If you use an iPhone you have probably come across files ending in .heic that do not open on a Windows computer, cannot be uploaded to a form or do not show in an email. It is not a bug: it is a modern format that not every program recognises. Here you will understand why it exists and how to convert it without hassle.
What HEIC is
HEIC is Apple's variant of HEIF, an efficient image standard. Since iOS 11, iPhones save photos in this format by default because it achieves quality similar to JPG at roughly half the weight. It also supports advanced features such as depth, live photos and wider colours.
The result is that a gallery with thousands of photos takes noticeably less space on the phone, which is very valuable when storage is limited.
Why it causes problems outside the iPhone
Most web platforms, printers, procedure portals and older programs only recognise JPG and PNG. When you try to upload a HEIC file, the system answers 'invalid format' or simply does not show the image. On Windows, opening HEIC may require additional extensions that are not always installed.
That is why, before sending a photo to someone or uploading it to a portal, it is wise to convert it to JPG, which opens practically anywhere.
Converting HEIC to JPG with Zipnify
Open the HEIC to JPG page, select your photos or drag them in, choose the quality and download the results. If you need to keep transparency or avoid further loss, there is also a HEIC to PNG option, although the file will weigh more.
Conversion happens inside your browser. Your personal photos do not travel to any server, something you will value especially with images of documents, family or work.
iPhone settings to avoid the problem
If you prefer your phone to save directly as JPG, go to Settings, Camera, Formats and choose 'Most Compatible'. New photos will be saved as JPG, although they will take more space. You can also keep HEIC and convert only when you need to.
When sharing by email or messaging, the iPhone often converts automatically to JPG, but when transferring by cable or uploading from the gallery it may keep the original format.
Quality and weight after conversion
When going from HEIC to JPG, the file usually grows because JPG is less efficient. At quality 85 to 90 the visual difference is minimal. If the resulting JPG is too heavy for your destination, you can reduce it afterwards with the image compression tool or the exact size tool.
Live photos are converted as a still image, and extra information from the original format, such as depth, is not kept in the JPG.
Final tips
Always convert a copy and keep the original HEIC, which retains more information. If you will convert many photos, process them in batches to save time. And check that the orientation of the resulting images is correct before sending them.
If you work with documents, combine the conversion with the images to PDF tool to present everything in a single file.
