San Francisco's City Websites Are Drowning in Duplicate Images — Here's What the Numbers Reveal

San Francisco's municipal digital infrastructure is carrying thousands of redundant image files across its public-facing websites, a problem that city technology auditors have been flagging internally since at least 2024 — and one that carries measurable costs in storage fees, page-load times, and ADA compliance failures. The scale is larger than most residents would expect.

The issue matters now because the city's Department of Technology is midway through a two-year consolidation of more than 40 separate agency websites onto a unified SF.gov platform, a project that launched formally in January 2025. As content from legacy sites gets migrated, duplicate images — the same stock photo of City Hall's rotunda uploaded six or seven times by different departments, for instance — are being carried wholesale into the new architecture. Every redundant file adds to cloud hosting overhead and slows delivery to end users on mobile connections.

What the Numbers Actually Look Like

Internal content audits reviewed by The Daily San Francisco show that city agency web properties, taken together, housed an estimated 280,000 image assets as of early 2026. Across that pool, duplication rates in migrated content can run as high as 30 percent on sites that haven't undergone manual review — a figure consistent with what digital asset management firms report industry-wide for large public-sector migrations. For a city the size of San Francisco, that translates to tens of thousands of unnecessary files sitting in Amazon Web Services or Microsoft Azure buckets, each drawing storage and bandwidth costs that compound monthly.

The San Francisco Municipal Transportation Agency's public web portal — which covers both Muni and the city's bike-share and parking programs — ran a content cleanup in March 2026 and removed more than 4,200 image duplicates from its media library. The SFMTA communications team declined to confirm the exact storage savings on the record, but industry benchmarks suggest that eliminating that volume of unoptimized JPEG and PNG files from a mid-sized government site typically reduces image-related bandwidth costs by 15 to 20 percent annually. At average AWS regional pricing, that's a meaningful line item.

The Department of Public Health's SFDPHrising.org portal, which hosts program information for everything from Tenderloin fentanyl response resources to Bayview-Hunters Point community health clinics, has been flagged separately for image redundancy issues that also create accessibility gaps. When the same image is uploaded multiple times under different filenames, alt-text metadata is rarely duplicated correctly — meaning screen readers used by visually impaired residents often encounter blank or mismatched descriptions. Under Section 508 of the federal Rehabilitation Act, that's a compliance failure, not just a technical inconvenience.

The Cost of Doing Nothing

The financial picture becomes clearer when you factor in the city's existing technology contracts. San Francisco spent roughly $4.2 million on web infrastructure and content management licensing in fiscal year 2024-25, according to budget documents published by the Controller's Office. Bloated asset libraries don't just cost money — they slow the sites that residents in the Mission District or the Excelsior use to find shelter beds, report potholes, or check Muni arrival times.

Digital asset management specialists recommend that large organizations run automated deduplication scans quarterly, cross-referenced against a master media library. The city's Department of Technology has piloted one such tool — a platform called Bynder — on a limited basis across three agency sites since February 2026, but a citywide rollout has not been scheduled or budgeted as of this reporting.

For city residents and the advocacy groups that watch San Francisco's technology spending — including Code for America's San Francisco brigade, which operates out of a co-working space on Market Street near Civic Center — the practical advice is straightforward: pressure your district supervisor to ask the Department of Technology for a public-facing report on the SF.gov migration's image audit progress before the project's scheduled completion date of December 2026. The numbers exist. They just haven't been published.
