Free image compressor

Compress PNG files and resize them in the browser.

Mirown PNG Compress keeps PNG output and helps reduce file size where browser image processing can help. PNG is common for screenshots, transparent graphics, UI assets, and clean artwork.

Because browser PNG export does not expose the same quality controls as JPG or WebP, the biggest PNG reductions usually come from resizing dimensions or scaling percentage.

How to use PNG Compress

  1. Choose one or multiple PNG images from your device.
  2. Move the Quality Control compress slider from Less to Extreme until the file size and preview feel right.
  3. Set width, height, maintain aspect ratio, or scale the image by percentage.
  4. Open the comparison view to check original size, compressed size, and reduction percentage.
  5. Download one compressed image individually or download a ZIP when compressing multiple images.

What this free tool includes

  • PNG upload
  • Resize width and height
  • Maintain aspect ratio
  • Scale by percentage
  • Before and after size comparison
  • Batch compression
  • Download individual PNG or ZIP

A large PNG screenshot or transparent graphic.

Result

Best uses for PNG screenshot

  • Best for screenshots, UI graphics, transparent images, diagrams, and clean artwork.
  • PNG files often shrink most when dimensions are reduced.
  • If a PNG is already optimized, size reduction may be small without resizing.

Before you download

  • Compare the preview and file size before replacing your original image.
  • Keep the original image until the downloaded version has been checked.
  • Use the correct format for your final destination: JPG for photos, PNG for transparency, and WebP for modern web performance.
When should I use PNG Compress?

PNG Compress is useful when a PNG screenshot is too large, has the wrong dimensions, or needs to fit a specific website, social, upload, or sharing requirement.

Will PNG Compress keep the same quality?

Quality depends on the format and settings. Resizing and cropping change dimensions, while compression can reduce visual detail. Always preview important images.
