For one image on a device with Preview, Apple's built-in export may be enough. For several photos, explicit page ordering or A4/Letter output, use the HEIC to PDF converter. For mixed formats, use Image to PDF. A PDF is useful when the recipient asks for a document; use JPG when they need an editable photo instead.
Create a PDF in the browser
- Open the converter and select up to 10 HEIC/HEIF files, each no larger than 10MB. If Photos or a sharing app supplies JPEG instead, switch to Image to PDF.
- Wait for previews. Use the up/down buttons to establish page order; the filename does not determine the final order.
- Choose A4 or Letter for fixed paper, or Fit for image proportions. Select margins and image quality. Keep merge enabled for a single multi-page PDF.
- Convert, then tap Download. Several separate PDFs are downloaded as a ZIP. Save or share the downloaded result using the browser's file controls.
The images are processed on your device. Keep the tab open during conversion. If a large batch stops working, retry with one photo; compressed file size alone does not indicate memory use.
Built-in option: Preview on iOS 26
Apple's iOS 26 Preview guide describes opening an image, choosing Export from the filename menu, selecting PDF, and saving it. Menu names and availability depend on your iOS version. This native route is useful when you do not need this site's batch controls. These platform steps are based on Apple's documentation, not a claim of testing every iPhone.
Check the result before sending
| Check | What to look for |
|---|---|
| Page order and count | One page per selected image, in the chosen order |
| Small text | Read at 100%; higher quality cannot recover a blurred original |
| Shape and white space | Fit follows the image; fixed paper can leave white space |
| Saved file | Open the downloaded PDF itself before attaching it |
The browser converter embeds JPEG images in the PDF. It does not add OCR or preserve Live Photo motion, depth maps, original HDR rendering or complete EXIF data. Keep the HEIC original for editing or archiving. A document portal can impose its own size limit even when this tool accepts the source files.
If the file picker or export fails
Download the original from iCloud before retrying. Check the actual format and size in Files; changing an extension is not conversion. For an unsupported HEIC variant, export JPEG from a compatible Apple app and use Image to PDF. Apple explains HEIF sharing and conversion in its format support guide. Changing the camera's Most Compatible setting affects future captures, not existing HEIC files. More checks are in help.
Why A4 can leave space even with no margins
This worked example follows this tool's layout rules: A4 portrait, margins set to None, and the whole photo kept without cropping. These are calculated dimensions, not measurements on a particular phone.
| Source photo | Image on a 210 × 297 mm A4 page | Space above and below |
|---|---|---|
| Portrait, 3000 × 4000 px | 210 × 280 mm | 8.5 mm on each side |
| Landscape, 4000 × 3000 px | 210 × 157.5 mm | About 69.8 mm on each side |
The scale uses the smaller of available page width ÷ photo width and available page height ÷ photo height. Removing margins does not make different aspect ratios match. Choose Fit when a photo-shaped PDF is acceptable; use A4 when the recipient requires standard paper. Fit can produce a different page size for each image, so inspect the whole merged document. For paper printing, also check the printer's scaling settings; the PDF layout does not control them.
