How it works
Upload your images and adjust the quality slider to balance file size against visual quality. You'll see the resulting size for each file, so you can dial in the exact trade-off you want before downloading. PNG files can be optimized losslessly, keeping every pixel intact.
When to compress images
Compressing before you publish speeds up page loads and improves Core Web Vitals, which helps SEO. It also makes photos small enough for email attachment limits and saves storage space — usually with no noticeable drop in quality.
Frequently Asked Questions
How do I make an image smaller?
Lower the quality slider and watch each file's resulting size update. Lower quality means a smaller file; for most photos you can cut size substantially with no visible difference.
Will compressing reduce image quality?
JPG and WebP use lossy compression, so there's a small trade-off at lower settings, usually invisible for photos. PNG compression is lossless — the image stays pixel-for-pixel identical.
Which format gives the smallest file?
For photos, JPG and WebP are smallest. WebP is typically 25–35% smaller than JPG at similar quality.
Are my images uploaded anywhere?
No. Compression runs entirely in your browser — your images never leave your device.
