JPG and PDF: what each format is for
A JPG holds one picture. A PDF holds pages, and each page can carry text, pictures or both. That's why forms, job portals and offices usually want a PDF: a ten-page application is one tidy file instead of ten loose photos.
Converting doesn't turn your photo into editable text. Each image becomes a page with that picture on it, just as if you had printed it.
| JPG | ||
|---|---|---|
| Created by | Joint Photographic Experts Group, 1992 | Adobe, 1993 (an ISO standard since 2008) |
| Holds | A single image | Any number of pages |
| Page size | None, just pixels | Fixed, such as A4 or US Letter |
| Prints at the right size | Depends on the app | Yes, page size is built in |
| Accepted by forms and portals | Sometimes | Almost always for documents |
| Best for | Sharing a single photo | Multi-page documents, applications, records |
What each setting does
- Page size. A4 (210 × 297 mm) is the standard in India, Europe and most of the world. US Letter (8.5 × 11 in) is the norm in the US and Canada. Same as image makes each page exactly the size of its picture, with no white border.
- Orientation. Automatic picks portrait or landscape to suit the shape of each image. Choose Portrait or Landscape to force every page the same way.
- Margin. None fills the page edge to edge. Small (the default) leaves a thin white border that most printers need. Large gives a wide border, useful if pages will be hole-punched or bound.
- Output. One PDF combines every image into a single document. One PDF per image gives you a separate PDF for each picture.
Scanning documents with your phone for an application
Many forms ask for certificates, ID proofs or receipts as a single PDF. A phone photo works well if you take a little care:
- Lay the page flat in good light and shoot straight down, so the page fills the frame.
- Crop each photo in your phone's gallery before adding it here. Cropping is the easiest way to get clean A4 pages.
- Add the photos in page order, or fix the order with the arrows before you click Combine.
- If the portal wants A4, set Page size to A4. Your photo is placed on a proper A4 page.
Keeping the PDF small
The size of the PDF mostly comes from the images inside it. Ten 4 MB phone photos make a PDF of roughly 40 MB. There's no compression setting here, so if a form has a strict limit such as 100 KB or 1 MB, make the images smaller before you combine them.
Phone photos are far bigger than a document needs. Resize them in your phone's photo editor, or send them to yourself with a smaller size option, then build the PDF. Screenshots saved as PNG can be much larger than JPGs; converting those PNGs to JPG first with the Smallest file quality often shrinks them a lot.
Built-in alternatives on your device
Windows 10 and 11: select the images in File Explorer, right-click, choose Print, and pick Microsoft Print to PDF as the printer.
Mac: open the images in Preview, select them all in the sidebar, then choose File → Print and Save as PDF.
iPhone and iPad: in the Files app, select the images, tap the More button and choose Create PDF.
These work, but they give you less control over page size, margins and order. This page behaves the same on every device, including Android phones and Chromebooks.
Limits worth knowing
- The PDF contains pictures of your pages, not searchable text. You can't select or copy words from it.
- Images aren't enhanced or upscaled. A blurry photo stays blurry on the page.
- There's no limit on how many images you add, but a very large batch of full-size photos needs plenty of memory. On an older phone, combine in smaller groups and join the resulting PDFs afterwards.
- Got iPhone photos in HEIC format? Turn them into JPGs first, then add them here.
Frequently asked questions
How do I combine multiple JPGs into one PDF?
Add all the images, put them in order with the up and down arrows, leave Output set to One PDF and click Combine. You get a single PDF with one image per page.
Are my images uploaded anywhere?
No. The PDF is built on your device, inside your browser, and your images are never uploaded. The page itself loads its code, ads and cookieless analytics like any website, but your files stay put. See how to check this yourself.
How do I make the PDF A4 size?
Choose A4 under Page size before you click Combine. Each image is placed on a 210 × 297 mm page. Pick a margin if your printer can't print to the edge.
Can I make a JPG to PDF under 100 KB?
Only if the images are small to begin with, because the PDF is about as big as the images inside it. There's no compression option here, so shrink or resize the photos first, then combine them. One clear page at a modest resolution can fit; several full-size phone photos won't.
Can I convert PNG, JPEG and WebP images together?
Yes. JPG, JPEG, JFIF, PNG and WebP images can be mixed in the same PDF. JPEG and JPG are the same format with a different extension.
Can I change the page order?
Yes, before you combine. Each row has up and down arrows; the order of the list is the order of the pages. To change it afterwards, click Convert more and add the images again.
Does it work on my phone?
Yes. It runs in the browser on Android, iPhone and iPad, with nothing to install. Tap Choose JPG files and pick photos from your gallery.
Is my photos' location data stored in the PDF?
JPGs go into the PDF without re-compression, so by default (Metadata: Keep) their EXIF data, which can include GPS location, comes along inside the PDF. Set Metadata to Remove to strip EXIF and XMP from each photo and leave the PDF without document information.
