Compress Image to a Target Size

What "compress to a size" actually means

Lots of upload forms set a hard file-size limit — a job portal that rejects resumes photos over 200 KB, a passport or visa form capped at 50 KB, a college application that wants your photo under 100 KB. This tool shrinks a JPG or PNG until it fits under the exact KB target you type in, so the form finally accepts it. You're not changing the pixel dimensions on the page — you're lowering the file weight until it slides under the ceiling.

When you'd reach for this

A phone photo today is often 3–8 MB. That's 15–40 times too big for a form asking for 200 KB. Typical moments: government and banking forms, exam and scholarship registrations, applicant tracking systems, HR portals, and email attachment caps. A quick tip — JPG almost always hits a small target better than PNG for photos, because JPG throws away detail your eye barely notices. Keep PNG only when you need a screenshot or a logo with sharp text or a transparent background.

How it works

The tool re-encodes your image at a lower quality setting and, if needed, scales it down a little, then checks the resulting file size. It repeats until the file lands just under your target — giving you the best-looking version that still fits. Everything happens on your device; the picture is never uploaded.

How to use it

1. Choose your JPG or PNG, or drag it onto the page.
2. Type your target size in KB (for example 100 or 200) — match whatever the form demands.
3. Let it compress, then compare the preview and the new file size against the original.
4. Download the compressed image and upload it to your form.

FAQ

Will the photo look blurry?

At 100–200 KB most photos still look fine on screen. The lower you push the target, the softer it gets — so aim for the highest number the form allows, not the smallest.

My PNG won't get small enough — why?

PNG is lossless, so a detailed photo stays heavy. Save or convert it to JPG first, then compress — you'll hit tiny targets like 50 KB far more easily.

What's the difference between KB and pixels?

KB is the file's weight; pixels are its width and height. Forms usually limit KB. This tool targets KB, trimming quality (and dimensions only if it must) to get there.

Is it free and private?

Yes — free and ad-supported, and the image is processed entirely in your browser, never sent to a server.
