Compress PNG to 20KB (Quick Guide)
PNG is lossless; to approach 20 KB we reduce colors and, if needed, dimensions—processing happens locally.
1) Core idea
PNG size is controlled by palette size and pixel count. We quantize colors and, if necessary, downscale until near 20 KB.
2) Flow
- Upload your PNG (transparency preserved).
- Auto‑compress reduces palette and tries to hit ~20 KB.
- If still large, modest downscale is applied.
- Download the optimized PNG.
3) Sanity checks
- Photos don’t compress well as PNG—JPG/WebP is better for photos.
- Logos/flat graphics compress very well as PNG.
4) Shortcuts
- Limit colors in source artwork for smaller PNGs.
- Resize longest side to ~500–800 px to reach 20 KB.
5) Pitfalls
- Textured photos can exceed 20 KB even after quantization—use JPG instead.
- Excessive downscaling may blur thin lines—balance colors vs size.
6) Micro examples
- Logo 800×300 with flat colors → often 8–20 KB.
- Screenshot UI 1280×720 → may need downscale to meet 20 KB.
7) Mini FAQ
- Transparency? Preserved.
- Processing? 100% local in your browser.
- Output? PNG.
8) Action tip
For photos, try the JPG compressor pages if PNG can’t reach 20 KB without heavy downsizing.
