What is Compress Image?
Compress Image reduces the file size of your photos directly in your browser — no upload to any server. Upload a JPG, PNG, or WebP image, adjust the quality slider to find the right balance between file size and visual quality, and download the compressed result.
Note: the output is always saved as JPEG, which works well for photos but will convert PNG files to JPG format. Ideal for speeding up web pages, meeting upload size limits, or reducing storage usage. Because all processing runs on your device, your images stay completely private.
Common Use Cases
- Reducing photo file sizes for faster web page loading
- Meeting upload size limits on forms and platforms
- Optimizing images for social media posts
- Shrinking photos before attaching to email
- Reducing storage usage on disk or cloud storage
How to Use Compress Image
- Upload a JPG, PNG, or WebP image from your device.
- Move the quality slider to control the compression level.
- Preview the result, then download the compressed image.

FAQ
Are my images uploaded to a server?
No. Compression runs entirely in your browser using the Canvas API. Your images never leave your device.
Which image formats can I upload?
You can upload JPG, PNG, and WebP images. The compressed output is always saved as JPEG, so PNG files will be converted to JPG format.
Will the compressed image lose quality?
Yes. The tool uses lossy JPEG compression — some fine detail is traded for a smaller file. The quality slider lets you control the trade-off. Higher quality means a larger file but a sharper image.
How much will it reduce the file size?
It depends on the original image and quality setting. Typical results range from 30% to 80% reduction. Photos compress more than images with flat colors.
Can I compress multiple images at once?
Currently the tool processes one image at a time. Upload, compress, download, then repeat for additional files.
Why is the output always JPEG and not PNG?
JPEG compression is lossy but achieves much smaller file sizes for photographic content. PNG uses lossless compression, which keeps file sizes larger. If you need to preserve transparency (alpha channel), the output JPEG won't support it — use the Remove Background tool first if you need a transparent PNG instead.
