A Facebook image resizer for covers, posts, Stories and ads
Facebook shows the same picture at different shapes depending on where — and on what — it is seen. A Page cover is uploaded at 851 × 315 but displayed at 820 × 312 on a computer and 640 × 360 on a phone, so a banner that looks perfect on a laptop can lose its logo on mobile. This Facebook image resizer prepares covers, feed posts, profile pictures, event and group covers, Stories and ad images at the sizes Facebook recommends as of 2025.
Choose a size and the preview shows the result before you download. For the Page cover, dashed frames mark what desktop and phone visitors actually see, with the phone-only crop shaded. Drag the photo to reposition it, zoom in, or switch to “Fit inside” to keep a whole flyer or screenshot on a background colour. The images are processed in your browser and never uploaded to a server.
How to use the Facebook Image Resizer
- Drop your image (or several) onto the upload area.
- Pick a Facebook size — Page cover, profile picture, feed post, event cover, Story or ad.
- With “Crop to fill”, drag the preview until the important part sits inside the guides. Use Zoom to crop closer. Choose “Fit inside” to avoid cropping at all.
- Check the before-and-after dimensions and file size under the preview.
- Press “Download JPG”, then upload the file on Facebook. For several images, download them together as a ZIP.

Facebook image sizes as of 2025
These are the recommended upload sizes. Facebook resizes and compresses everything you upload, so starting at these dimensions gives it the least to change.
| Image | Upload size (px) | Shape | Notes |
|---|---|---|---|
| Page cover | 851 × 315 | about 2.7:1 | Shown 820 × 312 on desktop, 640 × 360 on phones |
| Personal profile cover | 1200 × 675 | 16:9 | Shown about 820 × 462 on desktop |
| Group cover | 1640 × 856 | 1.91:1 | Phones crop the sides |
| Event cover | 1920 × 1005 | 1.91:1 | Minimum 1200 × 628 |
| Profile picture | 400 × 400 | 1:1 | Displayed as a circle |
| Feed post | 1080 × 1080 or 1080 × 1350 | 1:1 or 4:5 | 4:5 takes more of the feed on phones |
| Link preview | 1200 × 630 | 1.91:1 | Set as og:image; minimum 600 × 315 |
| Story or Reel | 1080 × 1920 | 9:16 | Keep text out of the top and bottom 250 px |
Designing a Page cover for desktop and phones
An 851 × 315 cover is about 2.7 times as wide as it is tall, but phones display covers at 640 × 360 — a 16:9 shape. To fill that shape the phone keeps the full height and cuts the sides, leaving only the central 560 or so pixels of the width. Desktops show nearly the whole width. So the safe area for a logo, a headline or a face is roughly the middle 560 × 315 of your cover.
Turn on the guides to see both views at once: the green frame is what phones show, the blue frame is the desktop view, and anything in the shaded strips is visible on computers only. If your design has text near the edges, choose “Fit inside” and a background colour, or move the text inwards before you export.
Ad images and Stories
- For feed ads, 1:1 (1080 × 1080) works everywhere; 4:5 (1080 × 1350) fills more of a phone screen.
- Stories and Reels are 9:16. Facebook places your name, buttons and the reply bar over roughly the top and bottom 250 px, so keep text and logos between the shaded bands.
- Keep text short. Ads with small amounts of text on the image are easier to read on a phone, and the headline field is a better home for the details.
- Export JPG at about 90% quality. Facebook re-compresses uploads, so a larger file does not stay larger.
Link previews and profile pictures
When someone shares your web page, Facebook builds the preview from the page’s og:image. A 1200 × 630 image keeps the preview sharp on high-resolution screens; create the tags with the Open Graph generator. Profile pictures are cropped to a circle, so the round preview in the corner of this tool shows how yours will look in comments. The social media image sizes cheat sheet covers other networks, and the Instagram image resizer handles cross-posting.
Facebook Image Resizer FAQ
What size is a Facebook cover photo?
Upload a Page cover at 851 × 315 pixels. It displays at 820 × 312 on computers and 640 × 360 on phones, so keep logos and text in the central area. Personal profile covers work well at 1200 × 675.
Why is my Facebook cover cut off on mobile?
Phones show the cover at a 16:9 shape, which is much less wide than 851 × 315, so the left and right edges are hidden. Use the phone guide in this Facebook image resizer to keep important content in the middle.
What is the best size for a Facebook post image?
1080 × 1080 for a square post or 1080 × 1350 for a portrait post. Portrait images take up more space in the mobile feed.
How do I stop Facebook from cropping my profile picture?
Facebook always shows profile pictures as a circle. Resize to 400 × 400 and use the circle guide to keep your face in the centre with some space around it.
Does Facebook reduce image quality?
Facebook compresses every upload. Uploading at the recommended pixel size avoids an extra resize step, which is the main cause of soft or blocky images.
Are my images uploaded to your server?
No. The resizing runs in your browser on your own device, and your images are never sent anywhere.
