Why archive scanned documents as PNG instead of JPEG?

JPEG is a lossy format — every re-save degrades quality. PNG is lossless, ensuring that archived documents remain pixel-perfect indefinitely, regardless of how many times they are accessed or migrated.

Does converting to PNG increase storage requirements?

PNG files are typically larger than JPEGs. For archival purposes, the storage overhead is generally justified by the preservation guarantee. Deliteful applies PNG optimization to minimize the size difference.

Can I batch-convert a large set of existing JPEG scans?

Yes. Deliteful supports up to 50 files or 2GB per batch, making it practical to migrate existing JPEG scan libraries to PNG in manageable sessions.

Are CMYK JPEG scans from office copiers supported?

Yes. CMYK JPEGs are automatically converted to RGB during processing, producing PNG output compatible with standard document management systems.

Convert JPEG Scans to PNG for Long-Term Document Archiving

Organizations archiving scanned documents as JPEGs risk cumulative quality loss if files are ever re-exported, re-compressed, or migrated between systems. Converting scanned JPEG images to PNG before archiving locks in current quality permanently — no future re-compression can degrade a PNG file.

Document archiving workflows that rely on JPEG introduce a hidden fragility: every time a JPEG is opened and re-saved by any downstream process — format migration, thumbnail generation, OCR preprocessing — quality degrades. PNG is lossless, meaning a file archived today will be bit-for-bit identical to a file accessed in ten years. For compliance-sensitive organizations, this is not a minor consideration.

Deliteful processes batches of up to 50 JPEG scans per session, preserves exact pixel dimensions, and outputs optimized PNGs that are compact while remaining fully lossless. CMYK JPEGs — common in scanned documents from older copier-scanners — are automatically normalized to RGB. The result is a consistent, format-stable archive that ingests cleanly into any document management system.
