Upload multiple images in one go and resize them all to the same X format simultaneously. Perfect for batch-preparing a content drop or updating your full profile — header, profile photo, and post images — in one session.
All X (Twitter) Formats Pre-Set
Post image (1600×900), Header photo (1500×500), Profile photo (400×400), In-stream image (1200×675), and Card image (1200×628) — all pre-configured so you never have to look up the numbers.

Frequently Asked Questions

Everything you need to know about image resizing

Can I resize multiple X (Twitter) images at once?

Yes. You can upload up to 12 images at once and resize them all to the same X format in a single step. Ideal for batch-preparing post images, updating your profile assets, or preparing a full content drop without repeating the process for each image.

What are the correct X (Twitter) image dimensions in 2026?

X's recommended image dimensions for 2026: Post image — 1600×900 px (16:9); Header photo — 1500×500 px (3:1); Profile photo — 400×400 px (1:1); In-stream image — 1200×675 px (16:9); Card image — 1200×628 px (approximately 2:1). All of these are pre-set in this tool.

What is the best image size for an X (Twitter) post?

The recommended X post image size is 1600×900 px (16:9 aspect ratio). Images in this ratio display in full without cropping in the timeline on both desktop and mobile. A minimum of 600×335 px is required, but uploading at 1600×900 gives sharper results on retina displays.

What size should my X (Twitter) header photo be?

The X header (banner) photo should be 1500×500 px (3:1 ratio). The file size limit is 5 MB for JPG or PNG. Keep key content within the central safe zone, as the header image is cropped differently on mobile vs. desktop. This tool pre-sets exactly these dimensions.

How does the tool handle images with the wrong aspect ratio?

When your image's proportions don't match the X format you selected, you have several options in the editor: Cover — fills the frame and crops the edges (no blank space); Contain — fits the entire image inside the frame with letterbox/pillarbox padding; Stretch — distorts the image to fill the frame exactly; Crop — lets you manually select which region to keep. Cover is the most common choice for a clean, full-frame look.

What is the difference between an X post image and a card image?

An X post image (1600×900 px, 16:9) is the direct image attached to a tweet. A card image (1200×628 px) is used for link previews — the image pulled automatically from a web page's Open Graph tags when you share a URL. If you control the website being shared, use the card image size for your OG image. This tool has both sizes pre-set.

Why does my X header photo look blurry or get cropped?

Header photos look blurry when the uploaded image is too small — X stretches it to fit the 1500×500 px frame. They get cropped unexpectedly when key content is placed near the edges, which are hidden on mobile. The fix is to upload at exactly 1500×500 px and keep text and important elements in the centre. This tool resizes your image to those exact dimensions before upload.

Is it safe to use this tool for content I haven't published yet?

Yes. All processing runs entirely in your browser — your images are never uploaded to any server. This makes it safe for preparing unreleased campaign images, sensitive profile updates, or client content before it goes live.

Should I use JPG or PNG for X (Twitter) images?

For most X post images and headers, JPG is the better choice — smaller file size and X re-compresses uploads anyway. Use PNG when your image contains text, logos, or transparent backgrounds where compression artefacts would be visible. In the editor you can choose the output format before downloading.

What image formats are supported?

You can upload JPG, JPEG, PNG, and WebP images. You can also choose the output format in the editor — for example, converting a PNG to JPG typically reduces file size significantly.

Do I need an account or login?

No. Resize images for X (Twitter) completely free — no account, no login, no watermarks. Just upload and download.
