How to Convert JPG to PDF Online for Free (Photos and Scans)

Photos of documents are easy to take and awkward to send. A bank, a college or a government portal often wants a PDF, not a pile of pictures. The JPG to PDF Converter turns one image, or many, into a single PDF file in your browser. This guide shows how to use it, how to choose the page size and margins, and how to keep the file small enough to upload.

Convert JPG to PDF in four steps

1. Open the JPG to PDF Converter.
2. Drop one or more images on the upload box, or tap it to choose them. JPG, PNG and WebP are accepted.
3. Check the thumbnails. Use the arrows to change the order and the bin button to remove an image. Then choose the page size, orientation and margin.
4. Press Create PDF, then Download PDF. The file is saved as images.pdf.

Each image becomes one page, in the order shown. The conversion happens on your device, so photos of ID cards, certificates or bills are not uploaded anywhere.

Choose the right page size

The tool offers three choices.

With A4 or Letter, each image is scaled to fit inside the page and its margin, keeping its proportions, and centred. Nothing is stretched. Because the picture is scaled to fill the page, a very small image is enlarged and can look soft, so start from a photo with plenty of pixels. With Same as the image, the page is as large as the picture plus the margin you choose.

Orientation and margins

Orientation can be Automatic, Portrait or Landscape. Automatic puts wide images on landscape pages and tall images on portrait pages, so a mix of phone photos and sideways screenshots each get a sensible page. Orientation is not used when you choose Same as the image.

Margin is the white border around the picture:

• None: the picture reaches the edge of the page.
• Small: about 7 mm.
• Medium: about 14 mm.
• Large: about 25 mm, one inch.

For a document that may be printed, Small or Medium keeps text away from the edge. For a photo, None looks best.

What happens to your image quality

JPG and PNG images are placed into the PDF as they are, so the conversion adds no extra loss of quality. WebP images cannot be stored in a PDF directly, so the tool first converts them to PNG, which is lossless. The page then shows the image at the size that fits the page. What you see on the screen is what the PDF contains.

Photograph documents so the PDF looks good

The PDF can only be as clear as the photo. A few habits make a big difference:

• Place the paper flat on a plain surface and photograph it from directly above, so the edges are straight.
• Use even light. Avoid shadows from your hand or phone, and avoid glare on glossy paper.
• Fill the frame with the page, but keep all four edges in view.
• Take one photo per page and check that the text is readable when you zoom in.

When the PDF is too big

Large photos make large PDFs. A JPG photo of several megabytes adds roughly that much to the PDF, and ten of them can easily make a file too big to email. You have two good options:

1. Shrink the photos first with the Image Compressor, then convert. The guide to how to compress images explains the trade-off between size and quality.
2. Shrink the finished PDF with Compress PDF. Read its note first: it turns every page into a picture, so text in the compressed copy cannot be selected. Keep the original too.

Each image can be up to 25 MB. If a file is bigger, the tool tells you.

Combine and extend the result

• Add to an existing PDF. Convert your images, then join the result with other documents using Merge PDF. The guide on merging PDF files shows how.
• Go the other way. PDF to JPG turns the pages of a PDF back into pictures.
• Not sure which image format to use? See JPG vs PNG vs WebP.

Practical uses

• Scanned documents: turn phone photos of paper forms into one PDF.
• Receipts and expenses: collect receipt photos into a single file for a claim.
• Portfolios: put artwork or design screenshots into one shareable file.
• Application forms: convert a picture of a signed document into the PDF a portal requires.

Common mistakes to avoid

• Wrong order. Check the thumbnails before you create the PDF, because the order cannot be changed afterwards without making it again.
• Heavy photos. Compress before converting if the file must be small.
• Cropped edges. Leave a small margin around the paper when you photograph it, then use a Small margin in the tool.
• Assuming a PDF is searchable. A PDF made from photos holds pictures of text, not real text. This tool does not read the text in images.

Frequently asked questions

Can I convert several images into one PDF? Yes. Add them all, arrange the order and create one PDF with one image per page.
