How Does PNG Compression Work?

PNG is a lossless compression format, meaning it reduces file size without discarding any image data, preserving the original quality perfectly. It's ideal for graphics with sharp lines, text, or transparency (like logos or illustrations). Our tool uses algorithms to efficiently encode the image data into a smaller PNG file.

  • Analyzes pixel data for patterns and repetition.
  • Uses filtering and DEFLATE compression to represent the data more compactly.
  • Preserves all original pixel information and transparency.
  • The 'Quality' setting may have less impact compared to JPG, as the focus is on lossless reduction. Target size aims to optimize encoding.

Why Compress PNG Images?

Even though PNG is lossless, compression is still beneficial:

  • Faster Website Loading: Smaller PNGs still load faster than unoptimized ones.
  • Save Bandwidth: Reduces data transfer for both you and your visitors.
  • Save Storage Space: Efficiently store more images on your devices or servers.
  • Easier Sharing: Smaller files are easier and faster to share via email or social media.

How to Use the PNG Compressor

  1. Drag and drop your PNG file onto the designated area, or click to select a file from your device. Add up to 20 files.
  2. Adjust the desired Quality and Target Max Size (MB) settings (optional). Lower quality generally means smaller files.
  3. Click the "Compress Pending" button to start processing the files marked as 'Pending'.
  4. Wait for the compression process to complete for each file (status will update).
  5. Download individual compressed files using the "Download" button next to each completed file.
  6. Optionally, click "Download All" to get a ZIP file containing all successfully compressed images.
  7. Use the "Remove" button to exclude specific files or "Clear All" to start over.
