Crop, resize and export photos

Frame the photo first, then export it, or a whole series, at the size and with the names you need.

Crop and straighten

Open the photo in Develop and press R, or choose View › Crop.
Choose an aspect ratio: Free, Original, 1:1, 4:3, 3:2 or 16:9. Original keeps the shape of the photo. Press X to swap landscape and portrait, and A to lock or unlock the ratio.
Drag the edges or corners of the frame, or drag inside it to move it.
If the horizon is tilted, move the Straighten slider, from −45° to 45°, or type the angle.
Press Enter to apply and close the tool. Escape during a drag undoes that drag.

To turn a photo by 90°, use Photo › Rotate Left or Rotate Right. Edit › Undo takes back a crop step like any other change, and the Reset button of the crop tool removes crop, rotation and straightening together.

Choose what to export

In Develop, export works on the photo you are editing. In the grid, it works on the selected photos: pick the ones you want, use the filter to show only picks, then Edit › Select All, or select photos with Shift-click and Ctrl-click (Cmd-click on a Mac). Then choose File › Export…, or press Ctrl+Shift+E (Cmd+Shift+E on a Mac).

Set the size and quality

Image Format is JPEG. Quality goes from 1 to 100; higher means larger files and fewer artifacts.
Resize to Fit keeps the full size, or fits the photo to a long edge, a short edge, a width and height, a number of megapixels or a percentage.
Don’t Enlarge keeps photos that are already smaller than the target at their own size.

For a website or a message, a long edge of 2048 pixels at quality 80 is a sensible start. For printing, keep the full size and a high quality.

Name the files

Rename To builds each name from the original file name, your own text, the date or a sequence number, such as Wedding-001.jpg. The dialog shows the first names before you export. When two files of a series would get the same name, the later ones get -2, -3 and so on.

Choose where the files go

Folder. In Chrome and Edge on a computer, choose a folder, and optionally a subfolder. Existing Files decides what happens when a file of that name is already there: ask, choose a new name, overwrite or skip. White Room reads each file back after writing it, and the report marks it as saved.
Downloads. In other browsers, two or more photos go as one ZIP file, or, for up to 20 photos, as separate downloads. Your browser may ask before it allows several downloads.
Share. On a phone or tablet, send the files to the share sheet instead.

Follow the export

Photos export one after another in a queue that shows its progress. You can pause, resume or cancel it. If a file fails, the report says why, and Retry Failed tries those files again. A ZIP file or a set of downloads waits in the report until you take it.

Exported files carry no metadata from the original: no camera data and no location. White Room never changes your original files; keep them, because the copy in your browser can be cleared.
