Camera-roll photos that need to become a PDF
The phone camera has replaced the office scanner for most people, but the places those photos need to go usually want a PDF, and often reject HEIC files outright:
- Receipts and expense reports. Snap each receipt during the trip, then hand in one PDF instead of a dozen attachments.
- School, visa and insurance forms. Upload portals often ask for a single PDF containing every page or supporting document.
- Multi-page documents shot page by page. A lease, a letter, a medical form or handwritten notes, one photo per page, combined in order.
PDF (ISO 32000) looks the same on every device, keeps pages in a fixed order, and travels as one attachment.
Multiple HEIC photos to one PDF in five steps
- Add the photos: select them, drag in a folder, or paste from the clipboard. JPG, PNG, WebP and AVIF can be mixed in.
- Choose a page size: Letter (the default), A4, or Fit to photo.
- Choose the order: by date taken (the default), by file name, or in the order added.
- Set a maximum size if the PDF is going by email or through an upload form; 1920 px is a good start.
- Convert and download your combined PDF.
Page size and order can be changed after converting without converting the photos again. Up to 500 photos fit in one batch, with no account and no watermark.
Letter, A4 or fit to photo
| Page size | Layout | Pick it for |
|---|---|---|
| Letter (8.5 × 11 in) | 0.5-inch margins; portrait or landscape chosen per photo | US and Canadian forms, anything printed in North America |
| A4 (210 × 297 mm) | Same margins and automatic orientation | Forms headed to Europe, Asia and most places outside North America |
| Fit to photo | Each page takes the photo’s own shape | Reading on screen, photo sets, files nobody will print |
Automatic orientation matters more than it sounds: a landscape shot of a wide receipt or a two-page spread gets a landscape page instead of being shrunk onto a tall one.
Putting the pages in the right order
The default order is by date taken, read from each photo’s EXIF data. For documents shot on an iPhone that’s nearly always right: photograph page 1, then 2, then 3, and the PDF follows the same sequence, even if the files arrive jumbled from a cloud download.
Switch to by file name when the names carry the order: iPhone numbers like IMG_4471 and IMG_4472 rise as you shoot, and files renamed 01, 02, 03 sort predictably. Choose order added for full control, adding photos one at a time in the sequence the pages should appear.
Keeping the PDF small enough to email
A full-resolution iPhone photo has far more pixels than a page needs, and a PDF with dozens of them can easily blow past an attachment limit or upload cap. The fix is the maximum size option:
- 1920 px on the long edge keeps receipts and typed documents readable on screen and on paper, at a fraction of the size.
- 1280 px for very strict limits; zoom in to check that small print and handwriting are still legible.
- 2560 px or original when fine detail matters, such as tiny type or technical drawings.
For a large PDF made somewhere else, such as an office scanner’s output, Compress PDF can shrink the photos inside it.
Color, quality and what stays out of the PDF
PDF can’t hold HEIC images as they are, so each photo is decoded and written into the PDF in a form every reader can display. Colors stay true: iPhones shoot in the wide Display P3 color space, and pd00 carries each photo’s ICC profile into the PDF as an ICC-based color space, so pages don’t look faded. HDR photos are converted to standard dynamic range.
What the PDF leaves out is a quiet privacy benefit: it doesn’t carry the photos’ EXIF data, including GPS coordinates, so a receipt photographed at your kitchen table won’t reveal where your kitchen is. Anything visible in the frame, like an address on an envelope, is still on the page, so cover it or frame it out when you shoot.
What this converter won’t do
- No text recognition (OCR). Pages are images, so the text can’t be searched or copied.
- No password protection, signing or text editing.
- Video is skipped. A Live Photo contributes its still; the .MOV is ignored.
- 500 photos per batch, in recent Chrome, Edge and Firefox, or Safari 16.4 or later (iPhone and iPad included).
Need the photos as separate images instead? Use HEIC to JPG. Want to add these pages to a PDF you already have? Convert first, then combine both with Merge PDF.
Receipts and forms stay on your device
IDs, bank letters and medical bills shouldn’t have to be uploaded to a stranger’s server, and here they aren’t. The photos are decoded (by libheif compiled to WebAssembly, downloaded once and cached) and assembled into a PDF inside your browser. The page’s Content-Security-Policy only permits connections to pd00.com and to Cloudflare’s anonymous page-view counter, which never sees your photos; every other destination is blocked, and once loaded you can go offline and keep working.
