Singapore's Duplicate Image Problem: The Numbers Driving a Digital Clean-Up

Singapore's digital infrastructure is carrying dead weight. Across the city-state's network of public-sector websites, commercial platforms and institutional media libraries, duplicate image files — identical or near-identical visual assets stored multiple times — account for an estimated 20 to 30 percent of total image storage consumption, according to industry benchmarks published by cloud storage analysts tracking Asia-Pacific data centres in 2025. That translates, at Singapore's commercial cloud storage rates, to tens of thousands of dollars in unnecessary monthly expenditure for mid-sized organisations alone.

The issue has sharpened in urgency because Singapore's Smart Nation and Digital Government Group has been pushing government agencies toward leaner, more efficient digital infrastructure ahead of its 2030 digitalisation targets. When storage waste compounds across dozens of statutory boards and ministry microsites, the aggregate cost is not trivial. The Infocomm Media Development Authority, which oversees Singapore's digital standards framework, has flagged data hygiene as a component of its ongoing Digital Infrastructure Map review.

What the Data Actually Shows

The mechanics of duplication are straightforward but expensive. A single product photograph uploaded to an e-commerce merchant's portal at Lazada's Singapore operations, for instance, may be stored in up to six separate resolution variants — thumbnail, mobile, desktop, retina, compressed and original — and then duplicated again each time a seller re-lists the same product. At scale, across hundreds of thousands of listings, that multiplication effect is substantial. Industry data from storage optimisation firms operating in the Asia-Pacific region suggests e-commerce platforms in Southeast Asia waste between 18 and 25 percent of total object storage on resolvable duplicate assets.

For Singapore's government portals, the numbers take a different shape. The Government Technology Agency, known as GovTech and headquartered at Sandcrawler Building in one-north, Buona Vista, manages the backend infrastructure for over 1,600 government digital services. A 2024 internal audit cycle — details of which were referenced in GovTech's annual report — identified media asset rationalisation as a priority action item. The agency did not publish a specific dollar figure for duplicate image costs, but comparable exercises in comparable city-state administrations have produced savings of between five and fifteen percent on overall media storage bills after deduplication programmes were completed.

At the National Library Board, whose digital preservation mandate includes maintaining image archives across its network of 26 public libraries from the flagship Victoria Street branch to neighbourhood libraries in Tampines and Jurong, deduplication tools have been integrated into the NLB's Digital Preservation Framework since 2022. The NLB's framework uses hash-based comparison — a method that generates a unique fingerprint for each image file and flags exact-match duplicates automatically — to manage a digitised collection that runs into the millions of individual assets.

What Comes Next for Businesses and Agencies

The practical stakes are rising. Singapore's commercial colocation and cloud hosting rates have increased since 2023, with standard object storage at local data centres now priced between SGD 0.025 and SGD 0.035 per gigabyte per month, depending on tier and provider. For an organisation storing 50 terabytes of image data — not unusual for a media company or large retailer — eliminating a 25 percent duplication rate would free roughly 12.5 terabytes, a saving that compounds month on month.

Perceptual hashing tools, which catch near-duplicate images that differ only in minor compression artefacts or slight cropping, are increasingly available to small and medium enterprises at low cost. Platforms such as Singapore-based tech consultancies operating out of the Mapletree Business City cluster in Alexandra have begun offering automated media library audits as a standalone service, typically priced between SGD 2,000 and SGD 8,000 for a full organisational review depending on archive size.

For organisations that have not yet run a deduplication audit, the starting point is a storage inventory. Any media library that has grown through staff turnover, platform migrations or bulk content imports since 2020 is likely carrying significant redundancy. The cost of doing nothing is measurable, and the tools to fix it have never been cheaper or more accessible in Singapore's market.
