How to Merge Multiple Images into One PDF

Need to send 30 receipts to accounting, or submit a multi-page assignment as a single file? Merging images into one PDF is the cleanest solution.

The problem with sending loose images

• Email clients reorder or compress attachments unpredictably.
• Recipients must open files one by one.
• No guaranteed page order.

Merge images in 4 steps

1. Open ImgToPDF.online and upload all your images at once (multi-select works).
2. Drag the thumbnails into the exact order you want — or sort by name automatically.
3. Keep the default mode: "Merge all images into one PDF".
4. Convert and download a single, ordered PDF.

Useful options while merging

• Start page number — useful when the PDF continues an existing document.
• Watermark — stamp "CONFIDENTIAL" or your brand across pages.
• Mixed formats welcome — combine JPG, PNG and WebP in the same PDF.
