How to convert images to PDF, step by step
Step 1: Open the tool and choose your images
Open the Image to PDF page. Tap Choose images to pick photos from your gallery, or Take photo to use your camera. On a computer you can also drag images onto the box.

Step 2: Arrange the pages
Your photos appear as pages. Drag a thumbnail to change the order. Use the ⟳ button to rotate a photo and ✕ to remove it. Need more photos? Tap + Add more. Clear all starts again.

Step 3: Choose page size, margin and quality
- Page size: “Same as image” keeps each photo’s shape. Choose A4 or Letter if you will print the PDF or upload it to a form.
- Margin: adds a white border around each photo. The thumbnails update right away, so you see the result before you make the PDF.
- Quality: HD for the sharpest result, Normal for everyday use, Small file when the PDF must be small for WhatsApp or email.
- File name: type a name for your PDF.
Step 4: Generate the PDF and download it
Tap Generate PDF. When it is ready you will see “Your file is ready” with the file name and size. Tap Download PDF to save it to your phone or computer.

Useful tips
- Sending on WhatsApp or email? Choose Small file. If the PDF is still too big, use Compress PDF.
- Printing, or uploading to a government or college form? Choose A4 with a small margin.
- Scanning paper documents with your camera? Scan to PDF is made for that.
- Already have several PDFs? Join them with Merge PDF.
Are my photos safe?
Yes. The PDF is made inside your own browser. Your photos are not sent to any server, so nobody else can see them. The tool keeps them only in this browser on your device, so a page refresh does not lose your work; tap Clear all to remove them.
