Image Compressor – Reduce Image Size Without Upload
Shrink photos for websites, WhatsApp and email. Everything happens in your browser.
Leave blank to keep size
How to use the Image Compressor
- Choose a JPG, PNG or WebP image.
- Pick an output format – WebP is usually smallest.
- Set quality (60–80% is a good balance) and an optional max width.
- Press Compress and download the result.
How image compression works
Photos from modern phones are often 3–8 MB. Most of that detail isn't visible on a screen. Lowering JPEG/WebP quality slightly and resizing to a sensible width (for example 1600 px) can cut file size by 70–90% with little visible difference.
Which format to choose?
- JPG – best compatibility for photos.
- WebP – 25–35% smaller than JPG at similar quality; great for websites.
- PNG – lossless; use for screenshots and logos with text (quality slider has no effect).
Why compress?
- Faster websites and better Google Core Web Vitals.
- Meet upload limits on forms and portals.
- Save phone storage and mobile data.
Your images are processed locally with the HTML5 Canvas – nothing is uploaded.
