Choose the method that fits your device and situation.
Method 1: Use an Online Tool (Recommended)
The most versatile option — works on any device with a browser.
Steps
- Open sakutto's JPG to PDF converter
- Drag and drop multiple images or use "Choose File" to add them
- Drag to rearrange the page order
- Set paper size (A4, Letter, etc.), orientation, and margins
- Click "Create PDF" and download
Supports JPG, JPEG, PNG, and WebP formats with batch file selection.
Tips for Page Order and Paper Settings
- Number your files: Naming files "01_cover.jpg", "02_contents.jpg" ensures consistent ordering
- Mixed orientations: If images have different orientations, choose "Auto" for the best fit
- For document submission: Use "Medium" margins or larger to prevent edges from being cut off during printing
Method 2: iPhone / iPad
iPhone's built-in features can combine photos into a PDF without any apps.
Using the Photos App
- Open the Photos app and tap "Select" in the top right
- Tap the photos you want in the order you want them
- Tap the Share button (square with arrow)
- Select "Print"
- On the preview screen, pinch outward (spread two fingers) to reveal the PDF
- Tap the Share button again and choose "Save to Files"
Using the Files App (iOS 16+)
- Place all images in the same folder in the Files app
- Tap "..." → "Select" and choose the images
- Tap "..." in the bottom right → "Create PDF"
Files are sorted by name, so numbered file names produce predictable results.
Method 3: Android
Android doesn't have a built-in image-to-PDF combiner, so using a browser-based online tool is the easiest approach.
Using sakutto in the Browser
- Open sakutto's tool in Chrome or your preferred browser
- Tap "Choose File" and select multiple images
- Adjust page order and paper settings, then tap "Create PDF"
- The downloaded PDF is saved in your Downloads folder
Method 4: Desktop (Windows / Mac)
Windows: Microsoft Print to PDF
- Select all images you want to combine (Ctrl+click)
- Right-click → "Print"
- Choose "Microsoft Print to PDF" as the printer
- Set paper size and quality, then click "Print"
- Choose a save location for the PDF
Files are sorted alphabetically, so use numbered file names to control the order.
Mac: Preview.app
- Open the first image in Preview
- Go to View → "Thumbnails" to show the sidebar
- Drag and drop remaining images into the thumbnail area
- Go to File → "Export as PDF" to save
Drag thumbnails to rearrange page order.
Tips for Clean Results
- Match image orientations: Mixing portrait and landscape creates inconsistent page sizes. Group similar orientations together
- Check resolution: For printing, 300 dpi or higher is ideal. For screen viewing, 150 dpi is sufficient
- Remove unwanted images first: Easier than deleting pages from the finished PDF
- Watch file size: Many high-resolution images can create PDFs of tens of megabytes. Use sakutto's PDF compression tool to reduce size before emailing
