- Result
- One proportional JPEG and its actual byte size
Smaller images are not enlarged. The quality setting is not a promised reduction percentage.
Re-encoding instead of renaming
Renaming .heic to .jpg does not create a JPEG. This tool decodes the primary image inside HEIF and re-encodes it as JPEG in the browser. The result is one primary image even when the source contains additional images or depth data; motion and image sequences are not retained.
The decoder is loaded separately only when conversion is requested. The photo is not uploaded to this site’s server. A replaceable open-source decoder file and license notice are supplied separately. Conversion runs in a worker and can be cancelled.
Check quality, color and metadata
JPEG is lossy. Lowering quality may reduce file size but also changes detail. HDR photos may look different in an ordinary JPEG, so compare the result with its source and keep the HEIC for printing or archival needs.
EXIF, GPS, capture dates and depth information are not copied. Transparent areas are composited over white. Limits are25 MB and24 million pixels; a large photo can still stop at the device-memory or decoder time limit.
Common questions
Is the original photo changed or removed?
No. The selected photo is read to create a separate JPEG result. The source file is not overwritten or automatically saved.
Are all images inside a multi-image HEIC converted?
Only its primary image is converted. Auxiliary images, depth maps, sequences and a Live Photo’s video are not included in the JPEG.
