Free X (Twitter) Image Resizer

What is a X image resizer?

A X image resizer cuts a photo to the exact pixel sizes X uses, so nothing gets cropped or blurred when you upload it.

This one has every X size in one place. It makes each file at a high quality and keeps it under X's upload limit.

Every X image size in 2026

Here are all eight sizes:

The resizer has every size in this table. Pick the ones you need, and each becomes its own file.

Tips for X images

A few sizes come with rules worth knowing:

• Header – Some screens crop about 60 px from the top and bottom, so keep text in the middle.

The resizer draws the safe areas and round crops on each preview, so you see them before you download.

X upload rules

Here's what X accepts:

• Formats – JPEG, PNG, GIF, WEBP.
• File limits – 2 MB, 5 MB, depending on where the image goes.
• Per post – up to 4 photos.

When a file comes out over a size's limit, the resizer makes it again at the best quality that fits, the same size.

Examples

This is my own photo of Stockholm at sunset, over Fotografiska, cut to four X sizes by this resizer:

I kept the sunset in every crop, the part of the photo that matters most.

Compared with Buffer

Buffer's free image resizer has a page for most networks. I ran the same photos through both on October 1, 2026:

On the same photos, cut to LinkedIn, Instagram, Pinterest and YouTube sizes, this resizer's JPGs scored within about a point of Buffer's and were 13% to 24% smaller.

The first crop matters too. On my Panama City photo, Buffer's LinkedIn cover started on the houses below the sunset, and this resizer's started on the sunset.

How I tested

I tested on October 1, 2026, with two of my own photos, Stockholm and Panama City at sunset, 1,536 × 2,048 each.

Above 80 means the same side by side at 100%. Both tools' files scored 85 to 88 where both cut the same area.

Where these sizes come from

Every size on this page is from X's own pages, checked on October 1, 2026:

• X Business: Ads creative specs
• X Help: Help with uploading a profile photo
• X Help: How to post photos or GIFs

When a page gives a range instead of one size, I picked the sharpest size inside it and said so in the tips.

Who is the X image resizer for?

It's for anyone posting on X:

• X character counter – people writing posts to the limit
• Post image generator – anyone turning a post into an image
• Remove background – people making a clean profile photo
• Compress image – anyone making a photo smaller first

Social media managers use it to make every X size from one photo in a minute.
