Common questions

Where do the sizes come from?

From each platform's own help pages, read on 9 October 2026, where they give a size: the Instagram Help Center (photos up to 1080 pixels wide, shapes from 1.91:1 to 4:5), Facebook Help (cover photo 851 by 315), X Help (header 1500 by 500, profile photo 400 by 400), LinkedIn Help (page post image 1200 by 627, page cover 1512 by 256), YouTube Help (thumbnails 16:9, at least 640 pixels wide) and Meta for Developers (link previews at least 1200 by 630). Where a platform gives only a shape, the size most widely used for it is used: 1080 by 1920 for 9:16 stories, 1000 by 1500 for 2:3 pins, 1584 by 396 for a LinkedIn profile background, 2560 by 1440 for a YouTube banner and 1600 by 900 for a 16:9 X post.

What size is an Instagram post?

1080 pixels wide: 1080 by 1080 for square, 1080 by 1350 for portrait (4:5) and 1080 by 566 for landscape (1.91:1). Stories and reels are 1080 by 1920.

Will my image be cropped?

With Fill the size it is, wherever the shape differs from yours; click the image to choose the point kept in view. Choose Show it all to fit the whole image inside each size on a blurred or plain background instead.

Why does a card say Enlarged?

Your image has fewer pixels than that size needs, so it was scaled up and may look soft. Use a larger original for those sizes if you can.

Which format should I save in?

JPG for photos, which keeps files small for upload. PNG for designs with text or flat colour, which stays crisp. WebP is smaller still where the platform accepts it.

Is my image uploaded?

No. It is resized by code running in your browser and never leaves your device.

Can I resize several images at once?

This tool takes one image and makes every size from it. For many images at one size, use the Image Resizer.

Is it free?

Yes, completely free, with no sign-up and no watermark.
