Best Online PDF Annotation Tools

PDF tools differ in whether they edit document text, add native highlights or simply provide a visual review layer.

A practical method

Choose based on the job. For redlining contracts or searchable highlights, use a document-focused editor. For storyboards or layout critique, import pages into Framink and draw directly on the visual region.

What to check

Framink converts pages to review frames rather than rewriting the PDF file.

Next step

Try this with your own file in the Framink studio. For more context, read the related guide.
