Input must be a standard .pdf file; the extractor supports PDFs containing embedded images in common formats (JPEG, PNG, TIFF, WebP). Output options are .jpg and .png per image, and multiple images are packaged as a .zip for download. In typical desktop browsers (Chrome, Firefox, Edge) a single PDF up to ~50 MB works comfortably; on mobile Safari you may see issues above ~20–30 MB due to memory limits. The tool reliably lists up to ~200 extracted images per PDF before browser memory slows the process.
