How to use Create Black and White JPG
- 1. Upload the JPG photo. Drop or browse for the .jpg or .jpeg file you want to convert. It loads into the preview so you can decide where the split between black and white should fall.
- 2. Set the Threshold (0-255). Move the Threshold (0-255) slider: pixels brighter than the threshold turn pure white, pixels darker turn pure black. Raise it to shift more of the image toward black, lower it for more white.
- 3. Download the high-contrast photo. The tool snaps every pixel to pure black or pure white based on the threshold you set, leaving no midtones. Download the stark, high-contrast JPG result.
When to use Create Black and White JPG
Create Black and White JPG forces every pixel to either pure black or pure white with no gray in between, unlike a grayscale conversion that preserves midtones. The threshold controls exactly where that hard cutoff sits.
- Making a stencil design from a photo. A photo needs to become a stencil pattern for a craft project; snapping it to pure black and white at a threshold around 128 gives clean, cuttable shapes.
- Creating a high-contrast logo mark from a photo. A photographed sketch needs to become a stark, bold logo mark; a threshold conversion turns the shading into a clean two-tone graphic.
- Improving readability of a low-quality scan. A faint, unevenly lit scanned document needs its text to stand out starkly; a threshold pass turns the faded gray text into solid black on white.
- Preparing artwork for a 1-bit display or laser cutter. A photo needs to be converted to strict black and white before feeding it into a device or process that only understands two tone values.

About the Create Black and White JPG tool
Create Black and White JPG runs as plain JavaScript in your browser tab, with no server behind it. Force every pixel of a JPG to pure black or pure white: no midtones. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's JPG Tools section, 145 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Threshold (0–255) setting, and the result refreshes the moment you change it. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
