    How to resize an image for Facebook Cover

    Crop one image to the exact Facebook Cover frame: 851x315 pixels. The crop ratio is locked, export is JPG, and processing stays in your browser.

    Facebook Cover size notes

    Crop to the wide Facebook cover frame so the header area is ready before upload.

    1. Upload a JPG, PNG, or WebP image.
    2. Move or zoom the locked crop box to keep the important subject inside the frame.
    3. Click Export JPG to create an exact 851x315 image.
    4. Download the JPG and upload it to Facebook Cover.

    Why use this Facebook Cover resizer?

    Platform pages save time because the canvas dimensions and aspect ratio are already locked. You can focus on framing instead of looking up pixel sizes or stretching the image.

    Facebook Cover size: 851 × 315 pixels

    This tool creates a wide cover-image crop at 851 × 315 pixels with a 851:315 aspect ratio. Pixel dimensions describe the exported canvas; the ratio describes its shape. Both matter because uploading a file with a different shape can lead the platform to crop, pad or reposition it.

    The preset is a preparation shortcut, not a guarantee of identical display in every app view. Social interfaces can show the same image at different sizes, add controls over it or crop previews according to the device and placement.

    Crop to the frame without stretching

    The editor uses crop-to-fill. It scales the photograph proportionally until the target frame is covered, then removes the portions outside that frame. Faces and circles stay correctly proportioned; unlike forcing separate width and height values, the process does not stretch the source.

    Move the crop so the important subject remains visible. A wide source fitted into a tall frame loses material from the sides, while a tall source fitted into a wide frame loses material from the top and bottom. If nothing can be removed, use the general resizer and accept padding rather than a full-bleed crop.

    Keep important content inside a safe composition

    Place faces, logos and essential words away from the outer edges. Design text at a size that remains readable on a phone, simplify busy backgrounds and avoid putting critical information where interface buttons or profile elements may overlap it. Review the upload preview before publishing.

    For a series of related posts, use a consistent crop and visual hierarchy. The exact canvas is only one part of a successful image: clear contrast, a recognisable subject and honest content matter more than filling every pixel with detail.

    Source quality, JPG export and compression

    Start with an image at least as large as the target when possible. Enlarging a small source can make blur and JPEG artefacts more visible. The page exports JPG, which is suitable for photographs but cannot preserve PNG transparency. Transparent areas are flattened during export.

    The destination may compress the upload again. Keep an original project file, inspect the downloaded JPG before upload and then inspect the platform preview. If a separate file-weight limit applies, use the compression tool after cropping to final dimensions.

    Current guidance and changing platform layouts

    Platform documentation and interfaces can change without this page changing automatically. The preset describes exactly what this tool exports. When a campaign or account depends on a specific placement, compare the current official help page and test the image in that placement before scheduling or publishing it.

    Using the Facebook cover canvas safely

    The 851 × 315 preset is a practical legacy cover canvas for people who need that exact export. Facebook can present Page covers in changing, wider layouts and may crop them differently across devices. Keep essential words, faces and logos near the centre and let the edges contain expendable background.

    Do not assume the exported dimensions guarantee an identical Page display. Check Meta's current guidance for the destination you manage, upload the image and inspect both desktop and mobile previews. The tool changes framing and pixels; it does not validate branding, copyright or Page policy.

    Private processing in your browser

    The selected image is cropped and exported locally in your browser. It is not uploaded to Image Online Free for processing. You remain responsible for the rights to the source image, the content you publish and storage of the downloaded copy.

    FAQ

    What size does this page export?

    Will the image be stretched?

    No. The crop-to-fill workflow preserves proportions and trims only the parts outside the locked frame.

    Can I reposition the crop?

    Yes. Drag the image and adjust the crop area before exporting.

    Is PNG transparency kept?

    No. Output is JPG, so transparent areas are flattened by the browser export.

    No. Cropping and export happen locally in your browser.

    Can I use another platform size?
