Private preparation tools

Prepare a signature

Prepare a scanned or photographed signature. Trim excess space while keeping every stroke visible, then enter the limits from your application instructions.

Use a clear, evenly lit scan or photo. Keep all signature strokes inside the crop. This tool does not remove backgrounds, clean ink or verify signature authenticity.

Select a file

Loading image controls. File selection will be available shortly.

JPG, JPEG or PNG. Up to 20 MB, 16 million pixels and 8,192 pixels per side. Animated PNG is not supported.

Your original and prepared image will appear here after you choose a file.

Crop (optional)

Choose how to prepare it

Not sure? Use Recommended signature. Keep the current dimensions and save as PNG, preserving transparency. You can trim empty space without losing any strokes.

An application asking for a particular size needs Custom settings. Recommended does not certify any application's requirements.

Output plan: PNG · Keep current dimensions

Advanced settings

Only change these if you need a specific format, dimensions or file size. Copy the limits from your application instructions. Blank limits add no requirement.

Output settings

Blank dimensions keep the current size. Keeping proportions fits within both limits. Exact dimensions can fail if the proportions differ or enlargement is disabled. Turning proportions off can stretch the image. Enlargement cannot restore detail.

Optional. 1 KB = 1,000 bytes. Use the units specified by your application. A size match does not override other failed checks.

How to use this tool

  1. Choose a JPG, JPEG or PNG. Review the original image and its measured size.
  2. Use Recommended, or choose Custom for your application’s size requirements. You can optionally trim the image first.
  3. Prepare the image. Check the preview and validation result, then download explicitly.

Local processing, original preserved

Your image is processed in this browser. Its contents and name are not uploaded or saved by this tool. Reset clears the selection and previews; any pending native work releases its resources when it finishes. Downloads you save remain on your device.

Before you submit

A pass covers only the settings you entered, not portal acceptance, pose, background or legibility. JPEG uses a white background for transparency; PNG keeps it. PNG is encoded once, so its file size may not meet your target. Colour may vary with browser encoding. Current automated browser coverage is Chromium; Firefox, Safari and mobile devices still need release testing.
