Why use an online image compression tool?

An online image compressor can significantly reduce file size without changing the image format, helping pages load faster. It is ideal for webmasters, designers, and content creators who publish many images.

This tool runs entirely in your browser, so your images are not uploaded to a server. It saves bandwidth and protects privacy while allowing you to adjust compression quality to balance visual effect and file size.

You can batch add up to 30 images, each up to 20MB. The tool shows original size, compressed size, and compression ratio for every image so you can clearly see the before-and-after difference.

After compression, you can download images one by one or pack all compressed images into a single ZIP file. This is convenient for downloading website assets, project images, or event posters in bulk.

FAQ about online image compression

Is this image compression tool free to use?

Yes, it is completely free. No registration or login is required and there is no usage limit.

Will the image format change after compression?

No. A JPG stays JPG, a PNG stays PNG, and a WebP stays WebP after compression.

Are my images uploaded to the server?

No. All compression is done locally in your browser, so your images are not uploaded, which is safer and more private.

How many images can I compress at one time?

You can add up to 30 images in a single batch. Extra files over the limit will be ignored.

Is there a size limit for each image?

Yes. Each image must be 20MB or smaller. Larger files will be skipped with a notice.

What compression quality should I choose?

In most cases, 60%–80% quality is a good balance between file size and visual quality.

Will the compressed images look very blurry?

There may be a slight loss of sharpness with lossy compression, but it is usually acceptable for normal use. You can test different quality levels.

Can I download only some of the compressed images?

Yes. Each row has its own download button, so you can download only the images you need or download all as a ZIP.

How do I open the downloaded ZIP file?

The ZIP file uses the standard format and can be opened by Windows, macOS, and most archive tools.

Is this tool convenient to use on mobile devices?

Yes. You can scan the QR code on the right to open it on your phone, but for many large images, using a desktop browser is more stable.
