Questions about this tool

What size does this Facebook Page cover preset create?

It creates an image that is exactly 851 pixels wide and 315 pixels tall. Meta's current fast-loading Page cover canvas, which Facebook can crop, resize, and partly overlap across screens. Platform guidance can change, so recheck it before a high-stakes campaign.

Will the result be exactly 851x315 pixels?

Yes. Every fitting mode creates a 851x315px canvas, and the result card shows the measured dimensions before download.

What is the difference between crop, fit, and stretch?

Crop fills the canvas without distortion and trims the long edges. Fit keeps the full image and adds padding. Stretch fills the canvas but can distort proportions.

Is the image uploaded for resizing?

No. The browser decodes, resizes, previews, and exports the image locally. The source and output images are not sent to Peelaway.

Does this guarantee the same crop on every Facebook screen?

No. Facebook can crop and resize covers for different screens, partly cover a Page banner with the profile picture, and display profile images as circles. Keep important details away from vulnerable edges and preview the result on Facebook.
