X (Twitter) Header Resizer - Fit Any Image to 1500 × 500

Resize Any Photo to the X (Twitter) Header Size

The X (Twitter) header size is 1500 × 500 pixels, a wide 3:1 banner that stretches across the top of your profile. Any image at a different ratio gets cropped automatically, and the part you cared about is often the part that disappears. This tool crops any photo to that exact size — and to the other X placements too — so your banner, avatar, and shared links look deliberate instead of accidental.

Everything runs in your browser. Your image is cropped locally on a canvas and downloaded straight 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 Make a Twitter Header the Right Size

1

Pick the X Size

Header Photo is selected by default. Switch to Profile Picture, In-Stream Image, or Card Image any time — the crop frame snaps 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 inside the 3:1 frame.

4

Download

Export as PNG for the crispest edges or JPG for a smaller file, already sized at 1500 × 500.

Mind the safe zone. Your circular profile picture sits over the lower-left of the header, and mobile trims the outer edges — keep logos and text centered in the top two-thirds.

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.

Where is the header safe zone?

Your circular profile picture covers a patch in the lower-left, and on phones the outer edges are trimmed. Treat the centered top two-thirds as the safe zone and place logos, text, and faces there so nothing important gets hidden or cropped.

Why does my Twitter header look cropped or blurry?

X forces every header into the 3:1 shape, so an image at a different ratio gets cut to fit. Resize it to exactly 1500 × 500 first — matching the dimensions before you upload prevents automatic cropping and the softness that comes from X rescaling an odd-sized file.

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 mask.

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).
