## Overview

BlockPoster.ai solves a very specific printing problem: most home printers only take A4 or Letter paper, yet many people want poster-sized wall art. The site takes one image, lets you choose paper size, orientation, grid width, margins and overlap, then splits the picture into numbered sheets that assemble into a single oversized print. Everything happens in a browser workspace with a live preview, so you can see the finished dimensions, page count and effective DPI before you commit to paper.

A distinctive design choice is that ordinary uploads are decoded, cropped and split on your own device rather than on the server, which makes the tool practical for family photos, classroom material and other personal images. The free edition exports a single-image multi-page PDF with a small brand watermark and a 150 DPI cap, while paid HD downloads remove the watermark, allow more sheets across and support batch export. AI artwork generation is a separate cloud feature that uses prompts and optional reference images.

The workspace also includes practical assembly aids: an overlap zone so neighbouring sheets repeat a sliver of image detail, page numbers, optional trim guides and a printable calibration ruler to verify your printer is not scaling output. The result is a tool aimed at hobbyist printers, teachers and parents who want large posters without a large-format printer.

## Pricing & Plans

Free plan covers single-image block poster PDFs at up to 150 DPI with a small brand watermark, no account required. Paid HD downloads remove the watermark, raise the sheet limit and add batch export. AI image generation uses credits. Exact prices are not published on a public pricing page.

## Key Features & Capabilities

- **Local image splitting:** Uploaded JPG, PNG or WebP files up to 40 MB are cropped and split inside the browser, so original photos are not sent to a server.
- **Five paper sizes:** A4, US Letter, A3, US Legal and Tabloid are supported in portrait or landscape, with adjustable margins to match your printer.
- **Live layout preview:** The preview, page grid and page-by-page sheet view recalculate instantly as you change size, crop, overlap or orientation, and show the effective DPI.
- **Assembly-ready PDFs:** Exports include an assembly guide page, page numbers, optional trim guides, crosshairs and an overlap band to align sheets accurately.
- **Built-in AI art generator:** Generate original poster artwork from a text prompt, optionally with a reference image, then feed the result straight into the splitter.

## Primary Use Cases

- **Family photo wall art (Parent):** Blow up a favourite holiday snapshot into a poster spanning several A4 sheets and assemble it with tape from the back.
- **Classroom displays (Teacher):** Create large maps, diagrams or class artwork on a school printer without needing a large-format machine.
- **Party and event backdrops (Event organiser):** Print a big banner-style image or signage piece from a single source picture and mount it sheet by sheet.
- **AI-generated wall decor (DIY decorator):** Generate an abstract or fantasy scene with the AI tool and print it as a statement piece of wall art.

## Strengths

- Free tier is genuinely usable, with no sign-in for basic multi-page PDF exports
- Photos stay on the device during normal uploads, which is good for private images
- Print-ready extras such as overlap, page numbers, trim guides and a calibration ruler
- Clear AI disclosure separating local processing from online generation

## Limitations

- Free output carries a brand watermark and is capped at 150 DPI
- No public pricing page, so HD and credit costs must be checked inside the app
- Large images and long PDFs depend on your device's memory
