BMP Export | Quintaphon Docs

BMP Export scans the active webpage for BMP images in markup, responsive srcset, and CSS backgrounds, then opens a dashboard where you can preview, select, rename, and resize assets before downloading. Export natively as BMP or convert to JPG; batch selections into a ZIP archive. All processing runs locally in your browser.

TIP

Use BMP Export on pages that already serve BMP in their HTML source, not only formats the browser displays as fallbacks.

Getting started

Install BMP Export from the Chrome Web Store and pin it for quick access.
Open a page that serves BMP images in its source or stylesheets.
Click the toolbar icon to scan the tab. A dashboard tab opens with detected images.
Select images, adjust settings if needed, then download individually or as a ZIP.

INFO

Restricted pages such as chrome:// URLs and the Chrome Web Store cannot be scanned.

Scanning & preview

The extension inspects <img> and <source> tags, srcset attributes, and computed background-image values for BMP URLs. Lazy-loaded and responsive sources are included when present in the DOM at scan time.

Each result appears as a card with a checkerboard preview (useful for transparency). Use Select All to toggle the full set, then open per-image settings for fine control.

Export options

Choose BMP or JPG as the default batch format from the sidebar. Per-image settings let you rename files, resize with aspect ratio locked, and download a single asset in either format.

JPEG exports add a white background when converting from canvas.

WARNING

Respect copyright and site terms when downloading images. Use exported assets only where you have permission.

Features

Deep page scan: Finds BMP in img/source tags, srcset, and CSS backgrounds.
Visual dashboard: Review detected images in a selectable grid with dark/light theme.
Resize & rename: Adjust dimensions with locked aspect ratio before exporting.
Batch ZIP: Download many images in one dated archive.
BMP or JPG: Switch batch output between native BMP and JPG conversion.
Local processing: Fetching and canvas encoding stay in your browser; nothing is uploaded.

Privacy

BMP Export reads image URLs from the page you scan and fetches them through the extension background worker for local processing. Scanned URLs and theme preferences may be stored briefly in chrome.storage.local to pass results to the dashboard tab. Quintaphon does not receive your browsing data or downloaded files.

See the Apps & Extensions Policy and Privacy Policy for company-wide details.

Need help?

If no images appear, confirm the page actually references .bmp URLs in its markup. Refresh and scan again. Cross-origin restrictions may block canvas conversion for some hosts while direct download still works.
