Resizing one image into nine different aspect ratios by hand is busywork. Auto Social Crop uses subject-detection to keep your subject framed correctly across all 9 standard social-media sizes — Instagram (4 sizes), TikTok, Twitter/X, Facebook cover, LinkedIn (2), YouTube thumbnail.

The 9 sizes you get

Subject detection means clean crops

Most resizers just centre-crop. Ours finds the main subject (person, face, object) and crops around them — so a tall portrait doesn't become a YouTube thumbnail of someone's shoes.

Frequently asked questions

Can I add my logo / watermark in one batch?

Yes — premium users get a 'brand kit' option. Upload your logo once; it stamps in the corner of every output.

What if I want a custom size not on the list?

Use the standalone Aspect Ratio Crop tool. Auto Social Crop is preset to the 9 standard platform sizes.
