PDF proofing your clients can actually finish

Upload the PDF and send one link. Your client comments on the exact spot, or on the exact words, and approves the round when it’s right.

How it works

Three steps, one link

  1. 1Example
    PDF
    brochure-final.pdf
    Page 2 of 8
    2
    MR
    Marco, client
    Use the new phone number on page 2.

    Step 1: Upload the PDF

    Start a PDF project and upload the file. TweakTick turns every page into a strip your client can scroll. Then send the review link.

  2. 2Example
    clientsite.com

    3
    SK
    Sara, client
    Can the logo be a bit bigger here?

    Step 2: Your client marks it up

    They click a page to drop a numbered pin and type what to change. Your team replies on the pin, so each point stays in one thread.

    Step 3: Approve the final round

    Upload a new version as round 2, and the next. When it’s right, your client presses Approve and confirms with a 6-digit code from their email.

Every round ends with a clear yes

Approving works the same for a PDF as for a website: a 6-digit code sent to your client’s email confirms it was them.

Questions

Do my clients need an account to review a PDF?+

No. Your client opens the link you send, comments and approves. They never create an account or a password.

Can clients comment on specific words, not just a spot on the page?+

Yes. They press Select text, select the words and comment on them. The words stay highlighted with the comment’s number. Scanned pages have no text to select, so they get pins instead.

Can I send several PDFs in one round?+

Yes, up to 10 files, for example a brochure, a flyer and a price list. Your client reviews them with a file menu and approves them all at once.

How big can a PDF be?+

Up to 50 MB, and your plan may allow less. A bigger file is refused before it uploads, with the limit shown.

What does the approval cover?+

The original file and every page. The sign-off record stores a fingerprint (a SHA-256 hash) of each, with who approved, the exact sentence they agreed to and when.

Can I review Word or PowerPoint files too?+

Yes. TweakTick turns them into PDF pages you can pin, the same way.
