How This Tool Builds Your PDF
Add JPG, JPEG, or PNG images and the tool validates each one, prepares a preview, and lists them in the order selected — that list becomes the page sequence in the final PDF. If page two ends up before page one, the PDF will reflect that, so use the preview list as your checkpoint before creating the file. Removing an image from the list updates the sequence immediately.
Page orientation controls the canvas used for every page. Portrait suits vertical documents, receipts, letters, and phone scans. Landscape suits wide screenshots, horizontal certificates, spreadsheets, and presentation-style images. Pick one orientation for the whole set so the PDF reads consistently rather than mixing pages that feel accidental.
Margin controls how each image sits on the page. No margin scales the image to fill as much of the page as possible while keeping its aspect ratio — useful when the image should occupy the maximum available space. A small margin is 8 mm, the default; a large margin is 16 mm. All pages use A4. More whitespace can help for printing or annotation.
Every image is scaled proportionally to fit the selected page area without stretching: a square photo stays square, a tall document stays tall. The tool compares the image's aspect ratio against the usable page area after margins are applied, picks the largest width or height that fits, and centers the result — so alignment stays predictable even when source images have different dimensions.
For the cleanest result, crop away distracting edges, rotate sideways photos before adding them, and avoid mixing unrelated documents into one PDF. If a form or portal expects a specific document order, build the PDF in that order so the reviewer does not have to search for anything.
