How to Create Poster From PDF
Turning a single PDF page into a large-format poster involves splitting it across multiple standard-sized sheets that you print and assemble — a technique called tiling. This is how you create wall-sized charts, architectural plans, conference posters, and event banners using a regular office printer instead of a wide-format plotter. SublimePDF divides your page across Letter or A4 sheets with alignment marks for seamless assembly.

Upload your PDF
Open the Create Poster tool and upload the PDF containing the page you want to enlarge. If the PDF has multiple pages, select the specific page to posterize.
Set the target poster size
Choose the final assembled size — standard options include 24×36 inches, 36×48 inches, A1, A0, or custom dimensions. Alternatively, specify a scale factor (200%, 400%, etc.) relative to the original page.
Choose tile paper size
Select the paper size your printer uses — Letter (8.5×11) or A4 (210×297mm). The tool calculates how many sheets are needed. A 36×48 inch poster requires approximately 20 Letter-sized sheets.
Configure overlap and marks
Set the overlap between adjacent tiles (typically 0.5–1 inch) so you have room to align and glue sheets together. Enable crop marks to show where to trim, and assembly marks that indicate which tile goes where (row/column labels).
Preview the tile layout
View the tile grid showing how your poster is divided across sheets. Each tile is labeled (A1, A2, B1, B2...) and the preview shows what portion of the original image each sheet contains.
Download and print
Download the tiled PDF where each page is one printable tile. Print all pages at 100% scale without any printer scaling. Cut along trim marks, then assemble tiles from top-left to bottom-right, overlapping edges for alignment.
Pro Tips
- 💡 Use a 1-inch overlap for large posters and a 0.5-inch overlap for smaller ones. More overlap gives you more alignment margin but uses more paper.
- 💡 Print one tile first and hold it against the poster preview on screen to verify the scale is correct before printing all tiles.
- 💡 For clean assembly, use a paper trimmer (not scissors) to cut along the trim marks. Straight cuts make alignment much easier.
- 💡 Mount assembled posters on foam board or cardboard to prevent drooping and give the joined tiles rigidity.

How to Create PDF From Images
Whether you're compiling a photo album, turning whiteboard snapshots into meeting notes, or assembling product images for a catalog, creating a PDF from images gives you a single shareable file with consistent quality. Unlike sending a zip of images, a PDF displays in the correct order in any reader without requiring unzipping. SublimePDF supports batch image-to-PDF creation with layout and quality controls.
How to Create Booklet From PDF
A booklet rearranges PDF pages so that when printed double-sided on standard paper and folded in half, the pages fall in the correct reading order. This is called imposition — a process that transforms sequential page order (1, 2, 3, 4...) into the specific print sheet order needed for folding (e.g., 4, 1, 2, 3 on a single sheet). SublimePDF handles the imposition math, page rotation, and scaling automatically.
How to Create PDF From Markdown
Markdown is the lingua franca of developer documentation, README files, and technical writing — but sharing .md files with non-technical stakeholders rarely works. Converting Markdown to PDF preserves your formatting, code blocks, and tables in a universally readable document. SublimePDF's API accepts raw Markdown or a Markdown file and returns a styled PDF with syntax-highlighted code, proper heading hierarchy, and automatic table of contents.
