How to Compress Scanned Documents to Save Cloud Storage
Compress PDFThe Problem
Scanned documents are notoriously large — a single page can be 5-10MB. Storing hundreds of scanned PDFs of contracts, invoices, and records eats through your Google Drive, Dropbox, or OneDrive storage quickly. At this rate, you'll hit your storage limit in months and face either deleting files or paying for more storage.
The Solution
SprinkleTools' compression dramatically shrinks scanned PDFs by optimizing the embedded images while keeping text fully readable. Free up gigabytes of cloud storage without losing any documents — a 10MB scan typically compresses to 2-4MB with no visible quality difference.
How to Do It
Open the Compress PDF tool on SprinkleTools
Upload your scanned document
Select medium or strong compression for maximum savings
Download the smaller file
Replace the original in your cloud storage
Repeat for all scanned documents to reclaim storage space
Frequently Asked Questions
How much space will I save?
Scanned PDFs typically compress 60-80%. A 10MB scan becomes 2-4MB. For a folder of 100 scanned documents, you could reclaim 500MB-800MB.
Will text still be readable after compression?
Yes — text remains fully legible. Only embedded image quality is slightly reduced, which is invisible at normal viewing zoom.
Can I compress multiple files?
Process one at a time, or merge them first with the Merge PDF tool then compress the combined file.
Does this work for scanned photos too?
Yes — any PDF containing images benefits from compression, including scanned photos, diagrams, and charts.
