The free workflow starts in the browser and does not require an account before file export.

Ad-safe

Downloads are not gated behind ad interactions or ad impressions. Ads remain disabled until policy review and search visibility are ready.

Use the 50KB target

Open the image-to-KB compressor with 50KB prefilled. A clear black signature on a plain background usually compresses well at this target.

Resize first if pixels are required

Some portals require a specific signature box such as 140 x 60 or 200 x 100 pixels. Resize the signature first, then compress the resized file.

Keep it readable

Do not over-compress until the signature becomes faint or broken. This is a visual file helper, not identity verification or regulated e-signature software.
