Resize Image for Facebook (Post and Cover)
Resize any image for Facebook: shared post 1200 x 630, cover photo 851 x 315, story 1080 x 1920. One click in your browser. No upload, no watermark.
Nothing is uploaded. Your image is resized right here in your browser and never leaves your device.
Facebook image sizes
Facebook uses a different shape almost everywhere, which is why an image that looked right as a post looks wrong as a cover.
| Where | Pixels | Ratio |
|---|---|---|
| Shared post / link preview | 1200 x 630 | 1.91:1 |
| Cover photo (page or profile) | 851 x 315 | 2.7:1 |
| Profile picture | 170 x 170 | 1:1, shown as a circle |
| Story | 1080 x 1920 | 9:16 |
| Event cover | 1200 x 628 | 1.91:1 |
The two most people need are the shared post at 1200 by 630 and the cover photo at 851 by 315. Pick one in the preset, use cover to fill the frame and crop the overflow, or fit to keep the whole image with padding.
Why covers look cropped on your phone
This catches everybody. A Facebook cover is 851 by 315 on a desktop browser, but phones display a narrower slice of the same image, closer to 640 by 360.
The difference is not a scale, it is a different shape. A desktop cover is much wider than it is tall, and the mobile view is nearly square by comparison, so the left and right edges get cut away on a phone.
There is no size that fits both perfectly. The working rule is to upload at 851 by 315 and keep anything that matters, text, a face, a logo, in the middle two thirds. Treat the outer edges as decoration that may not survive.
Link previews and the 1.91:1 shape
When you paste a link, Facebook pulls a preview image from the page rather than from anything you upload. That image needs to be at least 1200 by 630 to get the big preview card. Below about 600 pixels wide, Facebook falls back to a small thumbnail beside the text, which is much easier to scroll past.
If you run the site being shared, that image is set by the og:image tag on the page. Resizing it to 1200 by 630 is the whole fix.
File size and format
Save photos as JPG. Facebook re-compresses everything on upload, and starting from a JPG at the right dimensions gives a better result than handing it a huge PNG.
For flat graphics and anything with text, PNG holds edges better. Facebook is fairly aggressive with compression on text, so if a graphic comes out muddy, try PNG at the exact pixel size rather than a larger JPG.
If you need a smaller file for a slow upload, compress to 200 KB first. At these dimensions that is plenty.
Doing several at once
Preparing a batch of posts or resizing a folder of photos to the same shape? The bulk image resizer applies one preset across every file and returns a ZIP. To reframe before resizing, crop the image first so the preset crops from where you want.

Common questions
Frequently asked questions
- What size is a Facebook post image?
- 1200 by 630 pixels, a 1.91:1 ratio. That is the size Facebook uses for the large link preview card, and it works for a shared photo post too.
- What size is a Facebook cover photo?
- 851 by 315 pixels on desktop. Phones show a narrower, nearly square slice of the same image, so keep anything important in the middle two thirds.
- Why does my Facebook cover look cropped on mobile?
- Because desktop and mobile show different shapes, not different sizes. Desktop is a wide 851 by 315 strip and mobile shows roughly 640 by 360, which cuts the left and right edges away. No single upload fits both, so centre what matters.
- What size is a Facebook profile picture?
- 170 by 170 pixels on desktop, displayed as a circle. Upload it square and keep the subject centred so the corners being cut does not matter.
- What size is a Facebook story?
- 1080 by 1920 pixels, 9:16, the same as an Instagram story. Keep text clear of the top and bottom where the interface sits.
- Why is my link preview showing a small thumbnail?
- The image on the linked page is under about 600 pixels wide, so Facebook falls back to the small layout. Set that page's og:image to at least 1200 by 630 to get the large preview card.
- What size is a Facebook event cover?
- 1200 by 628 pixels, essentially the same 1.91:1 shape as a shared post.
- Should I upload JPG or PNG to Facebook?
- JPG for photos, PNG for flat graphics and anything with text. Facebook re-compresses on upload and is rough on text, so a PNG at the exact pixel size usually beats a bigger JPG for graphics.
