WebM to PNG Optimization FAQ
How do I extract frames from a WebM video as PNG images?
+
Upload the WebM and open the options. Frame Extraction has two modes: Single Frame saves one PNG from the second you enter (for example 1, 5 or 10.5), and All Frames saves every frame of the video as a PNG image. There is no every-Nth-frame or one-per-second mode.
At what resolution does the extracted PNG image come out?
+
Same pixel dimensions as the source WebM — a 1080p video produces 1920x1080 PNG frames, a 4K source produces 3840x2160 PNG frames. Resize after extraction if you need smaller thumbnails (we have a /image-resize/ tool for that).
Can I extract every frame from a WebM file as PNG?
+
Yes, with All Frames in the Frame Extraction option, but watch the count: one minute of 30 fps video gives 1,800 PNG images. For a single still, choose Single Frame and enter the second you want instead.
Will the PNG images preserve WebM HDR color?
+
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 a PNG. Standard (SDR) video keeps its colours.
How long does frame extraction from WebM to PNG 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 a PNG. There is no field for a list of times, so run the conversion again for each extra timestamp.
Is my WebM video private during PNG 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 PNG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Why are my extracted PNG frames blurry?
+
Almost always motion blur from the source WebM — the camera was moving when the frame was captured. Try picking timestamps from static scenes, or extract several adjacent frames and choose the sharpest. The pipeline does not synthesize sharpness.
Does this tool support one-frame-per-scene-change extraction?
+
No. The converter has no scene detection and no one-per-second mode: it saves either a single frame at the second you enter or every frame. For one image per scene, extract single frames at the times where the scenes change.
Can I use the extracted PNG frames commercially?
+
Yes, subject to whatever licence governs the source WebM content. The format change adds no claim — we apply no watermark, embed no tracking, and claim no licence on the PNG output.
