How to Use
- 1Upload one or more HEIC or HEIF files by clicking the upload area or dragging and dropping from your file manager. You can select multiple files at once for batch conversion. The tool accepts both .heic and .heif extensions.
- 2Adjust the JPG quality slider to control the output file size and detail level. The slider ranges from 0% (maximum compression, smallest file, most artifacts) to 100% (minimum compression, largest file, best quality). A setting of 85-90% is recommended for most use cases.
- 3Click 'Convert to JPG' to begin the browser-based conversion. Each file is decoded from the HEVC-encoded HEIC container and re-encoded as a standard JPEG using the Canvas API. A progress indicator shows the status for batch conversions.
- 4Preview each converted image directly in the browser to verify quality before downloading. The preview shows the output at actual resolution so you can check for any quality loss, especially in areas with fine detail or subtle gradients.
- 5Download each converted JPG individually by clicking its download button. The output filename preserves the original name with a .jpg extension, making it easy to identify and organize your converted photos.
- 6For additional files, simply add more HEIC images to the queue without refreshing the page. Previous conversions remain available for download until you clear the session or close the tab.
About HEIC to JPG Converter
The HEIC to JPG Converter transforms iPhone and iPad photos from Apple's HEIC/HEIF format into universally compatible JPG files. HEIC (High Efficiency Image Container) is a file format based on the HEIF (High Efficiency Image Format) standard defined in ISO/IEC 23008-12. It uses HEVC (H.265) compression for still images, achieving roughly 50% better compression than JPEG at equivalent visual quality. Apple adopted HEIC as the default photo format starting with iOS 11 in 2017, which is why every modern iPhone and iPad produces .heic files by default.
Despite its technical superiority, HEIC remains poorly supported outside the Apple ecosystem. Windows 10/11 requires a paid HEVC codec extension from the Microsoft Store to open HEIC files natively. Many Android devices cannot display HEIC images without third-party apps. Web browsers have limited HEIC support — only Safari handles it natively, while Chrome and Firefox require the image to be decoded before display. Email clients, social media upload forms, printing services, and many content management systems still expect JPEG or PNG input.
This converter bridges the compatibility gap by decoding HEIC files entirely in your browser and re-encoding them as standard JPEG. The decoded pixel data is drawn onto an HTML5 Canvas element, then exported using canvas.toBlob() with the image/jpeg MIME type and your chosen quality parameter. This approach produces fully standard JPEG files that work everywhere — Windows, Android, Linux, web browsers, email attachments, photo printing services, and any application that accepts images.
The quality slider controls JPEG's DCT-based quantization, which determines how much high-frequency detail is preserved versus discarded. At 85-90%, the output is visually indistinguishable from the HEIC original for most photographs, with file sizes comparable to what the iPhone would have produced in JPEG mode. At 95%+, you get near-lossless output suitable for archiving or print production, though file sizes will be significantly larger than the original HEIC. At 70-80%, you achieve aggressive compression suitable for email attachments and quick sharing.
Batch conversion support is essential because HEIC compatibility issues typically affect entire photo libraries, not individual files. When you transfer iPhone photos to a Windows computer via USB, AirDrop to a non-Apple device, or download iCloud photos on Android, you often end up with dozens or hundreds of HEIC files that need conversion. This tool handles multiple files in a single session, processing them sequentially and keeping all results available for download.
All conversion runs entirely in your browser with no server communication. Your photos are never uploaded, transmitted, or stored anywhere outside your device. This is particularly important for personal photographs, which may contain sensitive EXIF metadata including GPS coordinates, timestamps, and camera information. The privacy-first design makes this tool safe for converting family photos, medical images, legal documentation, and any other confidential visual material.
Frequently Asked Questions
Why do iPhones use HEIC instead of JPG?
Apple adopted HEIC starting with iOS 11 because it uses HEVC (H.265) compression, which achieves approximately 50% smaller file sizes than JPEG at equivalent visual quality. This saves significant storage space on your device — a typical iPhone photo takes about 1.5-2 MB in HEIC versus 3-4 MB in JPEG. Apple prioritized storage efficiency since iPhones have fixed, non-expandable storage. You can change your iPhone to shoot in JPEG via Settings > Camera > Formats > Most Compatible.
Can I batch convert multiple HEIC files at once?
Yes. Select multiple HEIC or HEIF files from your file picker, or drag and drop a group of files into the upload area. All files are queued and converted sequentially. Each converted JPG is available for individual download as soon as its conversion completes. There is no hard file count limit, but very large batches may take longer depending on your device's processing power.
What quality setting should I use for the conversion?
For general sharing and everyday use, 85-90% produces files that look identical to the original with reasonable file sizes. For print production, archiving, or professional photography workflows, use 95% or higher to minimize any quality loss from the re-encoding. For email attachments or quick sharing where file size is more important than detail, 70-80% works well. The preview panel lets you verify the result before downloading.
Are my photos uploaded to a server during conversion?
No. The entire conversion process runs locally in your browser using JavaScript. The HEIC file is decoded in memory on your device, the pixel data is drawn to a Canvas element, and the JPEG output is generated using the Canvas API. No network requests are made at any point during the process. Your photos remain on your device at all times, making this tool safe for private and sensitive images.
Does the converter work on Windows and Android devices?
Yes. The converter runs in any modern web browser — Chrome, Edge, Firefox, and Safari — on Windows, macOS, Linux, Android, and iOS. No app installation, browser extension, or codec download is required. This is especially useful on Windows, where opening HEIC files natively requires purchasing the HEVC Video Extensions from the Microsoft Store.
Does the conversion preserve EXIF metadata like GPS and camera settings?
No. The Canvas API used for the conversion does not transfer EXIF metadata from the source file to the output JPEG. This means GPS coordinates, camera settings, timestamps, and other metadata are stripped during conversion. For many users this is actually a privacy benefit, as it removes location data from photos before sharing. If you need to preserve metadata, consider using a desktop application like ImageMagick or the iOS Files app export feature.
What is the difference between HEIC and HEIF?
HEIF (High Efficiency Image Format) is the broader standard defined in ISO/IEC 23008-12 that specifies a container for images compressed with various codecs. HEIC (High Efficiency Image Container) is the specific implementation that uses HEVC (H.265) for compression — this is what Apple uses. The file extensions .heic and .heif are often used interchangeably, and this converter handles both. Some cameras and devices may produce .heif files with different internal codecs, but the most common variant by far is Apple's HEVC-based HEIC.
How can I stop my iPhone from taking photos in HEIC format?
Go to Settings > Camera > Formats and select 'Most Compatible.' This switches your iPhone to capture photos in JPEG and videos in H.264 instead of HEIC and HEVC. Note that this will increase storage usage since JPEG files are roughly twice the size of HEIC at equivalent quality. An alternative approach is to keep shooting in HEIC for storage efficiency and convert only the specific photos you need to share using this tool.
