Your image is smaller than the target, so the result will be upscaled and soft. Use a higher resolution photo for a sharp output.
This page outputs exactly the target size. If your image is smaller, the file is enlarged to reach it and looks softer. Enlarging cannot recover detail that was never captured.

Your images never leave your browser
All processing happens locally on your device. Nothing is uploaded to a server, stored, or tracked.
A Facebook cover is one file that Facebook crops two different ways, and nobody uploads two. Desktop shows a wide band, mobile shows a narrower and taller slice of the same image, and your profile picture covers the bottom left on one of them. This page sets the upload size and maps all three hazards so the important part survives every layout.
How it works
One upload, two different crops
Facebook does not let you supply a separate image for desktop and mobile. It takes one file and shows a wide band on desktop and a narrower, taller slice of that same file on a phone. That is why a cover can look correctly composed on a computer and badly cropped on a phone, and it is a composition problem rather than a sizing problem. Choosing the right upload size makes it sharp; choosing the right safe zone makes it readable on both.
| Measure | Value | What it means |
|---|---|---|
| Desktop display | About 820 × 312 px | What a desktop browser shows |
| Mobile display | About 640 × 360 px | A narrower, taller crop of the same file |
| Recommended upload | 1,640 × 624 px | Twice the desktop size, for high-DPI sharpness |
| Approximate ratio | 2.63:1 | A wide, short frame |
| Profile photo overlap | About left 170 px, bottom 75 px | Covered on desktop by your profile picture |
| Practical file size | Under about 100 KB | Facebook compresses larger files harder |

The safe zone is the part nobody shows you
Two things cover your content and both are invisible in the editor you designed it in. On desktop, your profile picture sits over the bottom left of the cover, hiding roughly the leftmost 170 pixels and the bottom 75 pixels. On mobile, only the central 640 pixels of width survive at all. Those two constraints overlap, and the area they leave is the centre and centre-right of the image. That is where text, a logo, and a call to action belong.
- Desktop: your profile picture covers the bottom left. Keep content out of it.
- Mobile: only the central 640 pixels of width remain visible.
- Place text and logos in the centre and centre-right.
- Never put critical content within roughly 100 pixels of any edge.
- Check the result on a phone, not only on a desktop where it looks fine.
NoteThe area left by both crops is the centre and centre-right. That is the whole safe zone.
Designing a cover that survives the crop
Keep the text short. A cover is not a poster, and a headline that reads on a large monitor becomes unreadable when a phone shows a 640 pixel wide slice of it. A single short line centred in the safe zone works; a paragraph does not. Leave the edges visually quiet, because the crop will land there and a busy edge looks like a mistake. Match the colours to the page so the cover reads as part of the profile rather than a banner sitting on top of it.
- One short headline. A paragraph will not survive the mobile crop.
- Keep the text well inside the centre so the desktop crop cannot reach it.
- Leave the outer areas quiet, since that is where the crop lands.
- Use PNG for text and logos. JPG softens hard edges.
- Match the page colours so the cover looks integrated.
Why the file size target is small
The cover sits at the top of every visit to the page, so a heavy file slows the most visited screen on the profile. Facebook also compresses larger uploads more aggressively than smaller ones, which means an oversized cover is degraded in transit and arrives softer than the file you uploaded. A modest target of about 100 KB keeps the file light and avoids that double compression. At 1,640 by 624, a balanced quality JPG reaches that comfortably, and the image is small enough on screen that the difference is not visible.
- The cover is the first thing on every profile visit, so weight matters.
- Facebook compresses larger uploads more aggressively.
- About 100 KB is the commonly recommended target.
- At 1,640 by 624 a balanced JPG reaches that with no visible loss.
- Use the 100KB compressor if the file is larger.
NoteA heavy cover is slowed and then compressed harder in transit. Both are avoidable.

Frequently asked questions
What size should I upload for a Facebook cover photo?
Upload at 1,640 by 624 pixels. Facebook displays it at roughly 820 by 312 on desktop and 640 by 360 on mobile, so uploading at twice the desktop size keeps it sharp on high-DPI screens where an 820 pixel upload looks soft.
Is 820 by 312 the right upload size?
No, that is the display size, not the upload size. Uploading at 820 by 312 gives a soft result on a high-DPI screen because the image is being enlarged to display. Upload at 1,640 by 624 instead.
Why does my Facebook cover look different on mobile?
Facebook crops the same file differently on each device. Desktop shows about 820 by 312 and mobile about 640 by 360, so the mobile view cuts the sides and shows more of the top and bottom. You cannot upload a separate image for each.
What is the Facebook cover safe zone?
The centre and centre-right of the image. On desktop your profile picture overlaps roughly the left 170 pixels and the bottom 75 pixels, and on mobile only the central 640 pixels of width remain visible. Keep text and logos out of both areas.
Should the cover be JPG or PNG?
Use JPG for a photographic cover, because the file stays small. Use PNG when the cover contains text, a logo, or hard edges, since JPG compression softens them. Facebook compresses larger files harder, so keeping the file small matters either way.
How small should the cover file be?
Under about 100 KB is the commonly recommended target, because Facebook compresses larger files more aggressively and a heavy cover slows the top of every page. You can compress it to 100KB with little visible change at this size.
Can I batch resize Facebook cover images?
Yes. Add a folder of banners, resize each to 1,640 by 624, and download a ZIP. Everything is processed on your device.
