Compress images (JPG, PNG, or GIF) to reduce the file size by up to 70 to 80% using lossy compression methods.

How to compress an image?

  • Click “Choose Images” button to upload your JPEG, PNG, or GIF files (you can add up to 20 images)
  • Click the "Compress Now" button to start compressing
  • Once the status change to "Done" click the blue "Download" button to save the compressed images to your computer

Best Image Compressor

Our image compressor does not sacrifice quality for anything. We generate the best quality compressed images without any apparent quality loss. Our intelligent image compressor analyzes each image to find the best compression strategy. All you have to do is upload and click compress!

Easy to Use

Unlike our JPEG Compressor and PNG compressor, this tool does not have advanced options. We wanted to make it simpler for folks to compress images. However, in the background, we are applying the following advanced compression strategies:

  • Lossy Compression - to reduce file size, we apply lossy compression to your images. This means some image details will be lost. However, we balance between compression and quality. In most cases, you won't notice a difference between the original and compressed version.
  • Progressive compression - For JPEG images, we apply progressive compression. It is more effective for 10Kb or lager JPEG images. Plus, has the added benefit of progressive rendering on a browser (without waiting for the whole image to download)
  • Reduce Chroma sampling - Implements less resolution for chroma information than for luma information because the human eye is less sensitive to color differences than for luminance. Applies to JPEG images.[1]

Free & Secure

Our image compressor is 100% free. It works on any web browser. There are no registrations or software to install.
We delete all images within 6 hours of compressing them. Plus, all uploads are done over a secure HTTPs connection.


How does it work?

By default, we compress JPEG and PNG images using a combination of lossy & progressive compression while reducing chroma sampling to 4:2:0. Our goal is to reduce JPEG file size at the highest possible image quality. This tool also follows the image compression guidelines set by Google.

For PNG and GIF images, we apply lossy compression while preserving transparency. Further, for PNG images, we strip 32-bit truecolor PNGs to 8-bit indexed color PNGs.

For all images, we strip metadata such as EXIF to reduce image size further.

Why should I compress images?

A web page with optimized images load faster, and your visitors will thank you for it! It can also lower your bandwidth cost. You can also share, upload, or e-mail your images faster when they are optimized.

Is there a max file size limit?

We can compress large images up to 1GB!
