How to convert a PDF to JPG on iPhone

By DeckleUpdated

To convert a PDF to JPG on iPhone, open PDF to JPG in Safari, tap Select a file and choose the PDF, set Resolution to Standard, keep All pages or type the pages you need, then tap Export images. You get one JPG per page, which you can save or share from your phone. The PDF is not changed, and nothing needs to be installed.

How to convert a PDF to JPG on iPhone with Deckle

  1. Open PDF to JPG in Safari, or another browser.
  2. Tap Select a file and choose the PDF from the Files app.
  3. Under Resolution, choose Standard. It is the highest setting that fits a full A4 or Letter page on a phone.
  4. Under JPEG quality, keep Balanced, or choose Smaller or Maximum.
  5. Under Pages, keep All pages, or choose Choose pages and type numbers such as 1, 3-5.
  6. Tap Export images.
  7. Download each JPG, or use the button that reads Download all … as a zip for every page in one file.

The result screen tells you how many images were made, which should match the pages you chose.

Why Standard, not Print

Deckle limits each image to 4 megapixels on iPhone and iPad, so Safari doesn't run out of memory. At Print (300 DPI), an A4 page is about 8.7 megapixels, which is over the limit. Every page is checked before the first image is written, so if one is too large, nothing is exported and the message names the page.

Resolution A4 page in pixels On iPhone
Screen (72 DPI) about 595 × 842 Works; small files for previews
Standard (150 DPI) about 1240 × 1754 Works; sharp on a phone screen and in messages
Print (300 DPI) about 2480 × 3508 Too large on iPhone; use a computer

Standard is sharp enough for sharing in messages, adding to social posts and most uploads. If you need print resolution, convert the PDF on a Mac or PC, where the limit is 16 megapixels. See how to convert a PDF to JPG on a Mac.

Save the images to Photos

The JPGs download as files. To put one in your photo library, open it from Safari's downloads or the Files app, tap the share button and choose the option to save the image. A ZIP holds every page in one download; open it in the Files app to reach the images.

Each image is named after the PDF with the page number, such as menu-002.jpg, so pages stay in order when you share several.

Export with Preview on iPhone

On iOS 26 and later, the Preview app can export a PDF in another format. Apple's page Export or compress PDFs and images in Preview on iPhone lists JPEG and PNG among the formats, with a Resolution setting when you export a PDF to an image:

  1. Open the PDF in the Preview app.
  2. Tap the button next to the file name, then tap Export.
  3. Choose JPEG, set the Resolution and drag the Size slider towards quality or a smaller file.
  4. Confirm, choose where to save the image and tap Save.

Apple's page does not say how a PDF with several pages is exported, so check the saved images against the pages you need. With Deckle you choose the pages, and each image is named with its page number.

What a JPG of a page contains

Each JPG is a picture of the whole page as it renders, on a white background. Text becomes pixels, so it can't be selected, and links don't work. For pages of text or diagrams, PDF to PNG keeps edges sharper. See PDF to PNG or JPG: which to choose.

Tips

  • Export one page for a quick share. Type its number in Choose pages, such as 2.
  • Use JPG for messages. Many chat apps show a JPG inline, where a PDF arrives as a file to open.
  • Unlock first. A PDF that asks for a password can't be exported; use Unlock PDF with the password you were given.
  • Keep the PDF for printing. The original PDF prints sharper than any image of it.

Frequently asked questions

How do I turn a PDF into a picture on my iPhone?

Open PDF to JPG in Safari, choose Standard and tap Export images.

Why did the export stop?

A page is over the 4-megapixel limit at the chosen resolution. Choose Standard or Screen, or export on a computer.

Is my PDF uploaded?

No. The pages are rendered and the JPGs are created in Safari on your iPhone.

Can I convert just one page?

Yes. Choose Choose pages and type the page number.

Which quality should I choose?

Balanced (92%) suits nearly everything. Smaller (75%) makes lighter files for slow connections; small text softens first. Maximum (100%) gives the largest files with little visible gain at Standard resolution.
