Why Batch Convert Color Spaces?
Manually converting images one by one in Photoshop or similar tools is time-consuming. When you have 10, 20, or 50 files that all need to go from Adobe RGB to sRGB before a web upload, batch conversion saves significant time. imgxcolor processes all files client-side using the Canvas API, so your machine does the work — no waiting for server uploads or cloud processing.
Output as ZIP — Ready to Use
All converted images are bundled into a single ZIP file for one-click download. Files are renamed with a _converted suffix so originals are never overwritten. Choose PNG for lossless output or JPG for smaller file sizes.
100% Private — Nothing Leaves Your Browser
Every pixel is processed locally using JavaScript and the Canvas API. No file ever touches a server. This makes imgxcolor's batch converter safe for confidential client assets, medical images, or any proprietary design files.
ICC-Accurate Color Math
Conversions route through CIE XYZ as a neutral intermediate space, using the correct primary chromaticities and transfer functions for each profile — the same approach used by professional ICC-compliant color management engines like those in Photoshop and Lightroom.
Frequently Asked Questions
How many images can I convert at once?
Up to 50 images per batch. All processing happens in your browser so the limit is based on available RAM rather than a server cap. For most modern devices, 50 images at typical web resolution process in well under a minute.
Can I batch convert CMYK images to sRGB?
Yes — select the "CMYK → RGB" conversion type, choose your target RGB profile (sRGB for web), and convert. For more control over individual images, use the dedicated CMYK → RGB converter.
What is the CMYK → CMYK option for?
It re-profiles CMYK images from one press standard to another — for example converting FOGRA39 files to SWOP for US printing. This is useful when adapting European print files for North American presses or vice versa.
What happens to my original files?
Nothing — your original files are never modified. The converter reads each file into memory, applies the color transform, and generates a new file. Converted files are renamed with a _converted suffix and bundled into a ZIP download.
Is the batch converter free?
Yes — completely free, no account, no watermarks, no usage limits. All processing is client-side so there is no server cost involved.
