Why photos become PDFs
A loose collection of photos is hard to share properly: messaging apps compress them, email clients scatter them out of order, and nobody wants to open twelve attachments to read one form. A PDF solves all of that at once — one file, pages in order, printable as-is, and readable on any device.
The usual cases: photographing receipts for expense reports, capturing multi-page forms when no scanner is around, bundling a child's homework photos for a teacher, or collecting screenshots and reference images into a single document to keep.
How to convert images to PDF with ThePDFBuddy
- Open the Images to PDF tool. Go to the Images to PDF page and drop your JPG or PNG files onto the workspace, or tap to browse and select them.
- Check the order. The first image you add becomes page 1, the second becomes page 2, and so on. Remove anything that does not belong before you build.
- Choose a page size. Fit each image makes every page match its image exactly — best for mixed photo collections. A4 or US Letter gives every page a uniform, print-friendly size, with your chosen margin around the image.
- Click "Create PDF". The tool builds your PDF on your device, one page per image. The result downloads as images.pdf — rename it to something descriptive, like receipts-march.pdf.
Choosing the right page size
- Fit each image: no resizing, no margins — each page matches its photo. Ideal for portfolios, photo collections, and mixed portrait/landscape sets.
- A4: the international standard. Choose this when the PDF will be printed or filed formally.
- US Letter: the North American standard, for documents aimed at US recipients.
- Margins: none keeps the image edge-to-edge; small and wide margins give a cleaner, more document-like frame — especially useful with A4 or Letter.
Pitfalls to watch for
- Wrong order. The most common mistake. Review the file list before clicking Create PDF — once built, you cannot reorder pages without rebuilding.
- Upside-down or sideways photos. The tool places images as they are. Rotate any wayward photos in your phone's gallery app before adding them.
- Unsupported formats. The tool accepts JPG and PNG only. GIFs, BMPs, WebP files, and iPhone HEIC photos need converting to JPG or PNG first (most gallery apps can export as JPG).
- Huge photos, huge PDF. Full-resolution camera photos make large PDFs. If the result is too big to share, run it through the Compress PDF tool afterward.

Image-to-PDF FAQs
Which image formats can I convert to PDF?
The tool accepts JPG (JPEG) and PNG files — the two formats phones and cameras produce most. Other formats like GIF, BMP, or HEIC need to be saved as JPG or PNG first.
How many images can I convert at once?
There is no fixed limit. Each image becomes one page, in the order you select them. For very large batches on older phones, working in smaller groups is more comfortable.
Will each image become its own page?
Yes — one image, one page. You choose whether each page fits its image exactly or uses a standard A4 or US Letter page with your chosen margin.
Can I mix portrait and landscape photos in one PDF?
Yes. With "Fit each image", every page matches its own image's dimensions and orientation, so portrait and landscape photos sit together without distortion.
