Divvy up massive images for easier processing.

Tilen allows you to convert large images into multiple smaller images called tiles, which are easier for computers to process and display. It is perfect for web, graphic and software developers with projects that require working with such large images, but need only to see small portions of them at a time.

Simply select the image you'd like to break into tiles. Then, set the desired width, height and file format of the tile images. Finally, click Save Tiles, select a destination folder, and away you go!

Tilen will save the tiles with an easy to understand naming convention based on the horizontal and vertical position of each tile. For example, a tile named x14y2.jpg would be 14th column, 2nd row tile. This logical naming convention allows effortless integration into your programming projects.


We've found Tilen to be quite capable. On a 2.66 GHz Xeon workstation with 12 GB of memory, saving a 200 megapixel TIFF image as 20,000 100x100 pixel tiles with 80% JPEG compression took one minute and 37 seconds.

Tilen may become temporarily unresponsive while saving many tiles. Do not be alarmed, it will return to life when the tiles are finished.

When working with images larger than ~200 megapixels or more than ~40,000 tiles, Tilen may behave unexpectedly!

Tilen does not recognize transparency. Transparent pixels from PNG or GIF files will become non-transparent after export. I hope to solve this problem eventually.


Tilen can save tiles in JPEG, PSD, BMP, PNG, TARGA, or SGI formats, and open many more. Tilen even lets you pick a custom extension for your saved tiles, to hide the identity of your images for use in software packages and such.


Tilen will run on Mac OS X 10.3.9 or higher, or Windows 2000 and higher. Tilen also requires Apple QuickTime to be installed. You can download it for free at

Tilen runs natively on both PowerPC and Intel Macs.
