Why People Use PixDuplicate's Thumbnail Generator

Grab the Exact Frame

Scrub through the video with the player controls and pull the frame you're looking at. No guessing at timestamps—just stop where you want and grab it.

Two Ways to Batch

Pick a number of thumbnails to spread evenly across a range, or set an interval so one gets pulled every X seconds. Count mode for a set, interval for a storyboard.

Extract a Whole Set

Pull multiple thumbnails in one pass with the same settings. Useful when you're building out a preview gallery or storyboarding a video.

Nothing Gets Uploaded

Everything runs in your browser. Your video never leaves your device—no servers, no cloud.

Download Everything at Once

Grab the whole batch as a ZIP so you're not downloading them one at a time. Or pick just the ones you want and download those individually.

Resize the Output

Keep the original resolution or set custom dimensions. Aspect ratio lock keeps things from stretching. Handy when you need thumbnails at a specific size for a platform.

How the Thumbnail Generator Works

Pulling frames from video—without sending anything anywhere

Step 1: Add your video

Drag and drop a file or try the example. Supports MP4, WebM, MOV, AVI, and most other formats that play in a browser, up to 2GB.

Try the example video first if you just want to see how the extraction works before uploading anything of your own.

Step 2: Pick your approach

A few ways to go about it:

Set a time range if you only want thumbnails from part of the video

Pick a mode: single frame, a specific count spread across the range, or intervals of X seconds

For a single frame, scrub to the exact spot and hit extract

Or just grab whatever frame the player is currently showing

Step 3: Set the output

How you want the thumbnails saved:

Format: PNG (lossless), JPEG (smaller), or WebP (modern)

Quality: for JPEG and WebP, slide it up or down

Dimensions: keep original size or set custom width and height

Single or batch: extract one frame, or process a whole set

Step 4: Grab your thumbnails

Once done:

Look through the results gallery to check each thumbnail

Select individual ones if you only want a few

Download selected files individually or grab the whole batch

ZIP export when you've got a full set to save

Tip: For a storyboard, use interval mode with something like every 5 seconds. You get a consistent spread of frames without thinking about how many you need. Count mode is better when you want an exact number.

Your video never leaves your device

No uploads, no cloud processing

No sign-up or personal info needed

Rowan Delacroix

"Solid for YouTube thumbnails. I scrub to the exact second I want, extract, done. The batch mode is nice for pulling a handful of options when I'm not sure which frame looks best. Would be 5 stars if it saved my custom dimensions between sessions."

Ingrid Voss

"Used this to build a storyboard for a client's explainer video. Interval mode with every 3 seconds gave me 60 frames across the whole thing. Downloaded as a ZIP, dropped them into a doc, annotated each one. Would've taken an hour in Premiere—took maybe ten minutes total."

Malachi Foster

"Works fine for pulling single frames but batch extraction on a long 4K video gets slow. My laptop fans spun up. Fine for 1080p stuff. The one-click 'extract current frame' button is the feature I use most—wish it were more prominent."

Corinna Vasquez

"I run social for a restaurant chain and pull thumbnails from food prep videos every week. The output quality at PNG is identical to the source. Nothing gets uploaded, which matters since the videos aren't public until the campaign goes live."

Desmond Kane

"The custom dimensions feature is what makes this useful for me—I need 1280×720 thumbnails for YouTube and the aspect ratio lock keeps me from accidentally stretching things. Batch extraction with a specific count is how I generate a week's worth of options at once."

Selene Abernathy

"Does exactly what it says. I pull reference frames for illustration work—grab a few angles of something, use them as guides. No complaint with the tool itself, just wish my 8-year-old laptop were faster at processing. Would recommend regardless."

Common Questions

What video formats can I use?

MP4, WebM, MOV, AVI, and most other formats that a modern browser can play. The extraction is done through the browser's built-in video decoder, so if the video plays in your browser, it works here.

How exact is the timestamp?

Frame-accurate. Scrub to the moment you want with the player controls, or type in an exact timestamp. The extracted image is the frame at that exact time—no drifting a few frames off.

Is there a file size or length limit?

Up to 2GB per video. No strict length limit, but very long videos with lots of thumbnails extracted can slow your browser down. Under 100 thumbnails per batch tends to be smooth.

Are my videos private?

Yes. Everything runs locally in your browser using the HTML5 Canvas API. Your video never gets uploaded anywhere. Matters if the video isn't public yet.

Can I extract at regular intervals?

Yes. Set a start and end time, then pick either count mode (a specific number spread evenly) or interval mode (every X seconds). Interval mode is what you want for storyboards. Count mode when you need exactly N thumbnails.

What output formats are supported?

PNG (lossless, larger files), JPEG (smaller, lossy), or WebP (modern, efficient). For JPEG and WebP you can set the quality slider to balance size against clarity.

Can I resize the thumbnails?

Yes. Keep the original video dimensions or set custom width and height. Aspect ratio lock prevents stretching. Useful when a platform needs thumbnails at a specific size.

Why would I need to pull thumbnails?

YouTube previews, social media posts, storyboarding, contact sheets for a video library, reference frames for design work, or grabbing a still from a video for documentation. Lots of reasons.

Count mode vs. interval mode—what's the difference?

Count mode: pick 10 and you get 10 evenly spread across the range. Interval mode: pick 'every 5 seconds' and you get however many fit in the range. Count is good when you need a specific set size. Interval is good when consistent spacing matters more than the total.

Does it work on phones?

Runs in any modern browser, so yes. But pulling a lot of thumbnails from a high-resolution video is faster on a desktop with more processing power.
