Frequently asked questions

Use Editor to draw pixels, Sprite to organize video/GIF frames, Pixelizer to change the pixel style of images or 3D, and the 3D workbench to generate or paint a model. The tools have different purposes and export behavior.

Every feature except image-to-3D generation is free, including Pixelizer: importing images or 3D models and adding weapons or equipment use no credits. Credits are used only for image-to-3D generation: 80 credits for one image or 100 for 2–4 views. To generate 3D, use a Pro, Max or Ultra pass or your own Tripo API key (no SPRITFY credits are used; Tripo bills your own Tripo account). Pro grants 700, Max 2,000 and Ultra 7,500 credits every month, without rollover. Credits of a failed or cancelled generation are returned automatically. See plans for your balance and the actual checkout price.

Local editing and conversion, including importing files into Pixelizer, can start without signing in. Signing in is required to keep work in your account (including My works), to export Pixelizer results, and for image-to-3D generation (also when you use your own Tripo API key). Signing in never publishes your work: artworks saved to My works are visible only to you.

Ordinary image/video processing, 3D pixelization and texture editing run in the browser. Image-to-3D sends its input to the server and generation service; account synchronization and artwork saving upload the relevant files. Editor AI requests go to the connected service. Not every feature is entirely offline.

Use an up-to-date browser such as Chrome, Edge, Firefox or Safari. Supported video codecs and available memory affect which files can be processed. For large models or long animations, start with a short segment on a desktop. On mobile, collapse panels to make room for the canvas.

Korean, English and Japanese are available from the language menu. Tools and documents link to the selected language’s routes. Changing language does not convert the source file to another format.

Start with the default 3D model-to-pixel preset with outlines. Set pose and camera in 3D Input, then PIA long side and color count, then outlines. Choose a source-appropriate preset and change one setting at a time.

Preserve detail is the default and cleans boundaries while retaining small features. Remove detail more actively cleans one-pixel protrusions and irregularities. Turn Draw outline off to compare cleanup alone. Inspect eyes, fingertips and hair tips against the original.

Color outlining, 25% darkness and no light direction. Lines use a darker color related to the nearby interior. Darkness sets their contrast; light direction adjusts the lighter and darker sides. Choose a solid line color for a uniform outline.

It is the transparency cutoff used to determine a shape’s boundary. The outline default is 120. Higher values can exclude faint edge pixels; lower values can include more of them. It does not control image brightness or line color. Check thin or translucent features when changing it.

No. It chooses the reference frame for extracting a palette and does not reduce the animation to one frame. If colors used only by a weapon or an alternate pose disappear, compare the palette reference and the complete animation.

No. The long side in PIA/downscaling controls actual pixel resolution. Export scale enlarges finished pixels by an integer factor. Internal 3D grid height is automatically fitted to the memory budget. A larger export scale does not create new artistic detail.

Open GLB or glTF in the 3D workbench. Select external .bin and texture files with a glTF. Pixelizer also accepts VOX. A self-contained GLB is convenient for avoiding missing resources. Importing a model is separate from generating a new one from an image.

Sign in, choose the input image(s) on the 3D Creator page, then choose "Credits" or "My Tripo key" in the 3D generation card and start. Generation uses the SPRITFY server and the external generation service Tripo. Download the finished model or keep it in My 3D works, check its texture, orientation and rig, then send it to Pixelizer.

Yes. Once signed in, you can choose your own Tripo API key instead of credits for each generation, which helps when you have no way to pay for a pass, for example outside Korea. Create a key on the Tripo Console’s "API Keys" page (https://developers.tripo3d.ai/en/keys), then choose "My Tripo key" in the generation card of the 3D Creator page and enter it. The key starts with tsk_ and is shown only once when it is created, so copy it right away; a value starting with tcli_ is the Client ID, not the key. No SPRITFY credits are used; Tripo bills your own Tripo account at Tripo’s prices. The key is saved only in this browser and can be removed at any time. It is sent over HTTPS only to start or resume a generation, or when you press the optional "Check key" button (which only looks up the Tripo balance and stores nothing); the server keeps it in memory for that job (or that single check) and never stores it in a database or logs. Sign-in is still required, and results are saved to My 3D works as with credits.

The current brush edits color textures. It supports surface/UV painting, picking colors, smoothing noise, undo and texture replacement. Sculpting geometry, filling holes and making a new UV unwrap require a separate modeling step. Use material color controls if no editable texture exists.

Check the file rig first if a skeleton already exists. Use automatic rigging and joint markers when a new skeleton is needed. Wide sleeves and skirts can stretch during motion, so inspect several frames and adjust joint positions and motion amounts.

Rotation, viewing elevation and direction count at the top of 3D Input configure rendering cameras. Rig alignment angle sets the facing reference used by rigging. A model sent from the workbench uses its prepared orientation; do not automatically add another 90-degree turn.

Reduce arms, legs, torso and head motion separately. The default reference is the file’s rest pose; clip mean and first frame are alternatives. Motion amounts reduce movement toward that reference. Enable In place to remove horizontal travel when appropriate, then check jumps and intended displacement.

A sprite sheet is one PNG containing multiple frames. Pixelizer’s Sprite button and Ctrl+S export all final frames. If the PNG itself contains only one picture, check output frame count, clip and direction settings. Use ZIP when you need one PNG file per frame.

For identifiable 3D groups, directions form rows and motion frames form columns. Four directions with eight frames produce an 8×4 grid containing 32 images. Other animations use an automatic grid with columns×rows in the filename. Complex branches or an already packed image follow the final output structure.

Use GIF for playback and sharing, a PNG sheet for region-based animation, and ZIP for individual PNGs to arrange elsewhere. A PNG sheet does not automatically include game-engine animation setup or FPS metadata; record timing separately.

Sprite provides extraction, frame selection and order, reverse/ping-pong, range trimming and duplicate removal. Chroma key and corner-connected removal can clean backgrounds. Increasing tolerance can also remove similar-colored clothing or eyes, so inspect the subject.

Sprite’s sheet importer splits an image into frames using the configured grid or cell size. You can also merge separate images. Use Editor for direct pixel edits. A PNG sheet does not contain the original layer structure, so it cannot restore those layers automatically.

Editor PNG saves the current frame; its sheet and GIF use the selected animation range. Pixelizer Sprite packs the complete processed output and also offers GIF and individual PNG ZIP. Keep editable work too when you need layers, nodes or source files later.

Saved on this device means the work is in this browser’s storage. Saved to account means the relevant upload has completed. Confirm account storage before switching devices. Clearing browser data or closing a private session can affect local work.

Pixelizer retains source files and node settings locally, with up to 24 works and 64 MB per file. Automatic account sync targets sources of 24 MB or less. User motion GLB libraries are separate. Source work, processing presets and motion libraries are distinct items.

The workbench automatically keeps models and edits in My 3D works. Sign in and use Save work to copy the current work to your account. There is a 64 MB per-file limit; check completion status. Download an actual GLB rather than only keeping a temporary generation URL.

Motion range and frame count affect memory use. Internal resolution is automatically based on the rest pose. For traveling clips, use In place when appropriate and try fewer frames. Save before refreshing an old tab. If the error persists, send the model format, clip, settings and full error text.

An old tab can request an earlier asset and show a dynamic-module loading error. Save any work you can before refreshing. If it continues, report the page URL, browser version and error. Avoid clearing site data before backing up local work.

Email [email protected] with your sign-in email and request. Include payment time/order identification for billing, or device and save status for work issues. Refunds of passes paid earlier with PayPal can also be requested at this address. Do not send passwords, login tokens, AI API keys, your own Tripo API key or full card numbers. See Contact for the details to include.

B pencil, E eraser, G fill, I eyedropper, L line, U rectangle and O ellipse. Ctrl+Z undoes changes; redo is also supported. Finish editing a text or number field before switching tools with a keyboard shortcut.

You connect a supported AI service and API key. Requests and relevant inputs are sent to that service, whose terms and usage charges may apply. This is separate from the non-AI Pixelizer algorithms running in the browser.

It supports outputs including PNG, JPG, WebP, BMP, GIF and ICO, and batch conversion. Quality controls depend on the format. Check background handling for formats such as JPG that do not support transparency. Use Sprite or Pixelizer to preserve and edit animation frame by frame.
