No settings needed. Each image becomes a four-panel PNG with C, M, Y and K ink views side by side.
Nothing is uploadedHow it works
Add your images
Choose JPG, PNG, WebP, GIF, BMP, AVIF or HEIC images to preview as CMYK ink plates.
View the CMYK strip
Each photo becomes one wide PNG with cyan, magenta, yellow and black grayscale panels joined in order.
Download the strips
Save each four-panel PNG on its own or download all strips together as a ZIP.
What the C, M, Y and K panels show
The four panels show ink amounts for printing: cyan, magenta, yellow and black key. White means no ink and black means full ink for that plate, the opposite of screen light.
A blue sky is strong in cyan with little yellow, while skin needs magenta and yellow with some black in shadows. Large black areas in K show where the printer adds depth.
How to read the strip
Add one or more images and the tool builds a four-times-width PNG with the four plates joined. The result keeps full resolution, so text edges and fine patterns stay sharp for inspection.
Processing is fully local, leaving no trace on any outside machine. Your originals are read in memory and only the strip PNG is offered for saving.
When a CMYK view helps
Use CMYK before sending work to print to spot rich blacks, ink-heavy skies or skin that will shift on paper. Screens show RGB light, so this preview reveals what the press will actually lay down.
For screen colour learning use Show RGB channels instead, which matches light rather than ink. Download the CMYK strip PNG on its own, or convert a batch and collect everything in one ZIP.
Questions
Are my images uploaded?
No. Your images are opened and split inside your browser. They never leave your device.
What does K stand for?
K is black, called key. It adds depth and sharp text instead of mixing cyan, magenta and yellow alone.
Will my screen colours match print?
Not exactly. Bright screen greens and blues often print duller. The K panel shows where black ink compensates for that.
Is it free?
Yes. Free to use, with no sign-up, no watermark and no daily limits.
