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

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

Resize photos without the mess
Scale an image down for sharing or up to a target size while keeping the ratio you chose.

Custom canvas size

Simple controls
Pinch, drag, and preview before you save. What you see is what gets exported.

Works offline
Your photos stay on your phone. Resize and crop without an account.

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.
