Why Should You Convert Photos or Images to PDF?

PDF (Portable Document Format) is a widely supported, consistent format for viewing, printing, and sharing documents. Here are the reasons to convert images to PDF:

• Universality: PDFs are viewable and printable on any device, OS, or browser—far more predictable than JPG, PNG, or WebP files, especially in bulk.
• Batching & Organizing: Quickly combine multiple images (scanned notes, ID proofs, receipts, certificates, artwork, etc.) into one neat, single document.
• Security: PDFs can be password-protected, signed, and locked for extra peace of mind.
• Preserve Quality: Keep high quality, color accuracy, and resolution—while also compressing for smaller file sizes.
• Easier Printing: Print images in sequence and right-sizes (A4, Letter, etc.) with standardized margins—no more odd crops or scaling issues.
• Professionalism: Submissions to government, corporate, and academic portals often require PDF, not JPG or PNG files.
