How to compress a JPG to 500 KB

  1. Add your JPG. Drop it into the box above or click to browse. The photo opens in your browser and never reaches a server.
  2. The 500 KB target is already set. JPG output is selected too, so the file you download is still a JPG.
  3. Check the preview, then download. You see the real finished size before saving, so there is no trial and error at the upload stage.

Frequently asked questions

How do I compress a JPG to 500 KB?

Drop your JPG in — the 500 KB target is set — and the tool finds the best JPEG quality that stays under 500 KB. The output stays a JPG.

Does it reduce quality?

Only as much as needed to hit the target. It keeps the highest quality that fits and shows a preview before you download.

Is my JPG uploaded?

No — compression runs in your browser and the file never leaves your device.

Getting a JPG under 500 KB

The 500 KB JPG limit is common on high-quality web JPGs and portfolio images capped at half a megabyte. Set it above and download a JPG that fits.

What to expect

At 500 KB, JPG compression is essentially invisible for a single photo.

Tip

For a site you control, WebP fits even more quality into the same 500 KB. You can also use the image compressor for PNG and WebP.

What happens behind the scenes

The tool runs a rapid binary search over quality levels, measuring the true output size at each step until it lands on the highest quality that still fits under 500 KB. You get a preview before downloading, so there are no surprises. If the image is very large for a tight target, it also gently reduces the pixel dimensions, because a slightly smaller but clean image always looks better than a full-size one riddled with compression artefacts.

Why an exact 500 KB target matters

Upload forms reject anything over their stated limit, so "roughly smaller" is not good enough — you need to land under 500 KB on the first attempt. Aiming for the exact size gives you the best-looking image that still passes, instead of over-compressing out of caution and ending up with something needlessly blurry.

Need a different JPG size?

Every limit below uses the same tool with a different target, so you can go straight to the one your form or inbox actually asks for. If you only need a smaller file size in general and no exact number, pick the next limit up from where you are now and keep more quality.
