The problem
Page speed matters. Google uses Core Web Vitals as a ranking signal, and images are almost always the heaviest assets on a page. An unoptimized hero image can add 2-3 seconds to your load time, hurt your search ranking, and frustrate mobile users on slow connections.
You know you should optimize your images. But for each image, that means: pick the right format, choose a quality level, strip metadata, maybe resize, then export. Multiply that by 20 images for a blog post or product page, and you've lost an hour on busywork.
How it works
- Drop your image onto the optimizer. That's it.
- The tool automatically:
- Converts to WebP (the most efficient web format)
- Strips EXIF metadata (camera info, GPS coordinates, timestamps)
- Applies smart compression at quality 80 (the sweet spot for web images)
- See the result — before and after file sizes with the percentage you saved.
- Download — one click.
No sliders, no format pickers, no decisions. One input, one output.
For images that need more control — specific quality levels, different output formats, manual resizing — click "Advanced options" to open the full Image Compressor with your image already loaded.
Why WebP
WebP produces files 25-35% smaller than JPEG and significantly smaller than PNG, with no visible quality difference at equivalent settings. It supports both lossy and lossless compression, plus transparency.
Every major browser supports WebP: Chrome, Firefox, Safari, Edge, and all mobile browsers. The only holdout was IE11, which Microsoft discontinued in 2022.
If you're building for the modern web, there's no reason to serve JPEG or PNG as your primary image format. WebP does everything they do, smaller.
What metadata gets stripped
Digital photos carry hidden metadata (EXIF data) that can include:
- Camera settings: aperture, shutter speed, ISO, focal length
- Device info: phone model, software version
- GPS coordinates: where the photo was taken
- Timestamps: when the photo was taken
This metadata adds file weight (sometimes 50-100KB per image) and can be a privacy concern — especially GPS coordinates in photos uploaded to public websites. The optimizer removes all of it.
How much will you save?
Typical results:
- Phone photos (3-5MB JPEG): 70-85% reduction (down to 200-500KB)
- Screenshots (PNG): 80-90% reduction (PNG to WebP is dramatic)
- Already-compressed JPEGs: 15-30% reduction (still worth doing)
- Small graphics and icons: minimal savings — these are already tiny
The optimizer shows exact before/after numbers so you can see the impact on every image.
