About CR2/CR3 to Image Converter

The CR2/CR3 to Image Converter allows you to upload Canon RAW files (.CR2 and .CR3) and convert them into standard image formats directly in your browser. This tool supports multiple output formats and batch conversion, making it easy to process RAW photos into commonly used image types.

What Is This Tool?

This tool is designed to convert Canon RAW image files (CR2 and CR3) into widely supported image formats such as JPG, PNG, WEBP, TIFF, BMP, AVIF, HEIC, and SVG.

It allows you to:

  • Upload multiple RAW files

  • Choose your preferred output format

  • Convert all files in one click

  • Download individually or as a ZIP file

What Are CR2 and CR3 Files?

CR2 and CR3 are RAW image formats used by Canon cameras.

These files:

  • Store unprocessed image data directly from the camera sensor

  • Contain high-quality image information

  • Are typically large in size

  • Require special software or conversion to be viewed as standard images

Because many applications and websites do not support RAW formats directly, converting them to standard formats like JPG or PNG makes them easier to share and use.

Supported Input Files

This converter accepts:

  • .CR2 files

  • .CR3 files

Each file can be up to 150 MB in size.

Files with other extensions are automatically rejected during upload validation.

Supported Output Formats

You can convert CR2 and CR3 files into the following formats:

  • JPG

  • PNG

  • WEBP

  • TIFF

  • BMP

  • AVIF

  • HEIC

  • SVG

The desired output format is selected using radio buttons before conversion.

How It Works

Step 1: Upload Files

Upload CR2 or CR3 files using drag-and-drop or file selection.

Step 2: Choose Output Format

Select your desired output format from the format selector.

Step 3: Convert

Click "Convert Images" to start batch conversion.

The tool:

  • Processes RAW data using optimized settings

  • Converts the image into the selected format

  • Saves the converted image with a unique filename

Step 4: Download

Download converted images individually or as a ZIP file.

Output Format Behavior

Each format is saved with appropriate handling:

  • JPG: Saved in RGB mode with quality optimization

  • PNG: Saved with optimization enabled

  • WEBP: Saved with compression and quality settings

  • TIFF: Saved with compression

  • BMP: Converted to RGB if needed

  • AVIF: Attempts conversion; if unsupported, falls back to PNG

  • HEIC: Attempts conversion; if unsupported, falls back to PNG

  • SVG: Embeds the converted PNG image inside an SVG wrapper

If a format fails (such as AVIF or HEIC), a PNG fallback file may be created and returned with a warning.

Conversion Results

After conversion:

  • The results section becomes visible

  • Each converted file is listed

  • You can download files individually

  • Warnings are shown if any file had fallback behavior

  • If conversion fails, error information is returned per file

If no files are successfully converted, the tool displays a message indicating the issue.

Frequently Asked Questions

Find answers to common questions about this tool

Each upload session is assigned a unique session_id. Uploaded files are stored in a session-specific temporary directory and registered server-side. During conversion, the tool matches requested files against that session to ensure only valid uploaded files are processed.

The tool strictly validates file extensions. Only files ending in .cr2 or .cr3 are accepted. Other image formats such as JPG, PNG, or TIFF are intentionally rejected during upload.

If a file does not match the current session's uploaded files, the tool returns:

File not found or not uploaded in this session

This prevents unauthorized file access across sessions.

Each converted file is assigned a unique filename using a UUID prefix. This prevents filename collisions when multiple files share the same original name.

If AVIF or HEIC conversion fails due to format support issues, the tool attempts to save the image as PNG instead. In such cases:

  • The PNG file is returned

  • A warning message is included in the response

Yes. Uploaded files are securely processed and automatically deleted after conversion.
