Preview & Export¶

Preview¶

Click "Preview Handwrite Image" in the top bar and the result appears in the right column.

Preview renders only the first page — the point is to check your parameters fast without waiting for the whole document.
When the text runs to several pages, page controls appear below the preview: "Previous", "Next", and "Page x / y".
After changing any parameter you must click preview again. The preview does not re-render on its own.

Click "Generate Full Handwriting Image" and the backend renders every page to PNG and packages them as images.zip.

The archive contains one PNG per page, in order.
This is the most direct way to get all the pages — useful if you want to lay them out yourself or drop them into another document.

Click "Generate PDF" and the backend merges every page into a single images.pdf. No more pasting images into a document by hand.

Which one?

Inserting into Word, or controlling page order yourself → zip. A file you can print or send as-is → PDF.

A page estimate appears below the text area, so you can see roughly how many pages you are heading for while you type.
On handwrite.14790897.xyz a single run renders at most 10 pages; anything beyond that is truncated. Both the estimate and an over-limit dialog warn you in advance. A self-hosted instance has no such cap, but it is still subject to resource limits.

Cooldown — 3 seconds between runs, with a countdown on the button.
Queueing — the backend handles a limited number of jobs at once. When the queue is full a wait countdown appears, telling you roughly how long.
Progress — generation state is pushed over a WebSocket; if that fails the client falls back to polling, and the interface looks the same.
Failures — if rendering errors out, the task ends as failed with an error message. On a self-hosted instance the details are in the container logs:
