HEIC read on your device
The photos are decoded by your browser, or by a decoder FileGizmo ships with the page, so no photo is sent anywhere to be converted.

Turn iPhone photos into one document without sending them away
iPhones save photos as HEIC by default, and that is the reason a photographed form so often fails to upload: the portal, the email system or the older computer at the other end does not know the format. A PDF is the file everyone can open, and it can hold several photos as separate pages. This page takes HEIC and HEIF photos and makes one PDF from them.
Each photo is decoded once. Safari reads HEIC natively, so the work is quick there. In other browsers a small decoder that ships with FileGizmo does the reading, in a worker on the same site, so the photo still does not leave your device. The decoded picture is placed in the PDF as a lossless image. No second round of lossy compression is applied, which keeps small print in a photographed document readable.
The trade is size. HEIC stores a photo in roughly half the space of a JPG, and a lossless copy inside a PDF takes more room than either. A dozen phone photos can produce a PDF of tens of megabytes. If a portal sets a limit, make the PDF first, then run it through Compress PDF and check that the text is still legible.
Page order and size
Photos appear in the order you chose them. Drag a card to move it, or focus a card and use the arrow keys, and the new position is read out to screen readers. Remove a photo you do not want before you create the PDF.
Every page has the shape of its photo. Nothing is cropped to A4 or Letter and nothing is stretched. A tall phone photo becomes a tall page. The orientation your phone recorded is applied first, so a photo you took upright is an upright page.
Taking the photos
For a document, work in good light and hold the phone flat above the page so the paper fills the frame. Take each page as its own photo, and choose them all here in one go. If you photograph a page at an angle, its text is harder to read in the PDF, and no conversion recovers it afterwards.
Nothing leaves the device
The photos are read in your browser and the PDF is built in a local worker. There is no account, no queue on a server and no copy kept anywhere else. The PDF is offered as a download from your own device, and closing the tab discards the working copy.
To turn a single HEIC photo into a JPG instead, use HEIC to JPG.

Everything you need
Page order you control
Reorder the photos with drag and drop or the keyboard before the PDF is made, so a multi-page scan comes out in reading order.
Portrait stays portrait
Each page matches its photo, and the rotation your phone recorded is applied, so an upright shot is an upright page.
Nothing is uploaded, and you can verify it
Processing runs on this device. Open the browser’s Network panel while the tool works and you will see no file upload request to FileGizmo. Temporary previews use local browser URLs, and closing or resetting the page releases them instead of leaving a server copy behind.
No limits, no watermarks
Use the tool without a daily task counter, account wall, output watermark, or artificial upload cap. FileGizmo does not meter a transfer it never receives. Available memory, processor speed, browser canvas limits, and the file format itself set the practical limit.
Works on any device, and offline after first load
Use a current browser on desktop, Android, iPhone, or iPad without installing an app. Once this tool and its required assets load, the cached workflow works without a connection. Large jobs are usually more comfortable on a desktop with additional memory.
Frequently asked questions
Why convert HEIC to PDF instead of sharing the photos?
Many forms, portals and email systems do not open HEIC files at all. A PDF opens everywhere, and several photos become one file that keeps its page order.
Is the picture quality reduced?
The HEIC photo is decoded once and placed in the PDF as a lossless PNG, so the page shows the photo as your phone recorded it. The PDF is usually larger than the HEIC files, because HEIC is a much tighter format.
Can I mix HEIC photos with JPG or PNG images?
Yes. Choose them together and set the order. Each one becomes its own page, and each page takes the size of its photo.
Are my photos uploaded?
No. FileGizmo decodes the photos and builds the PDF inside your browser, on your device. Nothing is sent to FileGizmo or to any other service.
