Compression tips for a 500 KB cap

At half a megabyte you will rely more on lossy compression or smaller dimensions. Start with WebP for photographs; fall back to JPEG if a destination only accepts older formats.

Workflow

Upload the image, choose WebP or JPEG, then lower quality until the compressed output clears your goal. If gradients band, nudge quality up slightly or resize the image width first.

Frequently asked questions

Is this image compressor free?
Yes, completely free. No account, no limits, no watermarks.
Are my images uploaded to a server?
No. Everything runs locally in your browser. Your files never leave your device.
Will compression reduce the quality?
Slightly, depending on your quality setting. At 80% quality the difference is usually not visible to the naked eye.
Which format should I use?
WebP gives the best size/quality ratio for most images. Use JPEG for photos and PNG when you need transparency.

Yes. Smaller images improve page load speed and Core Web Vitals, both of which influence Google rankings.
