How do I keep the entire photograph?

Switch to Fit. The output keeps the original aspect ratio inside the requested box, so it may be narrower or shorter than 1080 × 1080. This tool does not add a padded square canvas.

Can I resize several photos together?

Yes. Add a batch to the queue and use Download all. Each file shows its calculated dimensions before export. With Fill, each image gets its own centered crop.

Will a small photo become sharper at 1080 pixels?

No. Enlarging interpolates existing pixels and cannot recover missing detail. Prefer an original image at least as large as the output you need.

This page opens on a 1080 × 1080 square with Fill selected, so a portrait or landscape photo is cropped to the center rather than stretched. For a 4:5 portrait, change the height to 1350; for a 3:4 image, use 1440. Preview the subject and edges before downloading. These are image export sizes; the posting app decides which crops appear in its different surfaces.

The aspect is unlocked, so the box can be any shape you type. Fill: Fills the box exactly, with the overhang cropped evenly off both sides. A side that works out fractional is rounded to the nearest whole pixel, and never to nothing. Saving several files at once may ask your browser for permission the first time.

Exact on the numbers, honest about the pixels. The output dimensions are exactly what you ask for, and the aspect ratio is kept unless you unlock it. Enlarging cannot add detail that was never in the picture, so an upscale is an interpolation and is shown as one. Your pictures are decoded and redrawn in this tab, never uploaded, and the only thing kept between visits is the size and mode you last used.
