Image to PDF

Convert JPG, PNG, and other images into a PDF. Choose page size, orientation, margins, and image fit.

How to Use

Upload image files

Add JPG, PNG, WebP, or GIF files. Multiple images each become one page in the output PDF.

Choose page size and orientation

Select A4, Letter, or other paper size and Portrait or Landscape orientation.

Set image fit mode

Choose Fit, Fill, or Original Size to control how the image is placed on each PDF page.

Convert and download PDF

Click 'Convert to PDF' and download the resulting document with each image as a separate page.

Converting Images to PDF

This tool converts one or more images into a PDF document using jsPDF, a pure JavaScript PDF library. Choose your paper size and whether images should scale to fit, fill, or render at their original resolution.

Real-World Examples & Use Cases

Scanning Documents with a Phone Camera

Smartphone camera apps and scanning apps capture documents as JPEG images. Converting those images to PDF produces a standard document format for sharing and filing. A small business owner photographing receipts, contracts, or invoices with a smartphone needs to convert those JPEGs to PDF to email them to an accountant or store them in a document management system. The PDF format preserves the image quality, adds standard document metadata, and produces a file that can be opened by PDF readers on any platform including email clients and operating systems.

Artwork and Photography Portfolio Creation

Visual artists, photographers, and designers compile image collections into PDF portfolios for sharing with clients, galleries, and employers. A photographer converting a series of portfolio images to PDF creates a single, self-contained presentation file that displays consistently across all devices and email clients without requiring the viewer to have specific image viewing software. Each page of the PDF contains one image, and the PDF itself is shareable as a single file without a ZIP archive or file folder structure.

Company ID and Document Verification Submissions

Government agencies, banks, universities, and HR departments often require identity documents and supporting materials submitted as PDFs. Passport photos, driver's license scans, utility bill photos, and bank statement images captured with a phone must be converted to PDF for formal submission forms. Many submission portals accept only PDF files and reject raw image files. Converting images to PDF meets format requirements without needing desktop software or third-party apps.

Product Manuals and Technical Documentation

Technical writers and product managers create instruction documents that consist primarily of annotated screenshots, photographs of hardware, and diagrams. Capturing these visual elements as PNG images and converting them to PDF produces print-ready documentation. Product photography processed in photo editing software and exported as JPEG files can be assembled into a multi-page product catalog PDF by uploading images in sequence. The resulting PDF is print-ready and maintains image quality better than embedding images in word processor documents.

How It Works

Image to PDF conversion using jsPDF: Core workflow: 1. Load image via FileReader.readAsDataURL() 2. Create Image element to get natural dimensions 3. Initialize jsPDF: const doc = new jsPDF({ orientation, unit: 'mm', format: pageSize }); 4. Calculate image placement: Page dimensions (A4): 210mm × 297mm Available area (with margins): e.g. 190mm × 277mm Fit mode: scale = Math.min(availWidth/imgW, availHeight/imgH) x = (pageW - imgW×scale) / 2 (center horizontally) y = (pageH - imgH×scale) / 2 (center vertically) Fill mode: scale = Math.max(availWidth/imgW, availHeight/imgH) 5. Add image to page: doc.addImage(dataUrl, format, x, y, width×scale, height×scale) 6. For multiple images, add pages: doc.addPage(); before each subsequent image 7. Save: doc.save('output.pdf') Common paper sizes: - A4: 210 × 297 mm (international standard) - Letter: 215.9 × 279.4 mm (US/Canada) - Legal: 215.9 × 355.6 mm - A3: 297 × 420 mm

Frequently Asked Questions

How many images can I convert into a single PDF?▼

There is no fixed limit — each image becomes one PDF page. Practical limits are your device's RAM and browser memory. For most use cases (10–50 images), the tool works without issues. For large batches (100+ high-resolution photos), browser memory usage may become significant. Very large image files (20+ MB each) should be resized first using the Image Resizer to avoid browser memory issues.

What image dimensions should I use for standard paper sizes?▼

At 300 DPI (print quality): A4 (210×297mm) requires 2480×3508 pixels; Letter (8.5×11in) requires 2550×3300 pixels. At 150 DPI (decent screen quality): A4 needs 1240×1754 px; Letter needs 1275×1650 px. At 72 DPI (screen only): A4 needs 595×842 px; Letter needs 612×792 px. For documents shared digitally only (not printed), 150 DPI provides a good balance of quality and file size.

Will the PDF look blurry if my images are low resolution?▼

If you choose 'Fit to page' and the image is low resolution, it will appear blurry when scaled up to full page size. Using 'Original size' places the image at its actual pixel dimensions without upscaling. For professional print quality, use images with at least 150–300 pixels per inch at the final printed size. Screen-quality images (72–96 DPI) appear acceptable when viewed on screens but blur noticeably when printed.

Can I control the order of pages in the multi-image PDF?▼

Yes. In most implementations, images are added to the PDF in the order they appear in the file list. You can reorder files by uploading them in the sequence you want, or by reordering using the tool's list interface if available. The first image uploaded becomes page 1; the last image becomes the final page.

Is the resulting PDF text-searchable?▼

No. Image-to-PDF conversion embeds photographs of your content rather than selectable text. The resulting PDF contains only raster images — the content is not searchable, copyable, or accessible to screen readers. For searchable PDFs from document images, you need Optical Character Recognition (OCR) software — tools like Adobe Acrobat (paid), ABBYY FineReader, or online OCR services can analyze image content and produce searchable PDF text layers.
