About This Online Image Compressor

This free image compressor helps you compress JPG, PNG and WebP images directly in your browser — no upload to a server required. Use it to compress a single photo or to compress image files in bulk before adding them to a website, blog post or online store.

Smaller, compressed images load faster and reduce bandwidth usage, which helps page speed, SEO and the overall user experience of any website.

How to Compress an Image Online

1. Choose your images

Select one or more JPG, PNG or WebP images from your device, or drag and drop them into the upload area. You can compress a single image or several images at once.

Use the quality slider to balance image quality against file size, and pick an output format — keep the original format, or convert to JPEG, PNG or WebP. PNG and WebP output keep transparency intact.

4. Download your compressed images

Compare the original and compressed sizes for each image, then download images individually or all together as a single ZIP file.

Frequently Asked Questions

Is this image compressor free?

Yes. This online image compressor is completely free to use, with no sign-up and no limit on how many times you can compress an image.

Which image formats are supported?

You can compress JPG, JPEG, PNG and WebP images, and choose to export the result as JPEG, PNG or WebP.

Are my images uploaded to a server?

No. All compression happens locally in your browser using the HTML5 Canvas API. Your images are never uploaded or sent to a server.

Does compression reduce image quality?

Compressing to JPEG or WebP can reduce image quality depending on the quality level you choose. PNG output is lossless, so quality is preserved but file size savings are usually smaller.

Does this tool keep PNG transparency?

Yes. When you export as PNG or WebP, transparent areas are preserved. If you export a transparent PNG as JPEG, transparency is filled with white since JPEG does not support transparency.

Can I compress multiple images at once?
