Got HEIC photos from your iPhone that won’t open on a PC? Convert them to PDF with the free in-browser HEIC to PDF tool: add your photos, and they become clean PDF pages you can open and share anywhere, no special software required. It handles batch conversion, so several photos of a multi-page document become one tidy PDF, and it runs entirely in your browser, so private images like ID scans are never uploaded.
This guide explains what HEIC is, why Windows and many web apps can’t read it, how to convert single or multiple photos, the quality and file-size trade-offs, and how to do it all without exposing personal documents.
What is a HEIC file?
HEIC is the file extension Apple uses for photos saved in the HEIF container with HEVC (H.265) compression. Apple switched iPhones and iPads to it as the default photo format starting with iOS 11 in 2017. The reason is efficiency: HEIC stores an image at roughly half the size of an equivalent JPEG while keeping comparable quality. It also supports useful extras like storing multiple frames or depth data in one file.
On Apple devices, HEIC just works. The problem starts the moment a photo leaves the Apple ecosystem.
Why Windows and the web often can’t open HEIC
HEVC, the codec behind HEIC, relies on patented technology. Because of that licensing situation, support is not universal:
- Windows does not always open HEIC out of the box; it often needs a codec add-on installed first.
- Older Android phones and many older devices cannot read it.
- Lots of web apps and upload forms reject or fail to display HEIC.
So a photo that looks perfect on your iPhone can arrive as an unopenable file when you email it to a colleague on a PC, upload it to a government portal, or attach it to a web form. Converting to a universally supported format fixes this, and PDF is the most shareable target of all: it opens on every device, prints predictably, and bundles multiple images into one file. (If you specifically need image files rather than a document, JPG to PDF and PNG to PDF cover those formats once your photos are in a standard type.)
How to convert HEIC to PDF (step by step)
The HEIC to PDF tool runs in your browser, so there is nothing to install and nothing to upload.
- Open the tool. Go to HEIC to PDF in any modern browser, on desktop, Chromebook, phone, or tablet.
- Add your HEIC photos. Drag the
.heicfiles onto the page or tap to browse. You can add one or many. The tool decodes them locally and shows thumbnails. - Set the order. If you added several, drag the thumbnails into the right sequence. This matters for multi-page documents.
- Choose page settings. Pick a page size (A4, Letter, or auto-match the image) and orientation. Auto sizing makes each PDF page fit its photo with no white borders.
- Convert and download. Click convert and save the PDF. Each photo becomes one page, in your chosen order. Conversion takes a second or two per image.
That is the whole process. An Apple-only file is now a document anyone can open.
Batch converting many photos into one PDF
The most useful feature for real work is batch conversion. Say you photographed a five-page contract, or a stack of receipts for an expense report. Instead of sending five separate, possibly out-of-order image attachments, you:
- Add all the HEIC photos to HEIC to PDF at once.
- Drag the thumbnails so the pages are in the correct order.
- Set one page size that applies to every page for a consistent look.
- Download a single, ordered, multi-page PDF.
The result is one professional file instead of a scattered pile of images. There is no need to convert each photo individually and merge them later, though if you do end up with separate PDFs, Merge PDF can combine them.
Scanning documents with an iPhone, then converting
A very common reason people end up with HEIC files is using the iPhone as a scanner. Two approaches work well:
- Photograph each page. The iPhone saves them as HEIC by default. Add those files to HEIC to PDF, order them, and download one PDF, converting the Apple-only format into something universally readable in the same step.
- Use a proper scan workflow. For a true scan with edge detection, perspective correction, and contrast boosting, a dedicated phone-scanning tool gives cleaner pages because it squares up the document before conversion. Our guide on scanning documents with a phone camera walks through that approach, and the Scan PDF tool is built for it.
Either way, for the sharpest, most legible result:
- Shoot in good, even light with no harsh shadows.
- Hold the phone parallel to the page, not at an angle.
- Fill the frame with the document.
- Keep steady to avoid blur.
Quality and file size: what to expect
The conversion preserves the visual quality of your photos; the goal is for the PDF to look the same as the image did on your phone. The one thing that often changes is file size. HEIC’s HEVC compression is very space-efficient, and JPEG-style encoding inside a PDF is less so, which means the PDF can end up larger than the original .heic at similar visual quality.
For document scans, this is rarely a problem, legibility matters far more than a few extra kilobytes. But if the finished PDF is too big to email, run it through a compression tool afterward. Our guides on reducing PDF size for email and compressing without losing quality cover exactly that.
Why in-browser conversion keeps your documents private
Think about when people convert HEIC files. It is usually because they photographed something that has to be sent or filed, and very often that something is personal:
- A photo of an ID card, passport, or driver’s license for a verification form
- A bank statement or utility bill for proof of address
- A signed contract or agreement
- Medical paperwork or insurance documents
Uploading images like these to an unknown server is a genuine privacy risk. Many free HEIC converters do exactly that: your photos go to their infrastructure, get processed, and a copy may linger.
The HEIC to PDF tool avoids the problem entirely. Decoding and PDF generation happen in JavaScript inside your browser. The images are read from your device into local memory, converted, and offered for download. They never travel over the network, never land on a server, and disappear when you close the tab. No account, no watermark. Being able to turn an Apple-format photo of your ID into a shareable PDF without handing it to a third party is precisely the kind of task this in-browser approach is built for. For the broader case, see our overview of in-browser PDF tools with no upload.
Common use cases
- Sending iPhone photos to PC users. Convert so colleagues on Windows can actually open them.
- Document scans. Turn photographed contracts, receipts, or forms into one ordered PDF.
- Web and government forms. Many portals reject HEIC; a PDF (or standard image) sails through.
- Archiving. Store a stable, universally readable PDF instead of an Apple-specific format that future software may not support.
- Printing. A PDF prints at a fixed, predictable size, unlike phone photos that print at random scales.
Troubleshooting and limitations
- The file is rejected as not HEIC. iPhones sometimes save as HEIF with a
.heifextension, or as JPEG if you changed the camera setting. Check the actual file type; the tool handles HEIC/HEIF, and standard JPGs can go through JPG to PDF. - The PDF is larger than the original. Expected, because of the compression difference described above. Compress it afterward if needed.
- Pages are out of order. Reorder the thumbnails before converting; that is the moment to fix sequence.
- Photo is dark or skewed. Conversion does not fix a bad capture. Reshoot in better light and square to the page, or use a scan tool that corrects perspective.
- Stop iPhone saving HEIC at all. On the iPhone, Settings → Camera → Formats → Most Compatible switches the camera to JPEG, which avoids the issue for future photos, though you will still need to convert the HEIC files you already have.
Conclusion
HEIC is efficient, but it is an Apple-first format that Windows, older devices, and many web apps struggle to open. Converting to PDF makes your iPhone photos universally readable, keeps multi-page document scans in one ordered file, and gives you a print-ready document. The free HEIC to PDF tool does it in your browser, batch or single, with no signup and no watermark, and because everything runs locally, even photos of your ID or financial documents are never uploaded. That combination of convenience and privacy is exactly what you want when the photo is something personal.

Frequently asked questions
Open the heic-to-pdf tool in your browser, add one or more .heic photos from your iPhone, and the tool decodes them and lays them out as PDF pages. Set the page size and orientation, arrange the order if you added several, and download the PDF. It is completely free with no account and no watermark, and it runs entirely in your browser, so nothing is uploaded. This is the simplest way to make iPhone photos universally readable, because a HEIC file will not open on many Windows PCs or older devices, while a PDF opens everywhere. The conversion takes a second or two per image. Each photo becomes one page by default, so a handful of HEIC shots turns into a single tidy multi-page document you can email, print, or archive without anyone needing special software.
HEIC is the file extension for images stored in the HEIF container using HEVC (H.265) compression. Apple made it the default photo format on iPhone and iPad starting with iOS 11 in 2017 because it stores images at roughly half the size of JPEG with comparable quality. The catch is licensing and support. HEVC relies on patented codecs, so many Windows installations, older Android phones, and various web apps cannot open HEIC out of the box without an add-on. That is why a photo that looks fine on your iPhone arrives as an unopenable file when you send it to a colleague on a PC. Converting to PDF (or JPG) sidesteps the problem entirely, because those formats are supported universally and need no special codec to view.
Yes. The heic-to-pdf tool supports batch conversion: add as many HEIC files as you like, reorder them by dragging the thumbnails, and the tool combines them into a single multi-page PDF with one image per page. This is exactly what you want when you have photographed a multi-page document, for example several pages of a contract or a stack of receipts, and need them in one file and in the correct order. It is far tidier than sending a dozen separate image attachments that can arrive out of order or get separated. You set the page size once and it applies to all pages, so the resulting document looks consistent. If you only need one photo converted, the same tool handles a single file just as easily.
The conversion itself aims to preserve the visual quality of the original. HEIC uses efficient compression, and when the image is decoded and embedded into the PDF, the goal is to keep it looking the same as it did on your phone. What changes is the file format and often the file size, because JPEG-style encoding inside a PDF is less space-efficient than HEIC's HEVC compression, so the PDF can be larger than the original .heic even at similar visual quality. For document scans this is rarely an issue, since legibility matters more than file size. If the resulting PDF is too large to email, you can run it through a compression tool afterward to shrink it. For everyday photos and document captures, the quality difference is not noticeable.
You have two good options. The built-in route is to photograph each page; iPhone saves them as HEIC by default. Then add those HEIC files to the heic-to-pdf tool, put them in order, and download a single PDF, which converts the Apple-only format into something everyone can open. Alternatively, for a true document scan with edge detection and perspective correction, a dedicated phone-scanning workflow produces cleaner results because it squares up the page and boosts contrast before you ever convert. For best legibility, shoot in good even light, hold the phone parallel to the page, fill the frame with the document, and keep it steady. Whichever path you take, finishing in PDF gives you a portable, print-ready file rather than a loose pile of phone photos.
Only if the tool processes them locally. Many online converters upload your images to a server, which is a real concern when the photos are of an ID card, a passport, a bank statement, or a signed contract. The heic-to-pdf tool decodes and converts entirely in your browser, so the images never leave your device, never touch a server, and are gone when you close the tab. There is no account and no watermark. That privacy is the whole point for sensitive captures: people most often photograph documents precisely when those documents are personal or confidential. Being able to turn an Apple-format photo of your ID into a shareable PDF without exposing the image to a third party is exactly the kind of task in-browser conversion is built for.
