Reduce Scanned Record PDF Sizes Before Long-Term Archive Storage
Document archives built on scanned paper records accumulate storage costs silently — a records room scanned at 300 DPI across 50,000 pages produces terabytes of PDFs that cost real money to store in S3, SharePoint, or a DMS. Deliteful compresses archival PDFs to a fraction of their scanned size while keeping text legible for retrieval and review.
Organizations that digitize physical records often scan at 300 DPI for future OCR compatibility, producing TIFF-heavy PDFs that average 1–3MB per page. A single filing cabinet digitized at that resolution can produce 50GB of PDFs. Multiplied across a department or a decade of records, storage costs become non-trivial — and the documents are almost never viewed at full resolution. Archival retrieval scenarios involve reading text and reviewing general document structure, not examining fine photographic detail.
Deliteful's Balanced mode is appropriate for most archival compression: it recompresses scanned images to reduce file size by 50–80% while keeping text and form fields legible at standard zoom levels. High Quality mode is better for records that may be printed or where fine printed text — such as small-print contracts or technical drawings — must remain sharp. Processing costs 15 credits per PDF; for large batches, paid plans provide the credit volume needed to work through a records backlog.

Frequently asked questions
- How much storage can I save by compressing scanned PDFs?
- Scanned PDFs are predominantly image data and compress more aggressively than native PDF exports. Balanced mode typically reduces scanned PDFs by 50–80%. A 10MB scanned document will commonly compress to 1.5–4MB, translating to meaningful storage savings at scale across thousands of records.
- Will compression affect OCR text layers that have already been applied to the scanned PDFs?
- Existing OCR text layers embedded in the PDF are generally preserved through compression, as they are part of the document's text structure rather than image data. However, Deliteful does not guarantee preservation of all PDF features across all document variants — verify OCR searchability on a sample document before compressing an entire archive batch.
- Is Balanced compression appropriate for legal hold documents that may be used in litigation?
- For documents on litigation hold, consult your legal team before modifying files in any way, including compression. Compression rewrites the PDF's internal structure, which may affect chain-of-custody documentation. High Quality mode minimizes changes to image content if compression of held documents is permitted.
- Can I process large batches of archival PDFs efficiently?
- Multiple PDFs can be uploaded in a single Deliteful session and processed with the same settings. Each PDF costs 15 credits. For archival projects involving hundreds or thousands of documents, a paid plan with higher monthly credit limits is necessary — the free tier's 20 credits covers only one compression per month.
