About this tool
Reduce the size of JPEG, WebP, and PNG images directly in your browser. Choose the desired quality for JPEG and WebP files; PNG files are saved again mainly to remove unnecessary metadata. Process several images together, compare the original and resulting sizes, and download the files individually or in a ZIP archive.
Features
- Adjustable JPEG and WebP quality from 1 to 100
- Save PNG files again and remove unnecessary metadata
- Process several images at once
- Compare file sizes before and after compression
- Download several results in a ZIP archive
How to use
- Add images: Choose one or more JPEG, PNG, or WebP files.
- Choose the settings: Select the output format and, for JPEG or WebP, the desired quality. Remove metadata when needed.
- Compress and download: Review the resulting sizes and download the files individually or in a ZIP archive.
Examples
- Reduce large page images to improve loading time
- Meet email attachment size limits
- Optimize several product photographs for an online shop
- Remove GPS information before sharing photographs
Limitations
- PNG uses lossless compression, so reductions mainly come from removing metadata and saving the file more efficiently
- Very large images must be loaded into browser memory during processing
- The uploaded images are processed directly in your browser and are not sent to a server.
FAQ
- How do JPEG and WebP quality settings differ?
- Both use the selected quality setting. WebP often creates a smaller file at a similar visual quality in current browsers.
- Why did my PNG file remain almost the same size?
- PNG is saved without lossy compression. Photographs usually become much smaller when converted to JPEG or WebP.
- Does removing metadata change the image pixels?
- Saving a JPEG or WebP again can slightly alter individual pixels. For PNG, the tool mainly removes additional metadata.
