What stretching for Facebook Cover solves

Need to stretch an image for Facebook Cover when the source aspect does not match 820 × 360? Uniform resize keeps proportions — fine for thumbnails, wrong when that slot expects a fixed fill. A dedicated stretcher lets you set width and height independently so the bitmap fills the frame.

ImageStretcher is built for quick local Facebook Cover edits: open a file, confirm 820 × 360, preview on canvas, and download. Ideal when you want a controlled stretch on purpose — without cropping the subject away from the Cover box.

Design tools excel at layouts. When you already have a finished bitmap and only need non-uniform stretch for Facebook Cover at 820 × 360 — no brand kit, no account, no cloud upload — this page is the shorter path.

How to stretch an image for Facebook Cover

Four steps from file to a Facebook Cover download at 820 × 360. The whole flow runs in the browser — use the tool above, stretch, and save without creating an account.

  1. Step 1

    Open an image

    Drop a common image — PNG, JPEG, WebP, GIF, and more — into the upload area, or pick a file from your device. Nothing is sent to a server while you prepare a stretch for Facebook Cover.

  2. Step 2

    Confirm 820 × 360

    Width and height are prefilled to the Facebook Cover size (820 × 360 px). Unlock aspect ratio when you need independent axes; lock it for proportional resize toward this frame.

  3. Step 3

    Preview the stretch

    The canvas updates as you adjust controls so you can judge how each axis warps the subject before you commit. If framing is wrong, crop first, then stretch to 820 × 360.

  4. Step 4

    Download

    Export as PNG for crisp edges, or JPEG or WebP when you need a smaller file. Your original stays on disk; only the new Facebook Cover file is written when you save.

When to stretch images for Facebook Cover

Jobs where the Facebook Cover frame at 820 × 360 beats a generic resize.

  • Exact Cover frames

    Facebook expects a 820 × 360 Cover box. Unlock the lock, confirm width and height, and let the stretcher remap pixels to that box.

  • Fill the Cover box

    When cropping would cut a face, a logo, or an edge off the Cover frame, independent axes to 820 × 360 let the subject fill Facebook without discarding the rest of the bitmap.

  • Matching a template

    This page is prefilled to the Facebook Cover template. Change the size only if you know the platform changed this frame.

  • Private local edits

    Work to 820 × 360 without a cloud uploader. Drafts stay on your device from open through download.
