Why iPhone saves in HEIC and how to handle it
Since iOS 11 (2017), iPhone saves photos in HEIC (High Efficiency Image Container) by default. The reason is technical: HEIC compresses images at the same visual quality as JPG, but at 50% the size. In a 10 GB photo library, that means 5 GB of free space.
The downside: many older systems can't open HEIC. Web WhatsApp on PC, attaching to old email, résumé sites, Word — they often reject or display blank. The fix is converting to JPG, which is universally compatible.
How this converter works
Unlike iLovePDF, CloudConvert and similar, 4utils never sends your file to a server. The heic2any library runs 100% in your browser — only downloads when you first click (~150 KB) and stays cached. The photo only leaves your device if you choose to download the resulting JPG.
Benefits:
- Total privacy: intimate photo, document, screenshot — nothing goes to anyone's cloud
- No artificial limits: some sites cap at 5 conversions/day. Here it's unlimited.
- No signup/login: just drop and download
- Works offline: after first load, the entire page works without internet
JPG or PNG — which to choose
JPG (default) is smaller and perfect for everyday photos: sharing, attaching, social media. There's minimal compression loss but the human eye usually doesn't notice.
PNG is lossless: no pixel altered. Result is larger (3-5× the JPG) but ideal for: high-resolution printing, editing later (PNG keeps alpha channels), screenshots with text.
Frequently asked questions
Why does iPhone save in HEIC?
HEIC is the iOS 11+ default because it compresses images at ~50% the size of JPG keeping quality. Many older systems (web WhatsApp, Word, upload sites) don't open it directly, so converting to JPG fixes it.
Does the photo leave my computer?
No. Conversion runs 100% in your browser via JavaScript (heic2any). File never leaves the device — no upload, no tracking.
Can I convert multiple files?
One file at a time for now (client-side limit). For large batches, convert one at a time — result is identical.
Why does it take a few seconds?
First conversion downloads heic2any lib (~150 KB) from CDN. Then cached. Conversion uses your CPU — 2-5 seconds for typical photos.
Does it work on phones?
Yes — iPhone, Android, mobile Chrome. Tap to pick a file (no drag-drop on mobile).
