Why Choose Our Free Image Compressor?

Unlike other PNG compressor tools that upload your images to servers, our compressor runs entirely in your browser. This means:

  • Complete Privacy: Your images never leave your device. No server uploads, no data collection.
  • Faster Processing: No waiting for upload/download. Compression happens instantly using your browser's native capabilities.
  • No File Limits: Compress as many images as you want. No daily limits, no subscription required.
  • Works Offline: Once the page loads, you can compress images without an internet connection.
  • Precise Size Control: Target exact file sizes like 100KB, 50KB, or 20KB — not approximate ranges.

Compress PNG vs Compress JPG — Which Should You Use?

PNG is ideal for images with transparency, text, logos, and graphics with sharp edges. JPG works better for photographs and images with many colors. Our compressor accepts both and outputs optimized WebP for the best of both worlds.

Reduce Image Size for Email and Web

Most email providers limit attachment sizes to 10-25MB, and large images can push you over this limit fast. By compressing images to 50KB-100KB, you can include multiple images in a single email while ensuring fast loading for recipients.

For websites, Google recommends keeping images under 100KB for optimal Core Web Vitals scores. Our compressor helps you hit these targets while maintaining visual quality.
