Why this matters

Facebook automatically crops and re-encodes images that don't match its expected aspect ratios. A timeline post photo at the wrong ratio gets letterboxed or brutally cropped; a cover photo that's a few pixels short looks blurry. Pre-sizing your images takes under a minute and guarantees your photo displays exactly as intended in every placement.

Step by step

  1. 1
    Open the Image Resizer
    Drop in your photo.
  2. 2
    Choose the Facebook placement
    Post (1200×630), Cover photo (820×312), Story (1080×1920), Profile (170×170), Event cover (1920×1005).
  3. 3
    Adjust the crop
    Drag the focus area — especially important for cover photos where mobile and desktop show different crop zones.
  4. 4
    Download
    Save the resized image.
  5. 5
    Upload to Facebook
    Your image displays cleanly with no auto-crop.

Frequently asked questions

What size should a Facebook post image be?

1200×630 pixels is the recommended size for shared link previews and regular photo posts. Square posts (1080×1080) also display well.

What are Facebook cover photo dimensions?

820×312 px on desktop, 640×360 px on mobile. A 820×312 crop covers both adequately; focus your important content in the center 560×312 zone.

What size is a Facebook profile picture?

Displayed at 170×170 px on desktop, 36×36 in the feed. Upload at 360×360 or larger for a crisp circle crop.

Is my image uploaded when resizing for Facebook?

No. All resizing happens in your browser; your photos are never sent to a server.

Does Facebook compress my image after I upload it?

Yes — Facebook re-encodes JPGs. For best quality, upload a JPG at 85%+ quality, 1200 px wide, and let Facebook handle the final encode.

What format works best for Facebook images?

JPG for photos, PNG for graphics with text. PNG files are sometimes recompressed more aggressively by Facebook, so JPG often looks better for photos.
