What this workspace does
Evenly cut local image slices in a ZIP.
Image layout · browser local
Split one image into an exact grid.
Choose column and row counts, preview the cell plan, and download all slices together as a named ZIP.
Use it accurately
Slices use source pixels. If the dimensions do not divide evenly, the final row or column absorbs the remaining pixel.
Private browser processing
Selected files are processed in the current browser session. Aftermath has no account, cloud file storage, or server-side file-processing job.
How to use this tool
Split one local image into a chosen grid when you need numbered image slices in a ZIP. The browser creates the slices from the selected file and keeps the source in the current session. Review the slice order, dimensions, and any destination-specific carousel or grid requirements before publishing or uploading the results.
What to choose and what you get
What to choose
- one supported local image
Result
- a ZIP containing numbered image slices
Supported formats
- Accepted formats: JPG, PNG, WebP.
- Output formats: ZIP, PNG.
Browser support and permissions
- Modern browser with JavaScript, a supported image decoder, and enough memory for the selected image.
- No camera, microphone, or screen permission is needed.
Worked example
A 2400 × 1600 artwork needs six equal files arranged as three columns by two rows.
Starting facts
- The source dimensions divide evenly for the chosen grid.
- Numbered output order must remain unambiguous.
Observed operation: Choose three columns and two rows, split the decoded canvas locally and package the six numbered slices in a ZIP.
Review the result: Inspect the slice dimensions, edge continuity and numbering before using the extracted images.
Boundary: A regular grid does not identify semantic objects, safe crop boundaries or the posting order required by another platform.
Check your result
- Slices use source pixels. If the dimensions do not divide evenly, the final row or column absorbs the remaining pixel.
Things to know
- Review the result on the intended device before relying on it.
Privacy boundary
The selected image stays in the current browser session and is not sent to an Aftermath processing service. How local processing is verified.
What this tool verifies
Checks the displayed limits and reports or creates a ZIP containing numbered image slices from one supported local image.
