## How to compress a JPG to 50 KB

1. **Add your JPG.** Drop one or more JPG files onto the compressor above, paste them, or click to browse.
2. **50 KB is preset.** The target is already set to 50 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

- At 50 KB a photo keeps enough detail for a face, a signature or a logo, but large photos are scaled down to fit.
- At 50 KB, a detailed JPG photo comes out around 680 × 450 px at good quality; simpler images can stay larger.
- 50 KB here means 50,000 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.

## What fits in 50 KB

| Photo (3:2) | ≈ 920 × 610 px | Acceptable, some artefacts |
| Square photo or avatar | ≈ 550 × 550 px | Good |
