When to compress images
Make Images Easier to Share
Compress large photos before sending them by email, messaging apps, or other online services.
Meet Upload Size Limits
Reduce file size when a website, form, or online platform limits how large an uploaded image can be.
Save Storage Space
Create smaller PNG, JPEG and WebP files to use less storage space without changing their pixel dimensions.
Compress Multiple Images

Image compression details
- The compressor accepts static PNG, JPEG and WebP images and keeps each image in its original format.
- Compression does not resize your images. The output keeps the same width and height as the original.
- JPEG and WebP use adjustable encoding quality, while PNG uses color reduction to produce smaller files at lower quality settings.
- If recompressing an image would create a file that is the same size or larger, the original file is kept instead.
- Compress up to 20 images in one batch, with each uploaded file limited to 10MB.
- Each result shows the original file size, compressed file size, and percentage change.
- Image decoding, compression, previewing, and export happen locally in your browser without uploading the files to a server.
Frequently asked questions
How do I compress an image online?
Upload one or more PNG, JPEG or WebP images, adjust the quality if needed, and click Compress Images. You can then compare file sizes, preview the results, and download the compressed files.
Which image formats can I compress?
The tool supports static PNG, JPEG and WebP images. Animated PNG and animated WebP files are not supported.
Does image compression reduce image quality?
It can. JPEG and WebP use lossy compression, while PNG may reduce the number of colors at lower quality settings. Higher quality preserves more visual detail but usually produces a larger file.
Will the image format or dimensions change?
No. The compressed image keeps the same file format, width, and height as the original.
What happens if compression makes the file larger?
The tool keeps the original file whenever the compressed version would be the same size or larger, so compression will not replace it with a bigger file.
Are my images uploaded to a server?
No. Your images are processed locally in your browser. You can compress up to 20 images at once, with a maximum file size of 10MB per image.
