Need help?PDF to HEIC Converter
PDF is a document container that holds vector text, fonts, and layout; HEIC is Apple's high-efficiency image format that stores a single rendered picture. Converting PDF to HEIC rasterizes each page into a flat HEIC image — useful when you want a small, photo-style snapshot of a page inside the Apple Photos ecosystem rather than an editable document. The trade-off is that the output is a picture: the text becomes pixels and is no longer selectable or searchable.
What HEIC Is, and What This Conversion Produces
Each PDF page is rendered to a bitmap at the DPI you choose, then encoded as HEIC. Because HEIC uses HEVC (H.265) intra-frame compression, the resulting image is typically around half the size of an equivalent JPEG at similar visual quality — which is why it is a sensible target when you are storing page snapshots on an iPhone, iPad, or Mac. Outside the Apple ecosystem, HEIC support is limited, so most people keep a JPEG or PNG copy for sharing. If you need selectable text or universal compatibility, render to PDF to JPG instead.
HEIC Format at a Glance
| Property | Value |
|---|---|
| Standard | ISO/IEC 23008-12 (MPEG-H Part 12, "HEIF") |
| Released | 2015 (MPEG); Apple adopted it in iOS 11, 2017 |
| Container | ISO Base Media File Format (ISO/IEC 14496-12) |
| Image payload | HEVC (H.265) intra-coded |
| Extension meaning | .heic = HEVC-encoded HEIF (vs generic .heif) |
| Color depth | 10-bit and higher supported (vs JPEG's 8-bit); editors like Photoshop may read only 8-bit |
| Transparency | Yes, via auxiliary alpha-plane items |
| Native browser support | Safari 17.0+ on macOS and iOS only — not Chrome, Firefox, or Edge (caniuse) |
| Best for | Storing page snapshots compactly inside Apple Photos |
PDF Format at a Glance
| Property | Value |
|---|---|
| Standard | ISO 32000 (PDF 2.0 = ISO 32000-2, 2017) |
| Released | 1993 (Adobe); ISO-standardized in 2008 |
| Content model | Vector text, fonts, raster images, and layout in one file |
| Text | Selectable and searchable (lost when rasterized to HEIC) |
| Pages | Multi-page; PDF to HEIC outputs one image per page |
| Native browser support | All modern browsers render PDF directly |
| Best for | Sharing documents that must look identical everywhere |
How to Convert PDF to HEIC
- Upload Your PDF File: Drag and drop your PDF onto the page or click "+ Add Files" to pick it from your computer. Multi-page PDFs produce one HEIC image per page.
- Set Conversion Quality (DPI): Open Advanced Options and choose a render DPI. The default 300 DPI is print-grade; 150 DPI is fine for on-screen viewing and yields smaller files.
- Pick Image Compression and Color: Under Image Compression, leave Quality Preset on "Very High (Recommended)" or set a Specific file size; under Image Transparency, choose the background color for the rendered page.
- Convert and Download: Click "Convert" and download your HEIC. No sign-up, no watermark.
Frequently Asked Questions
Does the HEIC output keep the PDF's selectable text?
No. PDF to HEIC rasterizes each page into a flat image, so text, links, and form fields become pixels — they are no longer selectable, searchable, or copy-pasteable. If you need the text to stay live, keep the PDF or convert to a format that preserves it; HEIC is strictly an image target.
Why would I convert a PDF to HEIC instead of JPG or PNG?
Almost the only reason is Apple-ecosystem storage efficiency. HEIC's HEVC compression makes the rendered page roughly half the size of an equivalent JPEG at similar quality, which adds up when you keep many page snapshots in Apple Photos on an iPhone or Mac. For anything you plan to share or open on Windows or Android, JPG or PNG is the safer choice.
Can Windows or Android open the HEIC files this produces?
Natively, no — browser support is Safari 17.0+ only, and out of the box Chrome, Firefox, and Edge do not display HEIC. Windows can open it after installing Microsoft's HEIF/HEVC codecs from the Microsoft Store, and recent Android versions have growing support, but compatibility is far from universal. To view a page anywhere, convert the HEIC back with HEIC to JPG.
What DPI should I choose for PDF to HEIC?
Match the DPI to how the image will be used. 300 DPI is print-grade and the recommended default; 150 DPI is plenty for on-screen viewing and produces noticeably smaller files; 72-96 DPI suits thumbnails. Higher DPI means a sharper, larger image and a longer render, so there is no benefit to exceeding the resolution your display or printer can actually show.
Is HEIC really smaller than JPEG for the same page?
Usually yes. In our testing, a single text-and-graphics PDF page rendered at 150 DPI came out a few hundred kilobytes smaller as HEIC than as a JPEG at comparable visual quality, consistent with HEIC's roughly 50% compression advantage. The gap is largest on detailed, photographic pages and smallest on sparse, mostly-white pages where both formats are already tiny.
Does HEIC support transparency for pages with no background?
The HEIC format itself supports an alpha channel via auxiliary image items, but a rendered PDF page is normally flattened onto a solid background. Use the Image Transparency control to set that background color (white is the default). If you specifically need a transparent background, PNG is the more reliable target for this conversion.
How large a PDF can I upload?
There is no per-page count limit and no watermark. The practical ceiling is upload size and your connection speed rather than the document itself — a long, image-heavy PDF takes longer to upload and render than a short one. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours; nothing is shared or made public.
