About this tool
Compress image tries to reduce an image file size with browser canvas by changing format and quality without uploading the file.
How to use
- Select a PNG, JPG/JPEG or WebP image.
- Review the original size and dimensions.
- Choose JPG, WebP if available, or PNG when you need to preserve sharpness/transparency.
- Adjust quality for JPG or WebP.
- Compress the image and check whether it reduced or increased before downloading.
Use cases
- Lower the weight of a photo before sharing it.
- Try WebP for website images.
- Generate a lighter JPG version when transparency is not needed.
Limits
- Reduction is not guaranteed: it depends on the original format, content and browser.
- It does not resize images; original dimensions are preserved.
- Maximum image size: 15 MB.
