Small Squares at 600x600

600 x 600 pixels is a small 1:1 square, the kind of picture that shows up many times on one page: thumbnails in a gallery or blog archive, product tiles in a catalogue or category grid, avatars beside comments, team photos on an about page, cover images in an email newsletter. It is sharp enough to look clean on a phone screen, and small enough that a page with dozens of them still opens quickly. Some forms and site builders ask for exactly this size, and a picture that is any other shape gets cropped or squashed by the site in ways you cannot control.

Open one picture or a pile of them. The size boxes already read 600 x 600 and the preview shows the square you will get. Download saves a file exactly 600 pixels on each side, named after the original with -600x600 added: team-anna.jpg becomes team-anna-600x600.jpg.

Crop, Fit or Stretch Into a Small Square

At thumbnail size the subject has to fill the frame to be recognisable, and that shapes which mode works best.

Crop to fill, the default, suits most thumbnails and avatars. The picture is scaled until it covers the square and the extra width or height is trimmed. The preview shows the whole photo with the kept square lit and the rest dimmed. Drag the lit square, or tap where it should go, so a face or the main object sits where you want it; a small square has no room for empty sky. When you prepare a batch, every picture keeps its own crop, so pick its thumbnail and place each one.

Fit inside keeps the whole picture, which is what catalogue images of products, logos and book covers usually need. The empty bands are filled with white, black, any colour from the picker, or transparent. A JPG given a transparent background is saved as a PNG, because JPG cannot store transparency. A matching background on every tile makes a grid look consistent even when the originals are all different shapes.

Stretch forces the picture to 600 x 600 without cutting anything. Shapes and faces distort, so it is only for pictures that are nearly square already.

Batches, Formats and Names

Add more pictures with the + tile after the thumbnails; each gets the same size and mode. With two or more, Download as offers one ZIP, separate images (the share sheet on a phone) or, in Chrome and Edge on a computer, a folder you choose where every file is written directly.

Formats are kept by default: JPG stays JPG, PNG stays PNG, WebP stays WebP. The menu beside Download converts them to JPG, PNG or WebP, and the Quality slider sets JPG and WebP quality. Going from a big camera photo down to 600 pixels throws away most of its pixels, so the resizing uses a Lanczos filter, which keeps small details and text readable instead of letting them blur or shimmer. Phone photos are turned the right way up from their EXIF orientation first. A file that is already 600 x 600 in the chosen format comes back untouched.

Need another square? Type a size into the boxes or open a page made for it: 400x400 for profile pictures, 512x512 for icons and stickers, 1000x1000 or 1200x1200 for larger product images. To shrink by percentage or keep each photo's own shape, use Batch Resize.

Frequently Asked Questions

How do I make square thumbnails from photos of different shapes?

Add them all, keep Crop to fill, and pick each thumbnail to drag its crop onto the subject. Every picture comes out 600 x 600, so the whole set lines up in a grid.

Should thumbnails be cropped or fitted?

Crop people, places and scenes, where filling the tile matters. Fit products, logos and covers, where cutting an edge would hide something; give them a background that matches your page.

Can I make 600x600 thumbnails from a small image?

Yes. A picture smaller than 600 pixels is enlarged to fill the square. It cannot gain detail it never had, so a very small source will look soft.

Do my pictures get uploaded?

No. Your browser does all the resizing on your own device and saves the files straight to it. Nothing is sent to a server.
