Frequently asked questions
What is the YouTube thumbnail size?
A YouTube thumbnail is 1280×720 px (16:9 aspect ratio) with a minimum width of 640 px, kept under 2 MB as JPG/PNG. Resize to 1280×720 with TryQuickImg, then compress if needed — all in your browser.
How do I resize my image for YouTube without losing quality?
Resize to the exact pixels (1280×720) rather than cropping randomly, and start from the highest-resolution original you have. TryQuickImg draws the resized copy on a canvas in your browser, so there is no re-upload and no quality-stealing server round-trip.
Is my photo uploaded to TryQuickImg?
No. TryQuickImg runs in your browser. After the page loads you can go offline and still resize — nothing is posted to a server.
