Shrink image file sizes for faster websites, email and uploads. Compress multiple images at once, resize them, and convert to modern WebP — without your files ever leaving your device.
How to use the Image Compressor
- Drop one or more images.
- Choose the output format, quality and maximum width.
- Compare sizes and download the compressed images.
Which format should I choose?
WebP is typically 25–35% smaller than JPEG at similar quality and supports transparency — the best choice for the web. JPEG suits photos everywhere. PNG is lossless and best for screenshots and graphics with sharp edges.
Quality setting
A quality of 75–85% usually cuts file size dramatically with no visible difference.
Frequently asked questions
Are my images uploaded?
No. Compression uses your browser's canvas, so images never leave your computer.
Is there a file limit?
No limits. Very large images depend on your device's memory.
