Compress image to 500 KB
At 500 KB you can keep a photo looking essentially perfect on screen — this is the generous tier used by real-estate listings, classifieds sites, and most CMS platforms. Modern phone photos are typically 3–8 MB, so they still need a 90% reduction to fit.

A high-quality tier for larger photos
500 KB is the comfortable end of the compression scale. There's enough room to keep a full-width, detailed photo looking crisp, which is why it's favoured by platforms that care about how images look rather than squeezing every last kilobyte.
- Real-estate and property listing photos.
- Classifieds and marketplace galleries.
- Blog hero images and portfolio shots.
- CMS uploads where quality matters more than raw speed.
How much quality do you actually lose?
Usually none that you can see. 500 KB in WebP holds a sharp 1920 px photo with room to spare, so on any screen the compressed version is essentially indistinguishable from the original. The savings come almost entirely from throwing away data your eyes can't perceive — not from visible degradation.
The only time you'd notice is with heavy cropping afterwards or a large print, where the missing detail finally becomes visible. For web and on-screen use, 500 KB is effectively lossless in practice.

Frequently asked questions
How much quality do I lose at 500 KB?
Usually none that you can see on screen. 500 KB in WebP comfortably holds a sharp 1920px photo. Only large prints or heavy cropping would reveal the difference.
Is my image uploaded to a server?
No. Compression happens entirely in your browser using the Canvas API — your image never leaves your device, which is also why it's instant.
What if my image can't reach 500 KB?
The tool first lowers the compression quality, and if that's not enough it gradually reduces the dimensions until the file fits under 500 KB. Extremely detailed images may lose visible quality at very small targets — the preview shows you exactly what you'll get.
