How to Compress PNG Files Without Losing Quality

Updated June 2026 · 3 min read

PNG is lossless — by definition, you can't discard data without technically "losing quality." But there are smart ways around this.

Option 1: Lossless Compression (10-30% Savings)

Tools like pngquant, optipng, and zopfli re-encode PNG data more efficiently without changing a single pixel. This is safe for every use case — screenshots, logos, anything. The savings depend on the image: simple graphics with few colors compress more than complex photos.

Option 2: Convert to 8-bit PNG (Up to 70% Savings)

Full PNG-24 supports 16 million colors. But most logos, icons, and simple graphics don't need that many. Converting to PNG-8 (256 colors) can shrink files by 50-70% with barely visible quality loss. This is how TinyPNG works under the hood.

Option 3: Convert to Lossy Format (Up to 95% Savings)

The nuclear option: convert your PNG to JPG or WebP. For photos saved as PNG (a common mistake), this can reduce file size by 90-95% while looking identical. For screenshots and graphics with text, keep it PNG. Use our compressor and select JPG or WebP output — the before/after view helps you decide if the quality trade-off is worth it.
