Editing

Adding Images, PDFs and SVGs
What you can put on the canvas, how each type gets there, and what happens to a multi-page PDF when you import it.
Moving, Resizing and Rotating
Selecting media, dragging it, pulling the handles, rotating freely or in 90-degree steps, and duplicating what you already placed.
Fitting an Image to the Canvas
Fit & Stretch, Fit & Keep Ratio, and Cover — three automatic resize modes that keep an image sized to the layout as you change it.
Layers and Stacking Order
Which piece of media sits in front of which, and how to change it — a layers panel in the browser and desktop apps, a drag-to-reorder list on Android and iOS.
Adding and Styling Text
Adding a text box, editing it directly on the canvas, and changing the font, size, style and color — including where the browser and mobile apps differ.
Guides, Rulers and Snapping
The canvas lines things up for you as you drag, shows where the sheet seams will fall, and lets you pull your own guides off the rulers.
Zooming and Panning the Canvas
How to get close enough to place something exactly, and back out to see the whole poster — with a zoom slider on the browser and desktop apps and pinch on mobile.
Enhance an Image with AI
An offline AI upscaler that adds detail to an image before you print it big. It runs on your device, nothing is uploaded, and you can always revert to the original.
Undo and Redo
Stepping back through your edits, what counts as a single step, how far back the history goes, and why it does not survive closing the app.

Printing & Export

Margins
The blank band around each tile. It is what keeps your printer from cutting content off, what the cut guides are drawn in, and what overlap is measured against.
Cut Lines and Scissor Marks
The two printed guides that tell you where to cut each sheet: five cut line styles including corner-only crop marks, and a scissor icon in the margin.
Page Numbers on Tiles
Printing a label on every sheet so you can tell which one goes where. Column and row, or a single running number.
Overlap on Tiled Prints
A strip of the neighbouring tile printed into the margin band, so a slightly short cut lands on duplicated image instead of bare paper. It is measured as a fraction of your margin, not as a length.
Export Resolution (DPI)
Standard, High and Max control how many dots per inch the export renders at. Higher is sharper and larger; the difference only helps if the source image can supply the detail.
Export Formats: PDF, Vector PDF and Images
Three ways to get your tiled poster out of the app, what each is good for, and why a vector PDF is the right answer for text and line art.
Where Your Export Goes
The export ends in a success dialog, and where the file lands from there depends on the platform. Images and PDFs are handled differently on phones.
Print Settings That Matter
Docuslice produces the file; your printer dialog decides what lands on paper. Five settings there can ruin a correct export, and scaling is the one that does it most often.
Assembling Your Poster
Sorting the sheets, cutting on the right edges, laying them in the correct order and taping the back. The physical half of tiled printing, in order.

Troubleshooting

Why Some of My Printed Pages Are Cropped — and How to Fix It
Content sliced off near a sheet edge comes from the margin being inside the printer's unprintable border, or from the print dialog filling, resizing or bordering the page. Raise the margin to 0.50 in ...
How to Get Rid of White Gaps When Taping Tiled Prints Together
Thin white lines along the seams are a cutting problem, not a printing one. Overlap prints a strip of the neighbouring tile so a short cut lands on image instead of bare paper.
Why My Print Is Blurry or Pixelated — and How to Fix It
Almost always the source image rather than a setting. Check the resolution you started with, then export resolution, then AI enhancement — in that order.
My Poster Printed at the Wrong Size
Nearly always the print dialog scaling rather than the app. Check for Fit to Page first, then confirm you were in size mode with the right paper.
My Poster Needs More Sheets Than I Expected
The sheet count is worked out against the usable area of each sheet, not the whole sheet, and it always rounds up. Both facts add sheets, and both are adjustable.
My Export Failed or Was Blocked
Two causes: a permission the app was refused, or a device running out of memory on a large poster. Both are recoverable.
My Exported PDF Is Enormous
File size is driven by the export resolution and the sheet count, and by whether the export is raster or vector. Three changes bring it down.
My PDF Did Not Import Properly
Blank pages, missing pages, or a file that will not open at all. What Docuslice does with a PDF, and what to do when a file does not cooperate.
The Colors Look Different on Paper
Screens emit light and paper reflects it, so a perfect match is not achievable. Here is how close you can get, and what actually moves the needle.
I Paid but Pro Did Not Unlock
The payment cleared and the features did not arrive. Do not pay again — here is the order of things to try, and what happens behind the scenes.
