Image to PDF

Why Convert Images to PDF?

Scanning documents with your phone camera creates individual image files — sometimes dozens of them. Combining those images into a single PDF creates a clean, shareable document that looks professional and is easy to archive. Job applications, receipts, contracts, whiteboard photos, and handwritten notes all benefit from being organized into a single PDF.

According to Fortune Business Insights (2024), the global document scanner market is valued at $6.19 billion. Quocirca (2024) reports that only 11% of organizations are fully paperless, and 59% plan to increase investment in scanning and digitization.

PDFJolt combines your images into a PDF entirely in your browser using WebAssembly. Your photos never leave your device — making it safe for IDs, financial documents, medical records, and anything else you'd rather keep private.

How PDFJolt Converts Images to PDF

PDFJolt uses pdf-lib, a proven open-source library, to create PDF documents entirely client-side. Each image is embedded into its own page, preserving the original aspect ratio. You control the page size, margins, and page order — all before creating the final PDF.

Three page size options are available:

• A4 (210 × 297mm) — International standard paper size. Best for documents that will be printed in most countries.
• Letter (8.5 × 11in) — US standard paper size. Best for documents printed in North America.
• Fit to Image — Page size matches the image dimensions exactly. Best for photo collections and portfolios where you don't want white margins.

Common Use Cases

Phone-Scanned Documents

Scanned 15 pages of a contract with your phone camera? Drop all the photos into PDFJolt, drag them into the correct order, and download a clean single PDF. Much more professional than emailing 15 separate image files.

Job Applications

Many job portals require a single PDF containing your resume, cover letter, certifications, and ID. Use PDFJolt to combine photos of your documents into one organized PDF file.

Receipt Collections

Freelancers and business travelers can photograph receipts throughout the week, then combine them into a single PDF for expense reporting. Much easier to submit one file than 20 separate images.

Photo Portfolios

Photographers and designers can combine selected images into a PDF portfolio. Use "Fit to Image" page size to preserve original dimensions without cropping or white space.

Supported Image Formats

PDFJolt accepts JPG/JPEG, PNG, and WebP images. All formats are normalized during processing to ensure compatibility with the output PDF. JPEG images maintain their compression, while PNG images preserve transparency (rendered on a white background in the PDF).

Privacy & Security

Every major image-to-PDF tool — iLovePDF, Smallpdf, PDF24, FreeConvert — uploads your images to their servers for processing. PDFJolt is fundamentally different: your images never leave your browser. The PDF is created entirely in your device's memory using WebAssembly. No server upload, no cloud storage, no data collection, no account required.

This makes PDFJolt the safest choice for combining sensitive images into PDFs. Whether you're working with scanned IDs, medical documents, financial records, or personal photos — your data stays on your device.

Tips for Best Results

• Drag thumbnails to rearrange the page order before creating your PDF. The order you see is the order in the final document.
• Use "Fit to Image" page size for photos and portfolios to avoid white margins around images.
• Use A4 or Letter for document scans so the output matches standard paper sizes for printing.
• PDFJolt auto-detects whether each image is portrait or landscape and orients the PDF page accordingly.
• For the cleanest results, ensure your source images are well-lit, properly cropped, and at reasonable resolution (300+ DPI for text documents).
