Resize Image for Facebook Cover Photo Online Free
Lock exports to 820×312 pixels— the common desktop cover canvas designers use to keep logos inside Meta's safe zone. Distinct from generic resize or Instagram presets so you never mix up aspect ratios between platforms.

What problem this tool solves
Page admins download random large photos and watch Facebook auto-crop heads and taglines. Exporting to an exact 820×312 frame first lets you control composition before Meta applies its own responsive masks. This URL targets only Facebook cover intent — not Facebook feed squares (Facebook post tool) and not Instagram (Instagram hub).
Recommended output specification
| Property | Value |
|---|---|
| Locked dimensions | 820 × 312 px |
| Aspect ratio | ≈ 2.63∶1 — ultra-wide banner |
| Typical download | JPEG from this tool |
| Mobile caveat | Phones crop tighter — keep copy centred |
How to use
- Upload a high-resolution master — wider than 820 px if possible.
- Pick Contain vs Cover depending on whether cropping is acceptable.
- Resize, download, then upload to your Page. Optional: Compress JPG if Meta warns about slow uploads.
Best practices
- Keep faces and logos inside the centre 60% — mobile crops aggressively.
- Avoid tiny text along top/bottom edges — those zones disappear first on phones.
- Use PNG sources for logos, then export JPG here for smaller upload weight.
Common mistakes
- Using a square Instagram asset directly — wrong aspect, awkward letterboxing after Facebook crops.
- Stretching logos to fill width — use vector originals where possible.
Privacy and quality
Local resizing keeps unreleased campaign artwork private until you publish on Meta. Quality depends on your source; wide masters downscale cleanly — tiny sources upscale poorly.
Frequently Asked Questions
Is 820×312 still correct for Facebook covers in 2026?
Meta periodically tweaks how covers crop on mobile vs desktop. 820×312 px remains a widely used planning canvas for the desktop cover area; always preview on a real Page after upload because phone viewers see a tighter vertical crop.
Does Facebook upload my image to ImageTool?
No. ImageTool processes locally in your browser. Facebook is unrelated until you upload there yourself.
Should I use Cover or Contain when resizing?
Use Contain if logos or faces must not be cropped. Use Cover if you need the banner to feel full-bleed and can afford slight edge loss.
What file type should I upload to Facebook after downloading?
JPEG at high quality is typical for photographic banners. This tool exports JPG.
Where should I place headlines so mobile doesn’t chop them?
Keep mission-critical words inside the horizontal middle band — phones aggressively crop top/bottom strips compared with desktop previews.
Night scenes / noisy JPEG — any tips?
Heavy noise enlarges bytes — lightly denoise before export if Meta complains during upload or if previews look gritty after recompression.
