Resize Image for Facebook Online — Free
Runs 100% in your browser — your files never leave your device.
Facebook compresses and crops images that miss its expected ratios, and blurry feed posts cost attention. Choose the placement (1.91:1 feed post, 1:1 square, 9:16 story) and your image is center-cropped to the shape, then scaled to Facebook's recommended pixels. Everything runs locally in your browser.

About this tool
Facebook's key image dimensions
Feed images display at up to 1200 pixels wide (square 1200×1200 renders best), link preview images at 1200×630, and cover photos at 820×312 on desktop. Uploading at or above these sizes lets Facebook's rendering work without destructive downscaling.
The link-preview size is the one people miss
When your page is shared, Facebook pulls the og:image at its own preferred dimensions — 1200×630 with safe margins. Design link images to that shape from the start, and preview with a sharing debugger before relying on it.
Facebook recompresses everything
The platform applies its own compression, which punishes low-quality sources. Upload PNG for graphics with text (compression artifacts around edges are the giveaway) and high-quality JPG for photos.
Frequently asked questions
What size should a Facebook post image be?
1200 pixels wide minimum — 1200×1200 for square, 1200×630 for link previews. Larger is fine; smaller gets upscaled and softened.
Why is my shared link preview cropped?
The og:image ratio does not match Facebook's 1.91:1 preference. Resize the image to 1200×630 here and update the meta tags.
Does the cover photo size differ on mobile?
Yes — mobile crops the sides of the 820×312 desktop cover. Keep key content centered in the middle band.
