For a single long image on desktop, Firefox is the clearest built-in option: open the page, choose Take Screenshot, select Save full page, then Download the PNG. On iPhone, Firefox’s documented full-page workflow saves a PDF instead. In Chrome, a Web Store extension can scroll and stitch the page before exporting PNG or JPEG.

The quickest method: Firefox on Windows, Linux or macOS

Mozilla documents full-page screenshots in Firefox, including a saved PNG or a clipboard copy. You can start from the context menu or a keyboard shortcut.

  1. Open the webpage and wait for the content you want to preserve.
  2. Right-click an empty area of the page and choose Take Screenshot. You can also press Ctrl+Shift+S on Windows or Linux, or Command+Shift+S on macOS.
  3. In the screenshot toolbar, choose Save full page. This tells Firefox to capture the page beyond the currently visible viewport.
  4. Select Download to save the image file. Mozilla identifies the downloaded screenshot as a PNG.
  5. Choose Copy instead if you need to paste the full capture into an editor, document or message without first saving a file.

Firefox also offers a visible-area capture. Use that option when you need only what is currently on screen rather than one tall image. The full-page command is the one to use for an article, documentation page or receipt that extends below the fold.

Mozilla’s instructions are documented in Take screenshots in Firefox. Browser controls can change between versions, so the label may move even though the workflow remains the same.

Chrome: use a scroll-and-stitch extension for PNG or JPEG

The evidence available for Chrome is extension-based rather than a documented built-in workflow. A Chrome Web Store listing for FullPage Capture – Full Page Screenshot describes an extension that scrolls through a webpage, captures sections and stitches them into one long result. Its listing describes PNG and JPEG downloads, along with PDF export.

  1. Open the extension’s Chrome Web Store listing and review its current permissions, privacy information and publisher notes.
  2. Install it only if those permissions fit the pages you plan to capture.
  3. Load the target page in a normal tab and wait for visible content, images and any expandable sections you need.
  4. Activate the extension from Chrome’s toolbar. Follow its capture control to start a full-page scroll-and-stitch operation.
  5. Choose PNG or JPEG when you need an image, or PDF when a document is more useful, then save the generated file.

The store page is a publisher-provided feature description, not proof that every page structure will render perfectly. Pages with bot checks, unusual scrolling containers, continuously changing content or browser restrictions may produce an incomplete result. Another listing, GoFullPage – Full Page Screen Capture, is also available in the Chrome Web Store; check its current listing and permissions before installing it.

iPhone: the documented full-page result is a PDF

Mozilla’s Firefox for iOS workflow creates a full-page document rather than a tall PNG or JPEG.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  1. Open the page in Firefox for iOS.
  2. Take a normal iPhone screenshot.
  3. Tap the screenshot thumbnail that appears.
  4. Choose Full Page at the top of the screenshot editor.
  5. Tap Done, then choose Save as PDF.

This is appropriate when you need a complete record for reading, printing or sharing and PDF is acceptable. The documented steps do not produce a single long image file. See Mozilla’s Save web pages as PDFs in Firefox for iOS guide for the current labels.

Choose the method by device and output

Device or browser Documented route Output Best fit
Firefox desktop Take Screenshot → Save full page PNG download or clipboard copy A single long image with no extension
Chrome desktop Scroll-and-stitch Web Store extension PNG, JPEG or PDF according to the listing Chrome users who specifically need an image export
Firefox for iPhone Screenshot thumbnail → Full Page → Save as PDF PDF A complete page record when an image is not required

Exact built-in Chrome, Safari and Android instructions are not established by the documentation used here, so do not assume that a menu or shortcut from another browser exists on those platforms.

Make a long capture more reliable

Wait for the page’s real content

Capture after the headline, body, images and expandable sections you care about have loaded. A page that is still fetching content can result in blank areas or missing images regardless of the capture tool.

Watch for lazy loading and changing layouts

Scroll-and-stitch tools capture a page in sections. Lazy images may load only when their region enters the viewport, while advertisements, carousels or live counters can change between sections. If the result shows gaps or repeated elements, first let the page settle, disable optional moving content where the site allows it, and capture again.

Free tools Windows power users keep installed

One-click scans. No signup required.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Check nested scrolling areas

“Full page” normally means the document’s main scroll. A chat transcript, code pane or table inside its own scroll box may not be included in the same way. Capture that element separately if the tool offers an element-specific command, or use the element’s own export function.

Review extension permissions

A browser extension can potentially read page content. Before installing, inspect the current Chrome Web Store permissions and privacy disclosures, especially if you handle private dashboards, customer data or logged-in accounts.

Expect raster-image limitations

A PNG, JPEG or WebP is a picture, not a live webpage. Text will not remain selectable as HTML, links will not remain clickable, and very tall images can be awkward to open or share. Choose PDF when pagination, text selection or printing matters more than a single image.

Or skip the browser setup

ScreenshotNeo is a website screenshot API and MCP server. One GET request returns a PNG, JPEG, WebP or PDF for a URL, so you can create long captures from a script, CI job or AI workflow instead of operating a browser manually. Its full documentation is at screenshotneo.com/docs/.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

One-call examples

cURL

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webp

Python

import requests
r = requests.get("https://api.screenshotneo.com/v1/shot", params={"access_key": "YOUR_API_KEY", "url": "https://stripe.com"}, timeout=90)
open("shot.webp", "wb").write(r.content)

Node.js

const q = new URLSearchParams({ access_key: 'YOUR_API_KEY', url: 'https://stripe.com' });
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);

Replace the example URL with the page you need and choose the output and capture parameters described in the documentation. ScreenshotNeo can load a full page with lazy images, capture one element by CSS selector, use dark mode, select a device preset or custom viewport, apply retina scale, and return a PDF with paper size, margins, landscape orientation or page ranges.

Controls for difficult pages

  • Run custom CSS or JavaScript, click an element before capture, hide selectors, or wait for a selector, a delay or network idle.
  • Block ads, trackers, requests or resource types to make a cleaner and more predictable capture.
  • Send custom headers, cookies, a user agent or an Authorization header for pages that require a session or API access.
  • Set timezone and geolocation, use a transparent background, resize the image, or cache a result with a TTL you choose.
  • Create signed links for public <img> tags, submit asynchronous jobs with signed webhooks, or capture up to 100 URLs in one bulk call.
  • Use the usage API and OpenAPI specification for monitoring and integration. Parameter names used by other screenshot APIs also work, which can simplify migration.

Why the billing result matters

ScreenshotNeo removes cookie and consent banners, newsletter popups and chat widgets before capture; each step can be turned off. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads and cache hits are not billed. Every response identifies the page result and billing status with X-Page-Verdict and X-Billed headers.

The MCP server exposes take_screenshot, get_page_info and capture_pdf tools to Claude, Cursor and other MCP clients. Plans are:

Plan Included shots Price
Free 1,000 per month $0, no card

Troubleshooting

The Firefox “Take Screenshot” command is missing

Confirm that you are using desktop Firefox and right-click an empty page area rather than a browser toolbar or embedded frame. Try the documented shortcut: Ctrl+Shift+S on Windows/Linux or Command+Shift+S on macOS. If the interface still differs, consult Mozilla’s current support page because browser labels can change.

The saved image stops before the bottom

Make sure Save full page, not a visible-area selection, is active. If the page uses an internal scroll panel, that panel may need a separate capture. For an extension, retry after the page finishes loading and check whether the listing documents limitations for that layout.

Images or sections are blank

Wait for lazy content to load and capture again. A login wall, bot check, timeout or blocked request can prevent the browser from receiving the content. ScreenshotNeo reports these outcomes in its response headers and does not bill failed loads, blank pages, timeouts or bot checks.

The Chrome extension will not run

Check that it is enabled, that Chrome allows it on the current site, and that its permissions cover the page. Review the extension’s current store listing for restrictions. Do not grant permissions you cannot accept; use Firefox’s built-in capture or an API instead.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The output is too large to share

Use JPEG when a smaller photographic image is acceptable, resize the result, or choose PDF for a paginated document. If only one section matters, capture an element by selector with ScreenshotNeo rather than the entire document.

FAQ

Can a long PNG keep selectable text?

No. PNG, JPEG and WebP are raster images. Keep the original page or export PDF when text selection and search are important.
