# heydeer/slimdeer

> A lossy PNG compressor that automatically picks the palette size and dithering for each image by scoring results with a perceptual metric, available as a CLI and a WebAssembly browser app.

## Useful for

- Compress PNG assets in a build pipeline via the CLI to cut file sizes.
- Compress images in the browser without uploading them to a server.
- Compare pngdeer output against TinyPNG or pngquant at a fixed quality target.

## Why it’s here

- Star-counter measurements on 2026-11-04 (UTC), 00:27–03:20: 431 → 432 stars (+1). This is the change over that interval.
- Estimated end-of-day forecast: about +6 stars, using observed gains and the previous day.
- The repository is 10 days old and already has 432 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 40
- Issues and pull requests: 5
- Watchers: 2
- Average over the last week: 16 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 0

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
