Rewrote three English guides — Every Heartopia Canvas Size, How Image Conversion Works, and Noise & Color Reduction — so they carry the same content as the Japanese versions.
The contact page now states the ways to reach us, what to include in a message, and how we handle what comes in.
Each language's home page now serves an introduction and article links written in that language.

Added import from a screenshot of the game. Feed in a photo of Heartopia's editing screen and the tool works out the canvas position and the size of one square automatically, then imports it directly as pixel art.
Screenshot import detects and removes the game's own guide lines, then builds the pixel art from only the colors actually in use. Fine repeating patterns such as checkerboards survive intact.
The tool now infers the canvas type from the screenshot and suggests candidates. When it cannot tell, it offers none rather than guessing.
Tidied the "Create New" screen so you go straight to choosing a creation method.
Improved detection accuracy so guide lines can be read even on pale designs.

Added an eyedropper tool for picking up a color from the canvas.
Added recommended designs. The public studio listing is now ordered newest first.
The home screen now shows which build you are viewing, so you can tell whether a stale screen is cached. New versions are also detected without a reload.
Fixed artwork being offset by one square on iPhone only, and a mismatch in position between the crop screen and the converted result.
Rebuilt the crop screen layout so one pixel matches its true on-screen size.

The guide library now holds sixteen articles. New this release: choosing and preparing source images, outlines and smoothing jaggies, light and shadow, depicting textures, patterns and tiling, and finishing what you start.
Added a guide index page listing every article, grouped by what you are trying to do.
Added figures to the guides. The conversion method comparison, the four noise reduction levels and the color reduction examples are all real output, produced by running the site's own conversion code.
Redesigned the guide pages: a shared site header and breadcrumbs, a table of contents on each article, a wider reading measure, and a layout tuned for phones.

Image insertion in design edit mode now uses the full conversion flow — conversion method → noise reduction → color reduction — the same steps as regular canvas conversion. Settings apply only to the inserted region.
Added rotation for inserted images (1-degree slider with 90° snapping and ±90° buttons).
Inserted images now default to 100% opacity.
Fixed inserted images not being draggable on smartphones.
Added site introduction content and guides (image conversion tips / noise & color reduction / using designs in Heartopia) plus an About page.

Added free-size canvas mode: create pixel art at any dimensions, beyond the Heartopia-specific canvases.
Improved multilingual search engine optimization (per-language titles, descriptions and metadata).

Stability and security improvements (hardened share page rendering, data protection fixes).
Migrated to a new hosting infrastructure for better speed and reliability.

Launched the core features: image-to-pixel-art conversion, numbered blueprints, block work mode, the pixel editor, and design saving/sharing with a public gallery.
