Aspect Ratio & Canvas Resizer

Ever cropped a photo, then watched Instagram or YouTube stretch it anyway? This app is for that exact headache.

Photo Resizer lets you crop and resize any picture to a real aspect ratio — 1:1, 4:5, 9:16, 16:9, 3:2, 4:3, and custom sizes — so the photo you save is the photo people actually see. Pick a photo, choose a ratio, move the crop, and export. No extra steps, no watermark in the way.

Use it when you need a photo to fit a specific canvas:

• Instagram posts, stories, and reels
• YouTube thumbnails and channel art
• Facebook, WhatsApp, Pinterest, and LinkedIn
• Print sizes, profile pictures, and website banners
• Any custom width and height you type in

What you can do

Lock 1:1, 4:5, 9:16, 16:9, and other common ratios so nothing gets stretched.

Who it’s for
Creators posting every day, small business owners making product shots, students submitting photos in a required size, and anyone tired of “this image doesn’t match the recommended ratio.”

If you have been hunting for a photo resizer, image cropper, or aspect ratio tool that just does the job, try this one. Open a photo, pick the ratio, save it, and move on with your day.
