Bindery writes standard PDF annotation objects — Text (sticky note) comments with popups, Highlight, Square and FreeText marks with proper appearance streams, and Link annotations to a web address or another page of the same file. Open the result in Acrobat, Preview, Chrome or Edge and the comments are there to read, edit, reply to or delete.
Existing links on a page are listed too, so you can strip a dead URL or a tracking link before sending. Prefer permanent marks? Turn “editable annotations” off and Markup draws them into the page instead. Bindery runs entirely in your browser — your file is never uploaded, so there is nothing to delete from a server afterwards.
How it works
- Drop the PDF and open Comment & link
- Pin notes, drag highlights and boxes, draw a box and enter a URL or page number
- Apply — the annotations are written locally and the file downloads
Comments the recipient can work with
Bindery writes standard PDF annotation objects: sticky-note comments with popups, highlights, boxes and free-text labels with proper appearance streams, and link annotations to a web address or to another page of the same file. Open the result in Acrobat, Preview, Chrome or Edge and the comments are there to read, reply to, edit or delete — the review workflow every PDF reader supports. Existing links on a page are listed too, so a dead URL or a tracking link can be stripped before the file goes out.
- Reviewing a contract or a design proof with a colleague.
- Adding a table of contents’ worth of internal links to a long document.
- Replacing a broken link in a PDF you did not author.
Editable annotations or permanent marks
Annotations are objects on top of the page; they can be changed by anyone with a full reader, which is the point for review and the wrong thing for a final copy. When marks must be permanent, turn “editable annotations” off and Markup draws them into the page — or flatten an annotated file when the review is over, which bakes the comments in or removes them.
Annotating in the browser versus uploading
| Comment & link | Bindery | Upload-based tools |
|---|---|---|
| Where the file is processed | In your browser tab, on your device | Uploaded to the service’s servers |
| Output | Standard annotations with appearance streams | Similar; some tools rasterise |
| Links | Add URL and internal page links; list and remove existing ones | Varies |
| Confidential drafts | Never leave the device | Uploaded, retained for a period |
| What exists afterwards | The original and the new file, both on your device | A server copy until the retention window ends |
| Works offline | Yes, once the app has loaded | No |
Questions people ask
Can the recipient edit or delete my comments?
Yes — that is the point of real annotations. They are standard objects with author, date and contents, editable in any full PDF reader. Use Markup’s flattened mode when marks must be permanent.
Do highlights show in every viewer?
Yes. Each annotation carries its own appearance stream (a multiply-blended fill for highlights), so viewers that do not synthesise appearances still display it.
Can I link to another page instead of a URL?
Yes. Type a page number instead of a URL and Bindery writes an internal destination that jumps to that page.
Will my comments show on a phone?
Yes. Each annotation carries its own appearance stream, so viewers that do not synthesise appearances still display it.
Can I link to a specific page?
Yes. Type a page number instead of a URL and Bindery writes an internal destination that jumps there.
Can I remove all comments at once?
Use Flatten with annotation removal to strip every annotation, or flatten without removal to bake their appearance into the page.
