Settings guide

Aspect ratios for common use cases:

  • ·1:1 (square): Instagram feed posts, profile photos on all platforms
  • ·4:5 (portrait): Instagram portrait posts — takes more feed space than 1:1, increases visibility
  • ·16:9 (landscape): YouTube thumbnails, Twitter/X posts, LinkedIn posts, desktop wallpapers
  • ·9:16 (tall portrait): Instagram Stories, TikTok, Reels, YouTube Shorts, WhatsApp Status
  • ·4:3: Standard photography, older monitor formats, certain presentation slides
  • ·Freeform: Crop to any custom dimensions for specific use cases

Format comparison

Cropping vs resizing: Cropping removes parts of the image (reduces canvas area). Resizing changes the total pixel dimensions of the whole image. For social media, you usually need to crop first (correct aspect ratio), then resize (correct pixel dimensions).

Preset ratio vs pixel crop: Preset ratios maintain the correct proportions for platforms. Pixel crops let you specify exact output dimensions. For social media, use preset ratios; for specific design requirements, use pixel mode.

About this format

When you upload an image to a platform with the wrong aspect ratio, the platform makes the decision for you — and it's rarely the one you'd make yourself. Instagram crops your portrait photo from the centre. YouTube letterboxes your thumbnail with black bars. LinkedIn stretches your post image to fit its container.

Understanding aspect ratios turns cropping from trial-and-error into a deliberate decision. A 16:9 image has 1.78 units of width for every unit of height — that's why YouTube thumbnails and HD video frames look the way they do. A 1:1 image is a perfect square. A 9:16 image is the tall portrait format of Stories and Reels.

This cropper lets you select a preset ratio, drag to position the crop, and download exactly what you intended. Everything runs in your browser.

Frequently asked questions

What aspect ratio should I use for YouTube thumbnails?+
16:9 — specifically 1280×720px at minimum, 1920×1080px recommended. YouTube displays thumbnails at various sizes but always in 16:9 ratio. An image with the wrong ratio gets letterboxed with black bars.
What aspect ratio should I use for Instagram posts vs Stories?+
Posts: 1:1 (square, 1080×1080px) or 4:5 (portrait, 1080×1350px) for maximum feed space. Stories and Reels: 9:16 (1080×1920px). Using the wrong ratio results in Instagram cropping your image automatically, often badly.
How do I crop to an exact pixel size?+
Switch from ratio mode to pixel mode in the tool. Enter your exact target width and height. The crop area will snap to those proportions.
Does cropping reduce image quality?+
No. Cropping removes pixels at the edges but does not change the quality of the remaining pixels. The cropped area retains full original quality.
What is the difference between cropping and resizing?+
Cropping removes parts of the image (reduces canvas area). Resizing changes the total pixel dimensions of the whole image (scales it up or down). For social media, you usually need to crop first (correct aspect ratio), then resize (correct pixel dimensions).
Are my files uploaded to a server?+
No. Runs in your browser.
