JPG to PDF — combine photos into one PDF, no upload

How to use JPG to PDF

1. Add one or more images. JPG, PNG, WebP, GIF, BMP and AVIF are accepted.
2. Drag the images into page order.
3. Choose a Page size: A4, US Letter, US Legal, A3, A5, or Same as each image so each page matches its picture exactly.
4. Choose an Orientation (Auto, Portrait or Landscape) and a Margin in millimetres (10 mm by default).
5. Press Create PDF and download the file.

What it does and when to use it

Photographing a document with your phone is quick, but many institutions want a PDF, not a set of photos. This tool turns those photos into one tidy document: a multi-page form photographed page by page, receipts for an expense claim, ID card front and back, handwritten notes, a signed letter, or pictures for a portfolio.

Each image goes on its own page, scaled to fit inside the margins without being stretched or cropped. With A4 or Letter you get a document that prints properly on standard paper. With Same as each image, every page is exactly the size of its picture, which suits photo collections and screenshots.

How it works

Everything runs in your browser using pdf-lib. JPG files are embedded byte for byte, so there is no second round of compression and no loss of quality. PNG files are embedded losslessly. Images in other formats are first converted to JPEG in the browser, and the result tells you how many were converted.

For JPG photos the tool reads the EXIF orientation tag that phones write and rotates the image so it appears upright. In Auto orientation, each page is portrait or landscape to match the shape of its image, which wastes the least space. The image is then centred inside the margin you set.

Because JPGs are copied rather than re-encoded, the PDF is roughly as large as all your photos together. The result shows the total size so you can check it against any upload limit.

Worked examples

Five phone photos of a document. Choose A4, Auto orientation and 10 mm margins. You get a five-page A4 PDF with each photo upright and fitted inside the margins. If it is too large for a form, follow up with Compress PDF to 1 MB or a smaller size.

ID card front and back for a form. Add both photos, choose A4, and you get a two-page PDF. If the form wants both sides on one page, first combine the photos with the Image Collage tool, then convert the single image.

Screenshots for a bug report. Choose Same as each image with a margin of 0, so each page is exactly the screenshot with no white border.

Limits and tips

• Pages are pictures, so text in them cannot be selected until you run OCR.
• Crop photos before converting for a cleaner document; the Image Cropper works on your device too.
• Large photos make large PDFs. Resizing images first with the Image Resizer, or compressing the finished PDF, keeps the file manageable.
• The reverse job, getting pages out of a PDF as images, is handled by PDF to JPG. For screenshots and graphics with sharp edges, PNG to PDF does the same with PNG files.
