Batch mode is for when you have more than one image. If you need the same grid on a whole set of files, repeating the single-image workflow wastes time. The batch page handles that faster.
How batch splitting works
The batch tool uses one layout for every file you upload. You build a queue, pick the grid once, and export everything in one go.
- Upload several images: drag in multiple files or select them together.
- Manage the queue: add more files, remove individual items, or clear the whole batch.
- Use one shared layout: 2x2, 3x3, 4x4, or a custom row and column setup.
- Export one ZIP: each source image gets its own folder inside the final download.
- Keep it private: processing happens in the browser, not on a server.
When to use batch mode
Content calendars
If you're preparing several Instagram grids or campaign visuals, batch mode keeps the layout consistent without repeating the setup.
Product image sets
Teams working with multiple product shots can apply the same tile pattern across an entire folder and keep the output organized.
Creative asset prep
Designers, educators, and social teams often need the same split pattern for a group of visuals. Batch export handles that.
Prepare the files before opening batch mode
Batch mode is fastest when the folder is already consistent. Group files by the grid they need, remove duplicates, and rename sources before upload. The source base name becomes both the ZIP folder name and part of each output file name, so descriptive names are easier to work with than camera defaults.
- Put all 3x3 files in one run and all 4x4 files in another.
- Use unique source names so folders are easy to identify.
- Check orientation before upload; batch mode does not make individual composition decisions.
- Use the grid size calculator when identical tile dimensions are required.
How to batch split images
- Upload multiple files. Add all images that should use the same layout.
- Review the queue. Remove any file you don't want and add more if needed.
- Select the grid. Choose 2x2, 3x3, 4x4, or enter a custom layout.
- Process the batch. The tool splits each image and builds one ZIP file.
- Download the result. Open the ZIP and you'll see a folder for each source image with numbered PNG pieces inside.
One batch uses one grid. If some files need 3x3 and others need 4x4, run those as separate batches.
Tips for smoother batch exports
- Rename files before upload if you want cleaner folder names in the ZIP.
- Start with a small test batch when you're working with very large images.
- Keep every image in the batch intended for the same layout, especially on social media campaigns.
- Use the single-image splitter instead when you only need one file.
Estimate browser memory, not just file size
A compressed JPEG can be only a few megabytes on disk while requiring much more memory after the browser decodes every pixel. Batch processing also holds generated PNG data and ZIP entries during export. The practical limit therefore depends on pixel dimensions, image count, browser, device memory, and the selected grid.
Start with two or three representative files. If that test completes, increase the batch gradually. A failed large run does not mean the images are invalid; it may mean the browser cannot hold the entire job at once.
Several smaller batches are easier to retry and verify than one maximum-size batch.
Understand the ZIP structure
The final ZIP contains one folder for each successfully processed source. Inside that folder, files are numbered from top-left to bottom-right. For example, a source named campaign-a.jpg produces a campaign-a/ folder with files such as campaign-a_01.png, campaign-a_02.png, and so on.
After download, compare the number of folders with the number of source images and spot-check the first and last tile in several folders. Keep the original source folder until the export has been reviewed.
Recover from a partial or failed run
- Remove the largest files and retry them separately.
- Close other tabs or switch from a phone to a desktop browser.
- Reload the page before retrying so old canvas and ZIP data can be released.
- Use single-image mode to determine whether one specific file is damaged.
FAQ
Are the batch images uploaded anywhere?
No. Like the main tool, batch mode processes files locally in your browser.
Does each image get its own folder in the ZIP?
Yes. The ZIP is organized by original file name, which makes larger exports easier to sort.
Can I use different grid sizes in one batch?
No. The batch workflow applies one row-and-column setting to every file in that run.
Next step
Open the batch splitter if you're processing a set of files, or go back to the single-image tool when you only need one image split.
