Frequently Asked Questions
How do I crop an image to 16:9?
Upload the image, choose 16:9 from the Aspect Ratio list and click Crop. The largest centred 16:9 area of your photo is kept.
What aspect ratios are available?
16:9 (widescreen), 4:3 (classic screens and slides), 1:1 (square), 3:2 (35 mm photo prints) and 21:9 (ultrawide/cinematic).
What is an aspect ratio?
It is the proportion of width to height. 16:9 means 16 units wide for every 9 units tall, whatever the actual pixel size.
Which part of the image is kept?
The crop is centred, so the middle of your photo is kept and equal amounts are trimmed from opposite edges.
What aspect ratio is a YouTube thumbnail?
YouTube thumbnails are 16:9, ideally 1280×720 px. The YouTube Thumbnail Resizer crops and resizes to that exact size in one step.
What ratio is best for printing photos?
3:2 matches standard 4×6 inch prints; 4:3 suits 6×8 inch prints.
Does cropping to a ratio change the resolution?
It removes pixels from the edges but doesn’t scale the image, so what’s kept is at full original quality.
Can I crop a portrait photo to 16:9?
Yes, but a lot of the top and bottom will be removed. Make sure your subject is near the centre of the picture.
How do I crop to an exact pixel size as well?
Crop to the ratio here, then use Resize Image by Pixels to reach the exact dimensions.
Does the Crop to Aspect Ratio tool store my images?
No. Cropping happens in memory and the file is discarded right away.
