Twitter/X Header Size: Resize to 1500 × 500

The header is the wide banner at the top of an X (Twitter) profile. X recommends an image of 1500 × 500 pixels, a 3:1 ratio, and displays it across desktop and mobile with the profile picture overlapping the lower left. A badly sized upload gets scaled and cropped unpredictably.

This resizer turns any image into an exact 1500 × 500 pixel header. It uses Crop to fill, so the banner is filled completely and the top and bottom of taller images are trimmed; choose which part to keep with the position setting. The file keeps its format unless you choose JPG, PNG or WebP.

How to use the Twitter/X Header Resizer (1500 × 500)

1. Drop your images onto the upload area, click it to choose files, or paste an image with Ctrl+V. This page accepts JPG, PNG, WebP, GIF and BMP files, many at once and up to 80 MB each.
2. Keep 1500 × 500 and choose the crop position: Center for most images, Top or Bottom if the subject sits higher or lower.
3. Keep important text and faces away from the lower left corner and the outer edges, where the profile picture and mobile cropping can cover them.
4. Check the result with the before/after slider: drag the divider across the preview and read the new dimensions, file size, quality and percentage saved underneath. Any change to the settings re-processes every image automatically.
5. Download a single image, or use Download all (ZIP) for the whole batch. Under More options you can also set a DPI value and a file-name pattern with {name}, {w} and {h}.

Header design tips

• Leave a safe area. Mobile apps crop the sides slightly, so keep key content in the middle third.
• Use a wide image. Landscape photos and panoramas work better than portraits for a 3:1 banner.
• Keep it light. Headers under about 2 MB upload quickly; JPG at quality 85 to 90 is usually ideal.
• Same size elsewhere. The fixed size page 1500×500 and other banners such as the LinkedIn banner are available too.

Making a header from a photo

Panoramas and wide landscape shots work best. With a normal 4:3 or 3:2 photo, the 3:1 crop keeps only about half of the height, so choose the crop position carefully: Top for skylines and mountains, Center for groups and objects. If your photo is too tall, Fit with background adds side areas instead of cropping, which can look intentional with a matching colour.

Platforms change their layouts from time to time, so check how the header looks on both desktop and phone after uploading.

Private, free and fast

The whole job runs in your browser: images are decoded, resized and re-encoded on your own device, so nothing is uploaded to a server. There is no sign-up, no watermark and no daily limit, and location and camera data (EXIF) are removed from every result.
