How to use it
Good for
People convert HEIC to PDF when their photo's container format is blocking the next step in a workflow that already accepts PDF. iPhones default to HEIC for the storage and compression gains, but a large slice of the receiving systems people actually have to deal with — HMRC self-assessment, US tax portals, NHS appointment uploads, council benefit applications, university coursework drop-boxes, expense management tools, payroll evidence portals, and standard email clients running on Windows 10 — silently fail or mis-render HEIC. The cheapest fix is wrapping the photo in a PDF, because PDF is the lowest-common-denominator document format on every platform from a 2014 Windows laptop to a kiosk PC at a council reception. The same tool also helps when several HEICs need to land at the destination as a single document — a series of receipts as one expense claim, a set of meter readings as one utility submission, a four-page handwritten signed form scanned in pieces. The tool works in your browser, encodes each photo as a JPEG at quality 0.92 and embeds it into the PDF. This avoids handing photos to a third-party server purely to swap a container.

Questions
HEIC needs a codec on Windows 10 and earlier, and a paid Microsoft Store extension on most Windows 11 builds. Most Outlook, Gmail, and Teams recipients haven't installed it, so they see a broken-image placeholder. Converting to PDF removes the codec dependency entirely — every PDF reader on every OS handles the conversion output without any setup.
There is one lossy step. Libheif decodes the HEIC, then the tool encodes a JPEG at quality 0.92. It embeds that JPEG in the PDF without another image encode. The result is not bit-for-bit identical to the source. Keep the original HEIC when source quality matters.
Yes. Android phones rarely default to HEIC, but Samsung Galaxy and a few Huawei models do offer it as an option. The decoder handles HEIC and HEIF regardless of capture device — it inspects the file's actual format markers, not the device that produced it.
Each HEIC must be under 100 MB and a single batch can hold up to 50 photos. Those caps protect lower-RAM devices from running out of memory mid-conversion. If your batch is larger, split it into runs of 50 — each run produces one PDF, and you can merge the PDFs afterwards with the Join PDFs tool on this site.
Conversion time depends on the number and resolution of the photos and the available device memory. Progress appears in the status line as each photo is decoded and added to the PDF.
No. The converter writes a fresh PDF from the decoded pixels, and in our tests the GPS location and other camera EXIF tags from the HEIC were not carried over. Keep the original HEIC if you need that information.
Yes. Everything this tool does is free. On some tools, a Day or Project Pass raises the file-size and batch limits if you need more.
