What changes when you convert HEIC to JPG?
Keep the main photo useful while understanding color, metadata, extra images, and JPEG quality.

Convert a photo, then check the destination
Use HEIC to JPG when the destination accepts JPEG but does not accept your HEIC file. Convert the primary still photo, check its orientation and appearance in the preview, and open the downloaded JPG in the app that will receive it. Keep the original HEIC if you may need its extra information later.
One HEIC file can contain more than one image
ToolMellow converts the primary still photo declared in the container. Additional photos, thumbnails, depth information, HDR gain maps, and Live Photo video are not exported as separate files. When the local fallback decoder finds multiple top-level photos, the result states how many it found and which selection policy was used.
JPG quality and dimensions solve different problems
The quality slider controls lossy JPEG encoding. It does not change the pixel dimensions. To make the image smaller in width or height, choose Resize image on the result, set the dimensions, and use Fit inside to keep the whole picture. Inspect fine detail after lowering quality or dimensions.
Color needs its own check
The output is an 8-bit SDR JPG for ordinary viewing. Supported RGB ICC profiles and sRGB/Display P3 encodings are converted for sRGB output using the browser’s color handling or a local fallback converter. PQ or HLG HDR photos require an SDR export first in this version. The tool reports when unspecified color information is treated as sRGB; review color-critical work in the intended viewer.
Choose what happens to photo metadata
Remove metadata is the default: the JPG has no original GPS location, camera settings or dates. Keep EXIF copies the primary photo’s EXIF, including location when present, while updating orientation, dimensions and color tags to describe the output JPG. Standard EXIF thumbnails are removed to avoid stale previews. Separate XMP and other metadata items are not copied; proprietary maker-note interpretation varies across software. An absent EXIF block is reported explicitly. Damaged or unsupported EXIF, or metadata exceeding JPG’s 64 KB segment limit, stops preservation instead of silently dropping fields; choose Remove metadata to continue without it. Keep the original HEIC as the complete archive of the capture.
Continue without selecting the file again
The result can move directly into Image resizer or JPG to PDF in the same tab. These transfers happen in page memory. A subsequent image resize or PDF assembly uses rendered pixels and does not retain the JPG’s EXIF. Download the JPG first when its retained metadata matters; download a copy before closing or refreshing the temporary workspace.
