Crop, resize and rotate tools

Geometry tools change the shape and the size of an image, never its colors. Crop cuts a rectangle out of it, resize scales the whole picture to new pixel dimensions, and change canvas size moves the picture inside a larger or smaller frame without scaling it - that is the difference between resizing the artwork and adding space around it. Change aspect ratio forces new proportions, and trim empty space removes the transparent or uniform border a screenshot came with.

Rotation comes in two forms. The 90, 180 and 270 degree turn moves every pixel exactly, so nothing is resampled and nothing gets blurry - that is the one to use for photos. A free rotation takes any angle, and any angle other than a right one has to interpolate the pixels it lands between, which softens the edges slightly. Flipping mirrors the image horizontally or vertically instead.

The remaining tools place and repeat. Padding and a border add space and a frame, zooming scales up around the center, shifting moves the picture inside its canvas, tiling repeats the image as a pattern, and splitting cuts it into parts - rows, columns, or a grid - which is the way to export a long screenshot or a contact sheet as separate files.

Tools in this category

Add border to PNG Draws a colored frame of the chosen thickness around the image. 01 Fit PNG onto background Places the image centered on a canvas of the given size with a transparent or colored background. 02 Change canvas size Sets the exact canvas size: overflow is cropped, missing space is filled with transparency. Anchor picks which part of the image stays. 03 Resize PNG online Scales the image with bilinear interpolation. With aspect kept, one side defines the scale; if both are set, the image fits inside them. 04 Crop PNG online Cuts out a rectangular area. Coordinates and sizes may go beyond the image — the area is clipped to the intersection. 05 Rotate PNG Rotates by 90°, 180° or 270° clockwise without quality loss. 06 Flip PNG Mirrors horizontally or vertically without quality loss. 07 Add padding to PNG Expands the canvas on all sides by the chosen number of pixels. 08 Tile PNG Repeats the image in a grid of the chosen columns and rows. 09 Split PNG into parts Divides the image into a grid of equal-sized parts. The canvas is padded with transparency to keep every part the same size. 10 Center PNG by content Finds the opaque part of the image and centers it on the original canvas. 11 Skew PNG Shifts content horizontally and vertically — a perspective effect. 12 Rotate PNG by any angle Rotation by any angle. The canvas grows to fit the new bounds; corners stay transparent. 13 Zoom PNG Magnifies content toward the center. The canvas keeps its size — edges are cropped. 14 Trim empty space from PNG Crops transparent borders around the content. Pixels with alpha above the threshold count as content. 15 Change PNG aspect ratio Fits the image into a target aspect ratio: crop the center to fill, or pad with transparency. 16 Swap image orientation Rotates the image by 90° when its orientation differs from the target — landscape becomes portrait and back. Square images are untouched. 17 Make a symmetric copy Doubles the canvas by mirroring the kept side onto the empty half — instant symmetric pattern. 18 Shift PNG Moves content by the given X and Y offset. 19
