Is 500KB enough for retina-quality photos?
Usually yes. A 1920×1080 photo at WebP quality 85 typically lands around 200–500KB and looks identical to the source on every display.
Can I push images higher than 500KB if needed?
Use the universal Compress to KB tool with a custom target. Or just use the Compress Image page without a size target.
Are my images uploaded to your server?
No. All images are processed locally in your browser using JavaScript and WebAssembly. Your files never leave your device, and we have no infrastructure that could receive them.
Can I compress multiple images?
Yes. You can drop a batch of images (or an entire folder) and download the compressed results as a single ZIP file with the original folder structure preserved.
Which formats are supported?
JPG, PNG, WebP and AVIF are supported when available in your browser. The Auto mode picks the smallest modern format your browser can encode.
Can I compress images to a specific size?
Yes. Use the
Compress to KB tool to target 100KB, 200KB, 500KB, 1MB or any custom size.
Do I need an account?
No. There is no signup, no login, and no payment. The tool works as soon as the page loads.
