PixelVault’s image cropper lets you crop an image in the browser and rotate, flip or straighten it — all without uploading. Cropping is the quickest way to improve a photo: remove distractions, focus on the subject, or reframe for a specific aspect ratio. With PixelVault you drag a selection directly on the image, and the output dimensions update live so you always know exactly what you will get.
Lock the crop to common ratios like 1:1 for a profile picture, 4:3 or 3:2 for prints, or 16:9 for video and covers — or crop freely to any shape. You can also round the corners or crop to a circle with transparent corners, and add a colored border or frame, with a live preview of the final result. Beyond cropping, you can rotate in 90° steps, flip horizontally or vertically, and nudge a crooked horizon back to level with the straighten slider. It is a focused, private alternative to bulky online editors for the edits people make most often.
How it works
The image is rendered to a canvas with your rotation, flip and straighten baked in, and the crop selection maps to exact pixels on that canvas. When you export, PixelVault copies just the selected region into a new canvas and encodes it — so the crop is pixel-accurate and the rest of the image is simply discarded.
Why local processing matters
Because cropping happens on your device, your photos are never uploaded, cached or logged anywhere. That is especially reassuring when you are trimming personal pictures, documents or screenshots that contain private details. It is instant, and it works offline.
