Compress PNG to 100KB (Quick Guide)
Quantize colors and optionally downscale to approach 100 KB—keeps transparency, all in‑browser.
1) Core idea
PNG size depends on color palette and pixels. We reduce palette depth and resize slightly if needed.
2) Flow
- Upload the PNG.
- Auto‑compress trims colors for ~100 KB.
- Downscale modestly when necessary.
- Download as PNG with alpha preserved.
3) Sanity checks
- Flat graphics compress far better than photographic PNGs.
- For photos, JPEG/WebP targets are more size‑efficient.
4) Shortcuts
- Limit colors in the source artwork.
- Resize longest side to ~1400–2000 px for 100 KB comfort.
5) Pitfalls
- Too few colors can posterize gradients—raise palette size slightly.
- Large screenshots may require modest downscaling.
6) Micro examples
- Logo 1600×600 → typically 60–120 KB.
- UI screen 1920×1080 → downscale to meet 100 KB.
7) Mini FAQ
- Transparency? Preserved.
- Local? Yes—no uploads.
- Output? PNG.
8) Action tip
If the PNG is a photo, switch to a JPG compressor page for easier 100 KB results.
