Profile pictures

Square uploads that most platforms then display in a circle.

About these tools

Resizing is the most effective way to reduce a file, because size follows pixel count: halving the width and height removes about three quarters of the data before compression begins. It is also a requirement in its own right whenever a platform, print shop or content system expects specific dimensions.

Alongside the general resizer there is a page for each platform size — profile pictures, banners, thumbnails, story frames. Those pages carry the framing rules that go with the dimensions: which parts of a banner the interface covers, where a circular crop cuts, and how small the image will actually be displayed. The dimensions are the easy half of the problem.

Questions people ask

Will a platform preset crop my photo?

Only if its shape differs from the preset's. The preset pages fill the target size completely: the image is scaled until it covers the frame and the overflow is trimmed equally from both sides, so the centre of the photo is kept. If the subject is off-centre, crop it yourself first with Crop image, then run the preset.

How do I resize without cropping anything?

Use Resize image. It fits the photo inside the width and height you enter and keeps the original proportions, so nothing is cut off — the result may be narrower or shorter than the box in one direction.

Can I make a small image bigger?

Resizing up stretches the existing pixels and looks soft. Image upscaler is built for that job: it enlarges in steps of at most 2× and sharpens afterwards, which holds edges noticeably better than a single jump.
