Conversion Results:
# Output File Source File Action

Steps:

1. Click "Choose Files" button to select multiple files on your computer. You can also click the dropdown button to choose online file from URL, Google Drive or Dropbox. Image file size can be up to 200M.

2. Set target image format, image quality and image size. You can use the original image size or select "Change width and height" option and enter customized image size. The format is [width]x[height], for example: 1920x1080. Image quality option only works on a few image formats such as JPG, WEBP or AVIF etc. 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 or SVG etc.

HEIC vs BMP:
Name HEIC BMP
Full name High Efficiency Image File Format Microsoft Windows Bitmap
File extension .heic .bmp, .dib
MIME image/heic image/bmp, image/x-bmp
Developed by Moving Picture Experts Group (MPEG) Microsoft
Type of format Image Container Format Raster graphics
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 BMP file format, also known as bitmap image file or device independent bitmap (DIB) file format or simply a bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device, especially on Microsoft Windows and OS/2 operating systems.
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 bitmap image file consists of fixed-size structures as well as variable-size structures appearing in a predetermined sequence. Many different versions of some of these structures can appear in the file, due to the long evolution of this file format.
