# Compress PNG to 500 KB

Reduce PNG screenshots, logos, and graphics to under 500 KB. Browser-based and completely private — no uploads, no signup.

> Everything runs in your browser. Your files are never uploaded.

## About this tool

PNG is a lossless format, which means a typical screenshot or UI mockup can easily weigh 2–6 MB. For bug reports, design hand-offs, and documentation sites, you want something closer to 500 KB — and that usually means converting to a high-quality JPEG while keeping the filename and resolution usable.

This tool takes your PNG, re-encodes it as a high-quality JPEG behind the scenes, and bisects the quality setting until the result lands under 500 KB. You get a visually near-identical image that is a fraction of the size.

Transparency is not preserved — by definition, JPEG cannot store an alpha channel. If you need transparency and a small file size, use a WebP converter instead. For everything else (screenshots, photos, flat graphics), compressing PNG to a smaller JPEG is the right trade-off.

## Frequently asked questions

### How do you compress a PNG to 500 KB?

PNG is lossless, so the only way to shrink it meaningfully is to re-encode as JPEG. We do that with a quality setting chosen by binary search to land just under 500 KB, and save the result as .jpg.

### Why didn't my image reach exactly 500 KB?

We target 'under 500 KB', not an exact number. A 420 KB output still clears any 500 KB gate. If your PNG has huge dimensions or very detailed content we downscale it once and retry at minimum quality.

### Will I lose transparency?

Yes. The output is a JPEG, and JPEG has no alpha channel. Transparent pixels become white. If you need transparency, try compressing to WebP instead.

### Can I keep the .png extension?

The file is saved with a .jpg extension so your operating system and viewers open it correctly. The dimensions stay the same unless downscaling was required.

### Is the compression done on my device?

Yes. Everything runs inside the browser tab using WebAssembly. Your screenshots and design files never leave your machine.
