About this tool
400 x 400 pixels is what LinkedIn Profile Picture needs: square, 1:1, 0.2 megapixels. Upload anything and it comes back cropped to fit. Shown as a circle. A head-and-shoulders crop reads much better here than a full-body photo. LinkedIn shows this beside every comment you make, at a size where only a head-and-shoulders crop reads clearly. No upload and no account. Your browser does the work, so a large batch is as fast as your machine rather than as fast as a server. Feeding in a different aspect ratio means something gets cut. The preview shows exactly what, so you can reposition instead of discovering it after posting.
How to use this tool

- Check the preview and downloadThe preview shows the exact crop. Reposition if you need to, then save as JPG, PNG or WebP.

Common uses
- Fixing an image a platform rejected for being the wrong dimensions.
- Preparing a batch at 400 x 400 pixels before a scheduled post.
- Resizing on a phone without installing an editing app.
- Updating a LinkedIn headshot.
- Getting a correctly sized image without opening a full editor for a 30-second job.
Tips for better results
- Crop to 1:1 before resizing when the subject matters - then you choose what is lost rather than the tool.
- LinkedIn shows this beside every comment you make, at a size where only a head-and-shoulders crop reads clearly.
- Check the result on the platform itself - feed thumbnails are often cropped again from the size you upload.
- PNG keeps text and sharp edges crisp at this size; JPG is smaller for photographs.
Mistakes to avoid
- Putting important detail near the edges of a 1:1 frame. Platforms crop again for thumbnails and previews.
- Scaling a small image up to hit the pixel count. The file gets bigger; the detail does not come back.
- Letting the image stretch instead of keeping the ratio. A squashed face is more obvious than a tight crop.
- Assuming another platform at the same pixel size behaves identically. LinkedIn shows this beside every comment you make, at a size where only a head-and-shoulders crop reads clearly.
