Comic page layout / 03

SentioraPanel
Forge

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.

Version 3.0.6 / 14 languages / Windows
A full page in one clickFive panels laid out for you, sound effects dropped on top.

From loose panels to a printed book, in seven steps.

Start from an episode or from your own pictures. The layout is done for you; the fun parts are yours.

Step 1: Bring your panels.
Step 1 · Bring your panelsOpen an episode from ComicBubble, or load your own images — PNG, JPG or WEBP — and click to drop them into the panels.
Step 2: Get the page laid out.
Step 2 · Get the page laid outPanel Forge looks at the shape of every picture and picks a page design that fits them, without cutting a single balloon. Prefer another? Choose from dozens of designs for one to nine panels.
Step 3: Fine-tune the panels.
Step 3 · Fine-tune the panelsDrag inside a frame to move the picture, scroll to zoom, change borders and gutters. Every number has a minus and a plus, so you land exactly where you want.
Step 4: Add the sound.
Step 4 · Add the soundPick from 708 hand-drawn sound effects in 10 packs, drop them on the art, then turn and scale them until the page feels loud.
Step 5: Add a title.
Step 5 · Add a titleType your title and choose one of 56 drawn lettering styles. It lands on the page as artwork, sharp at any size. Make a cover with bleed and spine measured for the printer.
Step 6: Check it for print.
Step 6 · Check it for printBefore you export, it tells you the page size, how sharp each picture is and how large the words will print — and warns you in red if something is too small.
Step 7: Export your book.
Step 7 · Export your bookExport one page or all of them as PNG, a print-ready PDF, a CBZ for comic readers, or a viewer that opens in any browser. 300 or 600 DPI, your choice.

From an empty page to a lettered one.

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.

01THE PAGESix formats, one to nine panels

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.

02LAYOUT BUILDERNinety arrangements, in five steps

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.

03THE PANELSNothing is fixed once it is generated

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.

04THE PHOTOGRAPHSDrag them in from Explorer

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.

05THE NOISE154 sounds, drawn 688 ways

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.

06EXPORTOne page, or all of them at once

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.

07COVER STUDIOA sheet that gets cut, not a screenMeasured, not guessed
  • A cover is not an inside page with different art on it: it is a sheet the guillotine cuts, and everything in this tab exists because of that cut
  • Sixteen formats, each with its trim in inches and in millimetres — Silver and Golden Age, trade paperback, digest, magazine, the Franco-Belgian album and grand format, A4, square, tankōbon JIS B6, shinsho, manga in its American edition, and your own size in either unit
  • The modern American comic appears twice, on purpose: 6.625 × 10.25, the figure printers publish, and 6.625 × 10.1875, the one professionals use. Hover either and it tells you where the number came from and where the sources disagree
  • Guides drawn over the art, not under it: bleed shaded, the trim line in gold, the safe area dotted, the spine band, and the white box the barcode goes in
  • A plain cover, or a wrap-around — back, spine and front on one sheet — with the spine worked out from the page count and the paper: spine = pages / PPI, plus the boards on a hardback and whatever the binding adds
  • Fifteen papers with their published figures, and a PPI of your own for when your printer quotes a different one — on heavy coated stock two published tables disagree by a tenth of an inch
  • Ten texts already in place — title, issue number, month and year, price, publisher, credits, age warning, copyright, spine text, back-cover text — each landing where that piece of a cover usually sits, inside the safe area, and behaving as an ordinary text object afterwards
  • Two exports: the whole sheet with its bleed, for the printer, and the same sheet trimmed to final size, for showing on the internet. Both carry the resolution written into the file (the pHYs chunk), so a printer opens them at the right size rather than at 72 DPI
  • Every figure comes from docs/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 invented

Most of this exists because something small was annoying.

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.

01PRECISIONA minus and a plus on every number

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.

02UNSAVED WORKIt asks, and the question comes back

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.

03NATIVERust, and the graphics card

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.

04THE LIBRARYSized for the screen you actually have

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.

05THE WORKSPACEMove the sheet, not your head

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%.

06KEYBOARDThe shortcuts you would guess
  • Ctrl+S save over the project file · Ctrl+Shift+S save as
  • Ctrl+O open · Ctrl+N new comic
  • Ctrl+E export the page to PNG · Ctrl+Shift+E export the HTML viewer
  • Ctrl+Z undo · Ctrl+Shift+Z or Ctrl+Y redo
  • Ctrl+D duplicate the selected panel or effect
  • Delete remove the selected panel or effect

Three programs. One comic. Use one, two, or all three.

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.

01Comic PipelineFrom story to pictures

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.

02ComicBubbleLettering

586 hand-drawn balloons in 15 styles and a dozen comic fonts. Your dialogue lands on each panel, beside the right character.

03Panel ForgePages, sound and printYou are here

Automatic page layouts, 708 drawn sound effects in 10 packs, 299 graphic shapes and 56 title styles. Export PNG, PDF or CBZ.

Fourteen languages, no account.

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.
