Piskel (Transparency Fork)

Try Online

Warning

This isn't the real piskel! For the real one visit https://www.piskelapp.com

This is a fork of Piskel that adds full RGBA transparency support. It was almost completely done with AI, so I don't feel comfortable making a PR/issue, but feel free to clone it down and play with it yourself!

Differences from the real Piskel

• Semi-transparent pixels throughout the editor (import, edit, render)
• Alpha slider in the color picker
• Transparency tool (I) to incrementally add/remove transparency from pixels

Limitations

• No GIF support

• jszip : create, read and edit .zip files with Javascript
• canvas-toBlob : shim for canvas toBlob
• jquery : used sporadically in the application
• bootstrap-tooltip : nice tooltips
• playwright: End to end testing

As well as some icons from the Noun Project :

• Folder by Simple Icons from The Noun Project
• (and probably one or two others)
