SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Preparing digital images for print requires correct DPI metadata and physical dimensions, and doing this manually risks re-compression, quality loss, or silently stretched low-resolution files. This Skill calls the Pixazo Image DPI API to re-tag images at a target DPI and physical print size without decoding or re-compressing PNG/JPEG pixels. ## Core Features & Use Cases - Lossless DPI re-tagging: Set DPI between 72 and 1200 (default 300) while keeping the source format and original pixels intact for PNG and JPEG. - Physical size presets: Target standard print sizes like 4x6, 8x10, A4, A3, or 24x36, or specify custom width_in/height_in dimensions, with optional upsampling via allow_upsample. - Quality guardrails: Images with too few pixels for the requested size are rejected rather than silently stretched, and non-native outputs return as TIFF unless a format is specified. - Use Case: A designer needs a photo prepared as an 8x10 print at 300 DPI. The agent sends the image URL to the API with dpi 300 and size 8x10, then returns the print-ready TIFF URL. ## Quick Start Ask the agent to prepare an image URL for print at 300 DPI in 8x10 size using the Image DPI API.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I change an image to 300 DPI for printing?▼

Send the image URL to the Pixazo image-dpi endpoint with dpi set to 300. For PNG and JPEG the metadata is re-tagged without decoding or re-compressing the pixels, so image quality is preserved.

What print sizes does the Image DPI API support?▼

It supports presets including 4x6, 5x7, 8x10, 11x14, 12x18, 18x24, 24x36, a5, a4, a3, a2, letter, and tabloid. You can also pass custom width_in and height_in values instead of a preset.

Does changing DPI reduce image quality?▼

No for the native re-tag operation: PNG metadata is copied and pixels are never decoded or re-compressed. Only operations beyond the native re-tag, such as resizing to a physical dimension, produce a TIFF output unless you specify another format.

What happens if my image resolution is too low for the print size?▼

The API rejects the request rather than silently stretching the image. You can pass allow_upsample to permit enlarging when you accept the quality trade-off.

Why did the Image DPI API return a 401 error?▼

A 401 means the API key is missing or invalid. Get a fresh key at https://api-console.pixazo.ai/api_keys and pass it in the Ocp-Apim-Subscription-Key header.
