File size and picture size are different things, and confusing them is why images end up either too heavy or needlessly tiny. A 4,000 pixel photo can weigh 6 MB or 600 KB depending on how hard it is compressed; the pixels are the same, the bytes are not. This tool works on the bytes. You give it a target, 200 KB by default here, and it searches for the best quality that lands under it, keeping your pixel dimensions unless the target is too small to reach that way.
Typical reasons to do this: photos for an email that would otherwise bounce, product pictures for a shop page that loads slowly, a screenshot for a bug report, a scan for an online application, or a WordPress media library that is eating hosting space. In each case the picture looks the same at normal viewing size while the file drops to a fraction of its weight.
Below a certain size, which depends on how much detail the image holds, JPG compression starts to show as soft edges and faint blocks around text. When that happens, raise the target a little; the difference between 100 and 150 KB is often the difference between visible and invisible. JPG, PNG and WebP are all accepted, and nothing is uploaded, so bank statements and ID scans stay on your machine.

Frequently asked questions
- How much smaller can my image get?
- Often dramatically — a multi-megabyte phone photo can drop to a few hundred KB with little visible change. You set the target and the tool hits it.
- Does reducing file size lower resolution?
- Not usually — it lowers quality/compression first and keeps your dimensions. It only downscales if the target is too small to reach otherwise.
- Why is my screenshot bigger than a photo?
- Screenshots are usually saved as PNG, which stores every pixel exactly, so a full-screen capture can weigh several megabytes. Set a target here and it comes down; if small text looks soft afterwards, choose a slightly larger target.
- Will the smaller file still print well?
- Print size depends on pixel dimensions, not kilobytes, so as long as the tool did not need to downscale, the print size is unchanged. For prints, choose a generous target so compression artifacts do not show on paper.

- How to take a passport photo at home that gets accepted The rules that get home-made passport photos rejected are about the photo you take, not the software. Lighting, distance, background, expression and the exact sizes for the US, UK, EU, India and Canada, plus how to print several copies for the price of one.
- HEIC: why iPhone photos will not open on Windows, and every way to fix it Since 2017 iPhones save photos as HEIC, a format half the size of JPG that Windows, many websites and most printers cannot read. What HEIC is, what you lose by converting, the iPhone settings that avoid the problem, and how to convert without uploading.
- What your photos reveal: EXIF, GPS location, and how to strip it before sharing Every phone photo carries a hidden record: where it was taken, when, on which device, sometimes a thumbnail of the uncropped original. Which apps strip it, which do not, how to check a photo, and how to share a clean copy.
