How target-size compression works
The compressor processes your image in the browser. When a smaller target is required, it intelligently adjusts image dimensions and searches for the closest achievable PNG file size.
Processing happens locally in your browser. Your image does not need to be uploaded to our server.
Online PNG Compressor
Compress PNG Images Without Installing Software
Large PNG files can take longer to upload, consume more storage and increase webpage loading times. Our PNG compressor helps reduce PNG file size by processing the image directly in your browser.
Choose a target such as 100KB, 200KB, 500KB, 1MB or enter your own size. The compressor attempts to create a PNG that is as close as practical to your selected target.
Choose your target
Set a target size in KB instead of guessing which compression setting you need.
Process images privately
Your image is processed by your browser, so the original file does not need to be sent to a compression server.
Target size guide
What PNG Target Size Should You Choose?
The best target depends on where you plan to use the image. Smaller targets create smaller files, while larger targets generally allow more image data to remain.
| Target | Good for | General recommendation |
|---|---|---|
| 50 KB | Very small web graphics and simple images | Best when file size is the highest priority |
| 100 KB | Websites, forms and small graphics | A useful balance for many online uploads |
| 200 KB | Larger graphics and screenshots | Useful when 100 KB is too restrictive |
| 500 KB | Detailed images and website assets | Better choice when preserving more detail matters |
| 1 MB | Larger PNG images | Useful when the upload limit allows a larger file |

Different image formats are designed for different purposes. PNG is particularly useful when transparency, sharp graphics or lossless-style image handling is important.
PNG
Excellent for graphics, screenshots, transparency and images requiring crisp edges.
JPG
Commonly used for photographs and images where smaller file sizes are important.
WebP
A modern web format that can provide efficient compression for many websites.
AVIF
A newer image format designed for highly efficient web image compression.
Compression tips
Tips for Getting Better PNG Compression Results
A smaller target is not always better. Choosing a practical target size can help balance file size, image dimensions and visual detail.
Start with a realistic target
If your original image is very large, a 100KB target may require significant dimension reduction. Try 200KB or 500KB when more detail is needed.
Use PNG for the right images
PNG is especially useful for screenshots, interface graphics, illustrations, logos and transparent images.
Compare before downloading
Use the before-and-after comparison to inspect the result before saving the compressed PNG.
Check the final dimensions
Very aggressive compression may require smaller dimensions. Always check the resulting dimensions when image resolution matters.
