Tiled Maps Optimizer

Hi everyone,

Not sure if here’s the proper category to drop this but I just wanted to share this small tool I’ve created:
It’s basically I Tiled JSON maps and tileset images optimizer.
If you use Tiled (https://www.mapeditor.org) to create maps for your games, and you are using small parts from multiple big images, then you can use this tool where you can upload a Tiled export JSON file, along with the tilesets images, and you will get a single merged image with only the tiles used, and a new JSON file with all the tiles in layers fixed to use that merged image.

Here you have some screenshots:

Hope you like it, I would love some feedback or any comments if you have any issues.

Hey! I may not personally use this any time soon, but THIS SOUNDS GREAT!

I know how cool it is to build small or even inventive tools that help other people out. Thanks for a very interesting tool!

Hi everyone,

Here’s a video showing how the optimizer works since now it will also consider the defined animations on the map:

Hope you like it!

Does this have a github?

Yes, is a small project done in PHP, don’t expect much :sweat_smile:

I’ll try to package it at some point, but I don’t have much time now.


  • Included a resize feature, ideal for people working in for example 16x16 and want to move to 32x32, or 64x64, just specify the multiplier and that’s it!
  • Changed the repository name (will package it and make it available in composer soon): https://github.com/damian-pastorini/tiled-map-optimizer
