Common Aspect Ratios and When to Use Them

• •1:1 Square — Instagram posts, profile pictures, product thumbnails
• •4:3 — Standard photo print, presentations, older video format
• •16:9 — YouTube thumbnails, widescreen video, desktop wallpapers
• •3:4 — Portrait orientation, tall social media posts
• •9:16 — Instagram/TikTok Stories, vertical video
• •Free — Any custom crop for banners, headers, or specific dimensions

Why Crop vs. Resize?

• •Cropping removes parts of the image — it changes composition and pixel count
• •Resizing keeps all content but changes the pixel dimensions
• •For social media: crop first to get the right composition, then resize if needed
• •For product photos: remove background first, then crop and resize

Frequently Asked Questions

Can I crop to exact pixel dimensions?

Yes — drag the crop box to approximate dimensions, then use the Image Resizer afterward to set exact pixel dimensions.

Is there a size limit?

You can upload images up to 20 MB in JPEG, PNG, WebP, BMP, or GIF format.

Is the cropping done on the server?

No — cropping uses the browser Canvas API entirely. Your image never leaves your device.
