About Sneak Peek Lite – Thumbnail Preview

Sneak Peek Lite lets creators preview and compare up to two custom YouTube thumbnails directly on the YouTube homepage. This extension allows you to temporarily replace thumbnails on YouTube for visual comparison and inspiration. Thumbnails are not uploaded, stored, tracked, or shared. All previews are local and disappear when the page reloads. Sneak Peek Lite is designed for creators who want a fast, lightweight way to evaluate thumbnail clarity, contrast, and visibility before publishing. This Lite version does not require an account and does not collect or save any personal data.
