To annotate a PDF, open it in the editor above and use Highlight to mark passages, Add text for margin notes, and Draw to circle or underline freehand. Nothing is uploaded — the file is annotated in your browser, and the marks are flattened into the download so they appear in Adobe Reader, Preview and phone apps. Three documents a day are free, with no sign-up and no watermark.
Drop it into the box above — it opens instantly, nothing is uploaded.
Use “Highlight” to mark passages, “Add text” for margin notes, and “Draw” to circle or underline freehand. Drag any annotation to reposition it.
Click Download — your annotations are baked into the file so they show up in every PDF reader.
Highlight clauses and drop margin notes before the next negotiation round.
Comment and highlight submissions without printing a single page.
Mark up lecture slides and papers the way you would with a highlighter.
Circle issues and note changes directly on the PDF proof.
DoceasePDF annotates your PDF entirely in your browser. Contracts under review, papers you're grading and study notes never touch a server — annotation happens on your device from start to finish.
Highlights, text notes and freehand drawing cover the marks most people need for review and study. Annotations are flattened into the downloaded file, so they display identically in Adobe Reader, Preview, browsers and phones.
Need more than markup? The same editor lets you white out text, sign, rotate pages, and merge or split documents before you download.
Continue your PDF workflow: Draw on PDF — Freehand circles, arrows and sketches., Add Text to PDF — Type notes and fill in blanks. or White Out PDF — Cover mistakes with a clean white box.
Students highlight readings and scribble margin notes; lawyers and managers flag clauses and leave comments for the next round; designers circle what needs to change on a proof. One annotator covers all of it — highlight, text notes and freehand drawing on any PDF, with every annotation movable and deletable until you download.
Some annotation apps store marks in a proprietary layer that vanishes when the file is opened elsewhere. DoceasePDF flattens annotations into the page content on download, so your highlights and notes look identical in Adobe Reader, macOS Preview, browsers and phone apps — no special software needed on the other end.

Yes — before downloading, click any annotation to select it, drag to move, use the corner handle to resize, or hit the X to delete it.
No. Annotation happens in your browser — your file never leaves your device, which makes DoceasePDF safer than upload-based annotators.
Yes. The annotator runs in any mobile browser — tap to place highlights and notes, and draw with your finger or a stylus.
Click Highlight, then drag across the passage you want marked. The highlight is a translucent block placed over the page, so it also works on scanned PDFs — where text-selection highlighters in other readers fail because there is no text layer to select.
Not with normal tools — annotations are flattened into the page itself on download, so they behave like printed content rather than a removable layer.
