How it works and good to know
Takes JPG, PNG, WebP, GIF, BMP, AVIF and HEIC — up to 20 files at once, 20 MB each and 100 MB in total (SVG has no fixed pixel size, so use the image format converter for it). In pixel mode with the aspect ratio locked, filling one box sets the other from the ratio, and filling both fits the photo inside that box (the longer-side presets work the same way). Unlocking the ratio stretches or shrinks to exactly the sizes you enter. The width and height you type are the size after rotation. Results can be up to 8192 px on a side and 36 megapixels, and there is an option to leave small photos from being enlarged. Large reductions are done in halving steps to keep detail sharp. The orientation stored in each photo (EXIF Orientation) is applied so it saves upright, and EXIF such as location is not kept. Save as the original format, JPG, PNG or WebP; JPG fills transparent areas with white. To hit a file size in KB use Compress Images, and to keep only part of a photo use Crop Image.
