Seal Generator Online-summary

Online seal generator, supporting the online generation of company seals, institutional seals, and invoice seals. The generated electronic seal supports downloading to the local location.

Seal Generator Online-instructions
  1. This tool has a certain frequency limit, please use this tool reasonably. Anonymous user : 6/Hour*IP , Normal user : 6/Hour, VIP : 720/Hour, Senior VIP : 720/Hour.
  2. Examples of parameters for various parts of seal generate :
  3. Basic, Main Text, Border are required parameters for seal generation, while the rest are optional parameters.
  4. Basic : Specify the basic and public parameters for seal generation.
    1. Seal Style : Specify the style of stamp generation. This tool comes with 15 basic styles built-in. This includes circular seal styles, elliptical seal styles, square seal styles and rectangle seal styles. You can also choose to customize and use all custom parameters to generate personalized official seals.
    2. Seal Size : The pixel size of the generated stamp. The range of values is [501000].
    3. Seal Color : The color of the generated seal. The tool is built-in in red and vermilion. You can also choose other custom colors.
    4. Download : Select the format for downloading seal images. Picture with a transparent background in PNG format. A picture with a white background in JPEG format.
  5. Decorate : Use specific algorithms to age the generated seals. This section of parameters is optional and users can only use aging related parameters after logging in.
    1. Decorate : Select the algorithm for seal aging. Currently, there are two methods supported: none and adding noise.
    2. Direction:When adding noise, the gradient direction of the noise. When specifying globally, the starting intensity is used uniformly, without a gradient. In other directions, use the starting and ending intensities to generate gradient noise.
    3. Start, End : Add the intensity of noise in the range of [1,99].
  6. Main Text : Specify the main text parameters for seal generation. This section of parameters is required.
    1. Text : The text of the main text. Text input \n supports line wrapping display.
    2. Style : Choose whether the displayed text should be bold.
    3. Font Family : The font used to display the text. This tool uses fonts such as 宋体、楷体、仿宋、黑体、隶书、小篆 to generate seals. If you encounter text that is not supported by the font, it may display white space or garbled code.
    4. Font Size : The size of the seal text. The range is [1,1000].
    5. Text Space : The distance between words, ranging from [-1000,1000].
    6. Margin : The distance between the text and the edge, ranging from [-1000,1000].
    7. Fix : Adjust the left and right symmetry of text with circular and elliptical distributions to a range of [-1000,1000].
    8. Scale : Whether to stretch the height of the text, with a range of [0.5,2.0].
  7. Vice Text, Center Content, Title Text, Add Text : The text displayed in different regions allows you to flexibly use parameters such as text, font, text size, spacing, etc. in different regions, and flexibly combine them into various forms of seals. All parameters in this group are optional.
  8. The central content supports uploading image logos, which can upload up to 1MB files. The image format supports jpg, jpeg, bmp, and png formats. Suggest uploading images with transparent backgrounds. Support setting the size and rotation angle of image logos. When the displayed size does not match the original size of the image, the image will be scaled.
  9. Border : The outer edge line of the generated seal, required parameter.
    1. Line Size : The width of the edge line, which is 0, indicates that the corresponding edge line is not used.
    2. X-Radius : The radius of the X-axis of the edge line should be less than half the size of the seal. If the X-axis radius is equal to the Y-axis radius, the edge line is circular. If the X-axis radius is greater than the Y-axis radius, the edge line is an ellipse.
    3. Y-Radius : The radius of the Y-axis of the edge line should be less than half the size of the seal.
  10. Inner Border, Inner Circle : Other edges generated by the seal, optional parameters. You can use edges and their radius sizes to flexibly generate various forms of seals.
  11. Inner Rect : Generate rectangular edges inside the official seal. Optional parameters.
    1. Line Width : The width of the rectangular edge line inside the official seal, if 0, no rectangular edge line will be added.
    2. X : The X coordinate of the rectangle inside the official seal relative to the upper left corner of the official seal.
    3. Y : The Y coordinate of the rectangle inside the official seal relative to the upper left corner of the official seal.
    4. Width : The width of the rectangle inside the official seal.
    5. Height : The height of the rectangle inside the official seal.
