Image Canvas Padder — the exact size, with no stretching

Drop in any photo and export it at exactly the pixel size a marketplace asks for. If the source is too small or the wrong shape, the tool centres it at its real size and fills the empty canvas around it with a colour or your own backdrop. Nothing is stretched and nothing is cropped by guesswork. A 920 x 1280 phone photo exported as a Pinterest pin comes out as a true 1000 x 1500, with the backdrop colour filling the top and bottom.

  1. Choose the image — press CHOOSE IMAGE(S), or drop files straight onto the canvas. The files are read on your device, they are never uploaded.
  2. Pick a canvas — Pinterest 4:5 (1000 x 1500), Etsy listing (1080 x 1080), Etsy shop banner (1200 x 300) and several more are built in. Press ADD SIZE to add your own; it is remembered on this device.
  3. Place it — ZOOM scales both sides, WIDTH and HEIGHT size one side each, and Lock shape keeps the proportions so the picture cannot distort. UPLOAD BACKDROP puts your own texture behind it.
  4. Export — DOWNLOAD SINGLE for one JPG or PNG, BATCH DOWNLOAD ZIP for a whole listing set at once.

Use it when a marketplace rejects a photo for the wrong dimensions, when your product shots come off a phone and are not 4:5, or when you want one backdrop colour across an entire set of listings. Everything runs inside this tab: no account, no upload, no server. Refreshing clears the canvas, so export before you close the page. Details on data and advertising are in the Privacy Policy.

Drag on the canvas to reposition. Mouse wheel or ZOOM scales both sides; WIDTH and HEIGHT size each side on its own, and the lock stops the picture from stretching. FIT W FIT H FILL FIT 100% place it for you. The canvas is the final export, anything outside it is cropped away.

Pick a ratio and the height follows the width, or the width follows the height. Leave it on CUSTOM to type any size. The x on a row removes that size, and the list is remembered in this browser. Whatever you pick, the export canvas is exactly that size.
