Tool usage guide
The Image Binary Converter allows you to transform any color or grayscale image into a high-contrast monochrome format. By applying a specific threshold value, you can isolate shapes, simplify complex visuals, or prepare images for OCR and stencil printing.
Background
A collection of old, faded documents needs to be digitized for a database.
Problem
The original scans have gray backgrounds and low-contrast text, making them difficult to read.
How to use
Upload the scan and set the threshold to 180 to push the gray background to white and the text to solid black.
threshold: 180, invert: falseOutcome
A crisp, high-contrast black-and-white document that is perfectly legible for archival storage.
Background
A designer needs to create a simple stencil pattern from a portrait photo.
Problem
The photo has too much detail and color depth for a simple two-layer stencil.
How to use
Upload the portrait and adjust the threshold until the facial features are clearly defined in black and white.
threshold: 120, invert: trueThe threshold determines the brightness cutoff. Pixels with a value equal to or greater than the threshold become white, while those below it become black.
Yes, checking the 'Invert Result' box will swap the black and white pixels in your final image.
You can upload JPEG, PNG, WebP, GIF, BMP, and TIFF files.
Yes, the maximum allowed file size for processing is 10 MB.
No, this tool is designed to process one image file at a time.
Outcome
A clean, inverted monochrome image ready to be printed and cut as a stencil.
