Scaling down is lossless in perceived quality; scaling above the original size always softens the image because the extra pixels are invented.

Resize an image to 1920x1080, 1080x1080 or 1200x630

The presets fill in the common sizes with one click: 1920×1080 for a full-HD screen or video thumbnail, 1080×1080 for a square social post, 1200×630 for the link-preview image social platforms show when a page is shared, 800×450 for an image in the body of a blog post, and 400×400 for a profile picture.

With keep aspect ratio switched on, the resizer protects the shape of your picture, so a photo that is not already 16:9 will not come out at exactly 1920×1080 — one side will be smaller. Switch it off to force the exact size, and the picture will be stretched or squashed to fit. For a clean exact size from a photo of a different shape, crop it to the right proportions first, then resize.

Everything happens in your browser, so the image is never uploaded.

Resize an image to 500x500 or any exact size

Any size the presets do not cover can be typed in directly: enter the width and the height in pixels and download. Common ones people need: 500×500, 600×600 and 1000×1000 for square product photos and profile images, 1280×720 for HD video thumbnails, 1080×1920 for vertical stories and phone wallpapers, and 2560×1440 for a high-resolution desktop background.

Square sizes need one extra decision. A typical camera photo is not square, so with keep aspect ratio on, 500×500 will come out as 500 pixels on its longer side and less on the other. If the result must be exactly square, crop the photo to a square first and then resize, rather than switching aspect ratio off — that would squash the picture instead of trimming it.

Making an image larger than the original does not add detail. Resizing a 300-pixel photo up to 1000×1000 gives a bigger, softer picture, not a sharper one, so start from the largest original you have.

Frequently asked questions

Type 500 into both width and height and download. If the photo is not already square, crop it to a square first; otherwise keep aspect ratio will make one side smaller than 500, and switching it off will squash the picture.

Keep aspect ratio protects the shape of the picture, so a photo that is not already 16:9 comes out with one side smaller. Switch it off to force the exact size, which stretches the image, or crop to 16:9 first for a clean result.

Making an image smaller is safe. Enlarging beyond the original dimensions interpolates pixels that were never captured, so it always looks softer.

Match the maximum width the image is displayed at. For a typical blog body that is 800 to 1200 pixels; full-width heroes need 1600 to 1920.
