When authenticity fights compression temptation
“Lossless” really means refusing JPEG pit stops before PDF envelopes—forensics and brand guardians sniff altered histograms instantly. Prefer single-hop wraps or vector overlays that record coordinates honestly. Massive PNGs amplify subpixel rendering deltas between Retina captures and projector scrutiny. Ai2Done foregrounds progress during faithful encapsulation; log hashes for raw PNG siblings whenever PDF metadata churn threatens audit theater. Transparency stays intact—yet matte assumptions still deserve multi-reader QA.
Lossless wrap in three steps
- Ban intermediate lossy codecs—archive originals.
- Upload PNGs, wrap into PDF while watching progress.
- Record hashes / DPI metadata beside filings.
