About PNG Compression
PNG (Portable Network Graphics) is a lossless image format widely used for web graphics, logos, and images requiring transparency. However, PNG files can be quite large. Our PNG compression tool uses advanced optimization algorithms to reduce file size significantly while maintaining visual quality. Unlike other compression tools that require uploading your files to a server, our tool performs all compression directly in your browser using modern web technologies. This means your images are completely private and never transmitted over the internet.

Frequently Asked Questions
Is PNG compression lossless?
Our tool uses advanced compression techniques that can be either lossless or near-lossless. While we optimise file size, the visual quality is preserved to ensure your files look identical to the originals.
Are my files safe and private?
Absolutely! All compression happens locally in your browser. Your files are never uploaded to our servers or transmitted over the internet. This ensures complete privacy and security for your files.
What's the maximum file size?
You can compress files up to 50MB each. For larger files, consider compressing them in smaller batches or using a different format.
How much can I reduce file size?
Compression results vary depending on the file content. Typically, you can expect 30-80% file size reduction. Files with large areas of solid colours compress better than complex files.
