We use the industry-standard Adam7 interlacing algorithm to ensure compatibility with all modern web browsers and image viewers.
Lossless Toggle
Metadata-only modification means you can enable or disable interlacing without re-encoding the actual pixel data, preserving 100% quality.

Frequently Asked Questions
What is an interlaced PNG?
An interlaced PNG uses the Adam7 algorithm to store pixel data in 7 passes. This allows browsers to render a low-resolution version of the image before all data is downloaded, which is great for large images on slow connections.
Does interlacing increase file size?
Yes, interlacing typically increases the file size by 5-10% because the data is organized in a way that is slightly less efficient for compression. However, the improved perceived loading speed often outweighs this cost.
Is my privacy protected?
100%. All image and metadata processing happens locally in your browser. Your images are never sent to our servers, ensuring your data remains private.
