Compress JPG

How It Works

Shrink JPG/JPEG file size with an adjustable quality slider. Everything runs the moment you upload an image — there's no queue, no account, and no watermark on your download.

How to Use Compress JPG

1. Upload your image (drag & drop, tap to browse, or paste from clipboard).
2. Adjust the settings if needed.
3. Click the process button.
4. Compare before and after, then download your result.

Supported Formats

JPG, PNG and WebP are supported. Files up to 30MB are accepted.

Why Use Compress JPG

Compress JPG gets a common image job done in seconds without installing desktop software, creating an account, or waiting on a slow upload queue. Your image is processed directly in your browser. It never leaves your device.

Tips

• For the smallest file size, start from the highest-quality original you have.
• If you need an exact pixel size for a form or platform, check the presets on our Image Resizer.
• Chain tools together — for example, resize first, then compress, for the smallest possible result.

FAQ

Is Compress JPG really free?

Yes. Compress JPG is completely free to use, with no signup, watermark or hidden limits on how many times you can use it.

Is my image uploaded to a server?

No. This tool processes your image entirely inside your browser using the Canvas API. Your file never leaves your device.

Will compressing reduce quality?

Some quality loss is a normal trade-off of reducing file size. Use the quality or color-palette slider to find the balance that looks right for your use case.

Does this work on mobile?

Yes — every PixelFree tool is built mobile-first and works on iPhone, Android, tablets and desktop browsers.
