PNG Compression
PNG (Portable Network Graphics) is a lossless image format that supports transparency, making it ideal for logos, graphics, and images with transparent backgrounds. However, PNG files can be quite large, which is where compression becomes essential.
Our PNG compressor offers two compression modes: lossy and lossless. Lossy compression reduces file size more dramatically by removing some data, while lossless compression maintains perfect image quality but with less size reduction.
Why Compress PNG Images?
PNG files, especially those with high resolution or many colors, can become very large. Large file sizes lead to slower website loading times, increased bandwidth usage, and storage concerns. Compressing PNG images helps you:
• Improve website performance and loading speed
• Reduce storage space requirements
• Save bandwidth costs
• Enhance user experience on mobile devices
• Maintain transparency for web graphics and logos
Lossy vs Lossless Compression
Lossless compression reduces file size without any quality loss. This is perfect when you need pixel-perfect accuracy, such as for screenshots, diagrams, or images that will be edited further. The compression ratio is typically lower but image quality remains identical.
Lossy compression achieves much greater file size reduction by selectively discarding some image data. The result is visually similar to the original but with a smaller file size. This works great for photographs and complex graphics where minor quality differences are imperceptible.
How to Use Our PNG Compressor
Using our online PNG compressor is simple and requires no software installation. Start by uploading your PNG files through the upload button or by dragging and dropping them into the designated area.
Choose your compression mode: select "Lossy" for maximum file size reduction or "Lossless" to preserve exact image quality. Adjust the compression level slider to control how much compression is applied. Higher values mean less compression and better quality.
Click the "Compress Image" button and wait for the process to complete. You'll see a side-by-side comparison of the original and compressed versions, along with file size information and compression percentage.
Once satisfied with the results, download your compressed PNG file. The transparency in your images is always preserved, regardless of the compression mode you choose.
Privacy and Security
Your privacy is important to us. All image processing happens directly in your browser when possible, meaning your files never leave your device. For advanced compression, files are processed on our secure servers and automatically deleted after 60 minutes. We never store, share, or use your images for any purpose.
Our compression tool is completely free to use with no registration required. There are no hidden fees, watermarks, or limitations on the number of images you can compress.
