What is HEIC to JPG?
HEIC (High Efficiency Image Container) is the default image format used by Apple since iOS 11. Compared to JPG, it can save about 50% storage space while maintaining the same or better image quality. However, HEIC format is incompatible with many devices and platforms, especially Windows computers, Android devices, and some older software. Therefore, converting HEIC to JPG is a must-have for iPhone users. Our tool uses browser-side Canvas API for format conversion, all processing is done locally and never uploaded to servers. Supports batch conversion, can process multiple HEIC files at once.

FAQ
What is HEIC format?
HEIC (High Efficiency Image Container) is an image format developed by Apple, becoming the default camera format for iPhone since iOS 11. It uses HEVC (H.265) video encoding technology to compress images, saving about 50% storage space compared to JPG while maintaining the same or better image quality. HEIC also supports advanced features like transparency, depth maps, multiple images. However, HEIC is incompatible with many platforms and devices, so it needs to be converted to the more universal JPG format.
Will image quality decrease after conversion?
Image quality after conversion depends on your quality setting. Default quality (90%) is nearly lossless, no visible difference to the naked eye. At 100% quality, JPG file size increases but quality is best. Recommend choosing based on use: 70-80% for web sharing, 90-100% for printing, 100% for archiving. Our tool uses high-quality Canvas API for conversion, ensuring best image quality.
How many files can be batch converted?
Theoretically no limit, you can select any number of HEIC files at once. Practical limits depend on device memory and browser performance. Recommend converting no more than 100 files at once for best experience. Large files (over 10MB) use more memory, recommend processing in batches. All files are processed locally in the browser, never uploaded to servers.
How fast is the conversion?
Conversion speed is very fast, typically only a few seconds per file. 12MP iPhone photos take about 1-3 seconds to convert. During batch conversion, all files are processed sequentially, total time depends on file count and size. Using modern browsers (Chrome, Firefox, Safari, Edge) provides best performance. Processing speed is mainly affected by device CPU performance.
Is my data safe?
Completely safe. All conversions happen locally in your browser using Canvas API technology. HEIC files are never uploaded to any servers, no data leak risk. After closing the page, all processing data is automatically cleared. Suitable for processing private photos and important files. Our tool does not collect, store or transmit any of your file data.
Pro Tips
💡 For web sharing, recommend using 70-80% quality, can significantly reduce file size while maintaining good image quality. For printing or archiving, use 90-100% quality. When batch converting, recommend converting a few files first to test the effect, then batch process after confirming satisfaction. If conversion is slow, try closing other browser tabs to free up memory.
