🎚️ Binarization bands

Divide the output into discrete luminance bands instead of a single threshold. A bandsScale parameter controls the distribution curve so bands can be weighted toward highlights or shadows.

📈 bandsScale (metaball)

Applies the same non-linear distribution control to the metaball renderer.

🔍 Supersample in preview

Renders the preview at a higher internal resolution before downscaling, reducing aliasing on fine patterns.

💾 Export dialog persistence

Scale, format, and quality choices are remembered between sessions.

🔄 Cancel / resume auto-renewal

Buttons now show a loading state while the request is in flight, preventing double-clicks.

⚠️ Incomplete subscriptions

Now redirect to the Stripe Billing Portal to complete payment, rather than showing an error.

🔵 Metaball low decay rendering

Rendering logic was corrected and default values were updated to decayRate=8 and threshold=0.1.

🚫 Duplicate subscriptions

A race condition allowed duplicates to be created. The checkout flow now blocks new sessions when an active paid subscription already exists.

🖥️ Subscription tab flicker

This was caused by double data fetching on load and has been consolidated into a single fetch.

🖼️ Thumbnail generation

This silently failed due to a stale closure capturing an outdated model reference. It was fixed by using refs for model and settings.

🤖 Background remover

This threw image load errors when an Object URL was revoked before the image finished loading.

📸 Snapshots component

Multiple bugs were fixed, including an incorrect sourceBlob type, revoked Object URLs, and records not being cleaned up when IndexedDB writes failed.

🖋️ New logotype

SVG was added to the navbar and footer.

✨ Animated logo spinner

Uses spring physics via anime.js for a smooth, natural-feeling entrance animation. A minimum loading duration ensures the animation completes before the studio appears.

🎨 Favicon and app icons

Updated to the new brand design.

✏️ Stippling renderer

Distributes dots based on image luminance using a relaxation algorithm, producing an irregular, hand-engraved look distinct from the regular grid renderers.

🔲 Floyd-Steinberg dithering

Propagates quantization error to neighboring pixels for smooth tonal gradients in binarized output. The result shows significantly less banding than threshold-only binarization.

📐 SVG direct mode export

An alternative SVG output path writes shapes without going through the canvas, improving compatibility with Illustrator, Inkscape, and laser cutter software.

🔢 Live dot count

Updates in real time as you adjust parameters, alongside the canvas pixel dimensions.

🔒 Stippling stability

Deep-cloned grid points prevent state mutation, making undo/redo reliable when switching renderers.

↩️ Undo/redo

Step back and forward through every parameter change with Cmd/Ctrl+Z and Cmd/Ctrl+Shift+Z.

🔍 Diff highlighting

Any value that differs from its default is highlighted, so you can see at a glance what has been changed in each section.

↔️ Grid stretch

Independently scale the halftone grid on the horizontal and vertical axes for non-uniform patterns.

🔀 Image flip

Horizontal and vertical flip were added to the cropper dialog.

🌓 Contrast adjustment

Added to the image adjustments panel.

🎨 Canvas background customization

Choose a solid color or a checkerboard transparency pattern.

🎚️ Quantization mix parameter

Blend between the original and quantized input for subtler posterization.

🔑 License refresh

Manually sync entitlements from the account page without signing out.

🏷️ Slider labels

Fixed wrapping to a second line on narrow panels.

💎 Pro subscription

Monthly and yearly plans unlock unlimited AI background removal and other premium features. Manage your plan from the account tab.

🛒 Spot purchase

A one-time payment option for users who prefer not to subscribe.

💳 Card and Link

Payment methods supported at checkout.

🏷️ Promotion codes

Enter a discount code at the Stripe checkout page.

▶️ Checkout session resume

If you sign in mid-flow, you are automatically returned to where you left off.

⬆️ Upgrade prompts

Integrated into the batch processing and export dialogs.

⚙️ Subscription management

Cancel, resume auto-renewal, and downgrade flows are now clearly separated with loading states on each action.

🧾 Automatic tax

Collected at checkout via Stripe Tax.

⚡ WASM Gaussian blur

Blurs are computed in a WebAssembly module, providing a true Gaussian blur instead of relying on the CSS blur approximation used previously.

⚙️ Environment settings panel

Choose between CSS blur, WASM blur, and other blur methods. The selected method persists between sessions.

🌐 Language switcher

Change the interface language without navigating to a settings page.

🔵 Blur radius as sigma

Now treated as standard deviation rather than pixel radius, giving more predictable results across different image sizes.

🔄 Quota fetching

Usage data stays fresh without redundant network requests.

🤖 AI background removal

Remove the background from any image with one click. The result is returned as a transparent PNG ready to halftone.

📡 Real-time job status

A progress indicator updates live as the server processes your image.

↔️ Before/after comparison slider

Drag to reveal how much of the background was removed.

📊 Monthly usage display

Remaining credits, next reset date, and billing period are shown clearly in the account panel.

🔄 PWA manual update

When a new version is available, a prompt lets you choose when to apply it rather than reloading automatically.

🔢 SVG export precision

Controls the number of decimal places in path coordinates to reduce file size.

📊 Usage quota

The UI clearly shows how many credits remain and when they reset.

👤 User accounts

Sign in with email/password, phone number (OTP), or Google OAuth. A welcome dialog is shown on first sign-in.

☁️ Preset cloud sync

Presets saved while signed in are stored in the cloud and automatically available on any device.

🧑 User avatar

Displayed in the navbar when signed in.

↺ Section reset buttons

Quickly restore any section to its default values without touching other settings.

🔲 Standalone quantization panel

Quantization controls are now directly accessible in the sidebar without going through a sub-menu.

🛡️ Turnstile CAPTCHA

Integrated into all auth flows to prevent spam and credential stuffing.

⚡ Blob caching

Previously processed image data is reused instead of recomputed, making preset switching and snapshot loading noticeably faster.

🔬 Advanced mode

A toggle that reveals hidden parameters across all panels, including scale, radius factor, alpha blending, and rendering internals, for granular control beyond the standard UI.

🌀 Displacement settings panel

Warp the halftone grid using 2D noise, with displacement type, scale, amount, and seed controls for organic, hand-printed distortion.

⚫ Metaball binarization toggle

Switch the metaball renderer to a hard binarized output instead of a smooth gradient.

🌍 9 new languages

French, Portuguese, Italian, German, Spanish, Russian, Chinese (Simplified), and more were added.

📱 PWA support

Install the app to your home screen via the browser prompt. The app launches in standalone mode and works offline.

📐 Bounding mode

Controls how output dimensions are calculated relative to the source image.

💳 Pricing page

Added with plan details and subscription options.

🔢 SVG numeric precision

Lower values produce smaller files with negligible visual difference.

⬇️ Download button redesigned

SVG and PNG are now clearly separated actions in a popover menu.

⚡ Tile-based pixel renderer

Large images are processed in tiles so you can cancel a render mid-way without freezing the browser.

🌊 Sampling effects panel

Layer wave, noise, and other effects directly on top of any halftone pattern. Includes wave shift and frequency controls.

🔲 Quantization and dithering options

Posterize the input image before halftoning, with Bayer matrix dithering patterns from 2×2 up to 16×16.

Rotate the source image in 90° steps before applying the crop.

⏳ Download spinner

Shown during export so it is clear when a file is being generated.

🔧 Toolbar layout reorganized

Grid and pixel renderer shortcuts are directly accessible without opening a sub-menu.
