Can I combine more than one PNG into a single PDF?

Yes — upload as many PNG images as you need and they will all be combined into one PDF, one image per page.

What order will my images appear in?

Images are placed in the order you uploaded them — rename your files with numeric prefixes if you need a specific sequence.

Will converting to PDF reduce my image quality?

No — each PNG is placed on its own page at its original, lossless quality.

Do I need an app from the App Store?

No — it works directly in Safari or Chrome on iPhone, with nothing to install from the App Store.

Can I use the Files app or Photos to upload?

Yes — use the Share Sheet from either app to send a file straight into the upload dialog.

Convert

PNG to PDF on iPhone

iOS doesn't come with a full PDF toolkit built in beyond very basic viewing, and installing a dedicated app just for an occasional task is overkill for most people. My PDF works directly in Safari or Chrome on iPhone, using the same Files app or Photos share sheet you already know.

Why This Matters

What Is a PNG to PDF Converter?

A PNG to PDF converter combines one or more PNG images into a single PDF document, in the order you upload them, so a set of separate PNG files — screenshots, diagrams, exported graphics — can be shared, printed or filed as one cohesive document instead of a loose collection of image files.

Step by Step

How to PNG to PDF on iPhone

Upload Your PNG Images

Drag in the images you want to combine, in the order you want them to appear, or click to browse and select them. On iPhone, tap the upload area and choose Photos or Files, or use the Share Sheet from either app.

Confirm Your Images

Review the list of uploaded files before continuing.

Click Convert to PDF

Our server places each image on its own page and combines them into one PDF, typically within seconds.

Download Your PDF

Save your combined document, ready to share, print or file.

Tips

Name Files to Control Order — Prefix filenames with 01-, 02-, 03- so your images upload — and convert — in exactly the sequence you want.
Use PNG for Anything With Text — Screenshots and diagrams with text stay noticeably sharper as PNG than they would after JPG compression.
Use the Share Sheet from Photos or Files to send an image or document straight into the browser's upload dialog.
iPhone screenshots and photos are usually already in JPG or PNG format, so they work directly with no extra conversion step first.

Avoid These

Common Mistakes

Uploading a file that is already password-protected without unlocking it first — most operations require an unencrypted starting file.
Assuming a converted or compressed file replaces the need for the original — keep your source file until you have confirmed the result looks right.
Not checking the 50 MB upload size limit before starting, then wondering why a very large scan fails to upload.
Installing a separate PDF app from the App Store for a single occasional task instead of using the browser already open.
