What is Image Compression?

Image compression is the process of reducing an image's file size by removing redundant or non-essential data. There are two types: lossless compression (no quality loss, smaller savings) and lossy compression (small quality loss, significant savings). Fimusk uses intelligent lossy compression optimized to be visually identical at 70–90% quality settings.

For websites, smaller images directly improve your Google Core Web Vitals score (especially LCP — Largest Contentful Paint), which is a confirmed Google ranking factor. Compressing your images before uploading to your site is one of the easiest performance wins available.

Why Compress Images?

  • Faster websites: Smaller images load faster, reducing bounce rates and improving user experience.
  • Better Google rankings: Page speed is a ranking factor. Compressed images directly help your SEO.
  • Lower bandwidth costs: Serve fewer bytes to your visitors, especially on mobile networks.
  • Email attachments: Compress before attaching to stay within email size limits.
  • Social media: Platforms like Instagram, WhatsApp, and Twitter re-compress your images. Upload already-compressed files for better quality control.
  • Storage savings: Reduce disk usage on your phone, server, or cloud storage.

Supported Image Formats

Our free image compressor supports the three most common image formats on the web:

  • JPG / JPEG — Best for photos and complex images with many colours.
  • PNG — Best for graphics, logos, and images with transparency.
  • WebP — Google's modern format, excellent compression with high quality.
