Comic page layout / 03
Turn a stack of panels into real comic pages. Panel Forge lays out the page for you, choosing a design that fits every picture without cutting a single word. Add hand-drawn sound effects and bold titles, then export a print-ready book as PNG, PDF or CBZ.
Start from an episode or from your own pictures. The layout is done for you; the fun parts are yours.







Layout, sound, titles and print — everything a comic page needs, in one place.
Open an episode and Panel Forge looks at the shape of every picture, then picks a page design that fits them all. Your balloons are never cropped. Prefer another arrangement? Choose from dozens more.
Hundreds of hand-drawn effects — BOOM, SPLASH, THUD, ZZZAP — in styles from ink to halftone to manga. Drop one on the art, turn it, scale it, let it burst across the panel border.
Choose how many panels, then pick a design: balanced grid, hero focus, cinema strips, mosaic, diagonal and more. Every panel stays fully editable.
Type your title and choose from dozens of drawn lettering families — prismatic, halftone, newsprint, gouache. It lands on the page as artwork, sharp at any size.
Give a scene room to breathe. Panel Forge fits the panels to the page and you add the noise exactly where it happens.
Before you export, Panel Forge tells you the page size, how sharp each picture is and how large the words will be on paper — so nothing comes back from the printer as a surprise.
Load your images and click to place them in panels. Drag inside a frame to crop, scroll to zoom.
A closer look at what you work with every day.




The page is composed first and filled afterwards, which is the order comics are actually drawn in. Every count below is a count of things that exist on disk and are checked by a test, not a rounded-up brochure figure.
Phone 9:16, phone 16:9, US comic, A4, square and WEBTOON. Choose exactly how many panels the page carries, anywhere from one to nine.
Three paper colours sit on a shelf beside the colour picker: click one to put it on the page, right-click to save the current colour in its place. They are still there for the next comic.
Number, pattern, composition, shape, apply. There are ten patterns for every panel count — Balanced Grid, Hero Focus, Dynamic Split, Cinema Strips, Vertical Columns, Mosaic Flow, Editorial Stair, Focus Rail, Offset Rhythm and Diagonal Story — which is ninety combinations in all. Each pattern crosses with five overlap modes, so a single panel count offers fifty overlapping variants on top of that.
Choose the shape they share before generating: straight, rounded, ellipse, trapezoid, oblique, triangle, hexagon or jagged. Apply a pattern to the page you are on and keep the pictures already in it, or start a fresh page at the chosen count. Save the whole combination into ★ My Layouts — by button or by right-clicking the thumbnail — and it is waiting at the next launch.
Change any one panel's shape afterwards, slide it by the MOVE handle at its top-left corner, resize it from any of eight handles, and push it through the stack one level at a time or straight to the front or the back.
Irregular panels are selected from the part you can actually see, even where their bounding rectangles overlap each other. Right-click gives shape, order and delete; the Delete key removes the selected panel without disturbing a text field you happen to be editing. Add loose panels, or duplicate one, for a layout that matches nothing in the list.
The picture under the cursor drops into the panel under the cursor, and the rest go on to fill the empty ones. Inside a frame, drag the photograph to move the crop and roll the wheel to zoom it up to eight times, holding the point under the cursor still — the panel does not change size, and the picture is never stretched, waved or fish-eyed, not even in a very narrow panel. Alt and drag moves the panel instead, and the Inspector puts zoom and position back to 100%.
The Images tab lists only your own photographs, with thumbnails, in alphabetical order, marking the ones already used and the ones that have gone missing from disk. Under the page list there is a tray: drag a picture straight onto the panel that should have it, or drop it over another picture to change the order they fill the empty panels in.
Eight visual styles — Artist Ink, Clean Graphic, Studio Select, Classic Halftone, Manga Mono, Editorial Duotone, Ligne Claire Pop and Bold Flat Color — in ten categories covering impact, explosions, movement, weapons, energy, liquids, fire, voice and nature. Every one of the 688 variants is its own HD picture with real transparency, not a mask laid over a drawing at display time, and each is checked automatically for its transparent and opaque areas.
Beside them: 165 textless graphic shapes in eleven families, from impact bursts and ink splatters to shockwave rings, caption plates and smoke; and twelve complete stamps with the lettering drawn into the illustration itself. Your own PNG, WEBP or JPG effects drop straight onto the tab and then move, rotate, resize, duplicate and export exactly like the built-in ones — the project remembers where they came from and reloads them when you open it again.
PNG at the final resolution — the page you are on, or every page numbered into a folder in one go. Projects are saved as a single .comic-native.json file, and saving remembers which file it was, so Ctrl+S writes over it without asking where.
There is also a standalone HTML viewer: the exported page keeps all its panels, crops, effects and outlines, and clicking a panel opens the full source photograph, uncropped, in the outline style you chose for it.
spine = pages / PPI, plus the boards on a hardback and whatever the binding addspHYs chunk), so a printer opens them at the right size rather than at 72 DPIdocs/coperti.md, read out of printers' specification pages and the official GS1, Diamond, USPS and Copyright Office PDFs — with nineteen contradictions between sources written down rather than smoothed over. Nothing in this tab is inventedEvery effect is hand-drawn, with a transparent background, in styles that match any kind of comic — plus 299 graphic shapes for speed lines, impacts and explosions. Search by sound, filter by style, and drag it straight onto the art. Have your own? Import any PNG, WEBP or JPG.
A slider that cannot land on the number you want, a window that closes over an hour's work, a library that scrolls off the bottom of the screen. None of them are features anybody advertises, and all of them are why an editor is pleasant or exhausting to sit at.
Border thickness, the gutter between panels, image zoom, crop position, effect size and rotation, PNG opacity and the four exact-geometry boxes all carry − and + beside them.
The reason is arithmetic: across a range of five hundred, one pixel of dragging is worth several units, and the last value cannot be reached by dragging at all. A cursor alone could never land on a particular number. A button can.
The title bar carries a yellow dot and the filename for as long as the page on screen differs from the one written to disk. Closing the window, Alt+F4, Open and New all ask first, with three answers: save, carry on without saving, or cancel. Choose save and then cancel the file dialog and nothing closes — the question simply comes back.
A project file damaged on disk — written half-way, or edited by hand — no longer brings the editor down with it. Impossible values are put back at load, and the program tells you how many it had to correct.
The interface is written in Rust with eframe and egui and rendered through the GPU. There is no HTML, no React, no Tauri and no WebView anywhere in the project. It runs out of a folder you can copy where you like, with its assets sitting beside the executable — and the Sentiora mark is the icon of the window, of the taskbar button, and of the file itself in Explorer.
Card size is yours to set — S, M, L or XL — and the cards span exactly the width of the row while keeping the illustration's proportions, so no empty bands are left around the drawing. The panel widens by dragging its edge, nearly to the edge of the sheet, and it tells you how many effects fit on a row at the width you have chosen.
Categories are a row of small buttons, each carrying its own count, with just that category underneath — not ten collapsible sections where opening one throws the rest below the bottom of the window. Panel widths, card sizes, tray thumbnail size, saved layouts and favourites are all kept in your Windows profile and come back at the next launch.
Drag the background, or hold the middle mouse button, to slide the whole page around. Ctrl with the wheel, or Ctrl and drag, scales the workspace between 25% and 600% while holding the point under the cursor still. Ctrl+0, Center the page, or a double-click on the background puts it back to 100%.
Together they take you from a written story to a printed book: Comic Pipeline makes the pictures, ComicBubble adds the words, Panel Forge builds the pages. Each one passes your work to the next with a single click. But every program also works completely on its own — already have your art? Start with ComicBubble. Already lettered? Go straight to Panel Forge. You only buy what you need.
Paste your script or book. It plans every panel, keeps your characters looking the same, and creates the images with the AI service you choose.
586 hand-drawn balloons in 15 styles and a dozen comic fonts. Your dialogue lands on each panel, beside the right character.
Automatic page layouts, 708 drawn sound effects in 10 packs, 299 graphic shapes and 56 title styles. Export PNG, PDF or CBZ.
The window speaks English and thirteen more languages, switched from a list and remembered. It installs like any Windows program or runs from a folder, needs no account and no internet to work, and keeps your pages in a single project file you can carry to another computer. Native code drawn by the graphics card: it opens in a moment and stays quick on long books.
