How it works

  1. 1

    Upload your image

    Drag your image into the field or pick a file. It stays entirely on your device — nothing is sent to a server.

  2. 2

    Choose a format

    Pick the Facebook format you need. The preview immediately shows how your image will be cropped.

  3. 3

    Download

    One click and you get the image at exactly the pixel dimensions Facebook expects — ready to upload.

Popular use cases

  • Content creators

    No cropping by the app

    Upload images at the right dimensions instead of letting Facebook decide which part of your subject gets cut.

  • Cross-posting

    One shot, every format

    Turn a single photo into square, portrait and landscape versions — no image editor required.

  • E-commerce

    Consistent product shots

    Bring all product photos to the same dimensions so your feed looks tidy and professional.

  • Agencies

    Prepare assets fast

    Adapt client material in seconds without opening Photoshop or taking up a licence seat.

  • Photography

    Keep your resolution

    Export at the full recommended resolution so your images are not displayed unnecessarily soft.

  • Profile optimisation

    Profile pictures without distortion

    Get your profile picture into the right aspect ratio up front instead of wrestling with it on upload.

Facebook post images display in a 1.91:1 ratio (1200 × 630 pixels) — the same format as link previews. The cover photo measures 820 × 312 pixels, stories 1080 × 1920.

The cover photo needs care: it is cropped considerably more on mobile than on desktop. Keep important content centred.

All processing runs in your browser; your image is never uploaded.
