Resize a Photo to 600 × 600 Pixels

The table shows how rare an exact 600 × 600 pixel rule is. Among the official digital photo specs we have checked, only the Diversity Visa entry asks for precisely this square. The UK sets a minimum of 600 by 750 pixels, a portrait shape, so a 600 × 600 square would be too short for it. India and Singapore name exact sizes that are portrait as well. If your form is one of those, type its numbers into the width and height boxes rather than using 600 × 600.

For the Diversity Visa itself, pixel size is only one of several rules, alongside the head position, background and how recent the photo is. Read the instructions in full before you submit. This page handles the pixel and file-size part; for a full passport or visa photo with the right head size and background, use the Passport Photo Maker.

Other sites that mention a 600 px square, such as online shops, forums or school portals, usually treat it as a recommended display size. In those cases a slightly larger square works too, but 600 × 600 is a reliable middle ground that looks sharp and keeps files small.

Almost every camera photo is a rectangle, usually 4:3 or 3:2, and a 600 × 600 frame is 1:1. Something has to give, and the drawing below shows the three ways it can. This page uses Crop to fill: the photo is scaled until it covers the whole square and the parts that stick out are trimmed. Nothing is distorted, and the result is a full square with no bars.

Crop to fill keeps the center by default, which suits portraits taken straight on. If the face sits higher in the frame, set Crop position to Top, or choose Smart (subject) to let the tool find the main subject. For photos where nothing may be cut, Fit inside keeps the whole image and Pad with color fills the gaps with white. To choose the square by hand instead, draw it with Crop Image and then resize the result here.

A 600 × 600 image has 360,000 pixels, a small fraction of a modern phone photo, so the resized file is light. Saved as JPEG at the default quality of 85, it typically lands far under limits like 240 KB. If a form names a maximum, tick Limit file size and type the number; quality is lowered only if the file would otherwise be too large.

The output keeps the input format unless you choose another under Output format. JPG is the safe choice for photos and forms, PNG keeps hard edges for logos and screenshots, and WebP gives smaller files for websites. Location and camera details are removed by default, which is usually what you want for a photo you upload to an official form or a public profile.

Scaling a large photo down to 600 pixels is the easy direction. Each output pixel is calculated from many input pixels, so edges stay clean and noise from the camera sensor is averaged away. The result usually looks crisper than the original does at the same size on screen.

Scaling up is the hard direction. A crop from a group photo or an old picture saved from a chat app may have only 300 or 400 pixels across the face, and stretching that to 600 adds pixels the camera never recorded. The square will have the right numbers but look soft. If you can, go back to the original file from the camera or phone gallery rather than a copy that was already made smaller by a messaging app.

Auto orient is on by default, so photos taken with the phone held sideways come out the right way up. Without it, some images would be cropped as if they were lying on their side.
