Circular crop

Crop an image into a circle with transparent corners

For a circular profile picture, select a square format and set “Shape” to “Circle.” The result is a circular crop you can upload directly as an avatar.

  • “Circle” is available for all square formats: “Square” (1:1), Discord, YouTube, X, Instagram, and TikTok profile pictures, Discord server icons, and square Instagram posts.
  • With PNG or WebP, everything outside the circle stays transparent. JPG does not support transparency, so the selected background color fills the corners.
  • For profile pictures that the platform displays as circles, a dashed line shows what will remain visible inside the circle.

Guides

Crop images online: good to know

Precise pixel dimensions, image quality, privacy, and what the tool intentionally doesn't do.

Crop an image to specific pixel dimensions

Under “Crop,” enter Left (X), Top (Y), Width, and Height in pixels. With a fixed aspect ratio, the other dimension adjusts automatically. Platform formats always save at their fixed size, such as 1280 × 720 px for a YouTube thumbnail. With “Free” and aspect ratios, you can keep the crop's pixel dimensions or set a custom width under “Output size.”

Keep it sharp: when an image loses quality

If the crop is at least as large as the target size, the image will only be scaled down, if at all. If it's smaller, the tool scales it up and warns you because the result may look blurry. PNG saves without quality loss; for JPG and WebP, set the quality with a slider (default: 90%).

No upload, no GPS data in the result

Your image is opened, cropped, and saved in your browser; it is not uploaded to a server. Because a new file is created when you save it, metadata such as GPS location is not included in the result.

No Paint, Word, or Photoshop needed—even on your phone

You don't need to install any software or app. The tool runs in your browser on desktop and mobile: drag the frame with your mouse or finger, or move it with the arrow keys. Paste a screenshot directly with Ctrl+V.

Cropping does not remove backgrounds

The tool crops a rectangular or circular section of your image. It does not remove backgrounds or support freehand or lasso selections. The Sprite Sheet Cutter splits an image into equal-sized sections using rows and columns.

FAQ

Frequently asked questions about cropping images

Quick answers about cropping and image sizes.

Drag the image into the tool, select it, or paste it with Ctrl+V. Then choose “Free,” an aspect ratio, or a platform format, and move or resize the frame by dragging its corners and edges. Finally, click “Download.”

Choose a square format, such as “Square” or a profile picture, and set “Shape” to “Circle.” With PNG or WebP, the corners remain transparent; with JPG, the selected background color fills them.

The tool is free, you don't need an account, and the result has no watermark. Cropping and saving happen in your browser; the image is not uploaded. Metadata such as GPS data is removed when you save it.

Yes. Enter the crop's position (X/Y), width, and height in pixels. Platform formats save at their exact upload sizes. With “Free” and aspect ratios, you can also set a custom output width.

No, as long as the crop is at least as large as the target size. If it's smaller, the tool warns you because the image will be enlarged.

You can open JPG, PNG, WebP, GIF, and AVIF files up to 40 MB; HEIC photos only work in Safari. Save as PNG, JPG, or WebP. Formats your browser cannot create are grayed out.

The thumbnail is 1280 × 720 px. The channel banner is 2560 × 1440 px at a 16:9 aspect ratio, but only the central 1546 × 423 px is visible on all devices. Place text and logos there. The profile picture is 800 × 800 px.

Server banner 960 × 540 px (16:9, from Boost Level 2), profile banner 600 × 240 px (5:2, with Nitro), profile picture and server icon 512 × 512 px. Discord displays profile pictures as circles.

Square: 1080 × 1080 px; portrait: 1080 × 1350 px (4:5) or 1080 × 1440 px (3:4, fits the profile grid exactly); Story and Reel: 1080 × 1920 px; profile picture: 320 × 320 px.
