HEIF to PDF Converter
FileFlip converts HEIF to PDF entirely inside your browser, using ImageMagick and MuPDF compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an HEIF file to PDF?#
- Drop your HEIF file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to PDF and the conversion starts on its own. FileFlip downloads 24.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick and MuPDF on your own machine.
- Save the PDF file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting HEIF to PDF lose quality?#
No. The HEIF picture is placed into the PDF document at its full resolution, so every pixel reaches it intact. What you give up is that it becomes a picture inside a document rather than text.
Is it safe to convert HEIF files online?#
Yes, because nothing is uploaded. FileFlip converts HEIF files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What HEIF to PDF actually does to the file#
Converting HEIF to PDF runs on ImageMagick and MuPDF, downloads 24.1 MB of WebAssembly the first time and nothing after that, places the picture into the document at full resolution, and drops EXIF metadata, ICC colour profile, animation frames and extra images.
| Engine | ImageMagick and MuPDF |
|---|---|
| Conversion path | 2 steps: HEIF → PNG → PDF |
| Downloaded to your browser | 24.1 MB, once, then cached by your browser |
| Quality | Pixels preserved |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| EXIF metadata | Dropped | The target format has nowhere to put it. |
| ICC colour profile | Dropped | The target format has nowhere to put it. |
| Animation frames | Dropped | The target format has nowhere to put it. |
| Extra images | Dropped | The target format has nowhere to put it. |
Worth knowing before you start:
- ImageMagick is asked for a single image, so only the first frame, page, or icon size is read
- the picture is placed in the document as a picture; no text is recognised out of it
What is an HEIF file?#
An HEIF file is a general-purpose container, built on the same ISO base media file format as MP4, that can hold one or more images encoded with any of several codecs, HEVC being the case Apple names HEIC and AV1 being the case standardized separately as AVIF.
Expect HEIF, rather than HEIC specifically, from cameras and devices that encode stills with a codec other than HEVC, since HEIF is the umbrella container those files also use.
Convert a HEIF file to JPEG or PNG when the destination only accepts a single, codec-agnostic raster image, since most upload forms and older software carry no HEIF decoder at all.
What is a PDF file?#
A PDF file records each character, image and line at a fixed position on the page, independent of any word processor's styles or fonts, which is what makes it print and display identically wherever it opens.
Use PDF to send a finished document to someone who needs to see the exact layout, on any device, without being able to accidentally change it.
Convert PDF to DOCX or another editable format when the real task is changing the wording, not just reading it, and accept that the layout will reflow rather than stay pinned in place.
HEIF to PDF questions people ask#
What's the difference between HEIF and HEIC?
HEIF is the container format, defined by ISO/IEC 23008-12, and it can hold images encoded with several different codecs. HEIC is specifically a HEIF file whose images are encoded with HEVC, which is the case Apple uses for iPhone and iPad photos, so every HEIC file is a HEIF file but not every HEIF file is a HEIC file.
Is AVIF the same thing as HEIF?
AVIF is a HEIF file whose images are encoded with the AV1 codec, in the same way HEIC is a HEIF file encoded with HEVC. The AVIF specification is written explicitly as a profile of HEIF, but it registers its own MIME type and extension because AV1 avoids the patent licensing that comes with HEVC.
Why does my camera save photos with a .heif extension instead of .heic?
Some cameras, including recent Canon and Sony models, encode HEIF stills for 10-bit HDR photography using a codec setup that isn't the HEVC-in-HEIF case Apple calls HEIC, so they label the file with the generic .heif extension instead. The underlying container is the same either way.
Does converting a PDF to Word preserve the original layout?
No, it reflows rather than preserves. A PDF fixes every line of text and image at an exact coordinate, while a Word document flows text into paragraphs and pages that adjust to fit, so a converter has to guess at paragraph breaks, headings and reading order from position alone. Simple single-column documents come through close to intact; multi-column layouts, text boxes and tables often don't.
