PNG is lossless — great for screenshots, logos, and graphics with sharp edges. But lossless also means larger files. Compressing a PNG usually means re-encoding with smarter settings or switching to a format better suited for photos.
Three ways to shrink a PNG
- Re-export as PNG with optimization (strip metadata, tune compression level).
- Convert to WebP for the web — often 25–35% smaller at similar visual quality.
- Convert to JPG if the image is a photo without transparency.
Compress in your browser with Converty
Image conversions run client-side when possible, so your file stays on your device until you download the result. Upload a PNG, pick WebP or JPG, adjust quality if needed, and download — no account required.
Choosing the right target format
- Keep PNG for UI assets, icons, and images that need transparency.
- Use WebP for hero images and blog graphics on modern browsers.
- Use JPG for photographs where transparency is not required.
How much quality can you lose?
Lossy formats (JPG, WebP at lower quality) trade file size for imperceptible changes. Start around 80–85% quality for photos. For screenshots with text, prefer PNG or high-quality WebP so edges stay crisp.
