Image Compressor

Compress images by adjusting quality to reduce file size

About Image Compressor

The Image Compressor is a free online image and media tool that lets you compress images by adjusting quality to reduce file size. It runs entirely in your browser, which means your data is never uploaded to a server — everything stays private on your device. There is no account required, no file-size limit that matters for everyday use, and no ads or paywalls in the way.

How to use it

Upload a file by clicking the upload area or dragging and dropping. The tool processes it instantly in your browser. The output is ready to copy to your clipboard with a single click, or you can download it as a file.

When it comes in handy

This tool is useful for generating visual elements for marketing materials, optimizing images and assets for the web, and preparing visual assets for websites and apps. Anyone who works with text or data regularly — writers, developers, marketers, students, and data analysts — will find it saves time compared to doing the same task manually or installing dedicated software.

Why use this over alternatives

Desktop applications and IDE plugins can do similar things, but they require installation, configuration, and often a learning curve. This tool loads instantly in any browser, works on any device including phones and tablets, and handles the job in one paste-and-copy step. Because all processing happens locally with JavaScript, it is fast even on large inputs and completely private — ideal for sensitive or proprietary content.

Frequently asked questions

How does the compression work?

The tool re-encodes your image at a lower JPEG or WebP quality setting using the browser's built-in Canvas API. You control the quality slider from 1% to 100%, and the file size updates in real time.

Will compression make my image look bad?

At 70–85% quality, most images are visually indistinguishable from the original while being 40–60% smaller. Below 50% you may notice artifacts, especially on text and sharp edges.

Can I compress PNG files?

Yes. The tool converts PNGs to JPEG or WebP for lossy compression. If you need lossless PNG output, the file size reduction will be minimal since PNG is already losslessly compressed.
