X (Twitter) Image Resizer

X (formerly Twitter) shows your images in several shapes at once — a wide 3:1 header across your profile, a circular profile photo, and link-preview cards in the timeline. Each one expects its own pixel dimensions, and an image at the wrong ratio gets cropped automatically, often hiding the part you wanted seen. This tool resizes and crops any image to a confirmed X size so your profile and shared links look clean and deliberate.

Everything runs in your browser. Your image is cropped locally on a canvas and downloaded back to you — nothing is uploaded anywhere.

X (Twitter) Sizes You Can Create

Header Photo

1500 × 500 px — the wide 3:1 banner at the top of your profile.

Profile Picture

400 × 400 px — uploaded square, displayed in a circle.

In-Stream Image

1600 × 900 px — a 16:9 photo attached directly to a post.

Card Image

1200 × 628 px — the link-preview card shown when you share a URL.

How to Resize an Image for X (Twitter)

1

Pick the X Size

Choose a preset — Header Photo, Profile Picture, In-Stream Image, or Card Image. The crop frame switches to that exact aspect ratio.

2

Upload Your Image

Click the upload area or drag and drop a file. JPG, PNG, and WebP are supported.

3

Position & Zoom

Drag to reposition the image, then scroll the wheel, use the zoom buttons, or pinch on mobile to control exactly what stays in frame.

4

Download

Export as PNG for the crispest edges or JPG for a smaller file, already at the exact X dimensions.

Your photo overlaps the header. The circular profile picture sits over the lower-left of the header, so keep key text and logos toward the center or right.

Frequently Asked Questions

What size is the X (Twitter) header?

The header photo is 1500 × 500 pixels, a wide 3:1 ratio. Because it is so wide and short, keep important content horizontal and away from the lower-left, where your profile picture overlaps it.

What is a Twitter Card image?

Card images are the previews that appear when you share a link in a post. The recommended size is 1200 × 628 pixels, which keeps the preview crisp and fully visible in the timeline.

What size should my profile picture be?

Use a 400 × 400 pixel square. X displays it as a circle, so center your subject and leave the corners free, since they get cropped off in the circular crop.

Are my images uploaded to a server?

No. All cropping happens in your browser on a local canvas. Your images never leave your device, so the tool is safe for private or unpublished images.

Which file formats can I use?

Upload JPG, PNG, or WebP. Download the cropped result as a PNG (lossless, best for graphics and text) or a JPG (smaller file, best for photos).
