Frequently asked questions about PNG compression
What is PNG compression?
PNG compression is the process of reducing PNG file sizes without quality loss. Unlike JPEG, PNG uses lossless compression algorithms, preserving transparency and all details.
How much can you compress a PNG file?
PNG files can be compressed by 30-70% of the original size depending on image content. Images with large uniform areas compress better.
Is transparency preserved after compression?
Yes, our PNG compressor fully preserves alpha channels and transparent areas without affecting transparency quality.
Is it safe to upload PNG files?
Yes, all files are processed locally in your browser and automatically deleted after compression. We don't store your images on servers.
What's the maximum PNG file size?
You can upload PNG files up to 10 MB in size. For larger files, we recommend reducing resolution first.
