How it works
From HEIC to PDF, in three steps
- 01
Decode
Your HEIC file is decoded to raw pixels locally, using a WebAssembly build of libheif.
- 02
Build PDF
The decoded image is placed as a full page inside a new PDF, using pdf-lib.
- 03
Download
Your PDF downloads straight to your device. It never touched a server.
Drag your .HEIC or .HEIF photos into the box above, or click it to choose files from your device. The output format is already set to PDF, so each photo you drop becomes its own ready-to-download PDF document.
Your browser decodes each HEIC file with a WebAssembly build of libheif in a background worker, then builds a PDF around the decoded image using pdf-lib, all locally, entirely inside the current browser tab. Nothing is uploaded to a server at any point.
Convert one photo or a whole batch, track each file's progress individually, and download the results one at a time or together as a single .zip of PDFs.
When you need this
Submit it as a document
PDF is the format of choice whenever a photo needs to be submitted, archived, or printed as a document rather than handled as a loose image file: think ID or receipt photos for a form, a scanned-looking document shot on a phone, or photos that need to sit alongside other paperwork in one file.
When a form asks for PDF
Reach for HEIC to PDF conversion when an online form, an email attachment policy, or a print shop specifically asks for PDF, or when you simply want a single, self-contained file instead of a folder of images.
Worked example
Say you photographed a signed contract page on an iPhone, saved as a 2.2 MB HEIC file, and the recipient's submission portal only accepts PDF.
Drop the file into the box (PDF is already selected) and click "Convert." The HEIC decodes locally, and a one-page PDF is generated around the full-resolution image in about a second, sized to match the photo's own dimensions. Download the PDF and submit it directly: no separate PDF software, no upload to a third-party converter, and the original photo never left your device.
Format explainer
PDF (Portable Document Format) isn't an image compression format so much as a document container. This tool places each converted photo as a full-page image inside its own single-page PDF, preserving the photo's original pixel dimensions.
That's different from JPG and PNG, which are image formats controlling how pixel data itself is compressed. If what you actually need is a smaller or losslessly accurate image file, JPG or PNG output is the better fit; choose PDF specifically when the destination (a form, an email policy, an archive) expects a document file rather than an image file.
Frequently asked questions
Not with this tool as it stands. Each photo becomes its own single-page PDF, matching how the batch queue shows one result per file. Convert five photos and you'll get five separate PDFs, downloadable individually or together as one .zip, not one combined multi-page document. Merging them afterward would need a separate PDF-merging tool.
Yes. Each PDF page is sized to the decoded image's exact pixel dimensions, and the photo is placed full-bleed with no cropping or scaling.
No. HEIC decoding and PDF generation both happen locally in your browser using WebAssembly and a background worker. No file is ever sent to a server.
Yes. Drop as many files as you need, click "Convert all," and download each PDF individually or together as a single .zip.
Those files can contain multiple images in one container. This tool automatically picks the primary photo out of the container and converts that one to PDF.
Drop your HEIC photo into the box above. PDF is already selected. Your browser decodes it and builds a one-page PDF sized to the photo's own dimensions, ready to download in about a second.
No differently than on any other device: this runs in your browser instead of relying on Windows' own HEIC support, so there's nothing to install first. Drop the file in and download the PDF.
macOS Preview can also export a HEIC straight to PDF (File > Export As PDF), so you're not strictly stuck without a separate tool. This page is quicker once you're converting several photos, since it batches them instead of exporting one at a time.
Open this page in Safari and convert the same way as on a computer. There's also a built-in trick worth knowing: open the photo, tap Share > Print, then pinch out on the print preview. That turns it into a PDF you can share, with no separate tool needed.
