Under the hood

How it works — and where its limits are

Photographs of paperwork are how a lot of documents start life now: a phone picture of a signed page, a scan saved as PNG, a screenshot of a receipt. Image to PDF wraps those pictures into a single, portable document that email systems, application portals and colleagues’ devices all accept predictably. This tool embeds each JPG or PNG into its own page of a new PDF with pdf-lib — the image data is embedded as-is, not re-rendered, so the picture in the PDF is the picture you supplied.

The two page-size choices. With A4 pages, every page of the result is a standard A4 sheet (595.28 × 841.89 points) and each image is scaled to fit inside it with a margin, keeping its aspect ratio and centred — nothing is cropped and nothing is stretched. That is the right choice for printing and for portals that expect uniform documents, and it mixes portrait and landscape photos gracefully, each fitted within the same portrait sheet. With image size, each page takes the dimensions of its image (pixels converted at 96 DPI, so one pixel becomes 0.75 points), which preserves the image’s own proportions page by page — better when the PDF is a faithful container for the pictures themselves rather than a printable document.

Order is the content. In a combined document, sequence carries meaning: the front of the ID before the back, the signed page after the terms. The list order is the page order, and the numbering on each row is the final position. Drag rows or use the arrows before building; if you build in the wrong order, your image files are untouched, so just reorder and build again.

What this tool does not do. It does not run OCR — the pages in the result are pictures, not searchable text. It does not enhance, straighten or compress your images beyond embedding them; a blurry photo makes a blurry PDF page. If file size matters, compress the finished PDF with our Compress tool, which knows how to re-encode embedded images. Very large phone photos are embedded at full fidelity, which is honest but can make a heavy PDF — again, the Compress tool is the follow-up step.

Local by design. Photos of identity documents and contracts are exactly the files that should not tour the internet for a simple conversion. Here they never leave your device: the PDF is assembled in this tab, and the site keeps no record of your images’ names or sizes.

FAQ

Frequently asked questions

JPG and PNG. Other formats (such as WebP or HEIC from phone cameras) need converting to JPG or PNG first — most phones can do that from the share sheet or a photo editor. Files that are not JPG or PNG are skipped with a note, never silently.

A4 gives every page the same standard sheet size with each image fitted inside, aspect ratio kept and centred — best for printing and formal submissions. Image size makes each page match its own picture’s proportions — best when the PDF is simply a container for the images.

No. The pages are embedded pictures; there is no OCR in this tool. If you need searchable text, the images would have to go through an OCR process, which this local toolbox deliberately does not offer.

Images are embedded at full fidelity, and modern phone photos are multi-megabyte files. Run the result through our Compress tool afterwards — its image re-encoding pass is designed for exactly this case.

No. The PDF is assembled in your browser with pdf-lib. Your images never leave your device, and no image names or sizes are reported anywhere.
