How to Compress PNG Images Online
PNG files are notoriously large because they use lossless compression. Our PNG Compressor applies advanced algorithms to reduce their size:
- Click Select Image to upload your PNG file.
- The tool will automatically attempt to compress the PNG data.
- Compare the original and compressed file sizes.
- Click Download Compressed Image.
Why Are PNG Files So Big?
Unlike JPGs, standard PNG files are "lossless." This means they preserve every single pixel perfectly without throwing any data away. While this is fantastic for high-quality logos or images with text, it results in massive file sizes that can slow down your website.
Our tool helps compress the underlying data structure of the PNG, and can optionally convert it to a modern WebP format if you need extreme size reduction while keeping transparency.
Frequently Asked Questions
Will I lose my transparent background?
No. Our PNG compressor fully supports the alpha channel (transparency). Your transparent backgrounds will remain perfectly intact.
Can I convert my PNG to WebP?
Yes. If you select "WebP" in the output format dropdown, the tool will convert your PNG to a WebP file, which often results in a file 50% smaller while still supporting transparency!
Is this tool free?
Yes, all image compression tools on ImageShrink.in are completely free to use with no limits.
