Carousel Slide Generator — Tool
Safe UI & Anti-Phishing: The form uses only text inputs and textareas. Do not enter credentials or personal data. The tool is visually a utility, not a login form.
How it works
The generator extracts headings or short lines from the text you supply. If you paste HTML, it tries to identify <h1>–<h6> elements and other significant lines. If you paste plain text, it uses simple heuristics to split by paragraphs and sentences, looking for short, punchy lines suitable for a slide headline. The tool then lays each headline onto a square 1080×1080 canvas with an accessible, high-contrast dark background and white text. It generates the PNGs client-side and zips them for download. All rendering is done locally in your browser — nothing is uploaded to any server.
Frequently Asked Questions
Q1 — What exactly does the Carousel Slide Generator do?
A1 — This generator converts headings or short lines of text into polished Instagram-ready slides sized at 1080×1080 pixels. It accepts pasted text, pasted HTML, or a URL (subject to CORS), extracts meaningful lines (headlines, key bullet points, or summary lines), designs 6–10 slides with consistent typography, and produces PNG images. The images use white text on an accessible dark background to guarantee high contrast. The generated images are bundled into a ZIP file for easy download and use on Instagram or other social platforms. Keywords: carousel generator, Instagram slides, PNG export, white-on-dark slides.
Q2 — Who should use this tool?
A2 — Bloggers, content creators, social media managers, businesses, educators, and anyone who wants to convert an article, list, or transcript into a visual carousel for Instagram or similar platforms. It’s helpful for repurposing blog posts into shareable quick-swipe content, turning lists or tips into slides, and creating visually consistent content for brand channels. It’s especially useful for users who want fast, consistent slide output without design software.
Q3 — Does it work with any website URL?
A3 — You can attempt to fetch any public URL by entering it in the Fetch URL field and clicking "Fetch URL". However, many modern websites prevent cross-origin reads via CORS. If the browser blocks the request due to CORS, the tool will show an error and you can instead paste the page text or save the page HTML and paste it into the text area. The extraction logic works best when the HTML includes semantic headings (<h1>–<h6>) or clear paragraph tags. If a site blocks CORS, copying the article text and pasting it into the tool is a reliable workaround.
Q4 — How does the tool pick which lines become slide headlines?
A4 — The generator uses a priority approach: first it scans for semantic headings (h1–h6), then for list items, then for short paragraphs and sentence fragments. It ranks lines by length and punctuation (short lines of ~20–70 characters often make good headlines). It then fills the requested number of slides with the top-ranked lines. If there are more slides than lines, the tool will split longer paragraphs into shorter segments or duplicate a heading with supplementary subtext. You can also manually edit the extracted lines after generation by copying them and re-pasting to reorder or tweak before re-generating.
Q5 — Can I change the font size, text alignment, or the number of slides?
A5 — Yes. Use the "Slides to generate" dropdown to choose 6–10 slides, and adjust "Heading font size" or "Subtext font size" to control typography. The current version focuses on bold center-aligned headings suitable for Instagram. Future versions can add more alignment and theme presets. Font sizes are applied in pixels; increase them for larger text emphasis, or lower them for more breathing room if longer lines are used.
Q6 — Are the generated images safe for accessibility and SEO?
A6 — The generator uses high-contrast colors (white text on a dark background) and enforces readable font sizes to aid legibility and accessibility. For SEO, the tool lets you set ALT text and captions for the images before download; when you upload the PNGs to a platform or website, include the provided ALT text and captions to improve discoverability and accessibility. The tool itself does not upload images anywhere — everything is generated locally in your browser.
Q7 — How are images bundled and downloaded?
A7 — After generation, each slide is rendered to an off-screen canvas at 1080×1080 pixels. The code then converts each canvas to a PNG Blob and adds it to a ZIP file using JSZip. When zipping completes, the tool triggers a download using FileSaver.js. The default filename can be customized in the "ZIP filename" field. This approach avoids server-side processing and ensures the images remain on your device only.
Q8 — What about CORS and fetching external pages?
A8 — Browsers restrict cross-origin requests to prevent data leaks. If a website doesn’t permit cross-origin reads, the fetch attempt may fail. When that happens, copy the article content manually and paste it into the text area. The tool is designed to gracefully handle both fetched HTML and pasted text. If you control the source site, you can enable CORS or use a server-side proxy you trust (not recommended unless you trust the server), but the easiest method is manual paste.
Q9 — I need custom branding or a logo on each slide. Is that possible?
A9 — The current in-browser version focuses on core text layout and export. To add logos/branding, you can paste a small Data-URL image or use an upload extension. For now, a simple approach is to add branding in a post-processing step (e.g., use an editor to overlay a logo on the generated PNGs) or request an enhanced version of this tool that accepts an uploaded logo and draws it on each canvas before export. This is a planned enhancement for future updates.
Q10 — What are the recommended content types for best visual results?
A10 — Short, punchy lines work best: headlines, quotes, numbered tips, short list items, and short sentences (roughly 20–70 characters). Avoid pasting very long paragraphs as headlines — instead split long content into bullet points or edit for brevity. If you paste long-form content, use the slider or line editing to select the best lines for each slide. The generator includes heuristics to split and summarize text for you, but manual curation produces the best visual results.
Q11 — Is this suitable for commercial projects and client work?
A11 — Yes. Because the tool runs locally and outputs standard PNGs, you can use the slides in commercial projects, marketing posts, client social assets, and presentations. Make sure any source content you paste is licensed appropriately (you own the rights or have permission). The tool does not add watermarks and the images are yours to use.
Q12 — What if I want more styling options or other aspect ratios?
A12 — This release focuses on 1:1 Instagram slides sized at 1080×1080 with white-on-dark design for maximum contrast. If you want additional themes (light mode, brand colors), different aspect ratios (story 1080×1920, LinkedIn 1200×628), or advanced layout options (multi-column slides, images + text), these are feasible additions. Contact the tool author or modify the code to change canvas size and rendering behavior — all rendering is done via the canvas API and is straightforward to adapt.
Q13 — Can I preview each slide before downloading?
A13 — Yes. After you click "Generate Slides" the preview thumbnails appear. Clicking a thumbnail opens the full-size slide image in a new tab where you can inspect, right-click, and save individually. The ZIP option downloads all images at once.
Q14 — Is there a limit on how many slides or how much text I can paste?
A14 — The tool is optimized for 6–10 slides, as requested. You can paste longer text, but extraction time and browser memory use may increase with extremely large inputs. For best performance, keep pasted content to a few thousand words at most. If you need hundreds of images, consider a batch server-side script instead — but that would require trust in the server. This tool keeps everything local and manual batching is recommended for massive jobs.
Q15 — Where can I get support or request new features?
A15 — Typically, support or feature requests are handled via the blog contact or comment section. Mention specifics such as "branding/logo on each slide" or "story aspect ratio" so the feature can be prioritized. Because this is an in-browser tool, many enhancements are possible and relatively quick to implement.
