Stampy

Stampy is a browser-based logo-to-stamp layout tool, with its official address at https://logotostamp.com/。其用途是把用户已有的 Turn a logo into a stamp-style composition: add a border around the logo (circle, ellipse, rectangle, or square), and optionally add surrounding text to form an overall design similar to a stamp, then export it as a digital graphic file.

Main capabilities:

1. Local image upload and editing. Users can upload a logo file in the browser, add it as a layer, and move, scale, or rotate it until the visual center is balanced.
2. Border and text editing. Circle or ellipse borders can be chosen for compact marks, while rectangle or square borders can be chosen for wider logos; text can be used to indicate the team, studio, project, or internal use.
3. Export transparent PNG or SVG. After editing is complete, users can download a 1600×1600 transparent PNG, or download an SVG (borders and text are vector, and the uploaded image layer is saved in the file as embedded content).
4. The companion Stamp Image Cleaner. For marks obtained on white paper or from photo scans, this tool can first be used to separate useful colors and export a transparent PNG, then return to the logo editor to use it.

How to use (organized according to official instructions):

1. Prepare and upload a logo. It is recommended to use the cleanest source file you have; transparent PNG or SVG is usually easiest, because it will not bring a white rectangle into the design; JPEG and WebP are also accepted, but their background will remain in the image. If the mark was photographed or scanned onto paper, first use Stamp Image Cleaner to separate colors and download a transparent PNG. Uploaded files must be less than 5 MB.
2. Combine the mark, border, and text. Add the image as a layer, and move, scale, or rotate it until the visual center is balanced; leave a gap between the logo and the border to avoid looking crowded when scaled down. Choose a border that matches the shape of the logo; edit the surrounding text to explain the team, studio, project, or internal use, and do not imply an authoritative identity you do not have.
3. Check readability at small sizes and download. Zoom out to view the overall effect, and note that narrow gaps may close, fine gradients may become blurry, and long text may conflict with the image. If the recipient's workflow requires scalable graphics, download SVG; if the software requires a bitmap, use the 1600×1600 transparent PNG. After downloading, open it in the actual target application to confirm transparency, size, and visual alignment.

Export format notes: SVG keeps borders and text as vectors, and embeds the uploaded image layer, making it suitable when design or layout tools support SVG and repeated scaling is expected. However, it must be tested in the actual software, because the degree of support for embedded image data varies;An embedded bitmap logo does not become a newly traced vector logo just because the container is SVG. The PNG is a 1600×1600 transparent bitmap, suitable for documents, presentations, image editors, and other tools that accept PNG. The area around the stamp graphic remains transparent, but the white background inside the uploaded logo will still be visible. It should be scaled proportionally in the target application to avoid circles becoming ellipses or text deforming; also check at the final size, since a large source file does not guarantee that details remain clear after downsizing.

Applicable scenarios and examples: A transparent monochrome logo can be placed in the center of a circular stamp, with short text added around the edge, and is the most predictable input. A logo with a white background will show a white rectangle; if that effect is not wanted, you can first use the local Stamp Image Cleaner to select the relevant ink color, adjust the sensitivity, export a transparent PNG, and then return to the editor (after cleaning, check the edges, as very light details may disappear). A wider horizontal logo is better used with a rectangular or elliptical canvas, with less surrounding text, blank space on both sides, and without stretching the image. Artwork with many details or multiple colors should be previewed at the actual display size; fine strokes, gradients, and similar colors may merge, so consider using a simpler licensed version.

Limitations and boundaries: Stampy only exports digital graphics, does not test all third-party applications, does not automatically convert white-background logos to transparent, does not certify print production, and does not make physical rubber stamps. A clean preview does not constitute trademark permission, regulatory acceptance, or proof of suitability for all printing and document workflows. Whether it can be used commercially or as a company's official seal is not clearly licensed in the official text; it is recommended to confirm authorization and compliance yourself.
