Choose a total image count or a time interval. This is sampling, not automatic slide detection. The video stays in this tab and is never uploaded.
How to use it
1. Choose a local video. MP4, WebM and MOV files work as long as your browser can play them.
2. Pick Total images, which spreads 2 to 120 images from the first second to the last, or Time interval, which takes one image every few seconds.
3. Extract, look over the grid, remove the images you don’t need and save the ZIP.
Count or interval?
A count gives you an overview. Twelve images of a two-hour film are twelve evenly spaced moments, whatever the film’s length. An interval is for when the spacing itself matters, such as one image every five seconds to check a time-lapse.
Interval mode stops at 240 images. A 30-minute video at five seconds needs 360, so the last ten minutes would be missing. Widen the interval to eight seconds, which gives 225 images, or extract the video in two parts.
What is in the ZIP
Each image is a JPEG up to 1600 pixels wide. A 1080p video gives 1600 × 900 images, and a narrower video keeps its own size. The files are named by position and time, such as frame-07-03m25s.jpg, so they sort in viewing order when you unzip them.
If you need one exact still at full size, or a PNG, the Video frame extractor captures the frame you pause on.
Why many images look the same
Sampling takes a picture at fixed times, whether or not anything changed. In a lecture where one slide stays up for two minutes, every image from those two minutes shows the same slide. If the slides are what you want, MP4 to PowerPoint keeps one image per slide instead.
Which tool fits the job
| You want | Use | You get |
|---|
| Images spread evenly over a whole video | Video to images | 2–120 images by count, or up to 240 by interval, in a ZIP |
| One exact still, such as a thumbnail | Video frame extractor | A PNG, JPEG or WebP at the video’s full size |
| Every frame across a short stretch | Video frame extractor | Up to 240 full-size JPEGs in a ZIP |
| The slides from a lecture or meeting | MP4 to PowerPoint | One image per slide, as PPTX or PDF |
- How many images can I extract?
- Count mode offers 2 to 120 images. Interval mode keeps at most 240, so a short interval may not cover a long video. This tool is free and needs no account.
- What format and size are the images?
- They are JPEGs up to 1600 pixels wide, in a single ZIP. For a full-size PNG of one moment, use the Video frame extractor.
- Can it pick out only the frames with slides?
- No. This page samples by time, so it cannot tell one slide from the next. MP4 to PowerPoint detects each new slide and keeps one image of it.
- Is my video uploaded?
- No. Your browser opens the file in this tab and makes the images on your computer. Nothing is sent to our server.
- Why won’t my video open?
- The tool reads only what your browser can play. HEVC and ProRes files do not play in every browser; if yours is refused or stays black, convert it to H.264 MP4 and try again.
