How It Works

Turning photos, scans, and receipts into a unified PDF document is a daily task, but uploading personal pictures to unknown cloud servers exposes your privacy. Pexlii creates professional PDF files directly on your device using client-side binary construction. When you select images, your browser reads each file into memory and calculates its native aspect ratio and pixel dimensions. When you select standard paper sizes like A4 or US Letter, the tool calculates the appropriate margins and scales each image proportionally so nothing gets stretched or cropped. Using pdf-lib in browser memory, our tool creates a fresh PDF structure, adds individual pages, embeds the raw image bytes directly into PDF image objects, and builds the document cross-reference table. The resulting PDF is produced instantly on your machine with no network delays, preserving maximum image clarity and total confidentiality.

🔒 100% Client-Side In-Browser Execution: All processing occurs locally in your device memory. No files, documents, or data are transmitted over the internet or stored on remote servers.
