Lossless PNG compression via re-encode — optimize file size without losing quality.
To compress a PNG file, upload your PNG image, choose a quality tier (Low, Medium, High, Maximum) or select Custom to enter an exact target size in KB. The tool re-encodes the image while fully preserving transparency — critical for logos, icons, and graphics. You can also convert the compressed output to JPEG or WebP for further size reduction. Processing runs in your browser using WebAssembly. Free, no account required, no watermarks.
Compress PNG graphics, icons, and illustrations to reduce page load times. Lossless compression preserves transparency and sharp edges.
Reduce PNG product photo file sizes while keeping quality. Faster-loading product images improve conversion rates.
Compress PNG sprites, buttons, and UI elements for mobile apps. Smaller assets mean faster installs and less bandwidth usage.
Compress PNG screenshots, diagrams, and infographics before publishing. Keep your content visually sharp while reducing load times.
Upload your PNG image using the tool above. The compressor uses lossless re-encode optimization to reduce file size without visual quality loss. You'll see a live expected size before downloading. No account required.
Yes, our PNG compressor uses lossless re-encode optimization. It removes unnecessary metadata and optimizes the compression algorithm without discarding any image data. Transparency and color accuracy are fully preserved.
Typical savings are 10-30% depending on the image. Images from screenshots and digital art tend to compress more than photographs converted to PNG. The live expected size shows you the exact reduction before you download.
No, lossless PNG compression preserves 100% of the original quality. Every pixel remains identical. The file size reduction comes from smarter encoding, not data loss.
