Image Compressor
Compress images with adjustable quality, resize, and format conversion in your browser
How does image compression work?
This tool uses the Canvas API to re-encode your image at a specified quality level. Lower quality settings produce smaller files but may introduce visual artifacts. The process happens entirely in your browser.
Is my data safe?
Yes, all processing is done locally in your browser. No images are uploaded to any server. Your files remain completely private.
What is the maximum file size?
The maximum file size per image is 50MB. For very large images, the tool will resize them to fit within browser memory limits.
What formats are supported for output?
You can output compressed images in JPEG, WebP, or PNG format, or keep the original format. WebP typically offers the best compression ratio.
Does compression reduce image dimensions?
Only if you set a maximum width or height. By default, the tool only adjusts the compression quality without changing dimensions. Aspect ratio is always preserved.
