How to change GoFullPage screenshot quality and file size
Choose GoFullPage’s image format and PDF layout in its Options page. Learn what those settings change, how to compare file sizes, and what to try when exports are too large.
To change GoFullPage’s screenshot output, open the extension’s Options page and choose an image format or PDF size. Then capture the page and use Download image or Download PDF on the result page. GoFullPage documents PNG, JPEG, and PDF exports, with export choices configurable in extension options. The available documentation does not establish a numeric image-quality slider or a guaranteed file-size reduction.
Change the export format or PDF layout
- Open the GoFullPage extension in Chrome and go to its Options page. The extension’s getting-started guide describes configuring image format, PDF size, and the save-as dialog there. UI labels or placement may have changed since that guide was published.
- Choose the image format or PDF size for the kind of output you need.
- Capture the webpage with GoFullPage.
- On the result page, select Download image or Download PDF.
GoFullPage captures a page by scrolling through its visible sections. Its Chrome Web Store listing documents PNG, JPEG, and PDF exports. See the GoFullPage Chrome Web Store listing and the GoFullPage getting-started article for the product’s documented options.
Choose PNG or JPEG for an image
Choose based on the image and how you will use it:
| Format | When it may fit | What to check |
|---|---|---|
| PNG | When preserving lossless image data matters. | Check the actual file size for your capture. |
| JPEG | When a compressed image is suitable for your destination. | Compare its appearance and byte size with a PNG of the same page. |
The sources document both formats but do not provide a quality control, compression level, or expected percentage savings. A page with large photos may behave differently from a page made mostly of text and flat colors, so compare exports of the same capture rather than assuming one format will always be smaller.
Save a single-page PDF
If you want one continuous PDF page, set PDF Size to full image in the extension’s options, then capture and download the PDF. GoFullPage’s FAQ identifies “full image” as the single-page PDF setting. This controls page layout; the documentation does not say that it compresses the image or reduces the PDF’s byte size. Use standard paper-sized pages when the document needs conventional print pages.
Source: GoFullPage FAQ. The FAQ detail is based on the available search-result statement; the direct page content was not available for inspection.
Reduce file size without guessing
- Capture the page once and export it as PNG and JPEG.
- Compare both files’ byte sizes and inspect the details that matter in your image, such as small text and edges.
- Use the smaller format only if its appearance is acceptable for your destination.
- For a PDF, choose the page layout for reading or printing needs. Do not treat “full image” as a compression setting.
Very large pages can also run into browser image-storage limits. GoFullPage’s listing says such captures may be split into images in separate tabs because Chrome may not store them as one image. If that happens, the issue may be capture size rather than the selected format.
Troubleshooting
| Symptom | Likely reason | What to try |
|---|---|---|
| You cannot find an image-quality slider. | The available GoFullPage sources document format selection, not a numeric quality control. | Choose the documented format and compare the resulting files. Do not assume a slider exists. |
| The JPEG is not much smaller than the PNG. | File-size differences depend on the specific page content; no guaranteed savings are documented. | Check both exports from the same capture and use the one that meets your size and visual requirements. |
| The PDF has many pages instead of one. | The PDF size may be set to a standard paper layout. | Set PDF Size to “full image” for a continuous single-page PDF. |
| The PDF is still large after choosing “full image.” | “Full image” changes page layout, not a documented compression level. | Choose the layout you need and check the resulting file. The cited sources do not specify a PDF compression control. |
| A very long capture is split into multiple images. | The browser may not be able to store the complete page as one image. | Use the separate output images described by the extension listing, or capture a smaller region if one file is required. |
| Options or download controls look different. | The getting-started guide dates from 2020, and extension interfaces can change. | Check the current extension Options page and result page; the documented workflow is to configure before capture and download from the result. |
Or skip the browser setup
If your goal is to get a screenshot file from a URL, ScreenshotNeo provides a website screenshot API and MCP server. Its API can return PNG, JPEG, WebP, or PDF; the GoFullPage settings described above apply to the GoFullPage extension.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpSee the ScreenshotNeo API documentation for the request options. Before a capture, ScreenshotNeo accepts cookie or consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets; each step can be turned off. Bot checks, blank pages, and failed loads are never billed, and responses identify the page verdict and billing status. Its MCP server lets AI agents use the take_screenshot, get_page_info, and capture_pdf tools. The free plan includes 1,000 screenshots per month with no card; paid plans start at $5 for 3,000 screenshots.
Sign up for 1,000 free screenshots a month, with no card required.
Performance, reliability, and cost
For GoFullPage, output size and capture reliability depend on the page and the browser’s ability to hold the captured image. Its listing specifically notes that very large captures may be divided across tabs. The cited sources provide no quality benchmarks, file-size savings, or export-cost figures, so measure the actual files for your page and workflow.
ScreenshotNeo charges only for clean shots: bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits cost nothing. Its plans are Free (1,000 shots/month), Starter ($5 for 3,000), Growth ($15 for 15,000), Pro ($39 for 60,000), Scale ($99 for 250,000), and Business ($249 for 1,000,000); yearly billing gives two months free, and every feature is on every plan.
FAQ
Does GoFullPage let me enter a specific JPEG quality percentage?
The researched official sources do not document a numeric quality setting. They document choosing an export format.
Does “full image” make my PDF smaller?
It makes the PDF a single continuous page. The available FAQ detail does not describe it as compression.
Which format should I send to someone?
Use the format their workflow accepts, then compare the actual size and appearance of your own capture. The sources do not claim one format is always best.
Can I automate screenshots instead of using the extension?
Yes. ScreenshotNeo accepts a URL in a single API request and also offers an MCP server for AI agents. See its documentation for available formats and options.
