How the Image to PDF Converter works
The image to PDF converter merges one or more JPG, PNG, WebP, or GIF images into a single PDF document directly in your browser. Upload images, reorder the pages with drag and drop, select page size (A4, A3, Letter) and orientation, then download the finished PDF — all without uploading files to any server. Ideal for scanning documents with a phone camera, compiling multi-image reports, and creating portfolios.
Supported image formats and quality
The converter accepts JPEG (best for photographs, smallest file size), PNG (lossless, best for screenshots and documents with text), WebP (modern format with excellent compression), and GIF (converted to static frame). JPEG images embedded in PDF retain their original JPEG compression — the tool does not re-encode them, so image quality is preserved and file size stays predictable. PNG images are embedded as uncompressed bitmaps within the PDF, which keeps them crisp but produces larger file sizes.
Page size and image fitting options
The converter offers three image-fitting modes: Fit (image is scaled to fill the page width while maintaining aspect ratio, with white space at top and bottom if the image is narrower than the page); Fill (image fills the entire page, cropping sides if the aspect ratio does not match); and Original size (image is embedded at its actual pixel dimensions at 72 DPI, useful when you want precise control over layout).
Portrait vs landscape orientation
Portrait orientation (taller than wide) suits documents, scanned forms, and phone photos taken vertically. Landscape suits wide photos, diagrams, spreadsheets, and presentations. A4 portrait is 210×297 mm; A4 landscape is 297×210 mm. If you mix portrait and landscape images, the tool can auto-rotate each page to match the image orientation rather than forcing all pages to the same orientation — preventing wide images from appearing as rotated thumbnails.
Client-side privacy guarantee
All image-to-PDF conversion happens inside your browser using JavaScript PDF generation libraries. Your images are never transmitted to any server — conversion occurs entirely on your device. This makes the tool safe for sensitive documents: ID scans, medical records, financial statements, and legal documents can be converted to PDF without any risk of the files being logged, stored, or accessed by a third party.
Frequently asked questions
- Can I add multiple images to one PDF?
- Yes — upload as many images as you like. Each image becomes one page in the PDF. Drag the up/down arrows to reorder the pages before generating. This is useful for combining scanned documents, photos from an event, or sequential screenshots into a single file.
- What page sizes are supported?
- A4 (595×842 pt), A3 (842×1190 pt), US Letter (612×792 pt), and 'Fit to image' which makes each page exactly the image's pixel dimensions. You can choose portrait or landscape orientation for fixed page sizes.
- How do I convert a single image to PDF?
- Upload the image, choose your page size and fit mode, and click Generate PDF. Use 'Fit to image' if you want the PDF page to exactly match the image dimensions — useful for exact-size printing or preserving the original aspect ratio. For standard document pages, choose A4 or US Letter instead.
