Why government, HR and insurance forms reject HEIC — and how to submit JPEG or PDF from this tool
Updated
The HEIC files and any JPEG or PDF you download are built on this device. This site does not receive the photos. There is no account.
A council portal, a right-to-work upload, an insurer’s claim
form, or a recruiter’s HR system will often take a photograph
of a document — and then refuse the file the iPhone just
saved. The error is rarely about the picture. It is about the
extension. Those systems were written when “a photo” meant
.jpg or .pdf. HEIC never made the
allowlist. Renaming the file does not change the bytes. You
need a real JPEG or a real PDF.
Why the rejection is so common
Government and insurance software is conservative on purpose.
An upload box that accepts “any image” is a support queue
waiting to happen, so contractors ship a short list:
JPEG, sometimes PNG, sometimes PDF. HEIC is not on that list
because Windows servers, old antivirus scanners, and the
people who wrote the validation in 2014 do not treat it as a
photograph. The check is often as crude as “does the name end
in .jpg, .jpeg or
.pdf?”. A perfectly sharp iPhone still still
fails.
HR portals add another habit: they want one attachment per question. Three HEIC files of a passport — cover, photo page, address — become a problem even after you convert, unless you make one PDF. Insurance claims want a damaged bumper and a registration plate in a single pack. None of that is a reason to upload the originals to a stranger’s converter. The copy can be made here, then you attach it yourself.
There is a second, honest failure mode that conversion will not fix. If the portal says the file is too large, the problem is megabytes, not HEIC. A full-resolution still can be several megabytes as JPEG. If the photo is blurry, cropped wrong, or of the wrong document, a different format will not help. Read the rejection. Format and size are different sentences.
Make the file the form asked for
- Check the portal’s own wording. JPEG, JPG, PNG, or PDF — pick that, not what is convenient.
-
Open the converter and drop the
.heicor.heifstills. Wait until each card has a thumbnail. - For an image upload, download JPEG (or PNG if they named PNG). For one attachment, tick Include in PDF on the pages they asked for and download the PDF.
- Attach that downloaded file on the portal. This site never submits anything on your behalf.
JPEG or PDF
Use JPEG when the box says “photo”, “image”, or lists
.jpg. The quality slider defaults to 92%, which
is enough for a document photo you can still read. If the
portal has a small size cap, lower the slider and add the
HEIC again. The slider does not rewrite cards already in the
list. The
Windows JPEG guide
covers batching on a PC; the same buttons work on any
current browser, including
Android.
Use the PDF when they asked for one file, or when a human will print the pack. Each selected still becomes an A4 page. Landscape photos get a landscape page. There is no OCR and no text layer, so a photographed letter is not searchable. Most claims teams only need to read it. If they asked for a “searchable PDF”, this is the wrong tool — scan with Notes on the iPhone instead. The PDF guide has page order and when a scanner app is the better first step.
PNG is the odd one out. A few older HR systems and some print shops name it. A PNG of a photograph is usually larger than the JPEG. Use it when they named it. Details are on the PNG guide.
Identity, address and insurance photos
Passport and driving-licence shots are ordinary camera stills to this converter. They are sensitive to you. Because decode happens in the tab, the photo does not travel to this site’s servers. Ordinary page requests for HTML and the decoder still appear in hosting logs, like any website; those are program files, not the picture. The privacy page says this in full. Do not email the photo to hello@heicondevice.com if something fails — describe the error instead.
The JPEG and PNG this tool writes do not keep EXIF. Capture time and GPS are stripped because the copy is re-encoded from pixels. For a claim form that should not receive your home coordinates, that is usually a benefit. Keep the HEIC original if you later need the metadata. For Live Photo motion, which is omitted, see Live Photos, bursts and panoramas.
If it still fails
-
Wrong extension. Confirm the download
really ends in
.jpgor.pdf. Some phones open a preview and you accidentally re-share the HEIC. - Size cap. Fewer pages, or a lower JPEG quality, then convert again.
- They wanted a scan, not a photo. Conversion cannot straighten a desk or boost contrast. Use the iPhone’s document scanner in Notes, then attach that PDF.
- They wanted the original camera file. Rare, but if a solicitor asks for the HEIC, send the HEIC. This tool only makes copies.
None of this changes the iPhone’s default. New shots will still be HEIC until you set Camera → Formats → Most Compatible, which is explained in why iPhone photos are HEIC. That setting is for tomorrow. Today’s rejected upload needs a JPEG or PDF copy of the files you already have.
