Online Image Compressor

You've probably noticed that images from your phone can be 3MB or more. That's fine for printing, but it's way too much for a website. Every unnecessary kilobyte means slower loading and more visitors hitting that back button before your page even shows up.

Here's what actually happens when you compress an image: the computer looks at areas of similar color — like a blue sky or a blank wall — and simplifies them. With JPEG, you won't notice the difference at 80% quality, but the file might be 80% smaller. That's a trade worth making.

PNG is a different story — it keeps every single pixel exactly as it was. Great for screenshots and logos where any quality loss would be obvious. WebP? That's Google's attempt to get the best of both worlds, and honestly, it works. Same quality, half the size.

Quick tip: Always keep one untouched original somewhere. Not because you'll need it every time, but because the one time you throw it away will be the time you realize you need it.

  • Use JPEG for photographs (85% quality), PNG for graphics with text, WebP for best web performance
  • Batch compress multiple images by uploading them all at once
  • Always keep your original files before compressing
  • For print materials, use high quality (90-100%) compression

How to Use
