Compress PNG to 500KB (Quick Guide)
Reduce palette and optionally downscale to keep PNGs near 500 KB—alpha preserved, no uploads.
1) Core idea
PNG size = colors × pixels. We quantize colors and resize a bit if needed while keeping transparency.
2) Flow
- Upload PNG.
- Auto‑compress trims colors to approach 500 KB.
- Downscale gently if still above target.
- Download PNG output.
3) Sanity checks
- Vector‑like art compresses well; photographs as PNG do not—prefer JPG.
- Transparency is preserved.
4) Shortcuts
- Reduce color count in source files.
- Resize longest side to ~2400–3200 px for ~500 KB results.
5) Pitfalls
- Aggressive quantization can cause banding—raise palette size a bit.
- Too much downscaling blurs UI lines—balance palette vs size.
6) Micro examples
- Logo 3000×1000 → typically 300–520 KB.
- UI 2560×1440 → small resize to meet 500 KB.
7) Mini FAQ
- Transparency? Preserved.
- Local? Yes—runs in browser.
- Output? PNG.
8) Action tip
If it’s a photo, use a JPG compressor for cleaner results under 500 KB.
