Examples

1. Preparing RAW Landscape Photos for Web Portfolios

Landscape Photographer
Background
A photographer has a series of high-contrast CR3 RAW files shot on a Canon EOS R series camera that need to be uploaded to a web portfolio.
Problem
The CR3 files are too large and incompatible with web browsers, and some sky highlights are slightly overexposed.
How to Use
Upload the CR3 file, set the Highlight Recovery to 5, adjust Brightness to 1.1, set the PNG Compression Level to 9 for the smallest file size, and convert.
Example Config
Compression Level: 9, Brightness: 1.1, Highlight Recovery: 5
Outcome
A web-ready, lossless PNG image with recovered sky details and optimized file size.

2. Converting Studio Portraits for Client Previews

Studio Portrait Photographer
Background
A photographer needs to quickly send lossless previews of CR3 RAW files to a client who does not have specialized RAW viewing software.
Problem
The client cannot open CR3 files, and the original images are too large to send over email.
How to Use
Upload the CR3 file, set the Output Width to 1920 to downscale the preview, set Saturation to 1.1 for more vivid colors, and convert.
Example Config
Width: 1920, Saturation: 1.1, Compression Level: 6
Outcome
A high-quality, resized PNG preview that the client can open instantly on any device.

Can I resize the image during the conversion process?

Yes, you can specify custom output width and height values in pixels to resize the image.

How does the highlight recovery option work?

It helps restore details in overexposed or blown-out highlights, with higher values applying more aggressive recovery.

Will the tool preserve my camera's metadata?

Yes, the converter automatically extracts and preserves image dimensions and metadata from the original CR3 file.

What does the PNG compression level setting do?

It ranges from 0 to 9, where 0 is the fastest conversion with larger file sizes, and 9 produces the smallest file size but takes longer.
