How to convert HEIC to JPG
- Drop your
.heicor.heifphotos onto the box — one or a whole batch. - Choose JPG (or PNG / WebP), a quality, and optionally a smaller maximum size.
- Click Convert, then download each photo or all at once.
Unlike most HEIC converters, nothing is uploaded: the decoding is done by a WebAssembly build of libheif running in your browser. The decoder (about 1.5 MB) loads the first time you convert and is cached after that.
Why HEIC causes trouble
Apple adopted HEIC in 2017 because it halves storage without visible loss. Support elsewhere has lagged: Windows needs a paid HEIF extension, many web forms and CMSs reject it, older photo editors can’t open it, and emailing a HEIC to a non-Apple user often produces a “can’t open file” reply. JPG, by contrast, opens everywhere.
Which format to choose
| Format | Use it for | Size vs HEIC |
|---|---|---|
| JPG | Sharing, uploading, printing, email — anywhere compatibility matters | ~1.5–2× larger |
| PNG | When you need lossless quality or transparency (rare for photos) | 5–10× larger |
| WebP | Websites; smallest files, supported by all modern browsers | About the same |
At quality 90, JPG output of a 12-megapixel iPhone photo is typically 3–5 MB. Set Max dimension to 1920 px for a version that’s a fraction of the size and still looks sharp on any screen.
Other things to know
- Orientation — HEIC stores rotation as metadata; the converter applies it, so photos come out the right way up.
- Live Photos — only the still frame is converted; the short video isn’t part of the image file.
- Burst / multi-image HEIC — the first image in the container is used.
- Metadata — EXIF data (camera, date, location) is not copied to the output. For sharing that’s usually a benefit.
- Safari can display HEIC natively, so on a Mac or iPhone the decoder isn’t even needed.
Need the other direction, or a different format? The image converter handles JPG, PNG and WebP; the compressor and resizer accept HEIC directly too.
Frequently asked questions
What is a HEIC file?
HEIC (High Efficiency Image Container) is the format iPhones and iPads have used by default since iOS 11. It stores photos at about half the size of JPG with the same quality, but many websites, Windows apps and older programs can't open it — hence the need to convert.
Does converting lose quality?
HEIC is already compressed, so converting is a re-encode. At quality 90 the difference is invisible; choose PNG for a lossless copy (much larger files). Resolution is kept unless you set a max dimension.
Are my photos uploaded?
No. The HEIC decoder (libheif, compiled to WebAssembly) runs inside your browser. Photos never leave your device — you can confirm by disconnecting from the internet after the decoder has loaded.
How do I stop my iPhone saving HEIC in the first place?
Settings → Camera → Formats → choose Most Compatible for JPG. Or leave HEIC on (it saves space) and use Settings → Photos → Transfer to Mac or PC → Automatic, which converts on transfer.
