About PDF
PDF (Portable Document Format) was developed by Adobe Systems in 1993 and standardized as ISO 32000 in 2008 after Adobe submitted the format for standardization. PDF is the world's leading format for cross-platform document exchange, preserving layout, fonts, images, and interactive elements exactly – regardless of the display device or operating system. The format is based on a mixture of text, vector graphics, and raster images and supports forms, digital signatures, annotation features, and JavaScript actions. PDF/A, a subset for long-term archiving, is the mandatory format for documents subject to retention requirements in government agencies and enterprises. The file structure enables incremental saving, where changes are appended without rewriting the entire file. PDF 2.0 (ISO 32000-2, 2020) brought improvements in accessibility and security. Criticisms include large file sizes when embedding fonts and images, as well as the difficulty of reliably extracting PDF content – which is why OCR-based conversion tools like wandlio are needed to transform scanned PDFs into editable formats.
Why convert JPG / PNG → PDF?
JPG (JPEG) is the most widely used image format worldwide, supported by virtually every camera, browser, and image app. It uses lossy DCT compression that degrades quality with each save and doesn't support transparency. Converting to PDF is required when you need lossless compression (PNG for screenshots/graphics), transparency support, or want to use a modern format with better compression like AVIF or WebP. For archiving and professional editing, PDF is often the better choice since it produces no compression artifacts and maintains quality across repeated saves.
