HEIC to JPG: Get iPhone Photos Into a Format That Opens Everywhere

I tried to upload iPhone photos to a property listing site after viewing a flat. The uploader rejected every file — it accepted JPG and PNG only. My photos were all .heic. The conversion took three minutes in a browser tab and the upload went through without issues. The estate agent had never heard of HEIC either, which suggested the problem was common.

The HEIC to JPG converter processes photos locally in your browser. Nothing gets sent to a server.

Why Apple Uses HEIC and Why It Causes Problems Elsewhere

Apple introduced HEIC (High Efficiency Image Container) as the default iPhone camera format with iOS 11 in 2017. The motivation was storage efficiency: HEIC achieves roughly the same visual quality as JPEG at about half the file size, using HEVC compression (H.265). On a phone taking dozens of high-resolution photos daily, that 50% saving is meaningful over months of use.

The problem is that HEIC requires dedicated codec support from every piece of software that needs to open it. Apple's own ecosystem handles it natively across iOS, macOS, and iPadOS. Outside that ecosystem, support is inconsistent and often absent. Windows requires a separately installed codec pack many systems do not have. Older Android devices cannot open HEIC. Most email clients do not preview it inline. Most web upload portals reject it. Many professional tools, particularly older versions, do not recognise the format. JPEG has had support in everything for thirty years without exception.

Standard vs Optimized Quality

Standard mode produces JPEG output at 90% quality — sharp, compact files appropriate for sharing by email, uploading to websites, and posting to social media. The files are noticeably smaller than Optimized output while looking identical at normal screen viewing sizes.

Optimized mode uses 95% quality and is worth choosing for photos that will be printed at large sizes or used in professional publications. File size at Optimized is roughly 50% larger than Standard. At typical display sizes on screen, the visual difference between Standard and Optimized is imperceptible. Choose based on the intended use, not a default assumption that higher is always better.

AI Background Removal

Enable AI background removal to produce a JPEG with the subject isolated against a plain white background. This is useful for product photos submitted to e-commerce platforms, profile images for professional directories, and any image where a clean neutral background is required without manual editing. The algorithm performs well for subjects with clearly defined edges against a contrasting background — people, products, vehicles, objects with distinct outlines. Complex subjects with fine edge detail such as loose hair, transparent objects, or subjects that blend into the background may require manual refinement after the initial removal.

Custom Dimensions

Set a target width or height before converting to get JPEG output at specific pixel dimensions. Aspect ratio is maintained automatically when only one dimension is specified. Use this to produce photos at the exact dimensions required by a platform upload specification — many social media platforms, listing sites, and CMS image fields have specific pixel dimension requirements this saves you from needing an image editor to meet.

How iPhone Photos Work: Resolution and Metadata

iPhone photos at full resolution are typically 12 megapixels (4032 × 3024 px) on standard models, 48 megapixels on Pro models in full resolution mode. HEIC files include EXIF metadata: GPS coordinates, timestamp, camera model, lens focal length, and exposure settings. The converter preserves the image pixel data during conversion. Browser-based converters typically strip GPS coordinates, which is generally desirable for privacy when sharing photos publicly.

Frequently Asked Questions

Why does my platform not accept HEIC files?

HEIC is an Apple format that requires dedicated codec support. Most platforms, upload forms, email clients, and software not explicitly updated to handle it will reject or fail to preview HEIC files. Converting to JPEG makes the photos accepted by everything without exception.

Will quality suffer in the conversion?

At Standard quality (90%), the output JPEG is visually indistinguishable from the source photo at normal viewing sizes. Optimized quality (95%) preserves more fine detail for large prints. The conversion does not introduce new artefacts — it encodes the existing pixel data at the quality level you select.

Are my photos uploaded to a server?

No. Conversion happens entirely in your browser using client-side JavaScript. Your photos never leave your device. No file is transmitted to any server at any point during the conversion or download.
