How to Compress Images Online

Simply drag and drop your images into the box above, adjust the quality slider to your preference, and click "Compress All". Your compressed images will be ready to download instantly — no waiting, no server upload.

For most web images, a quality setting of 70–80% gives the best balance between file size and visual quality. For images where quality is critical, use 85–90%. For thumbnails or previews, 60–70% is sufficient.

Why Compress Images?

Smaller image files mean faster websites, lower storage costs, and quicker email attachments. A single uncompressed photo can be 5–10MB — after compression, the same image can be under 500KB with no visible quality difference.

Our compressor uses your browser's built-in canvas API to re-encode images at your chosen quality level. For WebP output, you'll typically see 25–35% smaller files compared to JPEG at the same quality.

Will I lose quality when compressing?▸
