A 2 MB iPhone HEIC photo typically becomes 4 – 6 MB as JPG at quality 90.
Quality: Re-encoded once. Lossy → Lossy. At quality 90+, visual difference from the HEIC source is imperceptible.
Heads up: JPG doesn't support transparency, so transparent backgrounds in your HEIC will be flattened (usually to white).
Best for: sharing iPhone photos with non-Apple devices, embedding in documents, social media uploads.
Avoid when: you're staying within the Apple ecosystem (HEIC works natively on iOS/macOS and is half the file size).
Tip: HEIC is half the size of JPG at equivalent quality but isn't universally supported. Most non-Apple platforms — including older Windows, Android, web upload forms — still require JPG.
HEIC → JPG is the "share this iPhone photo with a Windows user / older email client / print lab" conversion. HEIC is the iPhone camera default since iOS 11, but Windows 10, many web forms, and older Android versions can't open it. Converting to JPG produces a ~2× larger file at equivalent quality (HEIC is that much more efficient) — worth it for compatibility.
JPG is the default format for photographs — 24-bit colour, lossy compression tuned for continuous-tone imagery, universally supported. Ubiquity is its main strength: government portals, e-commerce marketplaces, print labs, and CMS uploaders that don't say what format they want will accept JPG. The trade-offs: no transparency, no lossless option, compression artefacts around sharp edges (text, logos). Use JPG when the source is a photograph and the destination doesn't require a transparent background.
Your iPhone shoots HEIC using the HEVC (H.265) codec at 10-bit color depth. JPG uses an older DCT-based algorithm at 8-bit. During conversion, the decoder unpacks the HEVC-compressed data into a raw pixel buffer, tone-maps the 10-bit color values down to 8-bit (quantizing 1,024 levels per channel to 256), converts from the Display P3 color space to sRGB if needed, then re-encodes using JPG's Huffman + DCT pipeline. The result is a universally compatible file, typically 2-4× larger than the HEIC source at equivalent visual quality.
Convert HEIC to JPG when you need to share iPhone photos with Windows users, upload to platforms that reject HEIC (some job portals, government forms, older CMS systems), or import into software that doesn't support HEIC (Photoshop versions before 2020, many web-based editors). If the recipient has a modern Apple or Android device, you likely don't need to convert at all.
Technical comparison of the two formats — useful for deciding which to use, or for confirming what changes during conversion.

HEIC (High Efficiency Image Container) is a modern image format that Apple adopted as the default photo format starting with iOS 11 in 2017. It uses H.265/HEVC (High Efficiency Video Coding) compression to achieve dramatically smaller file sizes — typically 40-50% smaller than JPEG at equivalent visual quality. This efficiency allows smartphones to store significantly more photos without sacrificing the detail and colour accuracy users expect.
HEIC is primarily used within the Apple ecosystem for photos captured on iPhones and iPads. It supports advanced features including 10-bit colour depth, HDR imaging, and the ability to store multiple images (such as Live Photos or burst sequences) within a single file. The main drawback is limited compatibility outside of Apple devices — Windows requires an extension to view HEIC files, web browsers generally do not support it, and many image editors lack native HEIC support, making conversion to JPEG or PNG often necessary for sharing.
