How it works

What is lossless compression?

Re-encodes the PNG through the browser's Canvas API and strips EXIF, ICC profiles, text chunks, and other metadata bloat. Every pixel stays identical — only the file size shrinks.

Lossy mode — when to use it?

Converts to WebP-quality JPEG-style compression behind the scenes via canvas toBlob. Gets 40–70% smaller files. Use when you're sharing on web/social and don't need strict PNG format.

Why is my saving small?

Already-optimised PNGs (from tools like Figma, Squoosh, or TinyPNG) have minimal metadata left. Lossless mode will save less. Switch to Lossy for bigger gains on those.
