Frequently Asked Questions

Are my images uploaded to a remote server?

Never. Every tool on PNGZO.com runs 100% inside your browser using HTML5 Canvas, UPNG.js, and JSZip. Confidential logos, unreleased UI mockups, and personal photos never leave your computer.

How does the 8-bit PNG compressor reduce file size so much?

Standard PNGs store 32 bits per pixel. When you enable Smart Compression, PNGZO uses the UPNG.js quantizer and pako DEFLATE encoder to write a true 8-bit indexed PLTE and tRNS chunk, cutting file weight by 60–80%.

How do I create a die-cut sticker with a white border?

In the Magic BG & Alpha tab, remove your background first, then drag the Sticker Outline Thickness slider between 6px and 12px. You can also enable Auto-Trim Transparent Whitespace to crop tightly around the sticker border.

Is PNGZO.com free for commercial projects?

Yes. There are no watermarks (unless you add your own in the Watermark Studio), no daily file count paywalls, and no account sign-up required.
