When provenance varies but the envelope must feel official
Procurement screenshots, smartphone proofs, and flatbed outputs rarely share codecs yet belong to one audit thread. Merging formalizes chronology so reviewers replay decisions without drowning in attachments. Transparent PNG overlays surprise stakeholders when stacked atop tinted backgrounds; multi-generation JPEG ghosts surfaces under magnification. Ai2Done sequences drag-and-drop batches with explicit progress—preview stamped pages before sealing dozens behind one checksum-friendly PDF. Pair deliveries with manifest hashes; if investigators later need pristine PNGs, namespace originals separately from merged bundles.
Merge mixed images in three steps
- Timeline-order assets and insert divider plates if policies demand.
- Upload mixed formats, normalize orientation, merge.
- Verify stamp stacking and continuity; log hashes on manifests.
FAQs: mixed merges
Transparency clashes?
Flatten onto consistent backgrounds before PDF wrapping.
JPEG softness irreversible?
Document resolution limits; retain untouched originals.
Future single-page extractions?
Split PDF tooling or parallel PNG archives—plan upfront.
