Resize images for every social platform
Each social network crops or rejects images that don’t match its expected dimensions — an Instagram post is a 1:1 square, a YouTube thumbnail is 16:9, and a LinkedIn banner is a wide 4:1 strip. This tool locks the crop box to the exact aspect ratio and pixel size the selected platform expects, so you can drag to frame the shot and export a PNG sized precisely right, without guesswork. Use the zoom slider to crop in tighter, or drag the crop box to reposition it over the part of the image you want to keep. Nothing is uploaded — the crop and resize happen locally on the Canvas API. For a general-purpose crop with custom aspect ratios, try the Image Cropper, or the Image Resizer for resizing without cropping.

What this tool is used for
- Producing a correctly sized image for a specific platform placement.
- Repositioning the subject so it survives a platform's aggressive crop.
- Making one photo work across several platforms with different aspect ratios.
- Checking how much of an image a square crop will discard before committing.
- Preparing a header or a thumbnail at exact required dimensions.
Frequently Asked Questions
- Why does every platform want a different size?
- Because each designs its feed around a different aspect ratio and column width. There is no shared standard, and the numbers change — which is why a graphic that looked right last year can be cropped this year without anything on your side changing.
- What is the safe zone?
- The area guaranteed to be visible after cropping. A platform showing a 16:9 preview of a 1:1 image cuts the top and bottom, so anything critical — a logo, a headline — belongs in the centre. Designing to the crop rather than the canvas is the whole discipline.
- Should I crop or letterbox?
- Crop when the subject is central and the edges are background; letterbox when the whole frame matters, accepting the bars. Stretching is never the answer — a distorted face or logo reads as an error in a way that a crop or a bar does not.
- Does resizing lose quality?
- Downscaling is nearly lossless visually and reduces file size; upscaling invents nothing and only softens. Export at the largest size you need and scale down for the rest — going the other way is what makes a profile picture look blurry next to everyone else's.
- What file size do platforms accept?
- Most cap uploads in the low megabytes and re-encode everything anyway, usually to JPEG or WebP at their own quality setting. That re-encode is why a carefully optimised PNG arrives looking softer — you are compressing something that will be compressed again.
Common errors and gotchas
- Putting the subject near an edge that a platform's own crop will remove.
- Placing text near the boundary, where a UI overlay or a rounded corner covers it.
- Exporting below a platform's minimum dimensions, which then upscales and softens it.
- Assuming the dimensions are stable, since platforms change them without notice.
- Ignoring safe areas for profile pictures, which are usually displayed as circles.
