How to convert a video to APNG

To convert a video to APNG, load a short MP4 or WebM clip, trim it to the range you want, and set the output width, frame rate, and loop behavior. The tool extracts the frames and encodes them into a single animated PNG you can download. Frame extraction and APNG encoding both run locally in your browser, so the clip is never uploaded.

APNG keeps the animation inside the PNG format, which can render cleaner gradients and crisp UI captures than GIF and fits ecosystems that already use transparent PNG assets. Keeping clips short and the width modest keeps the exported APNG manageable, since longer or larger animations grow quickly in file size.

  • Upload a short MP4 or WebM clip
  • Trim the start and end of the range
  • Set width, FPS, and loop mode
  • Export the animated PNG and download it

When APNG beats GIF for short loops

Animated PNG is a good choice when the workflow should stay in the PNG family, such as UI captures, icon-style loops, and small transparent assets where GIF's limited color handling shows. APNG generally renders smoother gradients and cleaner edges for these cases.

This page keeps the input side simple by accepting ordinary short video clips and turning them into APNG without a second editor. It is optimized for short clips; long videos are heavier to process in the browser and produce large files, so they are not the intended workflow here.

Tips

Getting a better result out of Video to APNG

Specific settings and thresholds, not general advice.

  • Keep the clip short. Start and End are in milliseconds for a reason: APNG stores every frame in full, with no motion compression, so a two-second loop is practical and a twenty-second one is not.
  • 8 to 12 fps is the sweet spot for a UI loop or a reaction clip. The FPS choices stop at the low end deliberately, because every extra frame is a whole image added to the file.
  • Set the output width to what will actually be displayed. Width is the single biggest lever: halving it roughly quarters the pixels in every frame.
  • Choose APNG over GIF when the clip has gradients, soft edges, or transparency. APNG carries 24-bit color and a real alpha channel; GIF has 256 colors and a single transparent index.
  • Convert here, then run the result through the APNG Optimizer. Frame merging and a palette pass on the finished animation do more than any setting during the conversion.
Limits

What Video to APNG does not do

The honest boundary, so you do not lose time finding it yourself.

  • It does not keep audio. APNG is an image format and has no sound.
  • It cannot make a long clip small. APNG has no motion compression, so a long video will always be heavy as an APNG, whatever the settings.
  • It does not crop or rotate. Trim with Start and End, scale with Width, and nothing else.
  • It exports APNG, not GIF or WebP.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is this video to APNG converter free?

Yes. It is a free video to APNG converter with no signup or watermark, and it runs entirely in your browser.

Does it upload my video?

No. Video frame extraction and APNG encoding happen locally in your browser, so your clip is never uploaded.

What inputs does it accept?

It accepts ordinary short video clips such as MP4 and WebM, then converts the trimmed range into an animated PNG.

Is it good for long videos?

No. It is optimized for short clips. Long videos are heavier in the browser and create very large APNG files, so they are not the intended workflow.

Does it preserve alpha from special alpha-video formats?

No. This version focuses on standard short video input and does not promise alpha-video preservation from special formats.

How do I convert an MP4 to an animated PNG?

Open the video, set the Start and End in milliseconds to pick the segment, choose an output width and a frame rate, and export. The frames are decoded and assembled into one APNG in your browser, with no upload.

Why is my APNG so large?

Because APNG stores every frame as a full image and has no motion compression across the timeline. The three levers that matter are the length of the clip, the output width, and the frame rate: cut any of them and the file drops sharply.

APNG or GIF for a short video loop?

APNG if the clip has gradients, soft edges, or needs transparency, because it carries 24-bit color and a real alpha channel. GIF if the clip is flat-color and opaque, where its 256-color palette costs nothing and the file is often smaller.

What frame rate should I pick?

8 to 12 fps for a UI loop or a reaction clip. The options stop low on purpose: in an APNG every extra frame is another full image, so a high frame rate buys smoothness at a very steep price.

Does the APNG keep the sound?

No. APNG is an image format and has no audio track at all.
