Image to PDF Converter

About This Tool

Assumption: The keyword refers to a tool that converts one or more input image files into PDF documents, with options to merge into a single PDF or produce one PDF per image. Purpose & User Intent: This tool addresses the need to archive, share, or present image collections as PDFs. Primary users include designers, photographers, educators, admins, and IT staff who receive scans, photos, or screenshots and must distribute them in standardized PDF format, preserving input order and fidelity. Core Logic & Features: Required features include image ingestion for PNG/JPG/JPEG, GIF, BMP; preservation of input order; page size selection (A4, Letter, custom) and orientation; ability to merge into a single PDF or emit one PDF per image; basic image scaling to fit the page while preserving aspect ratio; and deterministic naming and output metadata. Optional/advanced features: batch processing in a single job, DPI control, image compression/quality settings, per-image validation and error reporting, and optional password protection for the resulting PDFs. Inputs & Outputs: Inputs consist of image_files (array of image metadata with name and size), page_size (string), orientation (portrait/landscape), merge_to_single_pdf (boolean), and optional output_quality (1–100). Outputs include pdf or multiple PDFs, with fields: total_pages, produced_file_size, and a downloadable link or blob. Algorithms & Calculations: The tool computes page layouts by scaling each image to fit the chosen page size while preserving aspect ratio and margins; order is preserved; when merge_to_single_pdf is true, images become consecutive pages in one document; otherwise, each image yields its own PDF. Error & Edge Cases: Invalid formats, empty input list, or images exceeding size limits trigger input validation errors; very large batches may be split or rate-limited; unsupported page sizes default to A4; missing required inputs produce structured errors, not UI messages. Industry/Region & Localization: Uses standard PDF formatting (ISO 32000), common page sizes (A4, Letter), and unit handling in mm/inches; respects locale for number formatting in advanced options. Assumptions & Exclusions: No OCR, editing, or watermarking; no data retention beyond the session unless user selects cloud storage; no password reset or encryption beyond optional protection; not responsible for source image legality.
