What it does
colors
Yellow, green, pink, blue and purple. Give each one a meaning: facts, sources, questions, ideas.
Back on every visit
Each passage is found again from its text and the words around it, also when the site loads its text a moment later.
One library
Search across highlighted text, titles and addresses. Group by day, by site, or see one list.
Change or delete
Click a highlight on the page to pick another color or delete it. Select over an existing one and you edit it, with no double marks.
changes to the site
Marks are painted over the text by the browser, so the page's own code and layout are left alone.
permission
Storage, to keep your highlights. What you read and what you mark never leaves your browser.
Why highlights vanish when you reload a page
A browser forgets your selection the moment you click elsewhere. Chrome can make a link that highlights a passage (Copy link to highlight), but the mark appears only when someone opens that exact link, and it is never saved on your side.
Page Highlighter keeps each passage with the words around it, so it can find it again whenever you open the page, from a bookmark, your history or a search. If a site rewrites a passage so it no longer exists, the highlight stays in your library instead of on the page.
Your highlights stay with you
On your device
Everything is kept in your browser's local extension storage. No account, no cloud, no sync service.
Nothing leaves the browser
No analytics and no ads. The extension reads a page only to find your highlighted passages in it.
One permission
Storage, so your highlights are saved. It runs on the pages you read so you can mark them.

Questions
How do I highlight text on a web page in Chrome?
Add Page Highlighter to Chrome, select the text and click one of the five colors in the small toolbar that appears. The highlight is saved right away.
Do my highlights stay after I close the page?
Yes. They are saved per address, and the next time you open it they are painted back in place. If the site changes that passage, the highlight stays in your library.
Where can I see all my highlights?
Click the extension icon. A tab opens with every highlight you saved: search them, group them by day or by site, and follow the link back to the page.
How do I change a highlight's color or remove it?
Click the highlight on the page and the toolbar opens: pick another color or delete it. You can also delete highlights in the library.
Do my highlights sync between computers?
No. They are stored in this browser on this device. There is no account and no sync, which also means nobody else sees them.
Can I highlight text in a PDF?
No. It works on regular web pages, not on PDFs or Chrome's own pages.
