Convert photos to PDF now

Job portals, visa forms, schools and banks often ask for documents as a PDF, but most of us only have photos of them on our phone. You do not need a computer or an app to fix this. You can turn one photo, or many photos, into a single PDF right in your phone's browser in about a minute.

Short version: open Images to PDF on your phone, choose your photos, put them in order, keep the page size on A4 and press the button. Your PDF downloads to your phone.

Step by step on iPhone

  1. Open Safari and go to janjuapdf.com/jpg-to-pdf.
  2. Tap the box that says Click to choose files, then tap Photo Library. You can also tap Take Photo to photograph a document right now.
  3. Select all the photos you want and tap Add.
  4. Check the order in the list. Use the up and down arrows to move a photo.
  5. Leave Page size on A4 and Image quality on Standard, then tap Images to PDF.
  6. Tap Download images.pdf. Safari saves it in the Files app, in the Downloads folder.

Step by step on Android

  1. Open Chrome (or any browser) and go to janjuapdf.com/jpg-to-pdf.
  2. Tap Click to choose files. Choose your photos from the gallery, or use the camera option if your phone shows it.
  3. Put the photos in the right order with the arrows.
  4. Keep A4 and Standard quality, then tap Images to PDF.
  5. Tap Download images.pdf. You will find it in the Files or My Files app, inside Downloads.

Before you send the file, open it once and scroll through every page to check that nothing is missing or upside down.

Tips for clear, readable pages

Common problems and how to fix them

The PDF is too big for the upload form

Many forms only accept small files. Create the PDF with Standard quality. If it is still too large, run it through Compress PDF and pick a Target size such as Under 200 KB. See How to Compress a PDF to 100KB or 200KB.

A page is sideways

The tool follows the direction your phone saved with the photo, so pages normally come out the right way up. If one is still sideways, fix it with Rotate PDF.

A photo is skipped or will not open

The tool works with JPG, PNG and WebP photos, and with iPhone photos chosen from the Photos library in Safari. If one image still fails, take a screenshot of it and add the screenshot instead.

The pages are in the wrong order

You do not have to start again. Use Reorder PDF Pages to move pages in the finished PDF, or Delete PDF Pages to remove a page you added by mistake.

I need to add these pages to another PDF

Create the PDF from your photos first, then join it with your other file using Merge PDF. See How to Merge PDF Files.

Other free ways to do it

Your phone also has built-in scanners. On iPhone, the Notes and Files apps include a Scan Documents option. On Android, the Google Drive app has a Scan option. These work well when you are taking new pictures. JanjuaPDF is handy when the photos are already in your gallery, when you want to choose the page size and quality, or when you want to keep using the same simple tools to merge, compress or rotate the result.

Is it safe for personal documents?

Yes. Everything happens inside your browser and your photos are not uploaded to our servers. This matters for ID cards, bank papers and certificates. Still, only send personal documents to websites and people you trust.

Frequently asked questions

Is it free to convert photos to PDF on JanjuaPDF?

Yes. The Images to PDF tool is free, needs no signup and adds no watermark.

Are my photos uploaded to a server?

No. The PDF is created inside your phone's browser, so your photos stay on your device.

How many photos can I put in one PDF?

You can add many photos, and each photo becomes one page. On older phones, very large batches can be slow, so split them into groups of about 20 and merge the PDFs afterwards.

Why is my PDF too big to upload?

Phone photos are large. Choose Standard quality when you create the PDF, and if it is still too big, use Compress PDF before uploading.

My iPhone photo will not open. What should I do?

Use Safari and choose the photo from your Photos library, which usually converts it to JPG automatically. If it still fails, take a screenshot of the photo and use the screenshot instead.
