PDF to HEIC Converter
Convert PDF pages into HEIC images. Upload a PDF to see why HEIC encoding isn't currently possible in any web browser, and get pointed to a working alternative.
No web browser can currently encode HEIC images. HEIC uses the patent-encumbered HEVC video codec, and there's no browser API or lightweight JavaScript library that can produce it. This tool will confirm that honestly rather than generate a mislabeled file.

Pro Tips
- •HEIC (High Efficiency Image Container) wraps HEVC-compressed image data, and HEVC is patent-encumbered with no royalty-free browser implementation for encoding
- •PDF to AVIF is the closest modern, highly-compressed alternative, though browser support for encoding it is also limited
- •PDF to WebP offers strong compression with much broader browser support today
- •This tool never generates a fake or mislabeled file - if conversion isn't possible, it says so clearly
Most Popular
Most users switch to PDF to WebP or PDF to JPG once they see HEIC isn't supported
When to Use This Tool
You might want HEIC output to match the format iPhones use for photos - though this specific conversion isn't currently possible in-browser.
HEIC is Apple's preferred format for photo storage, but generating it client-side in a browser isn't feasible with today's web platform.
Use this tool to understand why HEIC conversion is unavailable and get directed to a working alternative format.
Compare PDF to AVIF, WebP, or JPG as practical substitutes that achieve similar goals to HEIC with working browser support.
How It Works
Read the uploaded PDF file as binary data directly in your browser
Render the first page onto a canvas using the PDF.js library
Attempt to export the canvas as HEIC using the browser's native encoder
Detect that no browser currently supports this and show a clear, honest explanation instead of a mislabeled file
100% Private
Files never leave your device. All processing happens locally in your browser.
Lightning Fast
Powered by PDF.js + browser capability detection for optimal performance on modern browsers.
Open Source
Built with verified, open-source libraries. Fully transparent.
Frequently Asked Questions
Why can't any browser encode HEIC?
HEIC images are compressed using HEVC (H.265), a patent-encumbered video codec. Browser vendors haven't shipped royalty-free HEVC encoders, and there's no practical lightweight JavaScript library that can produce valid HEIC files either.
What should I use instead?
PDF to WebP offers strong, broadly-supported compression today. PDF to AVIF is closer in spirit to HEIC's efficiency but has limited encoding support. PDF to JPG remains the most universally compatible option.
Do browsers support viewing HEIC files, even if they can't create them?
Some browsers and operating systems can display HEIC images (particularly on Apple devices), but that's separate from being able to encode new HEIC files from a canvas, which is what this tool would need to do.
Is my PDF uploaded to a server?
No. The entire file is read and processed locally in your browser using the PDF.js library. Your document never leaves your device, regardless of the conversion outcome.
Will this tool ever actually produce HEIC files?
If browsers add native HEIC encoding support in the future, this tool would begin working automatically, since it checks for real browser support rather than assuming it isn't available.
