Arrange multiple images into fixed cells to create a sprite sheet or thumbnail contact sheet, set columns, cell dimensions, spacing, background and optional filenames, then export PNG.
What this tool does
Arrange multiple images into fixed cells to create a sprite sheet or thumbnail contact sheet, set columns, cell dimensions, spacing, background and optional filenames, then export PNG.
People often describe this task with phrases such as contact sheet maker, sprite sheet maker, image contact sheet and thumbnail sheet. This page uses those terms only where they refer to the same underlying function.
How to use the Image Sprite & Contact Sheet Maker
- Open the Image Sprite & Contact Sheet Maker page and select or enter the source data required by the tool.
- Review the available controls instead of accepting defaults blindly when the destination has a size, format, layout or compatibility requirement.
- Run the operation and inspect the preview, status or generated result before treating it as final.
- Download or copy PNG and verify it in the destination application, browser, viewer or workflow that will actually use it.
Use the interactive tool above for the actual operation. The documentation below explains what the controls mean, what changes in the file/data, and how to troubleshoot common results.

How it works technically
Raster image operations work on decoded pixel data. Dimensions, alpha transparency, color representation and encoder settings can all affect the result independently.
A contact sheet lays multiple source images onto one larger canvas in a repeated grid.
Cell dimensions define each slot; images need scaling or fitting when their aspect ratio differs from the cell.
Common use cases
- Build a thumbnail contact sheet
- Create a simple sprite atlas
- Review many images at once
- Generate a labeled visual index
Choosing the right settings
- Use consistent cell sizes for easy visual scanning.
- Enable filenames when the sheet is used as an index.
Common problems and fixes
Images look too small
Increase cell width/height or reduce the number of columns.
Labels overlap
Use larger cell height or reduce filename length.
Browser processing and privacy notes
The source code for this build performs the documented file transformation or analysis from browser JavaScript/Web APIs, and the video tools load FFmpeg.wasm for media processing. The site also contains third-party analytics, font/CDN and advertising scripts that can make ordinary network requests. Therefore, the precise claim made here is limited to the tool routine: it does not need a separate AutoClip file-upload API in order to perform the documented local operation.
For sensitive files, you should still use your browser’s developer tools or network controls if you need to independently verify the behavior of every third-party request in your environment.
Frequently asked questions
What does the Image Sprite & Contact Sheet Maker do?
Arrange multiple images into fixed cells to create a sprite sheet or thumbnail contact sheet, set columns, cell dimensions, spacing, background and optional filenames, then export PNG.
What input and output does it use?
Input: multiple images Output: PNG sprite/contact sheet Outputs include PNG.
Do I need to install desktop software?
No desktop installation is required for this page. The interactive workflow runs from the web browser. Some advanced media features load browser-side JavaScript/WebAssembly libraries when needed.
Are selected files processed through the tool interface?
Yes. The implementation reads selected files with browser APIs and performs the documented transformation or analysis in the page. External libraries, analytics and advertising scripts may make their own network requests, so this statement is about the file-processing routine itself.
Images look too small?
Increase cell width/height or reduce the number of columns.
Labels overlap?
Use larger cell height or reduce filename length.
