Web Highlights makes\n  it easy to review and manage annotations without digging through old files or re-reading full documents.\n\u003C\u002Fp>\n\u003Cp>\n  You can bulk-edit tags, delete outdated notes, or merge duplicate highlights from your dashboard. This is great for\n  keeping your research tidy and your annotation process focused.\n\u003C\u002Fp>\n\u003Cp>\n  There’s also a handy email\n  \u003Ca href=\"https:\u002F\u002Fweb-highlights.com\u002Fblog\u002Fsay-goodbye-to-forgotten-articles-introducing-the-snooze-reminder\u002F\">\n    \u003Cu>“Snooze” reminder feature\u003C\u002Fu>\n  \u003C\u002Fa>\n  . You can set reminders to revisit specific PDFs or annotations later, which is perfect for long-term projects or\n  papers you must follow up on. Instead of forgetting about a useful PDF version you skimmed last week, Web Highlights\n  brings it back to your inbox at just the right time.\n\u003C\u002Fp>\n\u003Ch2 id=\"tips-for-efficient-pdf-annotation\">\u003Cstrong>Tips for Efficient PDF Annotation\u003C\u002Fstrong>\u003C\u002Fh2>\n\u003Cp>\n  If you're working with a lot of PDF documents, small habits can make a big difference in how effective your\n  annotations are.\n\u003C\u002Fp>\n\u003Cp>\n  One easy tip is to use color coding for priority. Mark important highlights in pink, possible references in yellow,\n  and general notes in blue. It is a simple way to visually separate what’s urgent from what’s just “good to know,”\n  making reviewing faster later.\n\u003C\u002Fp>\n\u003Cp>\n  Outside of PDFs, Web Highlights also includes a \n  \u003Ca href=\"https:\u002F\u002Fweb-highlights.com\u002Fdocs\u002Ffeatures\u002Freader-mode\">\u003Cu>Reader Mode\u003C\u002Fu>\u003C\u002Fa>\n   for regular web pages — it strips out ads, pop-ups, and clutter so you can focus on the actual content. You can\n  adjust font size, switch between light and dark themes, and tweak the layout. If you read a lot of articles alongside\n  your PDFs, it’s a nice complement to the PDF annotation workflow.

Does Web Highlights store the PDF itself or just the annotations?\u003C\u002Fstrong>\n\u003C\u002Fh3>\n\u003Cp>\n  Web Highlights does not store the PDF file itself. It only saves your PDF annotations, tags, and notes securely under\n  your account. This way, you can reopen the same file later and continue working using your preferred annotating tools.\n\u003C\u002Fp>\n\u003Ch3 id=\"2-can-i-annotate-password-protected-pdfs\">\u003Cstrong>2. Can I annotate password-protected PDFs?\u003C\u002Fstrong>\u003C\u002Fh3>\n\u003Cp>\n  Currently, most PDF annotation Chrome extensions, including Web Highlights, do not support annotation on\n  password-protected files due to browser-level restrictions. You’ll need to unlock the PDF first to use the annotation\n  features.\n\u003C\u002Fp>\n\u003Ch3 id=\"3-can-i-highlight-images-in-pdfs\">\u003Cstrong>3. Can I highlight images in PDFs?\u003C\u002Fstrong>\u003C\u002Fh3>\n\u003Cp>\n  Currently, you can’t highlight images inside PDFs — only selectable text. Image highlighting is available on regular\n  web pages, but PDF files are limited to text-based annotations. If your PDF contains charts or diagrams you want to\n  reference, you can add a text note next to a nearby highlight as a workaround.\n\u003C\u002Fp>\n\u003Ch3 id=\"4-how-do-i-share-an-annotated-pdf-with-colleagues\">\n  \u003Cstrong> 4. How do I share an annotated PDF with colleagues?\u003C\u002Fstrong>\n\u003C\u002Fh3>\n\u003Cp>\n  After you annotate your PDF in Chrome, you can export your highlights and notes to tools like Notion, Obsidian, or\n  Markdown and then share them. Alternatively, you can send your teammates the PDF link if it’s hosted online. They can\n  view annotations if they’re also using Web Highlights or receive your notes via export.\n\u003C\u002Fp>\n\u003Ch3 id=\"5-will-annotations-sync-between-chrome-and-edge\">\n  \u003Cstrong>5.
