How to Convert JPG to PDF Free Online

Why convert JPG to PDF?

Photos and scanned images saved as JPGs are fine for sharing informally, but many official processes — job applications, tax submissions, university applications, visa documents — require PDF format. PDF preserves the image quality and layout exactly regardless of what device opens it. It is also easier to combine multiple JPG scans into one organised PDF document than to send a folder of image files.

Convert JPG to PDF — step by step

Converting a single JPG or multiple JPGs into one PDF takes under 30 seconds.

1. 1Go to the Image to PDF tool.
2. 2Upload one or more JPG files. You can also upload PNG, WebP, or BMP files.
3. 3Arrange them in the order you want them to appear in the PDF.
4. 4Choose page size (A4 is the default) and orientation.
5. 5Click Convert and download the PDF.

Converting multiple JPGs into one PDF

When you upload multiple JPG files, each image becomes one page in the resulting PDF. This is ideal for scanned multi-page documents — scan each page separately, upload all the scans, arrange them in order, and download as a single multi-page PDF. The original image quality is preserved and the output looks exactly like a properly scanned document.

Page size and margins

By default, the tool fits each image to an A4 page. If your image is wider than it is tall (landscape), the tool automatically uses landscape orientation. For images that are not standard document proportions — a photo of a business card or a wide diagram — you can choose to fit the image to the page with margins, or stretch it to fill the page completely. Fitting with margins looks more professional for document use.

JPG vs PNG — does it matter for PDF conversion?

For most document scanning purposes, JPG is fine — it is smaller and fast to upload. PNG is better when the image contains text, diagrams, or screenshots because PNG is lossless and text stays sharp. Both formats convert to PDF identically using this tool. If you are converting a photo, JPG is perfectly fine. If you are converting a screenshot or a document scan where text sharpness matters, PNG gives a slightly cleaner result.

Converting phone photos to PDF

If you have taken photos of documents with your phone, these are typically JPG files in your camera roll. Transfer them to your computer or use the tool directly from your phone browser. Upload the photos, reorder them if needed, and download the PDF. This is the fastest way to submit a photographed document when a PDF is required.
