Quick answer: the easiest way to convert JPG to PDF on Android is Toolzio's free JPG to PDF tool in Chrome — add your photos, arrange them, tap Create PDF, and download the result. No app, no account, and your photos never leave your phone. If you would rather use nothing but what is already on the phone, Android's built-in Print to PDF does the same job from Gallery or Google Photos. Both are free; this guide covers all three ways, then helps you pick.

Method 1: convert in your browser (no app, no account)

  1. Open Chrome on your Android phone and go to the JPG to PDF tool.
  2. Tap to add images and pick your photos from Gallery or Files. JPG and PNG both work — screenshots included.
  3. Arrange the photos in the order you want them. The PDF keeps exactly this order, one photo per page.
  4. Pick a page size: Letter for US paperwork, A4 for anything going abroad, or Fit if nothing may be cropped.
  5. Tap Create PDF, then download the file (named images.pdf). It lands in your Downloads folder — open it once and flip through before sending.

This is the method to use when the order matters or you have several photos: it is the only one of the three that lets you reorder pages and set margins before converting. It also works the same on any Android phone, Samsung or Pixel, because it runs in the browser rather than in a manufacturer's app. Our general guide to converting JPG to PDF covers the page-size and orientation settings in more detail.

Method 2: Gallery's built-in Print to PDF

  1. Open the Gallery app and select the photo — or long-press to select several photos at once.
  2. Tap Share (or the three-dot menu) and choose Print.
  3. At the top, change the printer to Save as PDF.
  4. Set the paper size (Letter or A4) and check the preview — each selected photo becomes one page.
  5. Tap the PDF button to save. Pick a name and a folder if asked; otherwise it goes to Downloads.

This is the fastest method for a single photo, and it needs no internet at all. The trade-off is control: you cannot reorder pages after selecting them or set margins, so get the selection order right first. On Samsung phones this lives in the Gallery app; the menu names vary slightly by manufacturer, but Print and Save as PDF are there on all modern Android phones.

Method 3: Google Photos' Print to PDF

  1. Open Google Photos and select the photo (or several photos).
  2. Tap Share, then Print.
  3. Change the printer to Save as PDF, check the paper size and preview, then save.

This is the same built-in trick as Method 2, through Google's app instead of your manufacturer's Gallery — the natural path on Pixel phones, where Google Photos is the default gallery. If a photo is backed up to Google Photos but not stored on the phone, it downloads first; that is the only step that needs a connection.

One photo or many? Pick the right method

  • One photo, in a hurry: Print to PDF from Gallery or Google Photos — three taps and you are done.
  • Several photos in a set order: the browser tool — reorder with the arrows before converting, and set page size and margins. Our guide to making a PDF from multiple images covers the settings.
  • A scanned document or form: the browser tool with Fit page size, so nothing at the edges is cropped.
  • Sharing to email or WhatsApp: any method works, but check the file size first — photos straight from a modern phone camera make large PDFs. If it is too big to send, our guide to compressing a PDF without losing visible quality helps.

What converting can't do

  • It won't make the text searchable. The PDF holds pictures of your photos, not text — words in a photographed document cannot be selected, searched, or copied. Searchable text needs OCR, which none of these methods does.
  • It won't fix a bad photo. Cropping, rotating, or brightening has to happen in your photos app before you convert.
  • Print to PDF won't reorder pages. The pages follow the order you selected the photos in. If the order comes out wrong, convert again — or fix it afterwards with the Organize PDF tool.
  • It won't convert HEIF photos directly. Most Android phones save JPG, but if yours is set to HEIF, export the photo as JPG first.

Common mistakes

  • Forgetting to switch the printer to Save as PDF. Print defaults to a real printer if one is set up; the PDF option is in the printer dropdown at the top.
  • Sending the JPG instead of the PDF. After saving, attach the PDF from Downloads — not the original photo.
  • Wrong photo order. With Print to PDF, the selection order is the page order. In the browser tool, use the arrows to fix it before converting.
  • Skipping the check. Open the finished PDF and flip through it once. A sideways photo or a cropped edge is easy to miss until someone else finds it.
  • Converting one photo at a time for a multi-page document. Add all the photos in one conversion — separate one-page PDFs are fiddly to join later (though merging PDFs can rescue you).
