A lighter image. A clearer upload.

Make your image
fit the limit.

Set a file size budget and maximum dimensions. We try the compression, then show you the actual bytes and preview. Everything runs in this browser tab.

JPEG cannot store transparency. Transparent areas are filled with white.

Aspect ratio stays intact; images are never enlarged. Dimensions only change to fit the maximums you enter. If the target cannot be met, try smaller maximums yourself.

Animated PNG/WebP, GIF, SVG and HEIC are not supported. Canvas export creates a new image; review colour, orientation and small text in the preview.

Dimensions first

Pixels and KB do different jobs.

A 1280 × 800 image can weigh many different amounts. Maximum dimensions reduce the pixels; a file size budget controls how much encoded data an upload permits.

Honest results

A target is a budget, not a promise.

JPEG and WebP use up to nine quality trials at the chosen dimensions. PNG is re-encoded once, without a lossy quality setting. The tool always reports the actual saved byte count.

Your file stays in this tab.

The browser reads and transforms the image locally. No image processing server is involved. Large files are limited before decoding to keep this small tool manageable.
