Short answer: open the free JPG to PDF converter, add all your images, arrange them with the ↑ ↓ buttons, choose A4 or Letter and click Create PDF. Every image becomes one page in a single PDF. It works the same on Android, iPhone, Windows and Mac.
Universities, embassies, employers and banks often want documents as one PDF — not ten separate photos. Here is the quickest way to do it without installing an app.
Step-by-step
- Take clear photos. Lay each page flat in good light and hold the phone directly above it.
- Crop the edges. Remove the table or background with the crop tool so each page fills the PDF neatly.
- Open JPG to PDF and add all the images. JPG, PNG, WebP and iPhone HEIC are accepted.
- Put the pages in order using the arrow buttons.
- Choose page settings. A4 for most countries, US Letter for the USA and Canada. Leave orientation on Auto so landscape images are rotated correctly.
- Create and download your PDF.
Make the PDF small enough to upload
Many portals limit PDF uploads to 1–2 MB. Phone photos are large, so shrink them first:
- Compress each image with compress to 200 KB (good for readable text), then create the PDF.
- For a five-page document that gives a PDF of roughly 1 MB.
Already have several PDFs?
If some documents are already PDFs, create a PDF from your images first, then join everything with Merge PDF.
Which page size should I use?
| Option | Use when |
|---|---|
| A4 | Submitting or printing documents in Asia, Europe, Africa, Australia |
| US Letter | Submitting or printing in the USA or Canada |
| Same as image | Photo albums or screenshots that will only be viewed on screen |
Privacy
Certificates, ID cards and bank statements are sensitive. The PixelTight converter builds the PDF inside your browser, so your documents are never uploaded to a server.
