Frequently Asked Questions
Is PNG compression lossless?
PNG compression can be both lossless and lossy. Our tool uses intelligent optimization techniques to reduce file size while maintaining visual quality. You can adjust the quality slider to find the perfect balance for your needs.
Will transparency be preserved?
Yes! Our PNG compressor fully preserves the alpha channel (transparency) in your images. This is one of the key advantages of using PNG format for web graphics and logos.
What is the maximum file size?
There are no strict file size limits since all processing happens in your browser. However, very large files may take longer to process depending on your device's capabilities.
Are my files secure?
Absolutely! Your files never leave your device. All compression happens directly in your web browser using JavaScript and WebAssembly. We cannot see, access, or store your files.
