Imgix

Apply automatic image optimizations using imgix's auto parameter. Use this tool to automatically optimize images for web delivery. Common use cases: - Reduce file sizes with 'compress' for faster page loads - Auto-select modern formats (AVIF/WebP) with 'format' based on browser support - Enhance image quality with 'enhance' (adjusts brightness, contrast, saturation) - Remove red-eye from portrait photos with 'redeye' Multiple options can be combined (e.g., ['compress', 'format']) for cumulative optimizations. The 'true' option is a convenient shorthand that applies 'enhance' automatically. Note: This tool works with the imgix Rendering API and requires a valid imgix source domain. For testing, use 'assets.imgix.net' with paths like 'examples/kingfisher.jpg'.

Tool to overlay an image, text, or color onto a base image using imgix blending parameters. Use after specifying the base image URL and blend parameters to composite layers.

Tool to align the overlay relative to the base image when blending. Use after constructing a base Imgix URL to specify horizontal and vertical alignment (e.g., 'left,top').

Tool to blend a solid color over an image using CSS keyword or hex. Use when you need to apply color overlay transformations to an existing image URL.

Position an overlay image horizontally on a base image using imgix's blend-x parameter. Use this tool when you need to place an overlay (image or color) at a specific horizontal offset from the left edge of the base image. This is useful for creating watermarks, badges, or composite images where precise positioning is required. Note: The blend-x parameter only affects image overlays. Color overlays always cover the entire image regardless of this setting.

Tool to draw a border around an image. Use when you need to overlay a border without resizing.

Tool to adjust image brightness. Use when you need to modify an image's brightness level (−100 to 100) by supplying your source domain and asset path.

Tool to cancel an Imgix Asset Manager upload session. Use when you need to abort an in-progress or abandoned upload flow and clean up the session.

Tool to opt in to Client Hints. Use when you want Imgix URLs to adapt based on browser headers (Width, DPR, Save-Data).

Tool to close an Imgix Asset Manager upload session after the client uploads to the presigned URL. Use after uploading a file to expedite asset processing. Closing is strongly recommended by imgix.

Tool to specify how many colors to return when extracting a color palette. Use when you need to control palette size and format.

Tool to adjust image contrast. Use when you need to modify an image's contrast level (−100 to 100).

Tool to create an Imgix Asset Manager upload session and return a presigned URL for client-side upload. Use when you need to upload a new image to a storage-backed imgix Source without requiring external hosting. Client performs HTTP PUT of file bytes to the presigned URL, then calls IMGIX_CLOSE_UPLOAD_SESSION to finalize.

Tool to control cropping alignment and behavior using Imgix's 'crop' parameter.

Tool to set or strip output color space/profile on an Imgix image. Use when optimizing compatibility and file size (e.g., cs=strip for smaller metadata).

Download an asset from an Imgix source with optional custom filename. Use this tool when you need to: - Download images or assets from an Imgix CDN source - Force a specific download filename (via 'dl' parameter) - Download assets with special character filenames (via 'dl64' parameter) The asset is fetched from the Imgix CDN and returned as a downloadable file reference. If neither 'dl' nor 'dl64' is specified, the original filename from the path is used.

Tool to embed DPI (dots-per-inch) metadata for print output on an Imgix-rendered image. Use when preparing images for print to set accurate DPI. Supports JPEG and PNG only.

Tool to set device pixel ratio for an Imgix image. Use when rendering at specific display densities to ensure correct sharpness. Example: 'dpr=2&w=500&h=300' doubles resolution relative to dimensions.

Tool to append an expiration parameter to an Imgix URL so it returns 404 after a given time. Use when you want the image URL to stop serving beyond a specific UNIX timestamp.

Tool to control how an image fits target dimensions after resizing. Use when specifying width, height, and fit behavior.

Tool to choose output file format for the rendered asset. Use after specifying the asset path when you need to convert its format.

Tool to force a target aspect ratio on an Imgix image. Use when a specific W:H frame is needed after choosing fit=crop or fit=fill. Example: 'ar=16:9&fit=crop&w=800' yields a 16:9, 800px-wide URL.

Tool to retrieve the status of an Imgix Asset Manager upload session. Use when you need to check the current state (PENDING/CLOSED/COMPLETE/CANCELED) of an upload session for polling or verification after client PUT and/or after closing.

Tool to set output image height in pixels or as a ratio of the source height. Use after constructing an Imgix URL to adjust only height.

Tool to adjust highlight tonal mapping (−100 to 0). Use when preserving detail in bright areas of an image.

Tool to list all Sources for an account. Use when you need to retrieve and paginate through sources with optional sorting and filtering.

Tool to set the base URL prepended to the watermark image path. Use when you need to host watermark assets on a custom domain or CDN.

Tool to set how a watermark fits its target dimensions. Use when applying a watermark and you need control over fitting behavior (e.g., selecting 'scale'). For 'crop', ensure 'mark-w' and 'mark-h' are also provided.

Tool to set watermark height on an Imgix URL in pixels or as a ratio of the watermark source. Use when adjusting overlay height while preserving aspect ratio.

Tool to set pixel padding between a watermark and the image edge or between tiled watermarks. Use after configuring watermark URL and alignment to adjust spacing precisely.

Tool to set watermark width. Use when you need to enforce a watermark's width in pixels or as a proportion. Use after specifying watermark source.

Tool to apply a mask to an image. Use when needing rounded corners, ellipse shapes, or image-based masks.

Constrain the maximum height of an imgix image. This tool applies fit=crop along with the max-h parameter to ensure images do not exceed the specified height. Ideal for vertically-scrolling feeds or galleries where user-uploaded images may have unpredictable heights. Returns a downloadable image URL.

Tool to set the maximum output width on an Imgix URL. Use when you need to cap width (works only with fit=crop). Call after specifying fit=crop on the URL.

Tool to extract a color palette from an image in CSS or JSON form. Use when you need to analyze an image's dominant colors after any transformations.

Tool to set class-name prefix for CSS palette output. Use when customizing CSS selectors for color-palette styling.

Tool to set output quality for lossy formats. Use when adjusting image compression quality for lossy image delivery.

Tool to select a source-image rectangle region in Imgix before other resizing. Use when you need to crop a specific region (x,y,w,h) of the source image.

Tool to rotate an image on Imgix. Use when you need to apply a counter-clockwise rotation (0–359°) with optional mode control.

Tool to control rotation behavior when `rot` is applied. Use after applying a `rot` parameter to choose between pivot (show entire image) or straighten (zoom and crop) behavior.

Tool to render a single-line UTF-8 text overlay on an image. Use when you need simple text captions.

Tool to align a text overlay on an Imgix image. Use when you need to position text by specifying vertical (top/middle/bottom) and horizontal (left/center/right) alignment.

Tool to set text overlay color on an Imgix image. Use when customizing text overlays with CSS color keywords or hex codes.

Tool to choose font family/style for overlay text. Use when customizing text appearance after specifying content. Supports CSS font categories and optional bold/italic flags.

Tool to set outline width around overlay text. Use when styling text overlays on images.

Apply an outline color to text overlays on Imgix images. The text outline must first be enabled using the txt-line parameter (outline width > 0). This action fetches and returns the rendered image with the specified outline color applied.

Set text shadow strength for imgix text overlays. The txt-shad parameter controls the drop shadow intensity (0-10) applied to text rendered on images. Note: This parameter only has a visible effect when combined with text overlay parameters (e.g., txt parameter). Use this action to add depth and visibility to text overlays on images.

Tool to set text font size in pixels. Use when overlaying text and needing precise control over font size. Specify after defining the text content; default is 12px.
