Why export a video frame as PNG?
PNG avoids an additional lossy image encode after your browser decodes the video. It is useful for screen-recording text, UI screenshots, editing references and computer-vision review. A PNG cannot undo video compression, source blur, lost detail or decoding color changes. Native-size output describes dimensions, not restoration or byte-identical video data.
Capture a still or a PNG sequence
Choose a local video and wait for a playable preview. Enter seconds or a clock timestamp, inspect the result and capture the current picture. For several stills, enter a range with an exclusive end and choose intervals, an evenly spaced count or requested timestamps. A 2–5 second range with a one-second interval requests pictures at 2, 3 and 4 seconds. Browser seeking is not guaranteed to select an exact source-frame index.
Resolution and memory
The canvas uses decoded dimensions, up to 8.3 million pixels per picture. A compatible 3840 × 2160 source can produce a 3840 × 2160 PNG. The gallery retains no more than 120 pictures or 96 MB, whichever comes first. Detailed PNGs can reach the byte limit quickly. Download individual PNGs or a ZIP, and clear the gallery between ranges. For smaller review files try JPG; for one overview image create a contact sheet.
Practical expectations
The extractor uses your browser decoder and canvas without an AI model or FFmpeg download. Selected media is not uploaded for extraction. MP4, MOV and WebM playback depends on the contained codec and browser. HDR, wide-gamut color and orientation handling can vary; inspect the exported picture before using it as a reference.
