What should I be looking for before uploading?

Substituted fonts, pages that differ in size from the rest, unexpected blank pages, images that look soft at full zoom, and anything that shifted at a chapter boundary.

Does viewing replace a printed proof?

No. A screen cannot show you paper colour, ink density, gutter loss at the binding or how a cover feels. For a book you care about, order the proof.

When is a viewer not the right tool?

When you need to change the file rather than inspect it. Annotation here is commentary layered over the page, so nothing you mark alters the underlying document, and a file that needs its pages or geometry edited has to go to a tool that rewrites it.

Free PDF Viewer and Annotator

The last look at an interior before it goes to Amazon is worth taking somewhere neutral. Your layout software shows you what you meant; a plain viewer shows you the file as it will be received.

That difference catches real problems. Fonts that were never embedded substitute here and look wrong. A page inserted at the wrong size stands out immediately when pages are shown in sequence. Blank pages that should not exist become visible when you can see the whole document as a reader would.

Annotation here is commentary, not editing. Notes and highlights record what needs changing; the change itself happens in the tool that produced the file.

Frequently Asked Questions

Can I edit the PDF here?

No. This is a viewer with annotation. You can mark up what needs changing, but the change itself has to happen in the software that produced the file.

Do my annotations change the file?

They are review notes on your copy, not edits to the document you upload. Treat them as a checklist rather than a correction.

Is my document uploaded to a server?

No. The file is opened locally in your browser, so it does not leave your device.
