convert iphone heic photos to pdf

If you're doing this conversion on the same iPhone the photos came from, or on a Mac, this tends to work reliably, since Apple's own platforms include HEIC decoding at the operating system level, which Safari (and often Chrome) can use directly. Uploading straight from your iPhone's browser is usually the smoothest path.

If you're instead trying to convert HEIC photos you've transferred to a Windows PC, expect a higher chance of the upload simply failing to decode, since Windows doesn't universally ship with a HEIC codec. This isn't specific to this tool — it's a platform-level gap that affects any browser-based HEIC handling on Windows.

For multiple iPhone photos at once, upload them all together and use the ◀ ▶ reorder buttons on each thumbnail to arrange them in your intended page sequence before generating a single combined PDF — useful for turning a batch of photos (receipts, whiteboard notes, a multi-page scanned document) into one document instead of separate files.

If you hit the Windows HEIC limitation, the cleanest workaround is changing your iPhone's own camera settings to "Most Compatible" instead of "High Efficiency" under Settings > Camera > Formats, which makes future photos save as JPG directly — no conversion step needed at all for anything captured afterward. For photos already saved as HEIC, exporting as JPG via the Share sheet works the same way as a one-off fix.
