How to make a YouTube thumbnail
Add a picture
Choose a screenshot, or open your recording and pick the exact frame you want.
Write a headline
Pick a template and write a few words. The text resizes to fill its box.
Point at what matters
Add arrows and highlights, crop in on the result, and add a picture of yourself if you like.
Download and check
Download a JPEG or PNG, then compare it with your title in the thumbnail preview.
Made for software tutorials
Most thumbnail makers start from a stock template. This one starts from your own screen, because a tutorial’s best picture is usually the result the viewer is about to build. Open a recording, step through it one frame at a time, and use the frame that shows the finished chart, the working page or the setting people are looking for.
A whole app window rarely survives being shrunk to a feed card. Zoom into the part that matters, put a highlight around it and let an arrow do the pointing. You can darken everything outside a highlight, so one panel stands out from a busy interface. The small preview under the editor shows the thumbnail at feed size as you work.
What size should a YouTube thumbnail be?
YouTube recommends 3840 × 2160 pixels for video thumbnails, in a 16:9 shape, and needs a width of at least 640 pixels. JPG and PNG both work. The file limit depends on where you upload from: 2 MB on a phone and 50 MB on a computer. These details were checked on 5 November 2026.
This tool downloads 1920 × 1080 by default, which stays sharp and is usually well under 2 MB as a JPEG. Choose 3840 × 2160 if your screenshot is large enough to fill it. A bigger size adds nothing if the picture has to be enlarged, and the tool tells you when that happens. If a file goes over your maximum, JPEG quality is lowered in steps until it fits, and the download message says what quality was used.
Write a headline that reads at feed size
Thumbnails are often seen about 170 pixels wide, so the headline needs to be short. Three to five words usually work. Say the outcome rather than repeating your title: if the title is “How to build a sales dashboard in Google Sheets”, the thumbnail can say “Sales dashboard in 10 minutes”.
Headlines can be up to 80 characters, but the page warns you well before that. If the text has to shrink too far to fit its box, you get a note to use fewer words. If it still does not fit, it is cut with an ellipsis and you are told. YouTube draws the video length over the bottom right corner, so the guides mark that corner and the page warns you if the headline runs into it.
Keep your thumbnails looking like a series
Viewers spot a channel by its repeated look. Set a bar color and an accent color, pick a template, then save them as a brand. The next time you open this page, choose the brand and your colors and template are back. You can save up to eight, and delete any of them at any time.
Brands are kept in this browser’s own storage. They hold only the two colors, the template and the name you gave them. Your pictures and headlines are not saved, and clearing your browser data removes the brands too.

Get a better frame from your recording
A good thumbnail is easier when the recording has a clean moment to use. Before you stop recording, hold the finished result on screen for a few seconds, with notifications off and the window at a sensible size. Rescreen’s browser screen recorder captures your screen and voice, and the end screen template can finish the video in the same colors. To find the sharpest moment first, the extract frames tool saves any frame of a video as a full-size image.
Frequently asked questions
Do I need an account or a design tool?
No. The tool is free, needs no account and puts no watermark on your thumbnail.
Does it use AI to make the picture?
No. Every thumbnail is built from your own screenshot or video frame, so it shows what the video really contains.
Which video files can I pick a frame from?
MP4, MOV, WebM and MKV, as long as your browser can decode the video inside. Long recordings are fine, because the page reads only the part of the file it needs. If a format will not open, take a screenshot of the frame and add that instead.
Is the frame exactly the one I chose?
Yes. The page shows the time of the frame it decoded, and that is the frame you get. Use Previous frame and Next frame to step through one at a time, or type a time to jump to it.
Can I use the keyboard?
Yes. Choose an element in the Element list and use its sliders, or select the preview and use the arrow keys. Hold Shift to move further, and press Delete to remove the element. Ctrl or Command with Z undoes a change.
Which fonts does it use?
Headlines use Bricolage Grotesque, an open font hosted on this site, so you can use the thumbnail freely. Characters outside the Latin alphabet use your device’s own font.
What happens to my files?
They stay in your browser, and so does your headline. Images can be JPEG, PNG or WebP, up to 30 MB and 40 megapixels, and at least 320 × 180. Very large pictures are scaled down to 4096 pixels on the long side while you work.
