Why you should use BugHerd to annotate PDF files

The best PDF annotation apps offer more than just basic annotation of PDF files.
PDF annotation tools such as BugHerd also offer your team and clients a way to track all feedback for easy management.

BugHerd is different to the free PDF annotation apps on the market because users can edit PDFs, photos, designs and drawings, by simply pointing and clicking right on the element that they want to add notes to. All feedback then flows into an integrated task board to ensure easy tracking and management.

BugHerd's user friendly interface speeds up the annotation process

Quickly mark up PDF documents with BugHerd's simple point and click functionality and provide feedback by leaving virtual 'sticky-notes' on your PDF file.

With BugHerd users can annotate using text comments, drawing tools, virtual handwritten annotations, screen recordings, or attaching files such as screenshots, images, or documents.

Designers, web dev teams and project managers benefit from visual and contextual feedback and being able to look at comments through the reviewer's lens. When feedback is shared using BugHerd it's as accurate and contextual as possible, enabling you and your team to collaborate and resolve issues easily and efficiently.

With BugHerd, users are able to annotate PDFs and other documents, but the software also offers collaboration features such as task assignment, comment threads, and issue tracking.  If you're working with a team on a project and need to collaborate on annotations and feedback, BugHerd's advanced team-oriented features will fast track your design projects.
