About the Slice Tool
The slice tool cuts one picture into several images. Drag boxes over the parts you want, each one becomes a numbered slice, and the numbers are shown on the picture. Or press Replace with a grid to cut the picture into an even grid of columns and rows in one step. When the slices look right, download them all as a ZIP, each as a PNG or JPG at the picture's own resolution, named slice-01, slice-02 and so on in reading order from the top left. Use it to cut a design into pieces, split a long screenshot, make the tiles for a puzzle or a carousel, or save several items from one scan. Your picture stays in your browser.

Slices by hand or by grid
Drawing slices by hand is best for uneven parts, such as the header, body and footer of a web page design, or the separate photos on a scanned page. A grid is best for equal parts, such as the nine tiles of a social media grid or the pieces of a puzzle.
Good uses
- Cutting a long screenshot into pages.
- Making a 3 by 1 carousel or a 3 by 3 profile grid from one large picture.
- Cutting a web layout into images for buttons and banners.
- Saving several items from one scan as separate files.
- Making sprite sheets or tile sets into single images.
Reading order and names
The slices are sorted by the top edge and then by the left edge, so the first one is at the top left and the numbering reads like a page. The numbers drawn on the picture match the file names, which makes it easy to know which file is which.
PNG or JPG
PNG keeps every pixel exactly and keeps transparency, so it is the safe choice for graphics, screenshots and anything with sharp edges. JPG is smaller for photos. When you save slices as JPG, a transparent area becomes white.
Phone and computer
Draw with a finger or the mouse. The ZIP downloads to your usual folder, and on a phone most file apps can open it. Very large pictures are limited to about 16 million pixels so that slicing stays quick. Slicing helps with web pages and image grids. Use the Image Splitter for equal tiles, Crop Image for one area, and Create ZIP File to bundle all the pieces.

Frequently asked questions
How do I slice a picture?
Drag a box over each part you want as a separate image. Each box is a slice. When you are done, press Download slices as ZIP.
How do I cut it into an even grid?
Type the number of columns and rows and press Replace with a grid. Any slices you drew are replaced by the grid, which covers the whole picture.
How are the files named?
slice-01, slice-02 and so on, ordered from top to bottom and then left to right by each slice's top left corner. With 100 or more slices, three digits are used.
Is quality lost?
PNG slices are exact copies of the pixels. JPG slices are compressed, so use PNG when you need perfect quality or transparency.
Can slices overlap?
Yes. Each slice is cut from the original picture, so overlapping slices are fine.
How small can a slice be?
Slices need to be at least 2 pixels wide and tall, and are cut at whole-pixel positions.
What if the grid does not divide evenly?
The cut lines are rounded to whole pixels, so some slices are one pixel larger than others.
Is my picture uploaded?
No. The slices and the ZIP are made in your browser.
