Upload the WebM file and the converter exposes a frame-extraction picker: every Nth frame, frames at specific timestamps, or one frame per second. Each chosen frame is decoded from the WebM video stream, encoded as a separate PNG file, and bundled as a ZIP for download.
At what resolution do the extracted PNG images come out?
+
Same resolution as the source WebM: a 1080p WebM produces 1920x1080 PNG frames, a 4K WebM produces 3840x2160 PNG frames. The converter does not upscale or downsample — pixel dimensions are pulled straight from the decoded frame. Use /resize-image/ after extraction if you need smaller thumbnails.
Can I extract every frame of a WebM as PNG?
+
Yes, but mind the file count — a 30 fps 1-minute WebM produces 1,800 PNG frames. We pack them into a single ZIP archive automatically. For longer clips, prefer the "1 per second" preset (60 frames per minute) or pick specific timestamps. An hour of WebM at every-frame would produce ~100,000 PNG images.

How big is one extracted PNG frame on disk?
+
Depends on resolution and PNG codec choice: a 1080p PNG frame is 2-5 MB lossless, a 1080p JPG at quality 85 is 200-500 KB. Multiply by frame count to size the ZIP — at the extreme, every-frame PNG extraction of a 10-minute 1080p WebM is roughly 50 GB and gets split across multiple ZIPs.

A WebM container does not carry per-frame EXIF the way a still camera does, so the PNG files come out with empty EXIF blocks. The converter does embed a `creation_time` field pointing at the source frame timestamp, so you can re-sort the bundle in chronological order or correlate with subtitle / chapter markers.
Frame decoding is fast — typically 20-30% of source duration. A 5-minute WebM -> PNG bundle finishes in about 1 minute regardless of how many frames you pick, because the bottleneck is the PNG encoder writing many small files in parallel, not the WebM demuxer.
Can I extract frames at exact timestamps inside the WebM video?
+
Yes — the advanced timestamp option accepts a comma-separated list (e.g. `00:01:23, 00:05:00, 00:10:42.5`) and produces one PNG file per timestamp. Useful for chapter thumbnails, scene reference shots, or building a contact sheet for review.
Is my WebM private during frame extraction?

Can the converter pick one frame per scene change in the WebM?
+
Not in the basic flow — use the "1 per second" preset as a rough approximation and visually skim the bundle for scene changes. A dedicated scene-detect extractor (powered by ffmpeg select=gt(scene)) is on the roadmap and will land for PNG export later this quarter.
Can I use the extracted PNG frames commercially?
