Prepare a marked PDF copy that tells the recipient the page, original text, and exact replacement you want.
“Please change the deadline here” is not enough when a document contains three deadlines and the attachment exists in two versions. Mark the exact location and spell out the replacement. Then check the file you will actually send.
This workflow is for small-team owners and operations leads using a Mac and Preview. You need a PDF you are allowed to open and annotate. You will prepare a correction request so that the person with the source document can make the change and produce a new PDF version.
Prepare the right copy
Open the PDF and check its contents and version. Keep the original separately and make a copy for feedback. For example, create service-outline-v03-correction-01.pdf from service-outline-v03.pdf. This is a suggested naming convention, not a Preview feature.
Note the page, heading, and exact text you want changed. The page’s position in the viewer may differ from its printed number. If so, give both: “Fourth page of the file, printed page 2, Contact section.” The recipient should be able to find the same location without a phone call.
Mark the location and add an instruction in Preview
According to Apple’s PDF annotation guide, Preview can add shapes, text, and notes. These tools do not change the PDF’s existing text. The original sentence stays in the document; the annotation explains the correction you are requesting.
- Open your working PDF copy in Preview and go to the relevant page.
- Show the Markup toolbar if it is hidden. Controls and labels may differ in your interface; look for the shape and text tools.
- Draw a shape around the original phrase. Keep the text inside it readable.
- Add a visible text box with the page number, original phrase, and replacement. Place it in unused space. If the box is away from the marked phrase, connect them with an arrow or line.
- Read the page as the recipient: is it clear which phrase should change and what it should say?
Use a visible text instruction for this workflow. A recipient may overlook a collapsed note. If the outline or instruction covers other content, move it and connect it to the location with a line. On a crowded page, leave a simple mark beside the phrase and repeat the full instruction in your message.
Example: from five working days to three
The document and correction below are fictional. They are not a customer case, a recommended business deadline, or a record of an application test.
On page 2 of the two-page service-outline-v03.pdf, the Contact section contains:
Reply within 5 working days.
Outline 5 working days and add a visible instruction:
Page 2, Contact: replace “5 working days” with “3 working days”. Leave all other text unchanged.
After the correction is made in the source document, the sentence in the new version should read:
Reply within 3 working days.
That is the expected text after editing the source. Adding an instruction in Preview does not change the original sentence.
To practice, open the two-page fictional input and print it to PDF. Open your saved PDF in Preview and follow the steps above. The marked example shows how to connect a location with an instruction; it is a prepared HTML illustration, not a Preview export or screenshot. Both files contain only fictional data.
Save the copy and reopen it
Apple states that saving or exporting a PDF keeps annotations editable. Using Print → Save as PDF flattens them into the resulting PDF. Keep your working copy with editable annotations; consider a flattened delivery copy if the recipient cannot see the markup. Flattening is not security protection, a guarantee against changes, or approval of the contents.
Check the actual saved file, rather than just the window before saving:
- Open it from the location you will use when attaching it to your message.
- Go to the marked page. The original phrase, its outline, and the entire instruction must be readable.
- Compare the filename and version with your message to the recipient.
- Before relying on the request, confirm that the recipient sees the same markup. Checking on your Mac alone does not confirm how it appears on their device.
If markup is missing from your delivery copy, return to the working copy and check how you saved it. If you can see it but the recipient cannot, prepare a flattened copy by printing to PDF and repeat the checks. Do not assume every viewer displays editable annotations the same way.
Send the checked attachment with one request
Attach the checked file and repeat the instruction in your message. You can copy this fictional example:
I’m sending
service-outline-v03-correction-01.pdfwith one correction request. On page 2, in Contact, please replace “5 working days” with “3 working days”. Leave all other text unchanged. This is feedback on v03, not final approval. Please confirm that you can see the outline and the full instruction in the attachment.
For your own document, use the blank correction-request template. Replace every field with the actual details and attach the matching file before sending.
After the correction, request a new version, such as service-outline-v04.pdf. Check both the changed sentence and whether the other text remains unchanged. Keep the original request with v03; do not rename it as though it belonged to v04. If you then need a decision on the complete deliverable, continue with the client approval workflow for keeping versions distinct.
When to stop
If the PDF cannot be annotated, ask an authorized person for a usable copy. Do not bypass document restrictions. If you are unsure which version the feedback refers to, resolve that first.
The request is ready when the recipient can identify one file, one page, the original phrase, and its replacement without guessing. An outline without a readable instruction is not enough.
