Frequently Asked Questions

Everything you need to know about converting images to PDF

How does browser-based JPG to PDF conversion work?
JPG to PDF conversion happens entirely in your browser using JavaScript. When you upload images, they are read locally using the File API. The pdf-lib library creates a new PDF document and embeds each image onto a page. You can customize page size, orientation, margins, and image fit before creating the PDF. No data is ever sent to any server — your files remain on your device at all times.
Is my data safe when using this JPG to PDF Converter?
Yes, 100%. Your images never leave your device. All processing happens locally in your browser using JavaScript. There are no file uploads, no server storage, and no third-party services involved. Your documents remain completely private and secure.
What image formats are supported?
Currently, JPG (JPEG) and PNG images are supported. Both formats can be mixed in the same conversion — simply upload all your images regardless of format and they'll be embedded into a single PDF. SVG and WebP support are planned for future updates.
Can I rearrange images before creating the PDF?
Yes! After uploading, you can drag and drop images to reorder them in any sequence. The order in the list determines the page order in the PDF. You can also rotate individual images and remove unwanted ones before conversion.
What page sizes are available?
Four page size options are available: A4 (210 × 297 mm, the international standard), Letter (8.5 × 11 in, US standard), Legal (8.5 × 14 in, for legal documents), and Auto, which automatically sizes each page to match the image's dimensions. Combined with Portrait, Landscape, or Auto orientation, you have full control over page layout.
How do image fit options work?
Four fit options control how each image is placed on the page: Fill — the image covers the entire page (may crop edges). Fit — the image fits within the page while preserving its aspect ratio. Stretch — the image fills the page but may appear distorted. Original Size — the image is centered at its native pixel dimensions without scaling.
What is the maximum number of images I can convert?
The tool supports up to 100 images per conversion. Each image can be up to 50 MB. For very large images or many images, the browser may need more memory and processing time. If you experience performance issues, try converting smaller batches.
Can I add margins to the PDF pages?
Yes. Four margin presets are available: None (full bleed, image fills the entire page), Small (5 mm), Medium (10 mm), and Large (20 mm). Margins are applied uniformly on all sides of each page.
Does this tool work offline?
Yes. Once the page has loaded and the PDF processing library has been fetched, all conversion functionality works without an internet connection since everything runs locally in your browser.
What makes ForgePlug's JPG to PDF Converter different from other tools?
Our tool is built as a premium workspace with a Figma-like experience, not a simple upload-convert-download form. Features include drag-and-drop image reordering, individual image rotation, flexible page size and margin controls, live image preview with zoom, a clean dark-mode-aware interface, and complete privacy — your files never leave your device.

How JPG to PDF Conversion Works

Learn about converting images to PDF and best practices

Why Convert Images to PDF?

Converting images to PDF is essential for creating professional documents, portfolios, presentations, and archives. PDFs preserve image quality, are universally viewable on any device, support printing with precise layout control, and can be easily shared and combined with other documents. Common use cases include scanning documents with a phone camera, creating photo albums, building client presentations, and archiving receipts or notes.

Understanding Page Size and Orientation

Page size determines the dimensions of each PDF page. A4 is the international standard used in most countries outside North America. Letter is the standard US business size. Legal is longer, used for contracts and legal documents. Auto matches each page to its image's dimensions for maximum flexibility. Choose Auto orientation to let each page's orientation match the image — ideal for mixed portrait and landscape image sets.

Tips for Creating Professional PDFs from Images

For the best results, use high-resolution images (300 DPI or higher) to ensure sharp output. For documents with mixed image orientations, use Auto orientation to let each page match its image. When creating a photo album or portfolio, use Fit mode to preserve image aspect ratios with Medium margins for a polished look. For forms or scanned documents, use Fill mode with No margins for a clean, full-page appearance.
