Facebook cover photos have different display dimensions depending on the device, and this is one of the most confusing parts of preparing graphics for the platform. On desktop, the cover displays at 820 by 312 pixels. On mobile, it displays at 640 by 360 pixels, which is a narrower and slightly taller aspect ratio. Facebook officially recommends uploading at 851 by 315 pixels to split the difference, but for the best quality across all devices you can upload at 1920 by 1080 pixels and let Facebook scale down cleanly. The key insight to internalise is that mobile crops the top and bottom of a cover photo more aggressively than desktop does. The safe zone for important content such as text, logos, and faces is the central 820 by 180 pixel band, roughly centred vertically within the cover canvas you upload.
Profile pictures on Facebook are stored at 360 by 360 pixels even though they display at 170 by 170 pixels on desktop and 128 by 128 pixels on mobile. Facebook recommends uploading at 360 by 360 pixels minimum but supports up to 2048 by 2048 pixels for the source file. Uploading larger gives Facebook a higher resolution master to draw from when it needs to display your photo in various contexts, which include 32 by 32 pixels in comment threads, 50 by 50 pixels in notifications, 128 by 128 pixels on the mobile profile, and varying sizes inside chat and reaction overlays. Profile pictures are cropped to a circle in most feed contexts but still displayed as squares in some older list views and ad placements, so keep important content inside both the square and the inscribed circle.
For post images, 1200 by 630 pixels with a 1.91 to 1 aspect ratio is the standard recommendation that displays cleanly across the news feed, on Marketplace previews, and when external links pointing to your post are shared. For event cover photos, 1920 by 1005 pixels provides the highest quality and gives Facebook enough resolution to display sharply on every device including 4K tablets and high-DPI laptops. Facebook scales the event cover down to fit smaller containers, so a high-resolution source ensures it always looks crisp without obvious upscaling softness. Group cover photos use 1640 by 856 pixels with a 16 by 8.4 ratio that Facebook chose to balance desktop and mobile display, and importantly the group name and other UI elements overlay the bottom portion of the cover image in most contexts.
Keep text and key visuals within the central 70 percent of any Facebook cover image to account for edge cropping on smaller screens. The mobile crop alone can take 56 pixels off the top and bottom of a desktop cover, and notch-equipped phones can push that further. For shared link previews, the og:image meta tag on your website should point to a 1200 by 628 pixel image to fill the preview card on every device. Images smaller than 600 by 315 pixels for an og:image will display as a small thumbnail in the news feed instead of a full-width link card, which dramatically reduces the visual presence of your shared link and almost always lowers click-through rate compared to a properly sized preview image.
Upload your image and resize to your needed Facebook dimension: 851×315px for a cover photo, 1200×630px for a post image, or 360×360px for your profile picture.
Step-by-step guide to resize image for facebook:
Choose the Facebook image type
Decide which Facebook placement you are preparing for. Cover photo displays at 820 by 312 pixels desktop and 640 by 360 pixels mobile, with 851 by 315 commonly used as a single safe upload. Profile picture uploads at 360 by 360 and displays at 170 by 170 desktop. Post image is 1200 by 630. Shared link image is 1200 by 628. Event cover is 1920 by 1005. Group cover is 1640 by 856.
Upload your image to FixTools
Open the Image Resizer on this page and either drag the file into the upload zone or tap to select from your computer or phone. The tool accepts JPG, PNG, WebP, and most common camera formats. Higher resolution sources give you more flexibility because resizing down is much cleaner than resizing up later when you discover a placement needed something larger.
Enter the Facebook dimensions
Type the width and height for your chosen Facebook image type. For a cover photo upload, enter 851 in the width and 315 in the height, or use 1920 by 1080 if you want extra resolution for retina display. For a post image, enter 1200 by 630. Lock Aspect Ratio off when matching Facebook targets exactly, since Facebook expects the precise dimensions.
Resize and download
Click Resize and wait for the preview to refresh. Verify the output looks correct, particularly that no important content sits in a corner that will be cropped on mobile. Then click Download to save the file. Save as JPG at 90 percent quality for photos, or PNG for logos and graphics with text or sharp edges where JPG artefacts would be visible.
Upload to Facebook
Upload the resized image to Facebook through the relevant page, profile, event, or group settings. The image arrives at native dimensions, which means Facebook's on-upload processing has less to do and the final displayed version retains more sharpness, especially on Retina laptops and high-pixel-density phones where Facebook's aggressive compression of larger source files becomes visible.
Common situations where this approach makes a real difference:
A local business owner resizes their storefront photo to 851 by 315 pixels for their Facebook cover photo.
The owner runs a neighbourhood coffee shop and wants the Facebook page to feel inviting and current. By resizing a fresh photo of the storefront to the standard cover dimensions and placing the cafe name within the central safe zone, the cover reads cleanly on both desktop and the mobile app. New visitors who land on the page get an immediate sense of the place rather than a stretched, cropped, or pixelated photo that the previous owner had uploaded straight from a phone without resizing first.
A nonprofit coordinator resizes a fundraising event photo to 1200 by 630 pixels for a Facebook post.
The coordinator is running a year-end giving campaign and wants the announcement post to occupy the full news feed card rather than appearing as a small thumbnail. By resizing the event photo to exactly 1200 by 630 pixels before scheduling the post through Meta Business Suite, the announcement displays as a feed-stopping full-width visual, which drives notably higher engagement and link clicks to the donation page compared to the previous campaign that used an unresized phone photo and rendered as a thumbnail.
A graphic designer resizes a company logo to 360 by 360 pixels for use as a Facebook profile picture.
The designer is rebranding a client and needs to deliver a clean profile picture asset that will look sharp at every size Facebook uses, from the 360 master down to the 32 by 32 comment thumbnail. By exporting the logo as a 360 by 360 pixel PNG with the brandmark centred inside the inscribed circle of the square canvas, the profile picture survives the Facebook circular crop on the feed while still working in the square contexts that some legacy placements still use, giving the client one asset that works everywhere.
A wedding photographer resizes a portfolio photo to 1920 by 1005 pixels for a Facebook event cover.
The photographer is hosting a free portfolio review event and wants the Facebook event page to look professional from the first impression. By resizing a hero portfolio photo to the recommended event cover dimensions and placing the event title and date in the central safe zone, the cover looks sharp on every device that potential attendees use to view the invite, which lifts the RSVP rate compared to the previous event where the cover photo had been uploaded at the wrong dimensions and ended up cropped and soft.
Get better results with these expert suggestions:
Upload cover photos at 1920x1080px for best quality
Although Facebook officially recommends 820 by 312 pixels for covers, uploading at 1920 by 1080 pixels gives Facebook a much higher resolution source to scale from. Facebook downsamples this for display, and the result is noticeably sharper than uploading at the minimum recommended size, especially on Retina screens, 4K monitors, and high-DPI mobile devices where the difference between native and upscaled cover photos is immediately obvious to a critical eye.
Design for the mobile crop zone on cover photos
Mobile devices crop approximately the top 56 pixels and bottom 56 pixels of a Facebook cover photo compared to the desktop display. On an 820 by 312 pixel canvas the safe zone for critical content sits between y equals 56 pixels and y equals 256 pixels. On a 1920 by 1080 pixel canvas keep your important content between roughly y equals 130 pixels and y equals 590 pixels. Anything outside this central band may be partially or fully cut on mobile.
Use PNG for profile pictures with logos or text
Facebook re-compresses every JPG upload and can introduce visible artefacts on logos and text, particularly around the hard edges of vector-like content where the JPG discrete cosine transform produces visible halos. For profile pictures containing sharp lines, brand text, or vector logos, upload as PNG. Facebook still compresses PNGs internally, but the artefacts are typically less visible than the equivalent JPG compression on high-contrast graphics.
Post images at 1200x630px to fill the full news feed width
Images smaller than roughly 476 pixels wide display as a small thumbnail in the news feed rather than spanning the full post card width. Images at exactly 1200 by 630 pixels fill the entire card and present as a large feed-stopping visual. The difference in scroll-stopping power between a thumbnail and a full card is significant, and it shows up clearly in both organic engagement and paid ad performance metrics across A/B tests.
