Image Compressor
Choose an image, set the quality, and compress it on your device. The file is not uploaded to NEXNARA.
Privacy-friendly Your images are processed locally in your browser and are not uploaded to our server.
Large images may take longer to process.
Lower quality usually means a smaller JPG or WebP file.
Very low quality can make the image look blocky or blurred.
PNG is re-encoded without removing transparency. Size reduction is often small because PNG is lossless.

What is an Image Compressor?
An image compressor reduces the file size of a picture so it is easier to store or send. This tool runs in your browser. You keep the same format: JPG stays JPG, PNG stays PNG, and WebP stays WebP.
How to compress an image
- Drop an image onto the box, or choose a file from your device.
- Check the original size, then set the quality if the file is JPG or WebP.
- Select Compress Image. Work happens on your device.
- Compare the result, then download the compressed file or reset to start over.
Image quality and file size
For JPG and WebP, lower quality usually makes a smaller file and can add visible loss. A setting around 80% is a reasonable starting point. PNG is lossless, so the quality slider does not apply, and the file often stays close to the original size.
Privacy
Compression runs in your browser. The image you choose is not sent to NEXNARA servers.
Supported formats
You can use JPG, JPEG, PNG, and WebP files up to 20 MB. Other formats are not accepted. PNG files with a transparent background keep their transparency.
FAQ
Does compression reduce image quality?
For JPG and WebP, yes — lower quality can make the picture look less sharp. PNG is lossless, so the pixels stay the same, but the file may not get much smaller.
Are my images uploaded?
No. The image stays in your browser for this tool and is not uploaded to NEXNARA.
Which formats are supported?
JPG, JPEG, PNG, and WebP. Files larger than 20 MB are rejected.
Can I compress images on mobile?
Yes. The tool works in modern mobile browsers. Very large photos may take longer or fail if the device runs out of memory.
Why doesn't my PNG become much smaller?
PNG is a lossless format. This tool re-encodes PNG without stripping transparency and without converting it to JPG. If the original file is already well compressed, the size may stay the same or even grow; in that case the original file is kept.
