Edit image covers the everyday jobs: crop with aspect-ratio presets, rotate or flip, straighten a tilted shot, resize, and tune brightness, contrast and saturation. Your original file is never changed; edits apply to the copy you save. Reducing the width and height is the quickest way to shrink a file, and Compress image can then aim for an exact size in KB. For a whole folder of pictures, Batch resize changes size and format and renames the files in one go.
Remove background cuts a person out of a photo and saves it with a transparent background or a plain white or coloured one. A person-detection model runs on your device, so it works best on photos of people and may struggle with objects or pets. Pick PNG to keep transparency, because a JPG cannot be transparent, and look at the edges around hair at full size before you use the result.
Stitch images joins screenshots or photos into one picture, stacked vertically or placed side by side, with a gap, margin and background you choose. You can reorder the pictures and see a live preview before you save. It suits before and after shots, long chat screenshots and simple collages.
For a photo going into a form, a sensible order is to crop and resize first, check the file size, compress to the limit the form states, and clean the location data last. Work from a copy at full quality rather than editing a compressed file again, because each lossy save removes detail. If the form wants a passport-style photo, the passport hub has sizes by country, head-height guides and print sheets.
Related jobs have their own hubs: passport and visa photos, compressing a photo to a size in KB, and removing location data or blurring faces before you share a picture. Nothing is uploaded, so you can work on private pictures such as family photos or ID shots without a second thought. All of it is free, with no account.
