Examples

1. Print-Ready Brochure Conversion

Graphic Designer
Background
A designer created a brochure in sRGB, but the print shop requires CMYK files to prevent color inaccuracies.
Problem
The colors appear vibrant on screen but look washed out when printed using standard RGB files.
How to Use
Upload the brochure image, select 'sRGB' as the input profile, and set quality to 95.
Example Config
quality: 95, inputProfile: 'srgb'
Outcome
A high-quality CMYK JPEG file that maintains color integrity for professional printing.

2. Preserving Metadata for Portfolio Prints

Photographer
Background
A photographer needs to send high-resolution photos to a gallery for print, but wants to keep the original camera settings and copyright info.
Problem
Standard conversion tools often strip away essential metadata during the color space transformation.
How to Use
Upload the photo, check 'Keep Metadata', and process the file.
Example Config
keepMetadata: true, quality: 100
Outcome
A CMYK-converted image that retains all original EXIF and copyright metadata for professional archival.
