Free HEIC to PDF Converter: No Sign-up, Files Never Uploaded
Turn HEIC files into PDF for free, with no sign-up and no upload. The conversion happens in this tab, so your files never leave your computer or phone.
The picture is decoded into pixels and encoded again as PDF, one file at a time, on your own processor.
This pair runs on code that is already in the page, so there is no extra engine to download.

Supported formats
About the formats
About HEIC
The default photo format on iPhones since iOS 11.
Uses the HEVC codec, so files are often about half the size of a JPEG at similar quality.
Many apps and websites cannot open it, which is why it is usually converted to JPG.
About PDF
Fixed-layout document format that looks the same on every device.
Created by Adobe and standardised as ISO 32000.
Hard to edit, which makes it the usual format for sharing finished documents.
HEIC vs PDF
HEIC supports transparency, and PDF does not.
HEIC files use the .heic extension and PDF files use .pdf, so the converted file gets a new name with the new extension.
Privacy: how it works
- Your HEIC files stay on your device. The page reads each file with the browser's file API, converts it with code running in the tab, and hands the result back as a download. No upload happens, so there is no copy of your file on our servers to protect, delete or leak.
- There is nothing to sign up for and no login. The converter does not ask for an email address, and it does not need to know who you are to do its job.
- You can check the claim yourself: open your browser developer tools, watch the Network tab while a file converts, and you will see no request that carries your file.
Tips
- Keep your original file. A lossy format cannot be turned back into the exact original pixels.
- Pick the quality setting by looking at the result, not by guessing: a lower value gives a smaller file and a visible loss of detail.
- Convert logos and screenshots to a lossless format, and photographs to a lossy one, to keep file sizes sensible.
- Resize before converting when the picture is much larger than where you will use it.
- This page converts one way only; PDF files cannot be turned back into HEIC here.
Frequently asked questions
Is it really free?
Yes. There is no price, no trial, no credit card and no watermark added to your results. Ulkaa Tool does the conversion with your own device, so there is no server bill to pass on to you.
Are my files uploaded?
No. Your HEIC files are read and converted inside your browser and are never sent to Ulkaa or to anyone else. The result is created on your device and you save it from there.
Do I need an account?
No. There is no sign-up and no login. Open the page, add your files and convert. An Ulkaa account is not needed for anything on this tool.
Is there a file size limit?
No limit is set by us. The real limit is your device: the conversion uses your own memory and processor, so very large files can be slow, and a very big batch may need to be split into smaller runs.
What is the difference between HEIC and PDF?
HEIC supports transparency, and PDF does not. HEIC files use the .heic extension and PDF files use .pdf, so the converted file gets a new name with the new extension.
Can I convert many HEIC files at once?
Yes. Add as many files as your device can handle. Each one is converted on its own and you can download them one by one or as a single ZIP.
Will anything be lost when I convert HEIC to PDF?
The converter keeps the content of the file. Check the result once, since small differences in metadata or colour handling can happen between formats.
Can I convert PDF back to HEIC?
Not on this page. This conversion goes one way. Open the PDF page to see which formats it can be converted to.
