Large image files can make websites slower and take up unnecessary storage space. Our free image compressor helps reduce the size of JPG, PNG and WebP images so they are easier to upload, share and use online.
Upload an image, choose your preferred output format and adjust the quality level. The compressed image can then be downloaded directly to your device.
How to Compress an Image

Click Compress Image. When processing finishes, the new file size and percentage reduction will be displayed. You can then download the compressed image.
JPG, PNG or WebP?
Different image formats are useful for different situations.
- JPG: A common choice for photographs and images where a smaller file size is important.
- PNG: Useful when transparency or lossless image reproduction is needed.
- WebP: A modern format that can provide efficient compression while maintaining good visual quality.
The exact file size you achieve depends on the original image, dimensions, format and selected quality.

Image Compression Without an API
This tool uses standard browser capabilities to read the image, draw it onto a canvas and create a new image file. The browser Canvas API supports exporting images with a selected format and, for lossy formats such as JPEG and WebP, a quality value.
This approach means the page does not require an external image compression API for the basic compression process.
Image Compressor FAQ
Is this image compressor free?
Yes. The page is designed as a free browser-based image compression tool.
Which image formats are supported?
You can upload JPG, JPEG, PNG and WebP images. The output can be created as WebP, JPG or PNG.
Can I compress images on my phone?
Yes. The interface is responsive and can be used on modern mobile browsers.
Does the quality slider work with PNG?
PNG is a lossless format, so the quality setting used for lossy JPEG and WebP encoding does not provide the same type of quality control for PNG.
Will compression always make the file smaller?
Not necessarily. The final size depends on the original format, image content, dimensions and selected output settings. Some images may already be highly optimized.
Can I use compressed images on my website?
Yes. After downloading the compressed file, you can upload it to your website or use it wherever that image format is supported.
