The contract you photographed is already in the camera roll; it just is not a document yet.
The camera roll is where documents end up
A lease signed on a kitchen table, a receipt, a passport page, a doctor's note, the
homework of a child who forgot the sheet at school: the fastest way to keep any of them is
to photograph it with the iPhone. The result is a .heic sitting between holiday snapshots,
which is fine for looking at and useless for sending to an office.
HEIC is a problem on the other side
Windows only draws a HEIC after two add-ons from its store, one of which is paid, and older
versions never manage it; plenty of Android phones and web forms refuse the file outright,
and an email portal that checks the attachment type will not accept it at all. A PDF is the
opposite: every phone, PC, printer and office program opens it without a plug-in.
Six photos become one document
Photographing a six-page contract leaves six loose files in an album. In a PDF they are
pages 1 to 6 in the order you chose, upright, on the paper you picked — a document the
other side can file, print and forward without renaming anything.
How the pages are ordered
A photographed document is only in the right order if you say so — the list in front of you is
the PDF.
Add page one first
Files are appended in the order they arrive, and the first row becomes page 1. Pick the
photos from the Photos app in the order you want them, or add the title page on its own
first and the rest afterwards; each row shows a file name and size, because a browser
cannot draw a HEIC thumbnail.
Move a row with the arrows
Each row has ↑, ↓ and ×. The arrows swap
a row with its neighbour and renumber the list immediately; the cross removes it. Rows
cannot be dragged — a drag is read as new files and appends them — so the buttons are the
reliable way to fix the order, and they work on a phone and with a keyboard.
Several passes are fine
Take the photos, add the first batch, then use Add more for the rest: each
batch lands after the previous one and keeps its own order. Nothing is converted until you
press the button, so the sequence can be rearranged as often as needed. The list stops at
30 images.
Page size, orientation and margin
Paper for something that will be printed, a fit-to-image page for something that will be placed
elsewhere.
A4
210 × 297 mm and the default, because a photographed page is nearly always going to be
printed or filed on it. The photo is scaled down to fit inside the printable area, keeps
its proportions and is centred, so a portrait shot of a sheet lands on a portrait page with
a clean border.
US Letter
216 × 279 mm, the standard sheet in the United States and Canada. Same layout rules as A4 —
fitted, centred, never cropped — and the right choice when the document will be printed
there or an office in that country asked for it.
Fit to image
The page becomes the photo itself, with no paper around it. Useful for a picture that is
not a sheet of paper at all — a whiteboard, a serial number, a handwritten note — and with
the margin at 0 the page measures the photo exactly.
Orientation and margin
Automatic turns each page to match its own photo, so a landscape shot of a certificate and
a portrait shot of a receipt end up in the same PDF, each the right way round. Portrait or
landscape forces one shape throughout. The margin is in millimetres and defaults to 10 mm
on A4 and Letter — the border a printer needs — and 0 is allowed.
Limits and what happens to an iPhone photo
Room for a full document, and no surprises about the detail that ends up on the page.
30 images, 25 MB each, 100 MB in total
Thirty pages of a photographed document is a thick document already, and iPhone photos sit
well below the 25 MB per-image limit. Both numbers are checked while you add files: one
that is too heavy is named and skipped and the rest stay, and passing 100 MB in total stops
the intake with a message saying which limit was reached.
Nothing is upscaled
The pixels the camera recorded are the pixels that reach the page — a small or cropped
picture is never blown up with invented detail. On an A4 or Letter page a small photo may
be drawn up to 1.5× its natural size so it does not sit lost in the middle, and past that
it stays as it is.
Capped at 4000 px on the longest side
A 48 megapixel capture is scaled down to 4000 px before it goes in — across an A4 printable
width that is still over 500 dpi, far more than a photographed sheet of text can use. The
cap is what keeps a thirty-page PDF a file you can email instead of one that needs a file
transfer service.
Upright, single frame, one encode
iPhones usually store the sensor image plus a rotation flag; that flag is applied, so pages
arrive upright with the width and height to match. Only the main picture of a file is used:
the motion of a Live Photo, the depth map of a Portrait shot and the extra frames of a burst
do not go into the PDF, and the image is encoded once at high quality.
How to convert HEIC photos to PDF
Three steps, no account and nothing to install.
Add the photos
Drop the .heic files onto the box, click it to browse, or paste with Ctrl+V (Cmd+V on a
Mac). Photos pulled out of iCloud or a shared album behave exactly like ones taken on the
phone, and a file named .heif works too. Each one is checked against the limits as it
lands.
Order them and choose the paper
Use ↑ and ↓ to move a page, × to remove
one, then pick A4, US Letter or fit to image. Automatic orientation keeps every page the
right way round; set a margin in millimetres, or 0 to fill the sheet.
Download the PDF
The result card reports the page count and both weights, so a document that came out
heavier than expected is visible before you save. One click downloads the PDF, ready for an
email, a portal or a printer.
Three tips for photographing a document
The page in the PDF is only as good as the shot, and a clean shot takes ten seconds.
One sheet per photo
A photo that catches two pages becomes one page in the PDF, and the second sheet is then
cut in half. Put each sheet on its own, hold the phone parallel to it, and keep your shadow
out of the frame — the converter places the picture, it cannot straighten the perspective.
Do not hunt for more megapixels
Everything longer than 4000 px is scaled down anyway, so a 48 megapixel capture and a
12 megapixel one give the same page for a sheet of text. What does help is light and a flat
surface: contrast comes from the shot, never from the tool.
Sometimes a JPG is what is wanted
If a form asks for a picture rather than a document, HEIC to JPG
turns the photo into a file the whole world opens, and
compress the image if a size limit is in the way. A single
vector drawing, on the other hand, belongs on the
SVG to PDF page.
Frequently asked questions
Is this HEIC to PDF converter free?
Yes. There is no account, no payment, no watermark on the PDF and no cap on the number of documents you build. A short rate limit is the only restriction, and it keeps the service responsive for everybody.
How many iPhone photos can go into one PDF?
Up to 30 images, at most 25 MB each and 100 MB together. A typical iPhone photo is a few megabytes, so the page count is usually what stops a list first. The limits are checked while you add files: an oversized one is named and skipped while the others stay, and passing 30 images or 100 MB ends the intake with a message.
Is the text on the photographed pages searchable?
No. Each page is the photo you took, placed on a page, so the PDF contains images and no text layer: the words on a photographed contract cannot be selected, copied or found with the search box. Turning them into searchable text would need optical character recognition, which this converter does not do.
Does a Live Photo or Portrait mode photo keep its extras?
No — only the main picture is used. A HEIC can carry the short video of a Live Photo, the depth map Portrait mode recorded, several frames of a burst and a small thumbnail; a PDF page holds a single still image, so that extra material is simply not carried over. The picture itself keeps the look it had on the phone.
What happens to my files?
Files are processed on our server and not stored. The HEIC photos are decoded, turned upright, laid out and returned as one PDF; no account is involved and the download is the only copy that leaves the conversion.
