Why combine JPGs into a PDF

One attachment instead of many

Much easier to share via email or upload to official portals than 10+ loose images.

Pages stay in order

A PDF permanently locks in the sequence you choose; loose image files often sort unpredictably on different phones.

Same look everywhere

PDFs render identically across Windows, Mac, iOS, Android, and Linux.

Standard printing sizes

Embedded images fit standard A4 or US Letter sheets without awkward scaling issues.

Combine JPG to PDF Now

On Windows

Easiest

PDFteq in your browser

Chrome, Edge, or Firefox — upload, arrange, convert, download. Safe and private.

Built-in

Windows "Print to PDF"

Select your JPGs in File Explorer → right-click → Print → set printer to "Microsoft Print to PDF" → Print.

⚠️ Limitation Windows arranges files alphabetically or based on file timestamps, giving little control over sequence. It also re-compresses photos, which can introduce compression artifacts.

On Mac (macOS)

Built-in (Best)

Apple Preview App

Open the first image in Preview → Click View → Thumbnails → drag and drop additional JPGs into the sidebar → drag thumbnails up/down to reorder → File → Export as PDF.

Quick Offline

Finder Quick Actions

Select all images in Finder → right-click → Quick Actions → Create PDF. Instant, though it locks to default aspect ratios without margins.

On iPhone & Android

📱 Mobile Browser Workflow (No App Needed)

iPhone / iPad: Open Safari → visit PDFteq → tap select → choose from Photo Library or Files app → Convert → Save to Files.

Android: Open Chrome → visit PDFteq → choose images from Gallery / Google Photos → Convert. Download lands straight in your Downloads folder.

Keeping image quality intact

Most basic converters re-compress images during compilation. PDFteq embeds JPEG files directly into the PDF container without modifying the JPEG byte stream — ensuring zero loss of original detail.

Common mistakes to avoid

  • 1. Not reviewing page order: Always verify your selection sequence before hitting convert.
  • 2. Wrong page dimensions: Mixing wide landscape photos with portrait documents without selecting "Fit-to-Image" can create awkward white bars.
  • 3. Ignoring phone photo orientation: Because modern mobile cameras store orientation in EXIF tags (which standard PDF libraries don't always interpret), make sure your photos are rotated correctly in your gallery first.
