Estimate image storage needs from file count, average size, and format. Plan capacity for JPEG, PNG, RAW, and WebP libraries.
Image storage requirements vary enormously by format and resolution. A 24-megapixel RAW photo is 25–50 MB, while the same scene as a JPEG is 3–8 MB. A PNG screenshot might be 500 KB, while a WebP version is 200 KB. For large image libraries—photo archives, e-commerce catalogs, medical imaging, or satellite imagery—accurate storage estimation is essential for capacity planning.
This calculator estimates total image storage from the number of images, average file size per format, and format distribution. It supports JPEG, PNG, RAW, WebP, TIFF, and HEIF formats with typical size ranges for common resolutions. You can model single-format libraries or mixed-format collections.
Whether you're planning a cloud-based Digital Asset Management (DAM) system, sizing a photographer's NAS, or budgeting for an e-commerce product image CDN, this tool gives you reliable storage projections.
Quantifying this parameter enables systematic comparison across environments, deployments, and time periods, revealing optimization opportunities that improve both performance and cost-effectiveness.
Image libraries grow fast. An e-commerce site with 100,000 products averaging 10 images each at 500 KB = 500 GB just for product photos. This calculator helps you plan storage, CDN, and backup capacity before running out of space. Precise quantification supports capacity planning and performance budgeting, ensuring infrastructure investments are right-sized for both current workloads and projected future growth.
total_storage = image_count × avg_size_per_image; with_thumbnails = total + (image_count × thumbnail_size)
Result: 342 GB total
100,000 images × 3.5 MB average JPEG size = 350,000 MB = 341.8 GB. Adding thumbnails (100K × 50 KB = 4.88 GB) brings the total to ~347 GB. With 3 backup copies, provision 1 TB+ of storage.
JPEG: 3–8 MB for 24 MP, lossy, universal support. PNG: 15–30 MB for 24 MP, lossless, large files. WebP: 2–5 MB for 24 MP, lossy+lossless, good browser support. HEIF: 1.5–4 MB for 24 MP, excellent compression, limited support. RAW: 25–50 MB for 24 MP, uncompressed sensor data. TIFF: 70–140 MB for 24 MP, lossless, used in print/medical.
A typical product has 5–10 images at 3 sizes each (thumbnail, listing, full). 50,000 products × 10 images × 3 sizes × average 200 KB = ~293 GB. Add original high-res files for future re-rendering: +500 GB. Total: ~800 GB for a medium e-commerce catalog.
Images are write-once-read-many—ideal for archival storage. Store originals on cold/archive storage with CDN copies on hot storage. Use content-addressable storage (CAS) to automatically deduplicate identical images.
Smartphone photos: 2–5 MB. DSLR at 24 MP: 5–12 MB. Web-optimized: 100–500 KB. The size depends on resolution, quality setting (1–100), and scene complexity. High-detail scenes compress less effectively.
RAW files are 5–10× larger than JPEG. A 24 MP camera produces ~25 MB RAW files vs ~5 MB JPEG. RAW preserves all sensor data for post-processing flexibility, while JPEG applies lossy compression in-camera.
For professional photography and medical imaging: always RAW (lossless, editable). For e-commerce and web: JPEG or WebP (smaller, fast delivery). For archives: both RAW original + JPEG derivative for quick access.
Thumbnails typically range from 10–50 KB each. For 100,000 images, thumbnails add 1–5 GB. Some systems generate multiple thumbnail sizes (small, medium, large), multiplying this by 2–3×.
No. PNG uses lossless compression optimized for graphics (flat colors, sharp edges). For photos, PNG files are 5–10× larger than JPEG with no visible quality improvement. Use PNG for screenshots, logos, and graphics only.
CDN storage typically holds optimized, resized versions (1/3–1/2 of original size). Origin storage holds originals. Plan CDN capacity at 30–50% of origin storage if you serve multiple sizes. CDN bandwidth is a separate cost.
