## MCP tools (6)

### `remove_background` (~189 tokens)

Remove background

Cut the main subject out of a photo and make the background transparent (on-device AI — the image never leaves this computer). Saves a transparent PNG and returns its path plus a small preview. Use for "remove the background", "cut out", "transparent background", "누끼", product and profile photos. The PNG is lossless and large; to make it smaller, pass it to `compress` with format webp or png (jpeg cannot be transparent). The first call downloads a ~98 MB model once.

Input parameters:

- `input_path` (string, required): Image file to process (jpg, png, webp, avif, gif, tiff; heic on macOS). Absolute, ~/…, or relative to the working directory.
- `output_path` (string): Where to save the PNG. Default: "<name>-cutout.png" next to the input. Existing files are never overwritten.

### `compress` (~318 tokens)

Compress image

Make an image file smaller with little visible quality loss, on-device (same encoders and defaults as ruah.tools). Saves a new file and reports the size before and after; the original is never changed. Formats: keep = same format as the input; webp = usually the smallest and keeps transparency; avif = smaller still, slower to encode; jpeg = photos only, transparency becomes white; png = lossy palette compression that keeps transparency (or lossless=true for exact colours). Prefer webp unless the user needs a specific format. This is also the tool for converting between formats ("convert to WebP/AVIF/JPG/PNG"): set `format`. To change the pixel dimensions, use `resize` instead (it can change the format in the same step).

Input parameters:

- `format` (string): Output format: keep = same as the input; webp = usually smallest, keeps transparency; avif = smaller still, slower; jpeg = photos only, transparency becomes white; png = keeps transparency. Default k…
- `input_path` (string, required): Image file to compress. Absolute, ~/…, or relative to the working directory.
- `lossless` (boolean): png only: keep exact colours (bigger files).
- `output_path` (string): Where to save. Default: "<name>-compressed.<ext>" next to the input. Existing files are never overwritten.
- `quality` (integer): 1–100 for webp/avif/jpeg. Default 80 (visually near-identical, much smaller).

### `resize` (~355 tokens)

Resize image

Change an image's pixel dimensions, keeping its proportions, on-device (same high-quality resampler and encoders as ruah.tools). Give exactly one of max_side (the longest side in pixels — e.g. 1920 for web pages, 1080 for social posts, 640 for thumbnails) or percent. It never enlarges unless allow_upscale is true. Saves a new file and reports the size before and after; the original is never changed. The output is also compressed with the same format/quality options as `compress`, so "make it 800px and WebP" is one call.

Input parameters:

- `allow_upscale` (boolean): Allow max_side to make the image larger than the original. Default false.
- `format` (string): Output format: keep = same as the input; webp = usually smallest, keeps transparency; avif = smaller still, slower; jpeg = photos only, transparency becomes white; png = keeps transparency. Default k…
- `input_path` (string, required): Image file to resize. Absolute, ~/…, or relative to the working directory.
- `lossless` (boolean): png only: keep exact colours (bigger files).
- `max_side` (integer): Fit inside this many pixels on the longest side.
- `output_path` (string): Where to save. Default: "<name>-resized.<ext>" next to the input. Existing files are never overwritten.
- `percent` (number): Scale to this percentage of the original (1–100; to enlarge, use max_side with allow_upscale).
- `quality` (integer): 1–100 for webp/avif/jpeg. Default 80 (visually near-identical, much smaller).

### `crop` (~481 tokens)

Crop, rotate or flip image

Cut an image down to an aspect ratio or an exact region, and/or turn it by quarter turns or mirror it, on-device (same tool as ruah.tools/crop: whole pixels moved, never resampled). aspect_ratio keeps the largest centred area of that shape (e.g. "1:1" for a square profile picture, "16:9" for a video thumbnail, "4:5" for a portrait post). box keeps an exact region, in pixels of the input as it is shown (upright). rotate and the flips work alone or together with either. Saves a new file and reports which region of the input it kept; the original is never changed. To change the pixel size use `resize`; to change only the format or file size use `compress`.

Input parameters:

- `aspect_ratio` (string): Width:height of the result, e.g. "1:1", "4:5", "3:2", "16:9". Keeps the largest centred area of that shape (after rotate). Give this or box, not both.
- `box` (object): Exact region to keep, in pixels of the input as shown (upright), measured before rotate and flips. Give this or aspect_ratio, not both.
- `flip_horizontal` (boolean): Mirror left↔right (after rotating).
- `flip_vertical` (boolean): Mirror top↔bottom (after rotating).
- `format` (string): Output format: keep = same as the input; webp = usually smallest, keeps transparency; avif = smaller still, slower; jpeg = photos only, transparency becomes white; png = keeps transparency. Default k…
- `input_path` (string, required): Image file to crop. Absolute, ~/…, or relative to the working directory.
- `lossless` (boolean): png only: keep exact colours. Default true; false makes a smaller palette PNG.
- `output_path` (string): Where to save. Default: "<name>-crop.<ext>" next to the input. Existing files are never overwritten.
- `quality` (integer): 1–100 for webp/avif/jpeg. Default 90, like the web crop tool.
- `rotate` (integer): Turn clockwise by this many degrees: 90, 180 or 270 (-90 turns anticlockwise). Default 0.

### `upscale` (~462 tokens)

Upscale image (AI)

Enlarge an image 2× or 4× with on-device AI super-resolution (the same models as ruah.tools/upscale — the image never leaves this computer). Unlike `resize`, it redraws detail and crisp edges instead of stretching pixels into blur. Made for small or low-resolution images: icons, thumbnails, old web images, small product shots. Saves a new file and returns its path plus a small preview; the original is never changed. The result is limited to 16.8 megapixels (4096×4096): ×4 fits inputs up to about 1000×1000, ×2 up to about 2000×2000. To make an already large photo bigger, use `resize` with allow_upscale. Time grows with the output: small images take seconds, ×4 of 1000×1000 a minute or more. Transparency is kept: a transparent logo, icon or cut-out comes back transparent, with no dark fringe (save as png, webp or avif to keep it). The first ×2 call downloads an 8 MB model once, the first ×4 call 55 MB.

Input parameters:

- `format` (string): Output format: keep = same as the input; webp = usually smallest, keeps transparency; avif = smaller still, slower; jpeg = photos only, transparency becomes white; png = keeps transparency. Default k…
- `input_path` (string, required): Image file to upscale (jpg, png, webp, avif, gif, tiff; heic on macOS). Absolute, ~/…, or relative to the working directory.
- `lossless` (boolean): png only: keep exact colours. Default true; false makes a smaller palette PNG.
- `output_path` (string): Where to save. Default: "<name>-upscaled-x2.<ext>" (or -x4) next to the input. Existing files are never overwritten.
- `quality` (integer): 1–100 for webp/avif/jpeg. Default 90, like the web upscaler.
- `scale`: 2 = twice the width and height (default — quicker, and enough for most images); 4 = four times, for genuinely tiny sources.

### `strip_metadata` (~257 tokens)

Remove metadata

Remove hidden metadata from an image before sharing it, on-device (same cleaner as ruah.tools): EXIF (GPS location, camera and device, date taken), XMP, IPTC, comments, embedded thumbnails and extra data such as motion-photo video. JPEG and PNG are cleaned losslessly — only the image data and its display settings (colour profile, orientation) are copied, not re-encoded — so the photo looks exactly the same. Other formats (HEIC from an iPhone, AVIF, GIF, …) are rebuilt from their pixels with no metadata at all: WebP stays WebP, images with transparency become PNG, photos become JPEG (quality 92). Saves a new file; the original is never changed. The result lists what was removed (e.g. a GPS location) and what is left — no need to check with other tools. Use for "remove EXIF", "strip GPS / location", "clean metadata before posting".

Input parameters:

- `input_path` (string, required): Image file to clean. Absolute, ~/…, or relative to the working directory.
- `output_path` (string): Where to save. Default: "<name>-clean.<ext>" next to the input. Existing files are never overwritten.
