Getting started
Install PDF2IMG (v2.0.0 or later) from the App Store. Conversion stays on-device — nothing is sent to an external server.
Requirements
Section titled “Requirements”iOS 17.6+ or iPadOS 17.6+.
Import a PDF
Section titled “Import a PDF”Use any of these:
- Tap + or Import on the home screen, then pick a PDF from Files or iCloud.
- Open a PDF in Mail, Safari, or another app, then share it to PDF2IMG.
- Open Download file, paste a public PDF URL, and download it.
- Connect the iPhone to a Mac with a cable. In Finder, select the device → Files, then drag the PDF into PDF2IMG. Restart the app; the file shows up in the document list.
Choose pages
Section titled “Choose pages”After import, use the page grid: tap pages to select them, or use Select all / Deselect all at the top. Long-press or tap a thumbnail for a full-screen preview with pinch-to-zoom.
Then tap Merge long image or Export images at the bottom.
Layout and export
Section titled “Layout and export”- Long image: merge the selected pages into one vertical image.
- Multiple images: save each page as its own file.
You can set outer margin, spacing between pages, and background color. Positive values add space; negative values crop PDF edges, or overlap pages to hide headers and footers.
Resolution can be 72 / 108 / 144 / 300 DPI. Formats are JPEG, PNG, and HEIC.
Canvas layout (margin, spacing, background) and HEIC export are PDF2IMG Pro. Selecting pages, long-image / multi-image export, JPEG / PNG, and print-quality DPI stay free. See the FAQ.
Save and share
Section titled “Save and share”- Save to Photos: writes to the Photos library. The first time, allow photo-library access.
- Share: opens the system share sheet (AirDrop, Messages, Mail, and so on).
A very tall 300 DPI long image (dozens of pages) can exceed the Photos size limit. Drop to 144 DPI or 108 DPI, or export in smaller batches.
