Why Compress Images?
Large images slow down websites, fill up storage, and make sharing difficult. Compression reduces file size while maintaining acceptable visual quality.
For web use, compressed images load faster, improving user experience and SEO rankings. For email, smaller images ensure your messages send successfully.
This browser-based compressor works entirely on your device. Your images remain private — nothing is uploaded to any server.
Compression Settings Guide
90-95% Quality: Minimal compression, near-original quality. Use for print or archival purposes.
80-85% Quality: Excellent balance for general use. Visually excellent with significant size reduction.
70-75% Quality: Good quality with strong compression. Suitable for web thumbnails and previews.
50-65% Quality: Maximum compression with visible artifacts. Use when file size is critical.
Tips for Best Results
Start with the highest quality source image. Compression cannot improve quality, only reduce file size.
Resize oversized images before compressing. A 4000px image displayed at 800px is wasteful even when compressed.
Test different formats. WebP often produces smaller files than JPG at equivalent quality.

How much can images be compressed?
Depending on the original and settings, images can be reduced by 50-90%. A 5MB photo might compress to 500KB-1MB while maintaining good visual quality.
