Smaller images, same picture. Compress PNGs to PNG or WebP with automatic quality. PNG output is 8–12% smaller than TinyPNG at equal quality on the median image. Command line and browser.

About the project

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.

1.1 Cooling Magnitude out of 10 — how fast interest is growing, not a quality score.

Star growth looks organic. Data as of November 4, 2026, 03:24 UTC.

The star-growth assessment does not verify whether the project is safe to run.

Stars per day

0100200October 25, 2026November 4, 2026

Bars show stars per UTC day; the line is a moving average of available history. Gaps mean missing data, not zero growth. Today's bar is incomplete. Red marks spike days.

Why it’s trending

  • 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.

Measured growth: the last 7 completed days

New stars over 7 days: 148.

Star trust

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.

These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
