## How to compress a JPG to 500 KB

1. **Add your JPG.** Drop one or more JPG files onto the compressor above, paste them, or click to browse.
2. **500 KB is preset.** The target is already set to 500 KB, and each file is compressed to land at or just under it. You can switch to another size or a percentage to reduce by.
3. **Compress.** Click Compress. The JPG is processed in your browser; nothing is uploaded.
4. **Check and download.** Check the new size, then download each file or all of them as a ZIP.

## Good to know

- Most photos keep high detail at 500 KB; very large camera images are still scaled down somewhat.
- At 500 KB, a detailed JPG photo comes out around 2,150 × 1,430 px (3 MP) at good quality; simpler images can stay larger.
- 500 KB here means 500,000 bytes, so the result also fits forms that count 1 KB as 1,024 bytes.
- JPG compression runs entirely in your browser with WebAssembly, so nothing is uploaded and your files never leave your device.
