Compress Image Online — Complete Guide

Reduce image file size for faster websites, emails, and app uploads while keeping acceptable visual quality. PdfPeaks lets you tune compression presets from maximum quality to aggressive savings.

How It Works

Upload an image, pick a quality preset or slider, and compress. Compare original vs output size on screen, then download the lighter file. Ideal before attaching photos to tickets or publishing blog posts.

  • Step 1 — Upload: Select JPG, PNG, or other supported image.
  • Step 2 — Quality: Choose preset — start with High for photos.
  • Step 3 — Download: Save the compressed image.

Security & Privacy

Files are encrypted in transit and deleted after processing — see our Privacy Policy for details.

Common Use Cases

  • Blogs: Improve page load and Core Web Vitals.
  • Support tickets: Attach screenshots under size limits.
  • Mobile apps: Shrink user-generated content uploads.
  • E-commerce: Batch-optimize catalog photos.
  • Storage: Reduce cloud backup usage.

Tips for Best Results

PNG with transparency may need higher quality settings than JPG photos. Convert format with Convert Format if needed. For PDF output, see how to compress images without losing quality.
