A fun trick I do with my web based drawing tools is to save a JSON representation of your document as a comment field inside of a PNG. This way the doc you save is immediately usable as an image but can also be loaded back into the editor. Also means your downloads folder isn’t littered with unintelligible JSON files.

Macromedia did this when saving Fireworks files into PNG.

Also, Adobe saves AI files into a PDF (every AI file is a PDF file), and Photoshop can save PSD files into TIFF files (people wonder why these TIFFs have several layers in Photoshop, but just one layer in all other software).

> Macromedia did this when saving Fireworks files into PNG. I forgot about this..

Fireworks was my favorite image editor, I don't know that I've ever found one I love as much as I loved Fireworks. I'm not a graphics guy, but Fireworks was just fantastic.

BTW. I am the author of https://www.photopea.com , which is the only software that can open Fireworks files today :D If you have any files, try to open theim (it runs instantly in your browser).

Do you have any info on the format used in the PNG chunks? I’d love for someone to recreate Fireworks, it was perfectly adapted to a lot of workflows.

You’re doing god’s work here, thanks for your service! I use photopea all the time. Probably the most impressive web app I’ve seen in terms of performance.

Proud paid Photopea user here. I can't understand how you guys overcame my mountain of incredulity but you have saved my ass so much. I was literally looking into dual booting before I found your product.

(Not many things handle .ai so well either!!)
