RO Emblem Studio Guide and FAQ

Emblem editor

Crop to 24×24, draw pixel by pixel, add text layers, manage transparency, and export BMP or GIF.

Animated GIF output

Choose from 60 VFX effects across motion, transform, light, style, impact, and border groups.

Video to GIF

Crop MP4, MOV, or M4V clips to a square and use FFmpeg WASM to create 24×24, 10 FPS GIFs.

Local processing and privacy

Image editing, GIF encoding, and video conversion run in the browser, so source images and videos are not uploaded.

Prompt optimization sends your text description to AI Horde over HTTPS. Do not enter personal or sensitive information.

Five steps

Open the tool, load an image, crop it, refine pixels, then validate and download your BMP.

• Load BMP, JPG/JPEG, PNG, or WEBP images up to 8 MB.
• Adjust the 1:1 crop frame; the preview updates at 24×24.
• Use pencil, eraser, picker, and fill tools for pixel edits.
• Review dimension and magenta transparency warnings before download.
• Place the BMP or GIF in the RO client Emblem folder, then update the guild emblem in-game. The default path is usually C:\Program Files (x86)\Gravity\RagnarokOnline\Emblem, but it depends on where RO is installed.

Auto-save

Canvas data, text layers, and recent colors are stored in browser localStorage. Unexpired work is restored automatically for seven days.

Drawing tools

Use Pencil for direct pixel edits. Eraser and Magic Wand use #FF00FF magenta transparency. Picker samples canvas colors, while Fill supports tolerance.

• Five recent colors are available for quick reuse.
• Undo and redo keep up to 24 steps.
• Tolerance ranges from 0 to 128.
• Grid and fullscreen support precise edits.

Transparent color

#FF00FF is the RO emblem transparency key. Transparent areas use a checkerboard preview, and export warns when magenta may create holes.

How to use it

Set font, size from 5–24px, color, stroke, gradient, and glow; then drag or align each layer horizontally.

• Layers can be selected and adjusted separately.
• Text outside the canvas is clipped.
• Clearing the canvas also removes text layers.

60 VFX effects

Adjust frame delay to control playback. Output checks the 24×24 size and transparent pixels, then quantizes colors above 256.

Note: the effect preview and exported GIF can differ slightly because the preview and export pipelines are not identical. Trust the downloaded file.

• Motion (11): slide, bounce, shake, wave, portal, and more.
• Transform (9): rotate, breathe, spiral, mirror, metaballs, and more.
• Light and color (10): blink, shine, rainbow, neon, freeze crack, and more.
• FX style (10): glitch, pixelate, dissolve, sparkle, VHS, typewriter, and more.
• Impact (10): bass drop, KONAMI, Tetris, Nyan Cat, and more.
• Border effects (10): rainbow, snake, radar, lava, cyber, and more.

Limits and output

MP4, MOV, and M4V are supported up to 50 MB. Clips can be up to 10 seconds and 100 frames; output is fixed at 24×24 and 10 FPS.

Workflow

Upload a video, adjust the 1:1 crop and trim range, confirm the 24×24 preview, then convert. The first conversion downloads and verifies an approximately 31 MB FFmpeg WASM core.

Workflow

Describe the image, choose one of 28 styles, optimize and copy the English prompt, generate an image with FLUX, Perchance, ChatGPT, Gemini, or another service, then import it back into the tool.

Prompt optimization defaults to an outlined subject on a white background, helping the image keep a clear silhouette after it is reduced to 24×24.

The tool links to FLUX.1-schnell, Perchance Image Generator, Perchance Character Generator, ChatGPT, and Gemini. FLUX may need a Hugging Face login to avoid quota limits; Perchance can be used as a no-login fallback.

Example

Before (Chinese description): Ragnarok Online 遊戲中的 Poring 拿著劍與頭盔，擺出戰鬥姿態

After (English prompt): Ragnarok Online game a Poring holding a small sword and wearing a metal helmet in a combat pose, European storybook animation icon, simple bold shapes, high contrast, thick clean outline, flat color blocks, centered on a plain white background.

Different AI models such as FLUX, Perchance, Gemini, and ChatGPT interpret the same prompt differently, so compare several platforms when the result matters.

Data and limits

Text descriptions are sent to AI Horde. Successful and failed requests both have a 30-second cooldown. The first protected prompt optimization may require Cloudflare Turnstile verification.

Repeated prompt optimization in a short period may be temporarily blocked or hit free usage limits. Wait and retry later, or reconnect through a different network or VPN.

• The tool does not generate or upload images directly; the built-in entry point opens third-party services such as Hugging Face.
• A square 768×768 generated image is recommended.
• You are responsible for third-party AI terms, licensing, and generated content.
