Merge HEIC to PDF

How to Merge HEIC Photos into a PDF Online

1. Upload Your HEIC Files: Drag and drop or click "+ Add Files" to add multiple iPhone or iPad HEIC photos at once. Reorder pages by dragging them into the sequence you want; this becomes the page order in the final PDF.
2. Pick Combine Mode: Default is "Single PDF" (one document with one HEIC per page). Switch to "Individual PDFs" to output one PDF per photo — useful when each shot needs its own attachment for a claim or upload form.
3. Set Page Layout, Paper Size, Image Placement, Alignment, and Margin (Optional): Choose Portrait or Landscape under "Page layout"; pick A4 (default), Letter, Legal, A3, Tabloid, Ledger, Executive, ARCH A/B, ISO B4/B5, or "Original" (match each image's pixel dimensions) under "Paper size"; choose "Cover" (fill page, may crop) or "Contained" (fit with margins, no crop) under "Image placement"; set "Image alignment" to Top, Center (default), or Bottom; pick "No margin (0")", "Narrow (0.5")" (default), "Moderate (0.75x1")", "Normal (1")", or "Large (2x1")" under "Margin".
4. Tune Image Compression and Download: Adjust the "Image Quality (%)" slider (default 75) and pick a "Compression Type" preset — Screen (smallest file, default), Ebook, Default, Prepress, or Printer (highest quality). Click Merge. Files process in your browser session — no sign-up, no watermark.

Why Merge HEIC to PDF?

HEIC (High Efficiency Image Container) is Apple's implementation of the HEIF standard and has been the default still-photo format on iPhone and iPad since iOS 11 and macOS High Sierra shipped in September 2017. It uses HEVC (H.265) intra-frame compression to deliver roughly 40-50% smaller files than equivalent-quality JPEG. Outside Apple's ecosystem the format is patchier: native HEIC viewing arrived in Windows 11, requires the HEIF/HEVC extensions on Windows 10, and is still not decoded by any major desktop browser. Wrapping a batch of HEIC photos in a single PDF sidesteps all of that — every recipient on every OS opens it the same way.

• iPhone photo album for non-Apple recipients — A grandparent on Windows 10 or an Android-using friend can't always open a .heic attachment, but every device with a PDF reader can flip through your trip photos as one document.
• Insurance and warranty claims — Adjusters and warranty portals usually accept a single multi-page PDF more readily than a zip of HEICs. Use Portrait + Contained + Normal (1") margin so cropped subjects aren't cut at the edges.
• Real estate listings and property reports — A landscape PDF with Cover placement and No margin produces edge-to-edge property photos suitable for a tenant brochure or pre-listing report.
• Trip and travel albums — Combine a day's worth of iPhone shots into one PDF you can email, AirDrop, or post to a shared family folder. PDFs preview inline on iCloud, Gmail, and most messaging apps without any HEIC plugin.
• ID, passport, and document scans — iOS Camera saves Continuity Camera scans as HEIC. Merging the front and back of an ID into one PDF is what most KYC, school enrollment, and visa upload forms actually expect.
• Inspection, audit, and field reports — Contractors, home inspectors, and auditors often shoot dozens of HEIC reference photos per visit. Bundling them with a Letter or A4 layout produces a deliverable a client can archive alongside the written report.

Frequently Asked Questions

Do I need to convert HEIC to JPEG first before merging to PDF?

No. Upload .heic files straight from your iPhone or iPad and they're decoded server-side, then placed into the PDF. The Files app on iPhone has a "Create PDF" Quick Action, but as of iOS 18 that action only works on JPEG — HEIC photos go through a hidden Print-to-PDF workaround, and even then there's no batch reorder. Doing it here keeps the originals untouched and lets you set page order, layout, and margin in one pass.

Why is my merged PDF much larger than the sum of the original HEIC files?

PDFs embed images as JPEG (or sometimes JBIG2/Flate) — they don't carry HEVC streams. A 2 MB HEIC re-encoded to JPEG inside a PDF can land anywhere from 1 MB to 6 MB depending on dimensions and quality. To shrink the result, lower "Image Quality (%)" to 60-70 and stick with the Screen compression preset. To shrink it further after the fact, run the output through compress PDF or downscale the source images first with compress HEIC.

Should I use "Cover" or "Contained" for image placement?

Use Contained (default) when you can't afford to lose any of the photo — receipts, IDs, documentation, full-frame compositions. Contained scales each HEIC to fit inside the margins without cropping; portrait shots on a landscape page leave white bars on the sides. Use Cover for visual albums and listings where filling the page edge-to-edge looks better than preserving every pixel — Cover crops whichever dimension is too long.

What happens to HDR, Live Photo motion, and Depth data?

Only the still HDR image is rendered — Live Photo motion (the 3-second video sibling), depth maps from Portrait mode, and any auxiliary images in the HEIC container are dropped because PDF's image model has no place for them. The base photo's color is rendered in sRGB; Display P3 wide-gamut data is converted, so subtle color shifts are possible on highly saturated subjects. To preserve the motion or depth, keep the originals or convert separately with HEIC to MP4 for the Live Photo video.

Does EXIF metadata (GPS, capture time, camera model) survive?

The PDF stores a rasterized copy of each image, so per-photo EXIF inside the original HEIC is not embedded as searchable metadata — but the visible pixels and any printed timestamp burned into the image stay intact. If you need the metadata to follow the photos, keep the source HEICs alongside the PDF or run HEIC to JPG instead, which preserves EXIF inside the JPEG.

Which paper size should I pick — A4 or Letter?

Pick Letter (8.5 x 11 in) if recipients are in the US or Canada and may print the PDF; pick A4 (210 x 297 mm, the default here) for everywhere else. "Original" matches each HEIC's pixel dimensions to the page, which is handy for screen-only viewing but produces inconsistent page sizes if your shots have different orientations. For mixed-orientation albums, lock to A4 or Letter Portrait and let Contained placement handle the rotation.

Can I create one PDF per photo instead of a single combined document?

Yes — under "Combine?" pick "Individual PDFs". Each HEIC becomes its own single-page PDF, useful when an upload form or claims portal wants one file per attachment. If you also want to combine other image formats (JPG, PNG, WEBP) in the same PDF, use the more general merge image to PDF tool instead.

Will the PDF open on Windows, Android, and old browsers that can't read HEIC?

Yes — that's the main reason to do this conversion. PDF readers ship with every desktop OS (Preview on macOS, Edge or Acrobat on Windows, Okular/Evince on Linux), every modern browser opens PDFs inline, and every Android and iOS device has a built-in viewer. A merged PDF works on Windows 7 just as well as on iOS 18, which is more than HEIC itself can claim — Chrome, Firefox, Edge, and Safari all still refuse to render .heic natively.

Is there a file count or size limit?

Browser-uploaded conversions on xconvert run within your session in the browser; very large batches (hundreds of high-resolution HEICs) are bottlenecked by your device RAM and upload bandwidth more than by any hard cap. If a batch fails, split it into two halves, lower "Image Quality (%)" to 65, or pre-shrink the source images with compress HEIC before merging.
