Methods Compared

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

1. Open sakutto's JPG to PDF converter
2. Drag and drop multiple images or use "Choose File" to add them
3. Drag to rearrange the page order
4. Set paper size (A4, Letter, etc.), orientation, and margins
5. 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

1. Open the Photos app and tap "Select" in the top right
2. Tap the photos you want in the order you want them
3. Tap the Share button (square with arrow)
4. Select "Print"
5. On the preview screen, pinch outward (spread two fingers) to reveal the PDF
6. Tap the Share button again and choose "Save to Files"

Using the Files App (iOS 16+)

1. Place all images in the same folder in the Files app
2. Tap "..." → "Select" and choose the images
3. 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

1. Open sakutto's tool in Chrome or your preferred browser
2. Tap "Choose File" and select multiple images
3. Adjust page order and paper settings, then tap "Create PDF"
4. The downloaded PDF is saved in your Downloads folder

Method 4: Desktop (Windows / Mac)

Windows: Microsoft Print to PDF

1. Select all images you want to combine (Ctrl+click)
2. Right-click → "Print"
3. Choose "Microsoft Print to PDF" as the printer
4. Set paper size and quality, then click "Print"
5. Choose a save location for the PDF

Files are sorted alphabetically, so use numbered file names to control the order.

Mac: Preview.app

1. Open the first image in Preview
2. Go to View → "Thumbnails" to show the sidebar
3. Drag and drop remaining images into the thumbnail area
4. 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
