Explanation

What this tool does

Compress and resize images locally in your browser. Choose max width and quality, then download the result — nothing is uploaded.

Example

A 4000px photo resized to 1600px max width at 80% JPEG quality is usually much smaller while staying sharp enough for the web.

When to use it

Use it when you need a fast browser-based utility without uploading your text, files, or other input.

Common mistakes

  • Setting quality so low that important detail disappears.
  • Resizing below the size needed for print or retina displays.
  • Expecting lossless results from a lossy JPEG quality setting.

Frequently asked questions

Is my image uploaded?

No. Compression and resizing run in your browser with the Canvas API. The original file never leaves your device.

Which formats work best?

JPEG is usually best for photos. PNG keeps sharper edges for screenshots and graphics, but may stay larger.

Will quality drop?

Yes, lower quality settings reduce file size by discarding some detail. Start around 70-85% for web photos and adjust.

Is the Image Compressor free to use?

Yes. All LearnLinx calculators are completely free with no signup required. Signing in is optional and only adds a 60-day history of your calculations.
