Best free PNG compressor tool to compress PNG file to 47KB 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. You can compress your images down to as low as 47KB per file while maintaining sharp detail. After uploading, our tool not only compresses your PNGs but also automatically converts them to modern WebP format, reducing sizes by up to 90% while keeping transparency for graphics, logos, and icons. Use our adjustable quality slider (1–100%) to fine-tune compression, click “Compress,” and download instantly — all processing stays on your device.
Unlike other PNG tools with file size caps, daily limits, forced signups, or paywalls, our compressor is 100% free and unlimited. You can compress and optimize hundreds of PNGs — even to exact targets like 47KB per image — without creating an account. With automatic WebP conversion, your files become faster-loading and web-ready with no visible quality loss. Since everything runs locally, it’s faster, safer, and completely private.
Perfect for web developers, designers, e-commerce stores, marketers, and photographers. Developers can reduce assets for faster websites, designers can optimize transparent logos and icons, and businesses can create lighter banners and ads for email and social campaigns. Anyone can easily compress PNGs to 47KB for social media, cloud storage, or email — no software needed, just upload and download.
Unlike most online compressors, we never upload your files to a server. Every compression and WebP conversion is performed locally using advanced in-browser technology. Your images remain 100% private — no one, not even us, can see them. It’s as secure as offline software, but far more convenient and faster.
