Split Long Text into Manageable, Equal-Sized Parts
Long text constantly collides with hard limits: 280 characters for a post, 160 for an SMS segment, a few thousand for a form field or an AI prompt, fixed batch sizes for translation and processing pipelines. Cutting a document into compliant pieces by hand means counting characters and juggling clipboard fragments. This free splitter divides any text into chunks of an exact size — measured in characters, words, or lines — or cuts it at a custom delimiter you already have in the text. Character and word modes keep words whole, each part is labeled and separated clearly in the output, and the whole process runs privately in your browser.
Splitting by Character Count
Character mode produces chunks no longer than the size you set, breaking at word boundaries so no word is cut in half. The default of 280 matches the classic post limit, and common alternatives include 160 for single SMS segments, 500 for comment fields, and a few thousand for prompt windows. Because breaks happen at spaces, chunks may come in slightly under the limit — that is intentional, keeping every part readable and paste-ready without mid-word hyphenation artifacts.
Splitting by Words or Lines
Word mode counts words instead of characters, which suits editorial workflows: divide an article into 100-word blocks for review, or prepare uniform passages for reading and translation practice. Line mode groups a fixed number of lines per chunk, the natural choice for line-oriented data — splitting a long log, a CSV without headers, or a list of records into batches of, say, 50 lines for import tools that choke on large files. In both modes the final chunk simply holds the remainder.
Splitting at a Custom Delimiter
When the text already contains natural cut points — scene markers like ***, section dividers like ---, or any string you have inserted — delimiter mode cuts exactly there, ignoring size entirely. Each segment between delimiters becomes one part, and the delimiter itself is removed. This is the cleanest way to explode a document you have pre-marked into separate pieces for individual editing, sending, or storage.
How the Output Is Organized
Each chunk is preceded by a labeled divider — Part 1, Part 2, and so on — with a blank line between parts, so the boundaries are unmistakable when you scroll the result. The labels make it easy to keep thread posts in order or to track which batch you have already processed. The output statistics report the number of parts produced and the size of the largest one, an instant check that every chunk respects the limit you were targeting before you start copying.
Threads, Messages, and Processing Pipelines
Writers turn essays into post threads by splitting at 270–275 characters, leaving room for numbering like 1/7. Support teams fit long updates into SMS segments. Anyone working with AI tools splits oversized source material into prompt-sized batches and feeds them sequentially. Localization teams cut documents into uniform blocks for distribution among translators. Data engineers break large line-based files into import-sized batches. The common thread is a hard limit downstream — the splitter guarantees each piece fits before you send it.
Privacy and Client-Side Processing
Splitting runs entirely in your browser with JavaScript; the text never leaves your device, is never uploaded, and is cleared from memory when you close the page. Long confidential documents — contracts, manuscripts, internal reports — are safe to split here. There is no practical length restriction beyond browser memory, and the download button saves multi-part output to a single text file when the clipboard is unwieldy.
