There are moments in a lot of projects where you realize:

I am solving the same little thing, over and over.

For me, that problem has always been spritesheets.

Huge spritesheets.
Weird padding.
Offsets.
Non-matching sizing.

Check the last tile's coordinates. Count over two tiles, down four.

Was that tile (12,7) or (13,7)?
Crap. I need raw pixel coordinates.
Multiply by tile size.
Account for padding.
Try again.

Repeat.

I also realized something else: for most of these massive sheets, I’m using maybe 1% of the tiles. The file size might not be huge, but it still got me thinking about how much waste there is — both in bandwidth and in mental overhead.

I didn’t spiral.

I built the tool I wanted instead.

SheetSorter (v1.0.0 Free)

I’ve launched a small utility called SheetSorter.

The first feature set — TileFinder — helps you:

• Inspect large spritesheets
• Handle padding and offsets
• Zoom and pan cleanly
• Copy tile coordinates
• Copy raw pixel source coordinates

No installs.
No accounts.
It runs in your browser (and can be installed as a PWA if you want).

If you’ve ever wrestled a giant spritesheet and just wanted clean coordinates without doing math in your head, this is for you.

Try it here:

What’s Next

This is just the foundation.

The next step (and honestly the part I’m excited about) is the full SheetSorter workflow layer:

• Select only the tiles you need
• Assemble a new optimized sheet
• Export PNG
• Export JSON manifest
• Attach metadata to tiles

Because if I’m using 20 tiles out of 500, I’d rather ship 20.

If you try it and have feedback, I’m listening.
