How to Convert Images to PDF

Why put images into a PDF?

• Submission portals that accept only one file: combine every page of your application into a single PDF.
• Photos of whiteboards, notes or artwork that must be shared as one document.
• Print shops that expect a paginated document rather than a folder of images.
• Archiving: a PDF keeps your pages in a fixed order on every device, while loose JPEGs get shuffled and renamed.
• Contracts photographed page by page that need to travel as one file.

The conversion places each image on its own page, scaled to fit with a margin, and writes a standard PDF anyone can open. What you see when you open the result is exactly what prints.

Choose A4 or Letter first

Match whatever the receiving institution specifies; when nothing is specified, A4 is the international default. The size is set when the PDF is created, so choose it before you convert rather than resizing afterwards.

Convert images to PDF step by step

1. Open the converter

   Load the Image to PDF tool and select your images. You can add several at once; repeated selections of the same file are skipped automatically.

2. Check the order

   Pages appear in the order the images were added. If page two and three are swapped, clear the list and re-add them in the right sequence.

3. Pick the page size

   Choose A4 or US Letter to match the destination's requirements.

4. Convert and download

   Press convert and save the PDF. Each image is centred on its page with a white margin, so mixed photo sizes still look like one document.

Photographing a stack of paper documents? The Document Scanner to PDF is built for exactly that: it turns a sequence of phone photos into one multi-page PDF.

Common mistakes to avoid

• Ignoring image orientation. Rotate sideways photos first — they will sit sideways on the page afterwards (How to rotate PDF pages online fixes the result).
• Feeding enormous camera originals. A 12-megapixel photo per page adds up fast; downsize the images first if the document must stay small.
• Assuming the PDF contains real text. Pages produced from images are pictures of text — they cannot be selected, searched or copied. When a submission requires searchable text, run the document through an OCR step such as Image to Text as well.
• Wrong page size for the destination. Re-read the instruction email: some portals reject Letter files outright.
• Forgetting to compress before upload. If the portal has a size limit, finish with the PDF Compressor.

The short version

Add your images in order, choose A4 or Letter, convert, and verify. The result is a single, portable, consistently paginated document — accepted by the portals that only take one file, and ready to print on any device.
