API: `POST /api/v1/jobs` with `"operation": "compress", "target_size": "500kb"` (paid plans).

## How to compress a PNG to 500 KB

1. **Add your PNG.** Drop one or more PNG 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 PNG 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.
- PNG keeps logos and screenshots crisp at 500 KB, but photos have to be scaled down a long way. For photos, converting PNG to JPG reaches 500 KB at a much higher resolution.
- 500 KB here means 500,000 bytes, so the result also fits forms that count 1 KB as 1,024 bytes.
- PNG compression runs entirely in your browser with WebAssembly, so nothing is uploaded and your files never leave your device.

## What fits in 500 KB

PNG is lossless at heart, so what fits in 500 KB depends heavily on the content.

| Content | Roughly fits | Notes |
| --- | --- | --- |
| Logo or flat graphic | ≈ 2,580 × 2,580 px (7 MP) | Few colours compress very well |
| Screenshot | ≈ 2,000 × 1,250 px (3 MP) | After palette reduction |
| Photo | ≈ 1,100 × 730 px | Convert to JPG for far more |

_Rough guide for square, 16:10 and 3:2 images. Real results depend on detail and colour count._

## What 500 KB is typically for

- Full-width hero and banner images
- Photo uploads on forms that allow up to 500 KB
- Sharing photos in chats without sending the full original

Limits vary by site and change over time; check the exact number where you're uploading.

## How PNG gets smaller

Reduces the colour palette (lossy levels) and re-compresses at maximum zlib effort.
