Quick answer

Long Article Slicer turns long text into multiple PNG cards for social publishing.

It runs locally and is useful for carousels, story posts, quote threads, and repurposed blog content.

Best inputs

Paragraph-based articles

Clear paragraph breaks help the slicer keep ideas together.

Social-ready drafts

Use concise sections when you want fewer, cleaner cards.

Bilingual copy

Chinese and English text can be split and rendered on the same card set.

Article slicing method
The tool groups text into cards by paragraph and approximate character length.
Paragraphs are preserved when they fit the selected limit.
Long paragraphs are split by sentence before falling back to length chunks.
Each slice is rendered locally to canvas and exported as PNG.
Example, Assumption, and Limitation
Use the result as a practical estimate or transformation, then confirm edge cases for critical work.

Example

Paste a 1,500-character article, set 420 characters per card, and export a ZIP of portrait PNG cards.

Assumption

The source text is plain article copy with paragraph breaks, not a complex layout.

Limitation

Automatic slicing cannot always match editorial emphasis; review each card before posting.

Common mistakes to avoid
These checks help prevent bad outputs, failed exports, and confusing results.

Using too many characters per card

Dense cards are harder to read on mobile. Lower the character limit for social feeds.

Skipping manual review

Automatic splits are fast, but you should still check context and line breaks before publishing.

Expecting platform-specific typography

The output is a clean generic PNG card, not an exact clone of any social platform UI.

Common use cases
These pages are built for lightweight browser-side work, examples, and planning.

Carousel posts

Repurpose a long article into a sequence of readable cards.

Newsletter snippets

Turn a newsletter idea into preview cards.

Thread planning

Break a long explanation into manageable sections.

Chinese social posts

Prepare long-form copy as mobile-friendly card images.

Frequently asked questions

Does the long article slicer upload my text?

No. Splitting, card rendering, PNG export, and ZIP generation all run in the browser.

How does it decide where to split the article?

It keeps paragraphs together when possible, then falls back to sentence-sized chunks when a paragraph is too long.

Can I export all cards at once?

Yes. The tool can download individual PNG cards or package all generated cards into a ZIP file.

Which social formats are supported?

It includes square, portrait, story, and wide presets for common social and publishing use cases.
