Steps to combine images into one PDF
- Drop your images in the box above (JPG, PNG, WebP, AVIF, GIF, BMP, SVG and iPhone HEIC are supported).
- Page order follows the list; use the sort menu to order by name or size.
- In the Output section choose the page size: A4 (centred) for documents and printing, or Match the image so each page has the image’s own proportions.
- Start the conversion, then press “Download single PDF”.
A4 or image-sized?
With A4 each image is fitted inside the page with a 24 pt margin and centred; landscape images get a landscape page. With image-sized pages each page has exactly the image’s proportions and no margin. For scans, receipts and photo albums A4 usually looks tidier.
Keeping the file small
Phone photos are large, so a merged PDF can quickly reach tens of megabytes. If an email or application form has a limit, use the “Small file (1600 px)” button: images are reduced to a sensible resolution and quality drops to 72%. Images are embedded as JPEG; no text recognition (OCR) is done, so text in the PDF cannot be selected.
If your iPhone photos are HEIC you do not need to convert them first; add them directly. See the HEIC guide for details.
