How it works

Three simple steps to target the image size you need.

Choose image

Select a JPG, PNG, or WebP image from your device. Your file stays local and is never uploaded anywhere.

Choose target size

Select a preset target or enter your own KB or MB value. The interface will confirm your chosen size.

Download

When compression finishes, your optimized image is ready to download — processed entirely on your device.

Built for real-world use

Compixu is designed for the workflows that need precise file sizes.

Government & application portals

Many official portals enforce strict file size limits for uploaded documents and photos. Compixu helps you fit images within those limits.

Email attachments

Many email services cap attachment sizes. Compress images to stay within limits without sacrificing more quality than necessary.

Profile & marketplace images

E-commerce platforms and social networks often limit image sizes. Fit your photos to their requirements before uploading.

Fast private browser processing

Everything runs locally on your device. No image uploads, no server-side image processing, no registration. Your images are processed instantly and privately.

Frequently asked questions

Everything you need to know about Compixu.

Are my images uploaded?

No. Files are processed entirely in your browser. Nothing is uploaded to any server. Your images never leave your device.

Can I choose a target KB size?

Yes. You can pick one of the preset targets (20 KB, 50 KB, 100 KB, 200 KB, 500 KB, 1 MB) or enter a custom value. The compression engine is designed to hit your target size as closely as possible.

Which formats are supported?

JPG, PNG, and WebP images are supported. Choose JPEG, PNG, or WebP explicitly for the output. If the detected source format matches your choice and the file is already within the target, Compixu can reuse the original file.

Does Compixu work on mobile devices?

Yes. The interface is fully responsive and designed for modern mobile browsers. You can compress images on your phone or tablet with the same privacy protections.
