Quick answer: open Toolzio's free JPG to PDF tool, drop in your JPG images, arrange them in the order you want, pick a page size and orientation, and click Create PDF. You download one PDF — images.pdf — with one image per page. Everything runs in your browser: no uploads, no account, no waiting on a server.

How to convert JPG to PDF step by step

  1. Open the JPG to PDF tool in your browser.
  2. Drop your JPG images onto the workspace (or click to browse). PNG images work too.
  3. Arrange the images in the order you want them to appear — use the up/down arrows next to each file. The PDF keeps exactly this order.
  4. Pick a page size: A4, Letter, or Fit. Pick an orientation: Auto, Portrait, or Landscape.
  5. Set the margin (0–72 pt) if you want white space around each image.
  6. Click Create PDF, then download images.pdf. Open it and flip through once before sending — check the order and that nothing is cropped.

Page size and orientation: which to pick

The settings exist because a photo and a page are different shapes, and the wrong choice crops or shrinks your image:

  • Letter — the right default for US readers: job applications, school forms, rental paperwork, anything filed or printed in the United States.
  • A4 — the international standard; pick it when the PDF goes abroad or to an organization that uses A4.
  • Fit — scales each image to fit the page without cropping. Use it when nothing may be cut off, like a photo of a signed document.
  • Auto orientation — lets each image's own shape decide; a wide photo gets a landscape page, a tall one a portrait page. Switch to a fixed orientation only when you want every page uniform.
  • Margin — the default 36 pt gives a clean border. Drop it to 0 when the image should fill the page, or raise it toward 72 pt for a formal, print-like look.

What about PNG, screenshots, and iPhone photos?

The tool accepts JPG and PNG, so screenshots — which are usually PNG — drop straight in. iPhone photos are the one wrinkle: iPhones often store photos as HEIC, which the tool does not accept. Save or export the photo as JPG first, then convert. Android photos are JPG already, so they work as-is.

Will converting hurt photo quality?

No, not in any way you can see. Your images are embedded at their original resolution, kept in proportion, and centered on each page — the conversion does not re-compress them the way re-saving a JPG does. Two honest caveats: a low-resolution source stays low-resolution (conversion cannot add detail), and if the finished PDF is too large to email, that is a file-size problem — see our guide on compressing a PDF without losing visible quality.

Common problems (and how to fix them)

  • Wrong page order: reorder with the arrows before converting. If the PDF is already made, fix the order with the Organize PDF tool instead of starting over.
  • Image cropped at the edges: switch page size to Fit, or raise the margin, or set orientation to Auto so wide images get landscape pages.
  • Sideways photo: the tool keeps the image's stored orientation; rotate the photo in your phone or computer first if it opens sideways there too.
  • HEIC file rejected: export it as JPG first — the tool accepts JPG and PNG only.
  • One photo, many pages: every image becomes one page by design. If you need separate PDFs per photo, convert one image at a time.

Honest limitations

  • No searchable text. The PDF contains images, not text — words in a photographed document cannot be selected, searched, or copied. You would need OCR software for that.
  • No image editing. Cropping, rotating, or brightening has to happen before conversion, in your photos app.
  • One combined PDF per conversion. If your photos belong in different documents, convert them in separate batches.

Once your photos are a PDF, the next step is often combining it with other documents — see our guide on how to merge PDF files — or going the other way, turning PDF pages back into images with the PDF to JPG tool.
