How to Convert JPG Photos to a PDF (One File, Right Page Size)

By the DocEpic team · Updated 10 November 2026 · 3 min read

Photos are how most documents start life today: a picture of an Aadhaar card, a mark sheet on the table, a bill from a shop. But forms, offices and email attachments want a PDF. Converting is simple, and with a few choices — page size, orientation, margins — the PDF looks like a proper scan instead of a phone gallery. Here is how.

Convert your photos

JPG to PDF turns JPG, PNG and WebP images into PDF pages, in the order you choose, and keeps phone photos the right way up.

1. Open JPG to PDF and add your photos. You can add many at once.
2. Drag them into the order the pages should appear.
3. Choose the page size: A4 for Indian forms and printing, US Letter for American forms, or Same as image to keep each photo's own size.
4. Choose the orientation — Auto picks portrait or landscape for each photo — and the margin around the picture.
5. Convert and download one PDF. To get a separate PDF for every image instead, tick One PDF per image.

The conversion runs in your browser: your photos are never uploaded.

Which page size should you pick?

A4 is the standard paper size in India and most of the world, and the safest choice for anything that may be printed or uploaded to a government portal. Same as image makes each page exactly the size of the photo — useful for a single screenshot or a receipt, but the pages of a multi-page PDF then have different sizes, which looks odd when printed.

A small margin makes a photographed document look like a scan and leaves room for printers that can't print to the edge. Choose no margin for photos you want to fill the page.

Make the photos look like a scan

Photos of paper often have a shadow, a dark table around the page, or a yellowish tint. For documents, Scan to PDF is the better route: it uses your phone camera and saves the pages in grey or black and white, which looks cleaner and gives a much smaller file. Use JPG to PDF for photos you already have.

iPhone photos in HEIC

iPhones save photos as HEIC by default. If your photos are HEIC files, convert them with HEIC to JPG first, then add the JPGs here. Photos shared from the iPhone's Photos app to a website are often converted to JPG automatically, so try adding them directly first.

If the PDF is too large

Each phone photo is 2 to 5 MB, so ten photos can make a 30 MB PDF — far over most upload limits. Compress the result with Compress PDF, or with Compress PDF to KB if the form names a size such as 200 KB.
