How to Convert an Image to PDF

pdfimagesconversionjpgpng

Converting images to PDF is one of the most common conversion tasks — submitting receipts as PDF, bundling photos into a document, creating portfolios, packaging scans. Here’s the practical guide.

The fastest way

Use JPG to PDF (which handles all common image formats — JPG, PNG, WebP, HEIC, despite the name):

  1. Open JPG to PDF
  2. Drop in your images (drag in multiple to add several)
  3. Drag to reorder if needed
  4. Choose options (page size, orientation, fit)
  5. Click Convert
  6. Download the PDF

Browser-based, no upload, handles all common formats.

Supported input formats

The converter accepts:

  • JPG / JPEG
  • PNG
  • WebP
  • HEIC (iPhone photos)
  • GIF (first frame only, no animation)
  • BMP

For other formats (TIFF, AVIF, RAW): convert to a common format first using our image converters, then to PDF.

Multiple images into one PDF

For a multi-image PDF:

  1. Drop all images in at once
  2. Drag thumbnails to reorder
  3. Convert — all images become pages in one PDF

The order in the converter is the order in the PDF.

Layout options

Most converters offer:

One image per page (default): each image fills a page. Good for documents, photo portfolios.

Multiple images per page: 2-up, 4-up, 6-up — fits several images on each PDF page. Good for handouts or contact sheets.

Fit options:

  • Fit to page: image scales to maximum size within page boundaries
  • Original size: image at its native dimensions (may not fill page or may exceed)
  • Stretch to fill: image stretches to entire page (may distort)

For most uses: one image per page, fit to page.

Page size and orientation

Letter (8.5×11 inches): US standard. Default for most uses.

A4 (210×297mm): International standard. Use for international audiences.

Square: for image-heavy content where standard paper proportions look awkward.

Custom: specify exact dimensions.

Orientation: portrait (default) or landscape. Match to your images’ aspect ratio for best appearance.

Common scenarios

Receipts for expense reports: photograph receipts → convert to PDF → email or upload.

Scanned documents: phone scan → multiple JPGs → combine as PDF for sharing.

Photo portfolios: best images → PDF with one per page → email or print.

Product catalogs: product photos → multi-image PDF.

Application forms: filled paper forms photographed → PDF for online submission.

Manuscripts: handwritten pages photographed → bundled as PDF.

Documentation of physical objects: items, damage reports, before-and-after photos.

Image preparation tips

Before converting:

Rotate: ensure images are right-side-up — see Fix Sideways Image.

Crop: tighten on relevant content — see Image Cropper.

Adjust contrast: especially for scanned documents — see Photo Look Like Document Scan.

Resize if too large: original 4K phone photos make huge PDFs — see Reduce Photo Resolution.

Strip metadata if sharing publicly: EXIF Stripper.

On phone

iPhone:

  • Photos app: select multiple → Share → Print → pinch out → Share → Save to Files
  • See Combine PDFs on Phone for full mobile workflow

Android:

  • Google Drive: + → Scan → multi-image PDF
  • Or use our browser-based tool from mobile browser

What gets preserved

Preserved:

  • Image content
  • Colors
  • Resolution (up to PDF page size limits)

Affected:

  • Aspect ratios (may be cropped or padded depending on fit setting)
  • EXIF metadata (usually stripped from embedded images)
  • Transparency in PNGs (PDFs typically default to white background)

File size considerations

PDF size depends on:

  • Number of images
  • Image dimensions/resolution
  • PDF compression settings

Typical sizes:

  • 10 photo pages at full resolution: 10-30 MB
  • 10 compressed pages: 2-5 MB
  • 1 scanned document page: 200 KB - 2 MB

For email-friendly PDFs: compress with PDF Compressor after.

When PDF isn’t the right format

For some scenarios, alternatives may be better:

For web sharing: an image gallery (multiple images displayed inline) often beats a PDF.

For editing: keep images as separate files; PDF is harder to edit.

For social media: most platforms accept individual images directly; PDFs require download.

For printing single photos: photo print services usually want JPG/PNG directly.

PDF makes sense when bundling multiple images as a coherent document.

After converting

Privacy

JPG to PDF runs locally:

  • Images read with File API
  • PDF generated with pdf-lib in browser
  • No upload

For sensitive content (receipts with financial info, photos of identification, etc.), this matters.

TL;DR

  • Image to PDF: JPG to PDF (handles JPG, PNG, WebP, HEIC)
  • Multiple images: drag in all at once, drag-reorder, convert
  • Layout: one per page (default) or multi-up
  • Page size: Letter (US) or A4 (international)
  • For mobile: iOS Photos → Print → pinch out → Save to Files
  • After: PDF Compressor for email, PDF Merger for combining
