Image to HEIC Converter Online

HEIC (High Efficiency Image Container) is Apple's modern image format that uses the HEVC compression algorithm to store images at roughly half the file size of JPEG while maintaining equivalent or better visual quality. If you have images stored as JPG or PNG that you want to save to an iPhone or iPad, archive on Apple hardware, or simply reduce in storage size without noticeable quality loss, converting to HEIC achieves all of these goals — producing significantly smaller files that integrate natively with Apple's ecosystem.

At the default quality of 80, HEIC typically produces files that are 40–50% smaller than an equivalent JPEG at the same visual quality. A 4MB JPEG photograph commonly becomes a 1.5–2MB HEIC file. At quality 60, reductions of 60–70% are common. The exact result depends on the content of the image — photographs with complex colour gradients benefit more from HEIC compression than simple flat-colour graphics.

The tool accepts all standard web image formats: JPG, JPEG, PNG, WebP, BMP, GIF, and TIFF. Any image you upload is converted to HEIC at your chosen quality level regardless of the source format.

For general photography storage and sharing: use 80 (the default — matches iPhone's own HEIC quality). For archival where quality is paramount: use 90–100. For maximum storage savings where minor quality reduction is acceptable: use 60–70. For web thumbnails or previews where file size matters most: use 40–60. Avoid values below 30 unless you specifically need the smallest possible file — compression artefacts become noticeable below this threshold for most photographs.

No. Your image is uploaded for conversion and the HEIC result is returned to your browser. No copy of your original or converted image is retained on our servers after the conversion is complete.
