Choose a shape for your image
Choose a setting here, then check your image in the editor.
| Setting | When to use it |
|---|---|
| A square frame 1080 x 1080 px | Keep equal space across and down. Start here for a centered product or a simple graphic. |
| A portrait frame 1080 x 1350 px | Give a person or tall product more room than a square provides. |
| A tall frame 1080 x 1920 px | Prepare a full-height image. Try Fit when a wide source loses too much in the crop. |
| A wide frame 1200 x 630 px | Keep more of a wide scene or leave space beside your subject for text. |
Canvas size. For an exact size, choose Custom size. Turn off Keep this shape before you enter a new width and height.

A few things to know.
Start with your largest clear copy. Making a small image bigger adds pixels, but cannot bring back lost detail.
Use Fit to keep the full image. Use Fill to cover the whole frame and crop the edges.
Check faces, logos, and text in the preview. A new shape can cut off parts near the edge.
Your questions, answered.
How do I resize an image to a custom size?
Choose an image and select Custom size. Turn off Keep this shape if you want a new shape. Enter the width and height in pixels, pick Fit or Fill, and create your image.
Will resizing make a blurry photo sharp?
No. A larger size cannot restore detail that is missing from the source. Start with a clear photo that is at least as large as your chosen size.
Does resizing always make the file smaller?
No. Pixel size and file size are different. Format, quality, and image detail also affect the number of bytes. Use the image compressor if the file is still too large.
