About converting JPG to PDF
Why convert images to PDF?
Three reasons. First, PDF is a universal format. Every operating system can open a PDF, every printer can print one, and every email client can attach one. JPG files are also universal, but only a single image per file. Combining multiple images into one PDF gives you a single deliverable that holds the whole set in a specific order. Second, PDF supports text overlays, page numbers, and watermarks (which we offer on other tools), so converting first lets you add those later. Third, many forms and portals (visa applications, school assignments, expense reports, insurance claims) require submissions as a single PDF, not as multiple image attachments.
How the conversion works
The tool uses the pdf-lib JavaScript library running in your browser. When you drop images, the tool reads their dimensions and shows thumbnails. When you click Convert, pdf-lib creates a new PDF, embeds each image as a page in the order you specified, and downloads the result. JPG images are embedded losslessly via the embedJpg API, and PNG images via embedPng (preserving transparency over white background when needed). No re-encoding happens, so quality is identical to the source images.
JPG vs PNG vs WebP as input
JPG (JPEG): Lossy compression, best for photos and natural images. Smallest file size for photographic content. Use this when you have photos from a camera or phone.
PNG: Lossless compression, supports transparency. Larger file size than JPG for photos but better for screenshots, diagrams, and graphics. PNG transparency renders over a white background in the PDF.
WebP: Modern format from Google with better compression than JPG/PNG. Browser-supported and embeddable into PDF. Less common but accepted by the tool.
Picking the right page size
Fit to image: The PDF page matches each image's aspect ratio. No cropping, no scaling, no white space. Use this when the destination is digital-only and you want zero modification of image dimensions.
A4 (210 × 297 mm): The international standard for documents. Use this for printing in most countries outside North America and for documents intended for international audiences.
US Letter (8.5 × 11 in): Standard in the US and Canada. Use for documents intended for North American audiences or printers.
US Legal (8.5 × 14 in): Longer than Letter. Used for legal documents and contracts.
Orientation choices
Auto: Each image gets its own orientation based on aspect ratio. Wider-than-tall images become landscape pages, taller-than-wide become portrait. Best for mixed image batches.
Portrait: All pages are portrait. Best for standard document layouts.
Landscape: All pages are landscape. Best for wide images like screenshots or panoramas.
Margin guidance
Choose margins based on your end use. None fills the entire page (good for photo books and full-bleed printing where you don't want any white border). Small (6 mm) is the standard for printed documents and prevents content being cut off at the edge of consumer printers. Medium (12 mm) matches typical office print margins. Large (25 mm) is for formal documents, bound reports, and academic papers where standard margins are required.
File size considerations
The output PDF is roughly the sum of input image sizes plus a small overhead (typically under 1 MB). The tool does not re-compress images. If your output PDF is larger than the email or upload destination allows, you have two options. First, compress the images before converting (use our Image Compressor with JPG output at 70-80 percent quality; you usually cannot tell the difference visually). Second, run the output PDF through our PDF Compressor after conversion, which re-encodes embedded images at a lower quality.
Privacy and security
Zero upload. Your images stay on your device. The tool fetches the pdf-lib library code from the network at first load, then everything happens locally. Open browser Developer Tools, switch to the Network tab, drop images, click Convert: you will see no outbound data transfers. This is the strongest privacy guarantee for personal photos (visa photos, ID scans, financial receipts, medical images).
How this compares to competitors
iLovePDF and SmallPDF both offer JPG to PDF tools that work by uploading your images, processing on their servers, and serving back the PDF. They delete uploaded files after a stated retention period (2 hours and 1 hour respectively). Both have free-tier daily task limits (2 tasks/day on free). Adobe Acrobat Online requires an account. Gizmoop's tool processes everything locally, has no limits, requires no account, and never sees your data. The trade-off: server tools may convert slightly faster for very large batches because cloud servers have more compute than a typical phone.
Combining with other tools
A common workflow: take photos with your phone, transfer to laptop, use our Image Cropper to crop each photo, use our Image Rotator to fix any sideways photos, then use this JPG to PDF tool to combine into one document. If the final PDF is too big for email, use Compress PDF afterward. To watermark or add page numbers, use Watermark PDF and Add Page Numbers PDF. Every step in this workflow happens in your browser with no upload at any step.
Mobile use
The tool works on iOS Safari 15+ and Android Chrome. Touch-friendly drag-and-drop. Mobile RAM is more limited, so very large batches (50+ high-resolution photos) may slow down or time out. For quick conversions of 5-20 phone photos, mobile works smoothly. For larger batches, use a laptop or desktop.
Frequently asked questions

Drop your JPG (or PNG, WebP) images into the tool above, pick a page size and orientation, and click Convert. The PDF generates in your browser and downloads instantly. No upload to any server. Add multiple images and drag them into the order you want; each image becomes one page in the output PDF.
Yes. Drop as many images as you need, drag to reorder, and the output is a single multi-page PDF with each image as its own page. This is the most common use case: combining receipts, ID photos, or scanned pages into one document.
No, never. The conversion uses pdf-lib running in your browser. Your images stay on your device. Verify in Developer Tools → Network: no upload requests occur during the conversion.
JPG (JPEG), PNG, WebP, and GIF (first frame). The tool detects the format automatically. Other formats (BMP, TIFF) are not supported directly; convert them to JPG or PNG first using our Image Converter.
For printing: A4 (most of the world) or US Letter (North America). For digital sharing only: "Fit to image" keeps the original image dimensions without cropping or scaling. For ID cards and small photos: any size works since the image is centered with margins.
No. JPG images are embedded into the PDF without re-encoding, preserving 100 percent of the original quality. PNG images are embedded losslessly. The PDF file size is roughly the sum of input image sizes plus a small overhead.
Yes. Pick None, Small (6 mm), Medium (12 mm), or Large (25 mm). Small margins are typical for printed documents. None is useful when you want the image to fill the page edge-to-edge, useful for photo books.
No hard limit. Practical browser memory handles dozens of high-resolution photos comfortably. For 100+ images, consider splitting into batches and merging the resulting PDFs with our Merge PDF tool.
No, because images contain no text data. The PDF will look like the images but cannot be searched or text-selected. If you need searchable text, the images first need OCR processing (convert image text to text data), which is a different tool.
iLovePDF and SmallPDF process images on their servers and have free-tier daily limits (2 tasks/day each). Gizmoop processes everything in your browser, has no limits, and adds no watermarks. The trade-off: server tools may convert slightly faster for very large batches because their cloud has more compute.
Yes, use our Image Rotator and Image Cropper before running the JPG to PDF tool. The cropped/rotated images become the PDF pages with their new orientation and dimensions.
Yes. The tool works in any modern mobile browser (Safari iOS 15+, Chrome Android). Touch-friendly drag-and-drop reordering. Mobile RAM is more limited, so very large image batches (50+ photos) may be slow.
Submit a single expense report to an employer or to a tax accountant. Many corporate expense systems accept only PDF; combining receipts into one PDF is easier than emailing 20 photo attachments. The same workflow applies to insurance claims and customs paperwork.
