Combine 1–50 local PNG, JPG or WebP images into one PDF in the displayed order. Drag to reorder or use the move buttons. Choose original image dimensions or centered A4 portrait pages with proportional fitting and 24-point minimum margins Parses and structures office document payloads locally in memory without transmitting private company files to external servers.
Document parsing & data extraction pipeline
Performs non-destructive manipulation of Portable Document Format (PDF) binary object streams in accordance with ISO 32000-1 and ISO 32000-2 (PDF 2.0). Operates on underlying PDF cross-reference tables (XRef), catalog dictionaries, page trees (/Pages), and content streams via pdf-lib and PDF.js. Implements symmetrical margin cropping based on existing CropBox / MediaBox origin coordinates [x, y], executes 90-degree page rotations, merges/splits page trees, and preserves AcroForm interactive form fields, annotations, and bookmarks.

File size & structure constraints
Operational constraints and validation boundaries: Original mode uses one PDF point per image pixel. A4 is 210×297 mm and may enlarge small images; no image is cropped. JPEG keeps its compressed image stream; PNG is decoded to RGB/alpha and compressed into PDF. WebP is decoded by the browser and re-encoded as PNG; animation becomes a single decoded frame. WebP canvas output is limited to 32,000,000 pixels and 16,384 pixels per side. No EXIF orientation normalization. Original metadata is neither guaranteed to be retained nor completely removed. No OCR, color-management or print-device verification; large images can exhaust browser memory.
PNG/JPEG/WebP Images to PDF parses structured OpenXML and PDF data locally. Review exported tables or sheets against original files.
Zero-upload document security boundary
File buffers and document assets in PNG/JPEG/WebP Images to PDF are processed in-memory via local browser APIs with zero file uploads to CZOA servers.
