About the JPG Compressor

We developed this JPG Compressor to solve the universal problem of slow-loading websites caused by large images. JPEG (or JPG) is the standard format for photography on the web, but cameras and stock photo sites often export these files at unnecessarily high quality levels. This results in bloated files that eat up bandwidth and slow down your pages.

Our tool uses smart lossy compression algorithms to reduce the file size of your images by up to 80% without perceptible loss of visual quality. The secret lies in selectively removing high-frequency data that the human eye struggles to see anyway. This means you get a much lighter file that looks virtually identical to the original.

Privacy and speed are built into the core of this tool. Unlike other services that require you to upload your photos to a cloud server, our compressor runs entirely within your web browser. Your images are processed locally on your computer, ensuring that your personal photos and data never leave your control.

How to Use the Tool

  • Upload your JPG file (or PNG/WEBP) by clicking "Browse" or dragging and dropping it into the box.
  • The tool will automatically compress the image.
  • Use the interactive slider on the preview image to compare the "Original" vs "Compressed" versions in real-time.
  • Adjust the "Compression Level" slider. A value of 80% is usually the sweet spot, but you can go lower for smaller files or higher for maximum quality.
  • Check the "Savings" badge to see how many kilobytes or megabytes you have saved.
  • Click "Download Compressed JPG" to save the optimized file to your computer.

Frequently Asked Questions

What is the difference between JPG and JPEG?

There is no difference! JPG and JPEG are the exact same file format. The three-letter extension (.jpg) exists because older Windows systems only supported three-letter file extensions. Our tool handles both extensions interchangeably.

Why does compression reduce file size so much?

JPG compression works by simplifying the color information in the image. The human eye is very sensitive to brightness (light and dark) but less sensitive to exact color differences. By averaging out similar colors in small blocks of pixels, the file size drops dramatically while the image looks largely the same.

What is the best quality setting for websites?

For general web use, a quality setting between 75% and 80% is ideal. This usually provides a great balance where artifacts are invisible to the naked eye, but the file size is significantly reduced. For hero images or photography portfolios, you might prefer 85-90%.

Can I compress PNGs with this tool?

Yes, you can upload PNG files. However, the output will be converted to JPG format. Since JPG does not support transparency, any transparent backgrounds in your PNG will turn white. If you need to keep transparency, use our PNG Compressor instead.

Is it safe? Do you store my photos?

It is 100% safe. This tool is a client-side application, meaning the code runs in your browser. Your images are never sent to our servers, so your privacy is guaranteed.
