How It Works
2
Choose available compression settings
Use the quality slider and available max-width setting to balance file size and appearance.
- Lower quality often reduces file size more, but may affect image appearance
- Compression results depend on the source image and settings
3
Start compression
Click Compress Images and wait while the browser processes each image.
- Each image is processed independently
- Some files may not get much smaller or may fail to process
4
Download the compressed image if available
Review the original and compressed file sizes, then download each available result.
- Exact final KB size is not guaranteed
- Compare the result before using it in a website, email, or upload form

Tips & Best Practices
Exact KB targets are not guaranteed
Searches like compress image to 50KB, 100KB, or 200KB are common, but this tool uses quality and size settings rather than an exact target-KB control.
Compression results vary
Images that are already optimized, very small, transparent, or highly detailed may not shrink much without visible quality changes.
Browser-based processing
Compression runs in your browser with a Web Worker, so performance can depend on your device, browser, file size, and batch size.
