Rotate image the right way up, no quality lost

No. Turns by 90° and 180° move the compressed blocks of the JPG without decoding it. When the picture size does not fit the JPEG block grid, the turn is written into the EXIF orientation tag instead, which is also lossless and is followed by phones, browsers and photo apps.

For JPG photos, not when it can be avoided: turns, flips and crops are done on the compressed data, like jpegtran, so nothing is compressed again. For that, the top-left corner of a crop may move by up to 8 pixels to the JPEG block grid. Straightening, exact pixel sizes and circles need new pixels, so those are saved again at high quality (92 by default).

Drag the Straighten slider under the photo, up to 45° either way, in steps of a tenth of a degree. A fine grid helps you line up the horizon, and the crop shrinks so no empty corners are left.

Yes. Add many files or a whole folder: every photo gets the same ratio, size, rotation and format, with the crop in the middle. Open any photo in the strip to move its crop, then save them all as a ZIP.

Pick a ratio or a social media size, move the box where you want it, and under Output size choose Exact size and type the width and height in pixels. The crop is resized with a sharp filter to exactly those pixels. To cut an exact number of pixels from the photo without resizing, type them under Crop size.

By default the EXIF data (date, camera, settings) is kept and the picture is turned the right way up. You can remove just the location, or all metadata, in the settings.
