使用指南
iPhone photos not opening on Windows? iOS shoots HEIC by default (half the size of JPG), which Windows and many apps do not recognize. This tool converts HEIC to JPG entirely in your browser — photos never leave your device, the core difference from most online converters.
1. Convert in three steps
- Drop HEIC photos into the upload zone (dozens at a time supported).
- Confirm quality (90% default, visually near-lossless) and click Convert.
- Download individually or all at once — original filenames are kept with a .jpg extension.
2. Choosing between HEIC, JPG and PNG
HEIC is the Apple efficient format: great quality, small size, poor compatibility — fine inside the Apple ecosystem. JPG is universal: every device and app reads it, right for sharing, uploads and office use. PNG is lossless but heavy: for editing or transparency. For daily "send it to someone" choose JPG; for "keep original quality" choose PNG (a HEIC to PNG tool is also on this site).
3. Two common questions
- Files got bigger after conversion: expected — HEIC compresses better than JPG at equal quality. 90% is the size/quality balance; drop to 80% for smaller files.
- Tired of converting every time: switch iPhone Settings - Camera - Formats to "Most Compatible" to shoot JPG directly (at the cost of doubled photo size).
FAQ
Re-encoding has a minor effect; the default 90% quality is visually near-lossless. For fully lossless output use the HEIC to PNG tool.
No. This tool decodes HEIC and converts it locally via WebAssembly in your browser — photos never leave your device, which is the core difference from most online converters.
Since iOS 11, iPhones default to HEIC (High Efficiency), roughly half the size of JPG. Windows and some apps do not support it, hence the frequent need to convert. You can also switch Settings - Camera - Formats to "Most Compatible" to shoot JPG directly.
Yes. Drop dozens of photos at once, then download individually or all together.
