JPG / PNG to PDF
Convert images to PDF. Add multiple JPG, PNG or WebP files, set page size and margins, and download a professionally formatted PDF. All processing in your browser.
Images as Documents — Why the Format Change Matters
A JPG file is just an image. A PDF is a document. The distinction matters more than it seems. Government portals, employer HR systems, university submission portals, insurance companies and legal filing platforms almost universally require PDF format for uploaded documents — not individual image files. When you photograph your passport, scan a signed contract, or capture a receipt on your phone, you get an image. Converting it to PDF turns that image into a submittable, archivable, professional document that renders identically on every device and platform. Our free JPG to PDF converter handles this conversion in your browser in seconds, with full control over page size, orientation and margins.
Up to 20 Images, One PDF — Controlling the Order
Add up to 20 JPG, PNG or WebP files in a single operation. Each image appears as a row in the file list with a thumbnail preview. Use the ↑↓ arrow buttons to reorder images before converting — the first image in the list becomes page 1 of the output PDF, and so on. Remove unwanted images with the ✕ button. The file list also shows the name and size of each image so you can confirm you have the right files before converting. This ordered list approach gives you precise control over the page sequence — important for multi-page documents like multi-page scan sets, photo portfolios and instruction sequences.
Page Size, Orientation and Margin Explained
Page size determines the PDF page dimensions. A4 is the international standard used in Europe, Asia and most of the world. Letter is the US standard. Legal is the extended US format used for contracts and legal filings. Fit to Image creates a page exactly as wide and tall as the image — ideal for photos and diagrams where you want zero white space. Orientation (Portrait or Landscape) rotates the page layout — use Landscape for wide panoramic images or horizontal charts. Margin controls the white border around each image on its page: 0 for edge-to-edge coverage, or up to 80px for a clean framed look. The image scales automatically to fill the available space while preserving its aspect ratio.
Image Quality Is Preserved Exactly
JPEG images are embedded into the PDF as-is, without any re-encoding or re-compression. The image data bytes from your original file go directly into the PDF page structure — meaning the output image quality is byte-for-byte identical to the source. PNG images preserve their alpha channel transparency. No quality is lost at any stage. The only transformation applied is geometric: the image is scaled (up or down) to fit the available page area while maintaining its original aspect ratio.
Common Uses for Image-to-PDF Conversion
- Identity document submission: Passport, national ID and visa document submissions to government portals almost always require PDF — combine front and back images into a single 2-page PDF
- Scanned document assembly: Convert a set of phone camera scans into one PDF, then use our Merge PDF tool to combine it with other documents for a complete submission package
- Expense receipt batching: Convert all receipt photos for a period into one PDF, then use our Compress PDF tool to reduce the file size before submitting to accounting
- Photo portfolio: Create a printable or shareable portfolio PDF from a selected set of high-resolution images
- Product catalogue: Compile product photography into a professional multi-page PDF brochure
- Design deliverables: Export mockup or design screenshots as a PDF document for client review and sign-off
Working With the Output PDF
After downloading your converted PDF, you can work on it with the full range of PDF tools. If the file is too large to email, run it through our Compress PDF tool. If you need to add a watermark or page numbers for official documents, use our Watermark PDF or Add Page Numbers tools. And if you need to combine your image PDF with additional text PDFs, our Merge PDF tool handles that in one step.
No Upload, No Account, No Tracking
All image processing and PDF creation happen locally using pdf-lib running in your browser tab. Your images are never transmitted to ToollyX servers. This makes the tool safe for converting sensitive images — identity documents, medical scan photos, signed contracts and confidential design assets — that must not be uploaded to cloud services.
