Many forms ask for one PDF, but your documents are photos on your phone: a marksheet, an Aadhaar card front and back, or signed pages. This JPG to PDF converter puts those images into a single PDF, in your browser, without uploading them.
How to convert JPG to PDF
- Add your images. You can add several JPG or PNG files at once.
- Put them in order with the up and down buttons. Each image becomes one page, from top to bottom. Remove any image you don’t need.
- Choose the page size: A4, Letter, or Fit to image, where each page is exactly the size of its image.
- Choose the orientation: Auto, Portrait or Landscape.
- Choose the margin: None or Small.
- Download the single PDF.
Choosing a page size
| Page size | Dimensions | When to use it |
|---|---|---|
| A4 | 210 × 297 mm | Standard paper in India and most countries; best for forms and printing |
| Letter | 8.5 × 11 in (215.9 × 279.4 mm) | Standard in the USA and Canada |
| Fit to image | Same as each image | Screen viewing, posters, screenshots, no white borders |
With A4 or Letter, each image is scaled to fit inside the page without being stretched, so a little white space may remain on two sides. With Fit to image, there is no white space, but pages can be different sizes if your images are.
Orientation and margins
- Auto suits most jobs: a tall photo goes on a portrait page and a wide one on a landscape page.
- Portrait or Landscape forces every page the same way, which is neater when you will print the file.
- A Small margin keeps content away from the paper edge, where many printers can’t print. Choose None for on-screen reading.
Tip: For scanned documents, take the photo straight on, in good light, and crop it tightly on your phone before adding it. The PDF can only be as clear as the pictures you put in.
Keeping the PDF small
A PDF made from images is roughly as big as the images inside it. Phone photos can be several megabytes each, so a ten-page file can easily exceed the upload limit of a job or exam portal. Shrink the photos first with the image compressor or the image resizer; a width of around 1600 pixels is still very readable for an A4 page.
JPG suits photos and scans because it uses lossy compression; PNG is lossless and can be much larger for photos. The MDN image format guide compares them. PDF itself is an open ISO standard, described in the Library of Congress format notes, which is why a PDF opens the same way on almost any device.

Frequently asked questions
Are my images uploaded to make the JPG to PDF file?
No. The PDF is built inside your browser and saved straight to your device. Your photos stay with you.
Can I add PNG screenshots as well as JPGs?
Yes. You can mix JPG and PNG images in the same PDF.
How do I change the page order?
Use the up and down buttons next to each image. The order in the list is the order of the pages.
Will the text in my scanned images be searchable?
No. Each page is an image, so the PDF looks like your scans but the words can’t be selected or searched. That needs OCR (text recognition), which this tool doesn’t do.
