Black and White Image
Two Tones, Maximum Drama
Not grayscale - pure black and white. Threshold conversion reduces every pixel to one of two values, creating bold graphic statements.

Features
Precise threshold control
256 cutoff levels let you dial exactly where gray becomes black versus white.
True binary output
Only two values exist in results - genuine black and white, not dark and light gray.
Stencil-ready results
Two-tone outputs feed laser cutting, screen printing, and vinyl workflows.
Logo extraction aid
Sketches and signatures clean into usable marks.
PNG format
Lossless storage preserves the crisp edges thresholding creates.
Live slider feedback
Adjustments show immediately in processing.
Two-tone applications
The power of reduction to two values
Graphic punch
Binary images command attention through sheer contrast.
Production readiness
Single-color processes require exactly this input.
Interpretive clarity
Thresholding forces decisive shape reading.
Tiny file sizes
Two-value images compress extraordinarily well.
Thresholding is the most opinionated filter
Most image operations negotiate - softening here, enhancing there. Thresholding dictates: every pixel must choose allegiance. Above the cutoff, pure white; below, pure black. No survivors in between. This absolutism creates both the technique's power and its demands.
The cutoff position IS the artwork. Slide it low and shadows swallow the frame; slide high and highlights erase detail. The sweet spot depends entirely on subject and intent - a portrait might want eyes preserved while a stencil wants maximum mass. There's no correct answer, only deliberate ones.
Practical applications abound where continuous tones simply cannot go. Screen printing lays down one ink color; vinyl cutters follow contours; laser engravers modulate power binary-style. All depend on two-tone inputs, making threshold conversion less an effect and more a translation into manufacturing language.
“Customer art arrives in every state; thresholding with adjustable cutoff preps screens perfectly.”
Diego Fuentes - Screen printer
“My designs start as photos reduced to essential blacks and whites - the slider finds the soul.”
Emma Larsson - Papercut artist
“Converting reference photos to pure B&W clarifies what will actually read as ink.”

Frequently asked questions
What's the difference between this and grayscale?
Grayscale keeps continuous tones; thresholding collapses everything to pure black or pure white with nothing between.
How do I choose the right threshold?
Slide and observe - the best cutoff preserves essential shapes while eliminating midtone clutter. Subject-dependent entirely.
Why does output come as PNG?
PNG stores the hard edges losslessly; JPEG would blur the crisp binary boundaries thresholding creates.
Can I recover the original after thresholding?
No - the operation discards tonal information permanently. Keep originals.
What images threshold best?
High-contrast subjects with clear figure-ground relationships: portraits against plain backgrounds, bold logos, dramatic lighting.
Is this suitable for print production?
Exactly - single-ink processes require binary input, which is precisely what thresholding delivers.
