Why Thumbnails Matter

A compelling thumbnail can increase click-through rates by up to 154%. It is the first impression viewers get of your content.

Custom thumbnails with consistent text overlays and styling help build a recognizable brand across video platforms.

Videos with custom thumbnails get more views and longer watch times compared to auto-generated ones.

Your video is processed entirely in your browser - nothing is uploaded to any server

Frames are extracted at even intervals throughout the video using HTML5 canvas

Add text overlays with customizable position, size, and color with a contrasting shadow

Choose from common aspect ratios (16:9, 9:16, 1:1) or keep the original dimensions
