Why PNG Files Are Large (And How Compression Fixes That)
PNG (Portable Network Graphics) uses lossless compression and supports full 24-bit RGB color plus an 8-bit alpha channel for transparent backgrounds. Because PNG stores complete pixel accuracy, file sizes can balloon to several megabytes for complex screenshots, icons, or design mockups.
Our PNG compressor applies smart color quantization to shrink 24-bit images down to optimized 8-bit indexed palettes without sacrificing transparency or clean text edges.

How This Compares to TinyPNG
Popular tools like TinyPNG impose strict file size ceilings (5MB), batch limits (20 images), and require sending your graphics to third-party cloud servers.
TinyImageResizer runs directly in your browser tab with no arbitrary file limits, zero server uploads, and 100% data privacy.
