Dimensions Extractor

Extract and export dimensions from multiple images simultaneously for documentation, spreadsheets, or asset audits. Drop a batch of images—ten or ten thousand—and instantly receive an organized list pairing each filename with its width × height in pixels. Results export in multiple formats: plain text for quick reference, CSV for spreadsheet import, or JSON for integration with build tools and asset pipelines.

The extractor reads image headers without fully decoding pixel data, enabling rapid analysis even for large high-resolution files. Parallel processing handles batches efficiently while keeping your browser responsive. Results can be sorted by filename, width, height, or calculated aspect ratio to quickly identify what you need. All processing occurs locally—images never upload to any server, making the tool safe for proprietary or confidential assets.

Web developers auditing responsive image requirements quickly identify assets that don't meet size criteria. Designers documenting deliverables generate specification sheets automatically. Project managers creating asset inventories get structured data ready for tracking systems. Quality assurance teams verify that all images in a batch meet minimum or maximum dimension requirements. Anyone managing image collections—whether for websites, applications, or print production—will find batch dimension extraction invaluable for maintaining organized, documented asset libraries.
