Convert MPEG2 to APNG Online

Convert MPEG-2 to APNG Online

APNG turns a slice of video into a single looping image that works anywhere a PNG works — chat, wikis, issue trackers, documentation — with full 24-bit colour and lossless frames, which is what separates it from GIF's 256-colour palette. The catch is scale: MPEG-2 is a long-form broadcast and DVD format built around inter-frame compression, while APNG stores complete lossless frames. This page therefore has exactly two controls that matter, Image resolution and Framerate, and getting a sensible file out depends almost entirely on them plus how short your source clip is.

How to Convert MPEG-2 to APNG

1. Upload Your MPEG-2 File: Drag and drop a .mpeg2 file or click "+ Add Files". The whole file is converted — this page has no trim control — so cut long captures down to the seconds you want before uploading.
2. Set the Framerate: The Video Framerate dropdown defaults to 10 FPS (Recommended) and ranges from 1 FPS to 50 FPS. Each frame becomes a full lossless image, and the per-frame delay is exactly 1/fps, so this control sets both smoothness and file size.
3. Set the Image Resolution: Keep original is selected by default. Preset Resolutions set a height and let width follow the source aspect, with a "Use as max resolution" option; Resolution Percentage, Width, Height and Width x Height are also available. Scaling happens while frames are extracted.
4. Convert and Download: Click Convert and download the .apng. Frames are assembled into an infinitely looping animation and then run through a lossless optimiser. Files upload over an encrypted connection, convert on our servers, and are deleted automatically a few hours later.

Why the File Gets Big, and the Two Levers That Fix It

A DVD-resolution frame at 720x480 is 1,382,400 bytes of raw RGBA. Lossless PNG compression typically brings a real-world frame down to a few hundred kilobytes — nowhere near what MPEG-2 achieves, because MPEG-2 stores most frames as differences from their neighbours while APNG stores frames outright. Duration multiplied by framerate is the number of frames, and frames are the whole story:

The two levers are on the page: lower the Framerate (10 FPS is already the default, and 8 or 5 FPS is fine for slow motion or a screen recording), and cut the frame size with Image resolution — halving the height roughly quarters the pixel count and the bytes with it. The third lever is not on this page: shorten the clip. Use the Video Cutter on your source first, then convert the trimmed clip here.

APNG, GIF, and Animated WebP

APNG is no longer an unofficial extension — it was folded into the PNG specification itself in PNG Third Edition, published as a W3C Recommendation on 24 June 2025, which defines the image/apng media type alongside the acTL, fcTL and fdAT chunks that carry the animation.

For a DVD or broadcast clip specifically, GIF is often the more sensible target — real footage rarely benefits from lossless frames, and MPEG-2 to GIF will produce a far smaller file. Choose APNG when colour banding or clean edges actually matter.

Common Errors and How to Fix Them

• "The APNG is enormous" — Expected with a long clip or a high framerate. Cut the source first, then drop Framerate and Image resolution. There is no quality or file-size control on this page because APNG frames are lossless by definition.
• "The whole recording got converted" — There is no trim control here; the full duration is used. Trim the source with the Video Cutter before uploading.
• "Motion looks juddery" — 10 FPS is the default and it shows on fast pans. Raise the framerate to 15, 20 or 25 FPS and compensate by reducing the resolution, or the file grows quickly.
• "The picture has comb lines through moving objects" — Your MPEG-2 is interlaced, which is normal for DVD and broadcast captures. Nothing in the pipeline deinterlaces, so both fields land in one frame and the combing is baked into the APNG. Deinterlace in a desktop editor first if it matters.
• "Everything looks horizontally squashed" — Anamorphic DVD footage stores non-square pixels, and PNG frames are always square-pixel. Set an explicit Width x Height matching the intended display shape (for example 854x480 for 16:9 NTSC material) rather than keeping the original.
• "It shows only the first frame" — The viewer does not support APNG and is falling back to the still image, which is the format's intended behaviour. Convert to GIF for that audience.

Frequently Asked Questions

Why is there no trim, quality, or file-size control on this page?

Because APNG is a lossless format, there is no quality dial to expose — every frame is stored exactly. And this conversion runs over the whole source duration, so no trim control is rendered either. That leaves Framerate and Image resolution as the only settings, which is why the guidance here is to cut your clip before uploading rather than after.

How long a clip is realistic?

A few seconds. At 10 FPS, five seconds is 50 lossless frames — manageable if you also reduce the height. Fifteen seconds at DVD resolution is already unwieldy, and a full chapter is not a sensible APNG at any setting. If you need the whole recording to stay watchable, keep it as video with MPEG-2 to MP4.

Why is the APNG so much larger than the MPEG-2 file?

Different compression models. MPEG-2 encodes most frames as differences from a nearby reference frame and throws away detail your eye is unlikely to notice. APNG stores each frame as a complete lossless image; a 720x480 frame alone is 1.38 MB before compression. Ten of those per second adds up fast no matter how efficient the PNG encoder is.

Does the APNG keep full colour, and what about transparency?

Frames are extracted in truecolour with an alpha channel intact and are never palette-reduced on this page, so gradients and fine detail survive exactly. Video itself carries no transparency, though — MPEG-2 has no alpha channel — so the alpha capability only matters if you later composite the APNG over something else.

Is APNG a real standard or a browser extension?

It is a real standard now. PNG Third Edition, a W3C Recommendation dated 24 June 2025, incorporates the animation chunks into the PNG specification itself and defines image/apng as an official media type. Before that it lived as a Mozilla-originated extension, which is why some older tooling still treats it as unofficial.

Will the APNG play everywhere?

In current browsers, effectively yes — caniuse puts global support near 96%, covering Chrome 59+, Firefox 3+, Safari 8+ and Edge 79+. Where support is missing, the file degrades gracefully to its first frame as a static PNG rather than breaking. Some desktop image viewers and older chat clients also show only the first frame.

Should I use GIF instead?

For camera footage, usually yes. GIF's 256-colour palette is a poor fit for gradients but a fine fit for compressed video frames, and the file will be a fraction of the size — MPEG-2 to GIF is the pragmatic choice. Prefer APNG for screen recordings, titles, logos and animation, where banding in a palette is obvious.

Can I make an existing APNG smaller?

Yes. The output here is already run through a lossless optimiser, but if you need to go further, the APNG Compressor offers palette and colour reduction that this conversion page deliberately does not. Re-running an APNG through it usually beats re-converting the video at a higher framerate.

How is my file handled?

It is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — never shared, never made public, no sign-up required. The practical limit is upload size and time: a full DVD-length .mpeg2 takes a long while to send, which is another reason to trim before you upload.
