Shrink a PNG to 50 KB or less for ID photos, signatures and forms that cap uploads at 50 KB.

API: `POST /api/v1/jobs` with `"operation": "compress", "target_size": "50kb"` (paid plans).

## How to compress a PNG to 50 KB

1. **Add your PNG.** Drop one or more PNG 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 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

- At 50 KB a photo keeps enough detail for a face, a signature or a logo, but large photos are scaled down to fit.
- PNG keeps logos and screenshots crisp at 50 KB, but photos have to be scaled down a long way. For photos, converting PNG to JPG reaches 50 KB at a much higher resolution.
- 50 KB here means 50,000 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 50 KB

PNG is lossless at heart, so what fits in 50 KB depends heavily on the content.

| Content | Roughly fits | Notes |
| --- | --- | --- |
| Logo or flat graphic | ≈ 820 × 820 px | Few colours compress very well |
| Screenshot | ≈ 630 × 400 px | After palette reduction |
| Photo | ≈ 350 × 230 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 50 KB is typically for

- Passport and ID photos on online applications
- Profile pictures and avatars
- Logos in email signatures

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.

### How do I compress a PNG to 50 KB?

Drop the PNG onto the compressor above. The 50 KB target is already set, so just click Compress and download the result.

### Will the file be exactly 50 KB?

It aims to land at or just under 50 KB. 50 KB here means 50,000 bytes, so it also fits sites that count 1 KB as 1,024 bytes.

### How much quality will I lose at 50 KB?

At 50 KB a photo keeps enough detail for a face, a signature or a logo, but large photos are scaled down to fit. PNG keeps logos and screenshots crisp at 50 KB, but photos have to be scaled down a long way. For photos, converting PNG to JPG reaches 50 KB at a much higher resolution.

### My PNG is already smaller than 50 KB. What now?

Then it already fits, and compressing it further would only cost quality. Upload it as it is, or pick a smaller target if you need it smaller still.

### What if my PNG can't get down to 50 KB?

Very large or detailed images are scaled down further to reach 50 KB. If the result is too small, pick a larger target.

### What is 50 KB typically needed for?

Common reasons: passport and ID photos on online applications; profile pictures and avatars; logos in email signatures. Limits vary by site, so check the exact number where you're uploading.

Yes. It's compressed inside your browser and never uploaded.
