpeg to disc.

Can I add background music to the MPEG slideshow?

Not in the current WebP-to-MPEG flow — output is video-only (MPEG container without an audio track). If you need a soundtrack, render the MPEG here first, then mux audio in with FFmpeg (ffmpeg -i in.mpeg -i track.mp3 -c:v copy -c:a mp2 out.mpeg) or use a desktop NLE like Shotcut or DaVinci Resolve. Audio-track upload for the image-to-video pipeline is on the roadmap; it's not live yet.

What's the largest WebP I can upload?

Files are uploaded over an encrypted connection and processed on our servers — there's no per-file hard cap, only upload bandwidth and our server-imposed quota. A 4K WebP (3840x2160) is typically 1-4 MB and converts in a few seconds; a batch of 100 such files into one MPEG slideshow is the realistic upper limit for most sessions. Animated WebP with hundreds of internal frames may take noticeably longer because each frame is decoded individually.

Does this work on iPhone and iPad?

Yes — Safari on iOS 14+ supports the underlying WebP decode and the MPEG output downloads as a standard .mpeg file. iOS Photos won't import .mpeg directly (it prefers MP4), so for camera-roll use, convert WebP to MP4 and AirDrop the result instead.

Will the converted MPEG include transparency from my WebP?

No. MPEG-1 and MPEG-2 video have no alpha channel — they're 8-bit YCbCr 4:2:0 only. Any transparent regions in your WebP get composited against the Background Color you choose (default black). If you need transparency in the output, you need an entirely different format like Apple ProRes 4444 or VP9 in WebM.
