WebM to Image Conversion FAQ

How do I extract frames from a WebM video as Image images?

Upload the WebM and open the options. Frame Extraction has two modes: Single Frame saves one Image from the second you enter (for example 1, 5 or 10.5), and All Frames saves every frame of the video as an Image image. There is no every-Nth-frame or one-per-second mode. WebM is a strict subset of Matroska that Google published in 2010 specifically to give HTML5 video a royalty-free container. Image here is a generic target: the converter picks a sensible raster format for the source rather than forcing one on you.

Will subtitles show up in the Image frames I extract?

Not if they are a real subtitle track. A WebM keeps subtitles as their own stream and the player draws them over the picture at playback time, so the decoded frame the converter writes out as an Image has clean pixels underneath. Subtitles that were burned into the video before it ever became a WebM are a different matter — by then they are part of the image and every extracted frame keeps them.

Does the Image output support transparency?

The format does, but the source has no alpha to give it — video frames and rendered pages are fully opaque by nature, so every pixel arrives solid. The alpha channel is still useful afterwards: it means you can cut a subject out of the Image later without changing format again. Choosing the target automatically means you get a file that opens anywhere without having to reason about codecs first.

How big will the Image files be?

Larger than you might expect, because Image keeps every pixel exactly rather than approximating. A 1080p still lands around 2-5 MB and a 4K still around 6-15 MB, so a long extraction run adds up quickly. That is the right trade when the images feed further processing, and the wrong one when they are going straight onto a web page. A multi-page source produces one image per page, each as a separate download.

At what resolution does each extracted Image frame come out?

The same resolution as the WebM video — a 1080p WebM produces 1920×1080 Image frames; a 4K WebM produces 3840×2160 Image frames. Use the resize utility after extraction if you want smaller thumbnails or social-media-sized crops.

Can I extract every single frame from WebM as Image?

Yes, with All Frames in the Frame Extraction option, but watch the count: one minute of 30 fps video gives 1,800 Image images. For a single still, choose Single Frame and enter the second you want instead.

Will the extracted Image images preserve the WebM color grading?

HDR footage is not tone-mapped: each frame is converted from the WebM as it is decoded, so a frame from an HDR WebM can look flat or washed out as an Image. Standard (SDR) video keeps its colours.

What is the file size of one extracted Image frame?

Depends on resolution and Image codec. A 1080p PNG frame is typically 2 to 5 MB; a 1080p JPG at quality-85 is 200 to 500 KB; a 4K PNG is 6 to 15 MB. At the extreme, every-frame PNG extraction of a 10-minute 1080p WebM produces ~50 GB total.

How long does frame extraction from WebM to Image take?

It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.

Can I extract frames at specific timestamps in the WebM?

One at a time. Single Frame takes one time in seconds (for example 83 for 1:23) and saves that frame as an Image. There is no field for a list of times, so run the conversion again for each extra timestamp.

Is my WebM video private during frame extraction?

Yes. Uploaded WebM files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted Image are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
