About HEIC Converter
HEIC (High Efficiency Image Container) is the standard image format used by iPhone and iPad devices to store high quality pictures with minimal storage footprint. However, many desktop operating systems, websites, and legacy applications cannot open or process HEIC files natively. Solasu HEIC Converter solves this incompatibility by decoding HEIC images locally in your browser using modern WebAssembly and Web Workers, transforming them into standard JPG or PNG images without ever transmitting your photos to external servers.
Choose Between JPG and PNG Output
JPG is recommended for photographic scenes and everyday pictures where compact file size is preferred. You can easily calibrate compression with the quality slider (1-100, default: 90).
PNG offers lossless preservation and supports transparent channels. If your HEIC contains alpha channels or transparency, PNG preserves it cleanly. When converting transparent images to JPG, an optional background color can be configured in Advanced Settings.
Batch Conversion and One-Click ZIP Download
Process multiple photos in a single batch. By utilizing background Web Workers and sequential file pipeline execution, your browser stays smooth and responsive without freezing even during large workloads.
When converting multiple images, download individual files separately or bundle all converted pictures into a clean ZIP archive with one click.
Resolution Controls & Privacy Protection
Use Advanced Settings to resize pictures by maximum edge, explicit width, or height. The default 'No Upscale' option guarantees smaller pictures will not be artificially stretched or degraded.
Metadata such as EXIF and GPS information from the input image is not carried over to the output image. Converted images have their visual orientation normalized directly in the pixel buffer for correct upright display.
Frequently Asked Questions (FAQ)
Can I convert HEIC to JPG?
Yes. You can quickly convert any HEIC or HEIF image to high-standard JPG format, adjusting quality between 1 and 100.
Can I convert HEIC to PNG?
Yes. Selecting PNG produces clean, lossless images that maintain transparency whenever present in the source HEIC image.
Can I convert iPhone HEIC photos to JPG?
Yes. iPhone and iPad camera photos can be directly selected or dropped into Solasu. Image orientation is normalized directly in the pixel buffer so vertical shots remain upright.
Are my HEIC files uploaded to a server?
No. All decoding and image processing executes strictly inside your browser environment (WebAssembly and Web Worker). Your files never leave your device.
Can I convert multiple HEIC files at once?
Yes. Drag and drop multiple files to batch convert them. The finished files can be downloaded individually or as a single ZIP archive.
Can I adjust JPG quality?
Yes. In Advanced Settings, use the quality slider (1-100, default: 90) to balance detail retention against file size.
Can I resize my images during conversion?
Yes. You can specify a target longest edge, width, or height. The aspect ratio is preserved and smaller images will not be upscaled by default.
Is EXIF and GPS metadata carried over to the output image?
No. Metadata such as EXIF and GPS information from the input image is not carried over to the output image. If the input image contains GPS location details, they are omitted during canvas re-encoding in your browser. Visual orientation is normalized directly in the pixel buffer so the output image displays upright.
What happens when converting transparent HEIC to JPG?
Because JPG does not support alpha channels, transparent areas are filled with your chosen background color (default: white). Choose PNG if you want to keep transparency.
Where are the converted images saved?
Files download directly to your computer or phone's standard Downloads directory. Nothing is saved in the cloud.
Can I convert large images?
Yes, high-resolution smartphone photos are fully supported. To protect browser stability, pictures exceeding 8,192px on the longest edge or 64 megapixels are halted for safety.
