HEIC Photo Conversion Checklist

Before converting an iPhone HEIC photo, and before sharing the result, these are the things worth checking — grounded in exactly how PDFPilot's HEIC tools work.

• Confirm the file is actually HEIC/HEIF — both tools check this and will tell you clearly if the uploaded file isn't a real HEIC photo, rather than producing a broken result.
• Choose JPG for sharing, uploading, or emailing — it's smaller and universally accepted. Open HEIC to JPG
• Choose PNG only if you specifically need lossless quality or transparency — otherwise it's a larger file for no practical benefit, since the source photo has neither transparency nor anything a lossy JPG would visibly lose. Open HEIC to PNG
• Expect the first conversion in a browser session to take a little longer — the HEIC decoder itself has to load once, then stays cached for the rest of the session.
• If the resulting image needs to fit a website or CMS's upload limits, resize it after converting rather than before — resizing the original HEIC isn't supported.
