NexusLabs Image Tools u{2014} 11 Tools av Akash Kumar Singh

Stop uploading your images to random websites just to resize or convert them. NexusLabs Image Tools gives you 11 powerful, privacy-first image utilities in a single beautiful popup — right in your browser toolbar.

Whether you need to switch between popular image formats, adjust dimensions, reduce file size, trim edges, tweak brightness and contrast, remove color, or generate placeholder graphics — Image Tools handles it instantly without leaving your current tab.

✅ What You Can Do

Convert between the most common image formats with a single click. Drop in a file and get the output in a different format instantly — supporting lossless and lossy conversions across five different format pairs. Quality is preserved automatically and every result can be downloaded immediately.

Resize any image to exact dimensions you specify. Enter width, height, or both — the tool shows the original size and lets you lock or unlock the aspect ratio. The resized version is previewed live before you download.

Compress images to reduce file size while controlling quality. A simple slider lets you choose how aggressively to compress, with real-time size estimates so you can find the perfect balance between quality and file weight.

Crop images by specifying exact pixel coordinates — set the starting position and the width and height of the region you want to keep. The cropped result previews instantly and can be saved with one click.

Adjust brightness and contrast with dedicated sliders that range from darkening to brightening and from flattening to sharpening. A reset button restores the original settings. Changes preview in real time before you commit.

Convert any image to grayscale using one of three rendering modes — luminance-weighted, simple average, or full desaturation. Each mode produces a different tonal result, and you can compare and download the version you prefer.

Generate placeholder images in any dimension you need, with customizable background and text colors. The generated image includes the dimensions as overlay text and downloads as a ready-to-use file — perfect for mockups and wireframes.
