Best free PNG compressor tool to compress PNG file in high quality
(No signup, unlimited downloads,
and
always free.)
Our free PNG compressor is designed to deliver ultra-light, web-ready images without compromising quality. Simply upload one or multiple PNG files directly from your device — no size or quantity limits. After uploading, our tool not only compresses your PNGs but also automatically converts them to modern WebP format when possible, which is up to 90% smaller while keeping full transparency for graphics, logos, and icons. Use our adjustable quality slider (1–100%) to fine-tune compression and click “Compress.” Everything runs locally in your browser, so your files never leave your device and the process is lightning fast. Download optimized files individually or all at once in a convenient ZIP package.
Most online PNG tools come with heavy restrictions — file size caps, daily limits, forced signups, or paywalls. Our compressor is completely free and unlimited. You can compress and optimize hundreds of PNGs without ever creating an account. With automatic WebP conversion, your images are web-optimized and load faster without noticeable loss of quality. Because all processing is done locally, our tool is faster, private, and more secure than any server-based alternative.
This tool is perfect for web developers, designers, e-commerce businesses, marketers, and photographers. Developers can reduce asset sizes for faster-loading websites, designers can optimize transparent PNGs and logos without losing quality, and marketers can create smaller banners and ads for emails and social media. Casual users can quickly compress PNG photos for sharing, messaging, or storage — no software to install, just upload, compress, and download instantly.
Unlike most online compressors, we never upload your files to a server. All compression and WebP conversion happen in your browser using cutting-edge technology. Your files remain 100% private — no one, not even us, can see or access your data. It's as secure as using offline software but far more convenient and faster.
