Binary Chunk Level Filtering
Our engine parses the PNG chunk sequence (IHDR to IEND) and surgically excises non-critical metadata chunks.
- Strips tEXt, zTXt, and iTXt (AI prompts, workflows, and software tags)
- Removes eXIf chunks and embedded time stamps (tIME)
- Preserves IHDR, IDAT, PLTE, and tRNS chunks for bit-exact pixel fidelity
Verified Lossless Output
Processed PNG files retain original color profiles, alpha transparency, and exact dimensions with 0% compression loss.
- Zero image decoding artifacts
- Dual-scan verification before download
- Immediate local download with zero server uploads
