Convert JPG and PNG Images to PDF

When images are added, the client runtime reads their binary headers to determine pixel dimensions and aspect ratios. The `pdf-lib` engine creates a new PDF document object, establishing pages with exact geometric measurements based on standard ISO 216 dimensions: A4 (595.28 x 841.89 points / 210 x 297 mm), US Letter (612 x 792 points / 8.5 x 11 inches), A3 (841.89 x 1190.55 points / 297 x 420 mm), or Auto-Fit matching original image dimensions. Images are drawn centered with uniform proportional scaling to prevent visual distortion.

The compiler natively handles standard web image codecs without lossy intermediate transcoding:

• JPEG (.jpg / .jpeg): Embedded directly as native DCT-encoded image streams, ensuring ultra-fast compilation and compact PDF file size.
• PNG (.png): Decoded with lossless alpha channel support, rendering crisp graphical illustrations, screenshots, and vector scans with sharp contrast.
• WebP (.webp): Decoded via HTML5 Canvas rasterization, allowing modern web photographs and captures to be seamlessly integrated into standardized PDF pages.

Compiling photos of national ID cards, driver’s licenses, tax receipts, or confidential corporate expense vouchers demands total data security. By performing 100% of memory allocation, image decoding, and PDF serialization within your local device’s browser sandbox, no image data ever leaves your computer or phone, fully satisfying the stringent requirements of European GDPR and international data protection laws.

Merging photos into organized PDF files streamlines essential daily processes:

• Accounting & Expense Claims: Bundling multiple receipts, invoices, and tickets into a single chronological PDF report for reimbursement.
• Administrative & Legal Procedures: Combining photographic evidence, utility bills, and official identity documents into a single dossier.
• Education & University Homework: Stitching multiple photos of handwritten class notes, exams, or assignments into a unified PDF for online portal submission.
• Creative Portfolios & Architecture: Packaging high-resolution render images, design mockups, and photography collections into a clean client presentation.

To ensure optimal printing and presentation, you can toggle between Portrait (Vertical) and Landscape (Horizontal) orientations. Configurable margin presets (No Margin 0 mm, Small 5 mm, Normal 10 mm) calculate precise bounding boxes, ensuring that full-bleed photos fill the entire sheet or maintain clean printable borders suitable for physical hole-punch binders.
