Compress images to 100 KB online

This free image compressor shrinks JPG, PNG, and WebP images down to a target file size — 100 KB by default, or any size you choose. It runs entirely in your browser, so your photos are never uploaded to a server, keeping them completely private. Choose an image, set your target size, and download the compressed result in seconds.

How it works

The tool redraws your image on a canvas and intelligently searches for the highest JPEG quality that still fits under your target size, so you get the smallest file with the best possible appearance. You can also set a maximum width to shrink very large photos — often the quickest way to hit a small target while keeping the image sharp.

Why compress images?

Smaller images load faster, use less storage, and are often required by forms and upload limits — for example, job portals and government sites that cap photo uploads at 100 KB or 200 KB. Compressing also speeds up websites and emails. The output is a standard JPEG that works everywhere.

Frequently asked questions

Are my images uploaded anywhere?

No. All processing happens locally in your browser using your device’s own resources. Nothing is sent to us or any server.

Why is my compressed file a JPG?

JPEG gives the best size-to-quality ratio for photos, which is how the tool reliably hits small targets. If you need a PNG, compress first, then convert separately.
