Images to PDF: make the pages tell a clear sequence
Receipts and notebook pages are easy to photograph but awkward to follow as scattered attachments. PDF can turn them into a readable sequence. It does not automatically repair a missing photograph or turn the pictured writing into text.
Order the meaning before combining files
Put the cover before the detail, keep both sides of a document together, and check for duplicates or missing pages. Capture time and phone filenames do not always match reading order.
Correct orientation and crop irrelevant material in an appropriate copy beforehand when needed. Do not include a private photograph merely because it was adjacent to the intended set in your gallery.
Combining text pictures does not create actual text
Wrapping images of text in a PDF does not by itself make them searchable or copyable as text. Actual text requires recognition or a text source; that is a different job from combining images.
This path does not perform OCR. If the recipient needs searchable content or appropriate screen-reader access, retain a qualified text source or prepare a suitable version rather than describing the image bundle as a text document.

Check the complete page and its fine detail
Inspect the PDF’s page count, orientation and edges. Open a small number or word from every important photograph, not only the cover. Increasing display magnification cannot remove source blur.
Page dimensions may differ when source image dimensions differ. Combining here does not imply a uniform paper template or recovered document layout. Transparent images are also flattened against a background, so inspect artwork before sharing.
Example: a four-image visit summary
Your set contains a cover, two consecutive notes pages and a receipt, intended in order 1, 2, 3, 4. Accidentally adding the second notes page twice while omitting the receipt can still leave four pages. Count alone does not establish completeness.
Open all four pages and match their contents to the short checklist. Searching for a clearly pictured word may find nothing: that is a known limit of an image-only PDF without OCR, not evidence that page assembly failed.
