Should you convert WEBM to PNG?
Yes, whenever you need pictures out of a clip: a thumbnail, a still for a document, or evidence from dashcam footage. The WEBM isn’t changed; stills are saved beside it as PNG files.
WEBM is the web’s open video format, holding VP8, VP9 or AV1 video with Opus or Vorbis audio; PNG is a lossless image format with full transparency. Use PNG for screenshots, interface graphics, logos and anything with transparency or lettering, and as the working copy of an image you are still editing.

How to convert WEBM to PNG
- 01
Add your WEBM
Drop your WEBM video onto the box, or click to choose it. It is read from your disk and stays there.
- 02
Check the settings
Choose one frame, one per second or every frame, and PNG or JPG.
- 03
Save the stills
Press convert and save the stills. Several files come back together as a ZIP.
What changes when WEBM becomes PNG
One frame, or many
Save a single frame at the moment you type, one frame every few seconds, or every frame of a short clip, up to 3,000 stills. Many stills download together as a ZIP.
PNG keeps every pixel
PNG stills are an exact copy of each decoded frame, which suits screenshots of text or footage you’ll edit. They are several times larger than JPG.
Stills are only as sharp as the video
A frame from compressed video carries the video’s compression, and fast motion blurs. Pick a moment with little movement for the clearest picture.
This page is put together from our notes on each format, choosing only what is true of WEBM and PNG, so every pairing states the same facts the same way. How these pages are made.
Why it doesn’t upload
A still from your own video shouldn’t require sending the whole video to a server. Frames are decoded and saved on your device, and the video never leaves it.
How to check for yourselfWorth knowing
- About the WEBM. Browser screen recorders save WEBM, and the recording then fails to upload or attach almost everywhere else.
- About the PNG. Photographs saved as PNG balloon in size. A holiday photo that is 3 MB as JPG can be 15 MB as PNG, because lossless compression can do very little with the fine grain of a real photograph.
- AVI, WMV, FLV and other older formats use the FFmpeg engine, a one-time 31 MB download.
Questions
How do I get a single frame from a WEBM as PNG?
Add the video, choose “One frame”, type the moment in seconds and save it. The PNG is exactly the size of the video frame.
Can I save every frame of a WEBM?
Yes. A short clip at 30 frames a second gives 30 PNG files per second, bundled into a ZIP. For long videos, one frame per second is usually enough.
