IMAGE SPLITTING GUIDE

How to split an image into clean, even tiles.

Use a grid, strips, or carousel panels to turn one picture into a set of smaller images. This guide explains the settings and what to expect from your downloads.

What an image splitter does

An image splitter divides a single picture into multiple rectangular images. Set the number of rows and columns, and each tile is cropped from the matching area of the original. The pieces are numbered from left to right, then top to bottom.

Choose a layout

• Grid: split into rows and columns, such as a 3 × 3 contact sheet.
• Horizontal: create stacked strips across the image.
• Vertical: create side-by-side strips.
• Carousel: make a horizontal sequence of panels for a swipeable post.

Each direction accepts between one and ten divisions. The complete grid must contain at least two tiles and no more than 100.

How tile sizes are calculated

Image dimensions do not always divide evenly. For example, a 1001-pixel-wide picture cannot be split into three equal integer widths. The splitter distributes the extra pixels across adjacent tiles. That keeps every original pixel covered once, without gaps or overlaps. A few tiles can therefore differ by one pixel.

PNG or JPG?

Choose PNG to preserve transparency

PNG keeps transparent areas and is useful for logos, illustrations, and graphics with sharp edges. PNG files can be larger than JPG files.

Choose JPG for a smaller photographic file

JPG is suitable for photos. It does not support transparency, so transparent areas are filled with white. JPG uses lossy compression, which can slightly change image detail.

File support and device limits

ImageSplitterTool accepts JPG, JPEG, PNG, and WebP files up to 25 MB. It also limits decoded images to 40 megapixels to help prevent unusually large images from exhausting browser memory. If your device cannot process a picture at these limits, try a smaller version or generate fewer tiles.

Privacy and local processing

Your selected image is decoded, split, previewed, and exported in your browser. The image, its filename, and EXIF metadata are not sent to our servers. Optional Google Analytics measures anonymous product events only after you allow analytics. Those events do not include the image, filename, or file path.

Reset the tool or replace the image to remove its preview and temporary download references from the page. Closing the page releases the browser resources used by the tool.
