Image Quality


  • “Image quality” in this guide refers to both image size and JPEG/HEIF quality ().

Image Size Selection

You can specify Large, Medium, Small 1, or Small 2 for JPEG/HEIF images and RAW or Compact RAW for RAW images.


  • HEIF can be specified when [Shooting: HDR shooting HDR PQ] is set to [Enable]. You can convert these images to JPEG images after shooting ().
  1. Select [Shooting: Img type/size].

    • The screen displayed varies depending on [Stills Rec options] settings in [Set-up: Record func+card/folder sel.].
  2. Set the image size.

    Standard/Auto switch card/Record to multiple

    • For RAW images, turn the Main dial dial to select the size, and for JPEG/HEIF images, turn the Quick control dial 1 dial.
    • Press SET to set it.

    Record separately

    • When [Stills Rec options] in [Set-up: Record func+card/folder sel.] is set to [Rec. separately], turn the Quick control dial 1 dial to select [Card 1] or [Card 2], then press SET. Note that recording separately to RAW and Compact RAW is not available for RAW images.
    • Select an image size on the screen displayed, then press SET.


  • Large is set if you set both RAW and JPEG/HEIF to [Dash].
  • Two versions of each shot are recorded at your specified image quality when you have selected both RAW and JPEG/HEIF. Both images have the same file number but each has a different file extension, with .JPG for JPEG, .HIF for HEIF and .CR3 for RAW.
  • Meanings of image size icons are as follows: : RAW, : Compact RAW, JPEG: JPEG, HEIF: HEIF, : Large, : Medium, : Small 1, : Small 2.

RAW Images

RAW images are raw data from the image sensor that are recorded to the card digitally as RAW or Compact RAW, based on your selection. Compact RAW produces RAW images with smaller file sizes than RAW.

RAW images can be processed using [Playback: RAW image processing] () to save them as JPEG or HEIF images. As the RAW image itself does not change, you can process the RAW image to create any number of JPEG or HEIF images with various processing conditions.

You can use Digital Photo Professional (EOS software) to process RAW images. You can make various adjustments to images depending upon how they will be used and can generate JPEG, HEIF, or other types of images reflecting the effects of those adjustments.


  • To display RAW images on a computer, using Digital Photo Professional (EOS software, hereafter DPP) is recommended.
  • Older versions of DPP Ver. 4.x do not support display, processing, editing, or other operations with RAW images captured by this camera. If a previous version of DPP Ver. 4.x is installed on your computer, obtain and install the latest version of DPP from the Canon website to update it (), which will overwrite the previous version. Similarly, DPP Ver. 3.x or earlier does not support display, processing, editing, or other operations with RAW images captured by this camera.
  • Commercially available software may not be able to display RAW images captured by this camera. For compatibility information, contact the software manufacturer.

Guide to Image Quality Settings

See Still photo file size / Number of possible shots / Maximum burst for continuous shooting for details on file size, number of shots available, maximum burst, and other estimated values.

Maximum Burst for Continuous Shooting

The approximate maximum burst is displayed at the upper left of the shooting screen and lower right of the viewfinder.


  • If the maximum burst is displayed as “99”, it indicates that you can shoot 99 or more shots continuously. Fewer shots are available for a value of 98 or lower, and when [BUSY] is displayed on the screen, internal memory is full and shooting will stop temporarily. If you stop continuous shooting, the maximum burst will increase. After all captured images have been written to a card, you can once again shoot at the maximum burst listed in Still photo file size / Number of possible shots / Maximum burst for continuous shooting.


  1. Select [Shooting: JPEG/HEIF quality].

  2. Select the desired image size.

    • Select the image size, then press SET.
  3. Set the desired quality (compression).

    • Select the number, then press SET.
    • Higher numbers offer higher quality (lower compression).
    • Quality of 6–10 is indicated by Fine, and 1–5, by Normal.


  • The higher the quality, the fewer shots will be available. In contrast, the lower the quality, the more shots will be available.
