What proportions does the rectangle use?

The canvas height is set to roughly 55% of the width, matching the wide, shallow proportions of a typical self-inking office stamp rather than a tall or square box.

Can I add a second line of text?

Yes, the optional subtext field adds a smaller centered line beneath the main text, a common layout for 'RECEIVED' or 'APPROVED BY' style stamps.

How is this different from the Custom Stamp Design Creator?

This tool is the same composer with the shape locked to rectangular, so there's no shape toggle to set if you already know you want a rectangular stamp.

Can I change the ink color?

Yes, any RGBA ink color is supported; it defaults to a classic stamp red.

Rectangular Stamp Creator - Make a Boxed Rubber Stamp PNG

Overview

Introduction

This tool builds a rectangular rubber-stamp graphic: a double-ring box border with your text centered inside it, in the wide, shallow proportions typical of a self-inking office stamp.

It's a shape-locked convenience wrapper around this category's shared stamp composer, for when you already know you want a rectangular stamp.

What Is Rectangular Stamp Creator?

A rectangular-only wrapper around createCustomStampDesign, the shared stamp composer this whole batch of tools builds on.

It draws a concentric double-ring rectangular border inset from the canvas edges and centers up to two lines of text inside it.

How Rectangular Stamp Creator Works

The canvas height is derived from the requested width at a fixed ratio matching typical self-inking stamp proportions, rather than a fixed square.

The double-ring border is drawn as two inset rectangular frames, and your text (plus optional subtext) is measured and centered inside them using the shared bitmap font.

When To Use Rectangular Stamp Creator

Use it whenever you want the classic wide 'RECEIVED'/'APPROVED'/'PAID' desk-stamp look rather than a circular seal.

It's a one-less-click alternative to the Custom Stamp Design Creator when the shape is already decided.

Often used alongside Custom Stamp Design Creator, Round Stamp Creator and Date and Time Stamp Creator.

Features

Advantages

Matches realistic self-inking stamp proportions automatically.
Supports an optional second text line for a status/date pairing.
Runs entirely client-side, producing a downloadable transparent PNG.

Limitations

The shape can't be changed to round from this tool — use the Round Stamp Creator or Custom Stamp Design Creator for that.
The bitmap font only supports uppercase A-Z, digits, and spaces.

Examples

An 'APPROVED' desk stamp

Input

text="APPROVED"

Output

A wide rectangular PNG with a double ring around APPROVED

The default proportions match a typical self-inking desk stamp.

A 'RECEIVED' stamp with a date line

Input

text="RECEIVED", subtext="26 07 2026"

Output

A wide rectangular PNG with RECEIVED on top and the date centered below

The subtext line renders smaller and centered beneath the main text.

Best Practices & Notes

Best Practices

Keep the main line to one or two short words for the most balanced rectangular composition.
Use the subtext line for a date or reference number rather than a second full word.

Developer Notes

The lib function forwards directly to createCustomStampDesign with shape fixed to "rectangular", adding no new rendering logic of its own.

Rectangular Stamp Creator Use Cases

Creating an APPROVED/RECEIVED/PAID stamp graphic
Mocking up a self-inking desk stamp's layout
Prototyping a boxed status stamp for a document template

Common Mistakes

Trying to pass a round shape to this tool — it's locked to rectangular by design; use a different tool for round output.
Expecting a tall or square box; the proportions are deliberately wide and shallow.

Tips

Pair with the Green Stamp or Red Stamp creators for themed ink colors on a rectangular shape.
Use the subtext line for a short date or ID number to complete the classic desk-stamp look.
