This Utility API lets you apply filters such as image rotation, brightness adjustments, flipping, or Gaussian blur to enhance the aesthetics of the images of png, jpeg, jpg, bmp, tiff, gif or webp formats.
Image filters can improve the overall quality of an image by reducing noise, sharpening edges, and increasing contrast. This can be used to create artistic effects and alter the mood of an image.
Content creators can apply filters to ensure a professional and polished look. Businesses benefit by ensuring consistency in visual branding and adapting images for various platforms. Graphic designers and photographers find this utility indispensable for quick and precise image adjustments, optimizing their workflow.

All API requests to ApyHub services need to be authenticated. Currently we support tokens or basic authentication mechanisms. You can generate and view your existing credentials from your workspace settings (on the left side of the navbar) and go to “API Keys".
Points to note:
  • Credential secrets are generated on the fly and are not stored in plain text, so on generating a credential please save the secrets somewhere safe.
  • Use the apy-token as the header parameter to pass the token.
  • Use the Authorization header to send the basic authentication credentials.
