The fastest free fix is to change one iPhone setting so your photos stop being HEIC in the first place, and for files you already have, use a browser-based converter like OpenHEIC or FreeConvert, both work without an account, a card, or software installs. These tools run entirely in your web browser, so they work on any computer, phone, or tablet with internet access. For the actual conversion, you drag the HEIC file onto the page, wait a few seconds, and download the JPG that comes out.
Why Your PC Won't Open iPhone Photos
Windows does not natively support Apple's HEIC/HEIF image format, which is why double-clicking an iPhone photo often shows an error or a blank preview. Apple documents that you can change this behavior at the source: in Settings > Camera > Formats, set the option to "Most Compatible" so new photos save as JPG instead of HEIC. For photos you already have, Apple also gives you the choice to keep originals or convert them to JPEG when transferring to a PC, this appears as a prompt when you plug in your iPhone and select "Import" in Windows.
The Three Ways to Fix It Right Now
1. Change Your iPhone Camera Settings (Prevents Future Problems)
On your iPhone, go to Settings > Camera > Formats and select "Most Compatible". This makes every new photo save as a JPG, which Windows opens without issue. Apple also offers a separate transfer setting: when you plug your iPhone into a PC, you can choose "Keep Originals" or "Convert to JPEG", pick the latter for files you're moving to a Windows machine. This is the only permanent fix, because it stops the problem at the source rather than requiring conversion every time.
2. Use a Browser-Based Converter (For Files You Already Have)
If you have HEIC files sitting on your phone or PC, these free web tools convert them in seconds without installing anything. Each one runs in your browser, so it works on any operating system, and none of them require an account or a credit card. The trade-off is that some upload your file to their servers, so for sensitive images, pick one that processes locally.
- OpenHEIC, Free, unlimited, and runs entirely in your browser with no uploads. It uses your computer's processing power, so your photos never leave your device. Best for privacy-conscious users.
- FreeConvert, Free HEIC to JPG conversion in any browser, and the site deletes your uploads automatically after 8 hours. Good for quick, one-off conversions where you don't mind a temporary upload.
- HEIC.online, Free drag-and-drop converter that also lets you save the output directly to cloud storage like Google Drive or Dropbox. Handy if you want the JPG to go straight to your cloud.
- HEICVault, Free, private, unlimited browser conversion with no signup. Similar to OpenHEIC but with a slightly different interface. Works fine for occasional use.
- OpenMyHEIC, Free browser tools with no download, no account, no signup, and no watermarks. Simple and straightforward, but the site has ads.
- HEIC.dev, 100% free with no hidden fees, watermarks, or registration. A clean, minimal interface that does exactly one thing.
- Adobe Express, Free converter from Adobe, available from your iPhone or any web browser. It's a solid choice if you already use Adobe products, but the free tier may have file size limits.
- Canva, Free HEIC to JPG converter on the web, Mac desktop app, and iOS app. If you already use Canva for design, this is convenient, but it's overkill for a single photo.
- PDF24 Tools, Free online conversion in the browser with no limits. It's part of a larger suite of PDF tools, but the HEIC converter works just as well as the standalone sites.
3. Use a Desktop App (For Batch Conversion or Offline Work)
If you have hundreds of HEIC files, browser tabs get tedious. Free, open-source desktop software handles bulk conversion offline, and none of them require an account or payment. These are the most powerful options, but they require a download.
- GIMP, Free, open-source image editor that opens HEIC files (on some systems) and can export them as JPG. Overkill for a single conversion, but perfect if you need to edit the photo anyway.
- Inkscape, Free vector graphics editor that can also handle raster images. Not the first tool for HEIC conversion, but it works if you're already using it.
- ImageMagick, Free, open-source command-line tool that converts HEIC to JPG in bulk. Powerful but requires using the terminal. Best for tech-savvy users who want automation.
- Squoosh, Free, open-source image compressor from Google that runs entirely in your browser. It supports HEIC input and lets you adjust JPG quality before downloading. A good middle ground between web tools and desktop apps.
What Most People Get Wrong About This
The biggest mistake is assuming you need to pay for a converter or install sketchy software. Every legitimate free option is either a browser tab or a setting on your phone. The second mistake is not changing the iPhone camera format first, if you convert one photo but keep shooting in HEIC, you'll be back here next week. Third, people forget that Apple's own transfer settings can auto-convert to JPEG when you plug your phone into a PC, so you don't even need a third-party tool for new transfers.
What to Check Before You Commit to a Converter
Before you upload a personal photo to any website, ask these three questions. First, does the site process the file locally or upload it? OpenHEIC and HEICVault process locally; FreeConvert uploads but deletes after 8 hours. Second, are there file size or count limits? Most free tiers cap you at 50-100 MB or a certain number of images per batch. Third, does the site work in your country? None of the pages document country restrictions, but some services are geo-blocked, so if a site doesn't load, try another one from the list above.
How to Stop This Problem From Ever Happening Again
Set your iPhone to "Most Compatible" in Settings > Camera > Formats. That's it. Every new photo will be a JPG, and Windows will open it without a second thought. If you also use iCloud, go to Settings > Photos and select "Keep Originals" to avoid automatic HEIC conversion on your phone. For files you transfer to a PC, choose "Convert to JPEG" when Windows asks how to import them. This takes ten seconds and prevents the issue permanently.
Frequently Asked Questions
Will converting HEIC to JPG reduce the photo quality?
Yes, slightly. HEIC compresses photos more efficiently than JPG, so converting to JPG creates a larger file with the same visible quality. For most people, the difference is invisible on a phone screen or a standard monitor. If you need lossless quality, keep the original HEIC file as well.
Can I convert HEIC to JPG on my iPhone without a computer?
Yes. Open the photo in the Photos app, tap the Share button, and choose "Save to Files", this saves a copy in the original format. To get a JPG, use a shortcut like "Convert HEIC to JPG" from the Shortcuts app, or use a free iOS app like GadgetHacks (which lists several free converters). The simplest method is to email the photo to yourself and choose "JPG" when asked for the format.
Is it safe to upload my HEIC photos to a free converter website?
It depends on the site. Services like OpenHEIC and HEICVault process files locally, so your photos never leave your device. Others upload to their servers, which is a risk if the photo is sensitive. For private images, use a local converter or change your iPhone settings to avoid HEIC altogether.
Do I need to install anything to convert HEIC to JPG?
No. All the browser-based tools listed above work without installation. If you prefer a desktop app, GIMP and ImageMagick are free downloads, but they're not required for a single conversion. The quickest path is a browser tab.
What if the converter asks for my email or a credit card?
That's a red flag. Legitimate free converters don't ask for either. If a site demands an account or payment, close the tab and use one of the services listed here. None of the recommended tools require a card, and only Canva requires a free account, but you can skip it and use the others.
Do it here, free and with nothing to install: Heic.now, Jpg.now.
