1280 by 720, the HD sixteen by nine frame
You need a 720p sized image, usually for a video thumbnail or a widescreen slide.
1280 by 720 is high definition at its most widely supported resolution and the minimum recommended size for a video thumbnail on most platforms. The sixteen by nine shape matches modern screens, so the image fills a display without black bars. It is also the safe choice for presentation slides, because projectors and conference room displays are overwhelmingly widescreen and a four by three slide is letterboxed on them.
When people use this tool
Video thumbnails
Platforms display thumbnails at many sizes, and 1280 by 720 is the baseline that stays sharp at all of them.
Presentation slides
Widescreen decks fill a projector or meeting room screen edge to edge.
Blog headers
A 16:9 header sits well above an article without pushing the text too far down the page.
Step-by-step
- 1 Upload the image. The file is read locally and never uploaded.
- 2 The HD frame is applied. Your picture is fitted into 1280 by 720 with its proportions preserved.
- 3 Check the composition. Thumbnails are viewed small, so a single clear subject works far better than a busy scene.
- 4 Download. The result is exactly 1280 pixels wide and 720 tall.

Practical tips
- • Faces and large text perform best in thumbnails because they remain legible at small sizes.
- • Keep the corners clear, since duration badges and interface overlays sit there.
- • If you need the highest quality, 1920 by 1080 uses the same ratio and scales down cleanly.
- • Compress the finished thumbnail so it uploads reliably on a slow connection.
More questions about this tool
Is 1280 by 720 the same as 720p?
Yes. 720p refers to 720 lines of vertical resolution in a 16:9 frame.
Should a thumbnail be 720p or 1080p?
Either works. Larger gives more headroom, but 1280 by 720 is the minimum most platforms recommend.
Why does my 4:3 photo have bars?
It is fitted inside the wider frame, so space appears at the sides rather than the sides being cut off.
What file size should a thumbnail be?
Well under 2 MB. A few hundred kilobytes is normally plenty at this resolution.
