More details are available in this guide: Pyxel Edit activation guide

Can I run Pyxel Edit under Linux?

The 32 bit version does reportedly work well using Wine on Linux, but the 64 bit version does not. See
The 32 bit version is available for download on your license page on this site.

I have to re-enter my license key each time I start the program

It's likely that the application isn't able to store the license to file because of permission issues. Check permissions for the ELS folder or try removing it.
Windows: C:\Users\[username]\AppData\Roaming\PyxelEdit\ELS or similar. You can enter %appdata% as the path in windows explorer to find the Roaming folder quickly.)
Mac: /Users/[username]/Library/Application Support/PyxelEdit/ELS or similar. Open Finder, then choose Go>Go to folder... from the menu to be able to enter the path.

I didn't get an email with a link when I bought Pyxel Edit, what should I do?

You should have received two emails from Humble, one confirmation and one with a link to your download page on Humble. If you are using Gmail, please check the "Promotions" tab if you have it activated, as the mail tends to end up there.
Then use this page to try sending the email again:

If the resender above doesn't work you might have entered the address incorrectly, please send an email to for assistance.

Can I use the program on multiple computers?

Yes, you may use it on multiple machines owned by you, for example a desktop computer and a laptop.

When will Pyxel Edit be finished?

There's no set date for version 1.0. At the moment I'm working and very busy, so work goes in bursts when I have free time.


Pyxel Edit won't start, or just shows a gray screen. What should I do?

Try the following:

Delete the application storage directory to fully reset the application in case some settings got corrupted:

Windows: C:\Users\[username]\AppData\Roaming\PyxelEdit or similar.
You can enter %appdata% as the path in windows explorer to find the Roaming folder quickly.

Mac: /Users/[username]/Library/Application Support/PyxelEdit or similar.

If you are on Windows and use the AIR installer version, you could try the portable version which works better for some users.
Make sure you have updated to the latest version of Adobe AIR.

The Air installer says the file is damaged?

This is a strange error that happens for some users. It seems to be semi-random and suddenly work after a couple of tries.
Try the following:
- Move the air installer to the desktop and run it from there.
- Run the installer as admin.
- Shut down the Adobe updater.
- Disable the firewall
- Disable real time scanning
- Reboot

How can I change key bindings?

There is no UI for this yet (it's coming), but you can edit pyxelconfig.json in the Settings folder in the application folder to change key bindings manually.

How can I resize the image?

To resize or scale a non-tiled (single tile) image, use Document>Resize tiles...

How can I load tilemaps from Pyxel Edit in my game?

This differs between engines, languages and file formats. There are some example snippets for JSON on the Pyxel Edit GitHub repo:


Does Pyxel Edit support other tile shapes than rectangular, such as isometric or hexagon?

Does Pyxel Edit have support for indexed color modes?

No, Pyxel Edit supports full 32 bit ARGB color. The means the Palette is not a "hard" palette, you may use any other color in your images.


  • Paypal is not working for me is there another way to buy this program.
  • If I bought the app via PayPal previous to the release via Humble Widget, is there any way, short of buying it again, to get my key added to my Humble library?

    The way it is now works well enough but I really like the ease of just accessing the downloads to all my apps and games over my library.

    Don't fret if it ain't possible, I still love the heck out of Pyxel Edit.

    I got my license from Humble Bundle. I put the activation code from the page on the Activation field in the application, but every time I close it, it asks me for the code again when I open it.
