How to convert screenshots and PNGs to PDF on iPhone
By DeckleUpdated
To convert screenshots and PNGs to PDF on iPhone, open PNG to PDF in Safari, tap Select files and choose the screenshots, put them in order, choose Fit inside A4 and tap Create PDF. Each screenshot becomes one page of a new PDF, with its pixels kept exactly. The images on your phone are not changed. On iOS 26 and later, the Preview app can also export an image as a PDF; see below.
How to turn screenshots into a PDF on iPhone with Deckle
- Open PNG to PDF in Safari, or another browser.
- Tap Select files and choose the screenshots from your photo library or the Files app.
- Under Images to include, check the ticks and use the up and down arrows to set the order.
- Press the rotate button on any image that needs turning. Preview on a row shows the image on its page.
- Under Page size, choose Fit inside A4 and Portrait for phone screenshots. Under Margin in points, Narrow works well.
- Optional: set Output PDF name.
- Tap Create PDF and download the file.
The result screen confirms how many pages the PDF has, one per ticked image.
Why Fit inside A4
An iPhone screenshot is tall and narrow, often around 1170 × 2532 pixels or more. With Match each image, each page becomes that size in points, about 16 × 35 inches, which looks odd when printed or attached to a document. Fit inside A4 puts each screenshot on a standard A4 page, shrunk to fit, without cropping it. Every pixel is still there when you zoom in.
Example: five screenshots of an order confirmation, a delivery message and a chat with customer support make a five-page A4 PDF you can attach to a complaint or claim.
Photos are a different matter
Deckle keeps up to 4 megapixels per page on iPhone and iPad, so that Safari doesn't run out of memory. iPhone screenshots fit under that: even a Pro Max screenshot is under 4 megapixels. Screenshots from the largest iPad Pro can go over it, and are scaled down to 4 megapixels with their proportions kept. Camera photos are 12 megapixels or more, so they are scaled down too: a 24-megapixel photo keeps about a sixth of its pixels, which is fine for reading and sharing. Photos above 25 megapixels, such as 48-megapixel shots, are refused on iPhone and iPad.
| Image | On iPhone |
|---|---|
| Screenshot (PNG) | Converts with PNG to PDF |
| Camera photo (HEIC or JPG, 12 to 24 MP) | Scaled to 4 MP; convert on a computer for more detail |
| Camera photo at 48 MP | Refused; convert on a computer or set the camera to 24 or 12 MP |
| Small JPG, such as a saved web image under 4 MP | Converts with JPG to PDF |
For full-detail camera photos, send them to a Mac or PC, where photos keep up to 16 megapixels, and follow how to convert HEIC to PDF on a Mac or on Windows, or use Preview on the iPhone.
Export an image as a PDF with Preview on iPhone
Apple's page Export or compress PDFs and images in Preview on iPhone covers this, for iOS 26 and later:
- Open the image in the Preview app.
- Tap the button next to the file name, then tap Export.
- Choose PDF as the format and confirm.
- Choose where to save it, rename it in the Save As field if you like, and tap Save.
That makes one PDF per image. To add more images to the same PDF, Apple's page Add, delete, rotate, move, or crop PDF pages in Preview on iPhone describes Insert from File, which accepts images. Deckle does a batch of screenshots in one step.
Tips
- Crop screenshots first. Cropping out the status bar and keyboard makes the PDF easier to read.
- Check the order. Read down Images to include before you create the PDF, and use the arrows to fix anything out of place.
- Text in screenshots isn't searchable. The page holds a picture.
- Combine with other PDFs. Merge the result with other documents in Merge PDFs; see how to merge PDF files on iPhone and iPad.
Frequently asked questions
How do I make a PDF from screenshots on my iPhone?
Open PNG to PDF in Safari, select the screenshots, choose Fit inside A4 and tap Create PDF.
Why was my photo refused?
It is over 25 megapixels, the most iPhone and iPad accept, as a 48-megapixel photo is. Convert it on a computer, where photos up to 64 megapixels are accepted and scaled to 16 megapixels.
Are my screenshots uploaded?
No. The PDF is built in Safari on your iPhone.
Is the quality reduced?
No. PNG to PDF keeps every pixel with lossless compression.
