Re-encode your PNG images with the browser's compressor to reduce their size without losing quality, directly on your device.
PNG is a lossless format: compression is limited to re-encoding the data more efficiently, without discarding any image information. The reduction is usually more modest than with JPG or WEBP.
Use cases
- Optimizing screenshots before sharing them.
- Reducing the size of unoptimized PNGs generated by other tools.
- Preparing website images without losing sharpness.
How it works

Download the result
Compare the size before and after compression.
Frequently asked questions
- Why is the reduction smaller than with JPG?
- Because PNG is lossless by design: it doesn't discard image detail, it only compresses the data more efficiently. If you need the maximum possible reduction and can do without transparency, consider converting to JPG or WEBP instead.
