Image compressor — reduce image file size online

This free image compressor reduces the file size of JPG, PNG, WebP, and GIF images directly in your browser. You can adjust the quality level to balance between file size and visual quality. Compressed images load faster, use less storage, and help improve website performance scores.

Why compress images for websites

Images are typically the largest files on any webpage. Unoptimized images slow down page load time, increase bandwidth costs, and hurt Core Web Vitals scores (especially Largest Contentful Paint). Compressing images before uploading them is one of the most effective performance improvements you can make to a website.

Quality settings guide

  • 90–100%: Near-lossless — best for print or archiving, large file size
  • 75–89%: High quality — ideal for hero images and product photos
  • 60–74%: Good quality — standard for blog images and thumbnails
  • 40–59%: Visible compression — use for small thumbnails or previews

JPG vs PNG compression behavior

JPG is a lossy format — each compression reduces quality slightly. PNG is lossless — the quality slider controls the JPEG reencoding quality when converting PNG to a compressed output. For transparent images, keep them as PNG since JPG does not support transparency.
