Compress images without uploading them
Reduce JPG, PNG or WebP image size directly in your browser. Choose WebP for efficient web delivery, JPEG for broad compatibility, or keep the original format when it suits the source.
How to use Image Compressor
- Choose up to five images.
- Select output format and quality.
- Compress the images and download one result or a ZIP for a batch.
Balance image quality and file size
Start near 80% quality. Photographs usually compress best as WebP or JPEG, while graphics that need transparency should use WebP or PNG. Always compare the result with the original.
Frequently asked questions
Are my images uploaded?
No. Decoding, compression and ZIP creation run in your browser.
Why can a PNG result be larger?
PNG is lossless and is not controlled by the quality slider. WebP is often smaller for web use.
Can I compress several images?
Yes. Select up to five images and the results are returned in one ZIP archive.
