BufferZone vs OptiPNG

BufferZone

Security & Privacy

BufferZone is a free firewall program that protects your computer from malware, hackers, and internet threats. It works by isolating your web browser and email client into a virtual container, preventing threats from accessing the rest of your computer if you happen to visit an infected website or open a malicious email attachment.

OptiPNG

Photos & Graphics

OptiPNG is an open-source PNG optimizer that reduces the file size of PNG images while preserving transparency. It works by applying lossless compression and interpolation methods.
