How to convert HEIC to DDS:
1. Click the "Choose Files" button to select multiple files on your computer or click the "URL" button to choose an online file from URL, Google Drive or Dropbox. Image file size can be up to 200M. You can use file analyzer to get source image's detailed information such as image size, resolution, quality and transparent color.
2. Set target image format, image quality and image size. You can use the original image size or select the "Change width and height" option and enter a custom image size. The format is [width]x[height], for example: 1920x1080. The image quality option only works on a few image formats such as JPG, WEBP or AVIF. The value ranges from 1 (lowest image quality and highest compression) to 100 (best quality but least effective compression). If this value is blank, the converter will use the estimated quality of your input image if it can be determined, otherwise 92. The target image format can be JPG, PNG, TIFF, GIF, HEIC, BMP, PS, PSD, WEBP, TGA, DDS, EXR, J2K, PNM, SVG, etc.
3. Click the "Convert Now!" button to start batch conversion. It will automatically retry conversion on another server if one fails, please be patient while converting. The output files will be listed in the "Conversion Results" section. Click icon to show file QR code or save file to cloud storage services such as Google Drive or Dropbox.
HEIC vs DDS:
| Name | HEIC | DDS |
| Full name | High Efficiency Image File Format | Microsoft Direct Draw Surface |
| File extension | .heic | .dds |
| MIME | image/heic | image/vnd.ms-dds |
| Developed by | Moving Picture Experts Group (MPEG) | Microsoft |
| Type of format | Image Container Format | Texture files |
| Introduction | As HEIC is a container format, it can contain still images and image sequences (where a file contains more than one single image) that are coded in different formats. Currently, these include HEVC and H.264/MPEG-4 AVC (and JPEG for thumbnail/secondary images), though other coding formats may be added in the future. The main filename extension is .heic (for HEVC codec). | The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the proprietary S3 Texture Compression (S3TC) algorithm, which can be decompressed in hardware by GPUs. |
| Technical details | In Apple's implementation, for single images they have chosen the latter .heic filename extension (.heics for image sequence files) as the only one they will produce for photos, which indicates clearly that it went through HEVC encoding. | The DirectDraw Surface format is useful for storing graphical textures and cubic environment maps as a data file, both compressed and uncompressed. The Microsoft Windows file extension for this data format is '.dds'. |
