How to Compress an Image

1. Upload your image — drag and drop a PNG or JPG file into the upload zone, or click to browse. Files up to 20 MB are accepted.
2. Choose compression level — Low preserves maximum quality with modest size reduction, Medium balances quality and file size, High maximizes compression for web use.
3. Preview the result — see side-by-side original and compressed images with file sizes displayed below each.

Why Compress Images?

Large image files slow down websites, increase bandwidth costs, and frustrate users. Compressing images before uploading them to your website, blog, or social media can reduce file sizes by 40-80% with minimal visible quality loss. This is critical for:

• Website performance — faster page loads improve user experience and search engine rankings
• Email attachments — stay under attachment size limits while sharing photos
• Social media — platforms compress uploads anyway; starting with a compressed file gives you more control
• Mobile users — smaller files save data and load faster on cellular connections

Compression Levels Explained

Low compression uses quality settings around 85%, ideal for print or high-quality displays where file size is less critical. Medium compression at 60% quality is the sweet spot for most web use, offering significant size reduction with barely noticeable quality loss. High compression at 35% quality aggressively reduces file size, suitable for thumbnails, previews, or situations where speed matters more than perfect quality.
