How to Scan a Signed Offer Letter for HR

An offer letter is the one document in the hiring process where the details matter most — salary, start date, notice period, probation terms. Employers usually ask you to sign and return it within a few days, and the signed copy becomes the record both sides rely on. A proper scan protects you: if a term is ever disputed, your PDF shows the exact version you signed, not a memory of it. This guide covers the offer letter itself — the scan, the signature, and the send-back — rather than the wider new-hire paperwork pack, which has its own checklist.

Scan, sign, send: the 3-step flow

1. Read the letter first. Check the salary, job title, start date, work location, notice period, and probation length against what was discussed. Flag anything different with the recruiter in writing before you sign — a signed letter is much harder to renegotiate.
2. Sign every page that asks for it. Most offer letters need a signature on the last page only, but some ask you to initial each page. Sign with a dark pen on paper, or use a proper e-signature if the employer accepts one — a typed name in a fancy font is not a signature.
3. Scan every page, in order. Include the annexes, terms-and-conditions pages, and any benefits summary attached to the letter. A single multi-page PDF, pages in order, is what HR expects.
4. Name the file clearly. Use a format like offer-letter-acme-designer-signed-2026-11-06.pdf so HR can find it without opening it.
5. Send it to the right person. Reply to the recruiter or hiring manager who sent the letter, confirm in the email that you accept the offer as written, and keep the sent email as your record.
6. Keep your own copy. Save the signed PDF in a folder with the rest of your job paperwork — contract, payslips, and tax documents — so you can find it months later.

What HR actually needs in the scan

• Every page, no gaps. A missing middle page is the most common reason HR asks for a re-send. Count the pages before you scan and after.
• A legible signature page. The signature, date, and printed name must be readable — HR files this page as proof of acceptance.
• Straight edges and full margins. Text cut off at the edges looks unprofessional and can hide terms. Frame the whole page with a small margin around it.
• Readable small print. Terms and conditions are often printed smaller than the main letter. If the text is blurry at normal size, move the camera closer or add light — do not send a scan you cannot read yourself.
• One PDF, not five photos. HR systems and applicant tracking software handle a single PDF far better than a set of JPGs in an email.

Common mistakes to avoid

• Scanning only the signature page. HR needs the whole letter, not just the page you signed. A partial scan always comes back with a request for the rest.
• Signing before reading. Check the notice period and probation terms before you sign. Anything you disagree with should be raised first, in writing.
• Sending a photo instead of a scan. Phone photos skew perspective, add shadows, and often crop the edges. A proper scan with edge detection keeps the letter looking like a document, not a snapshot.
• Forgetting the annexes. Benefits summaries, confidentiality clauses, and non-compete pages attached to the letter are part of the agreement — scan them too.
• Deleting your copy. Keep the signed PDF and the email thread. If payroll, start date, or role details ever change, that file is your evidence.

Frequently asked questions

Should I scan the offer letter before or after signing it?
Both. Scan the unsigned letter so you can read it properly on a big screen, then sign it and scan the signed version — the signed scan is the one HR files.

What file format should I send to HR?
A single multi-page PDF. It preserves page order, prints cleanly, and opens on every HR system. Avoid sending separate JPG photos.

Can I sign an offer letter digitally?
Usually yes, if the employer accepts it — a drawn signature or a proper e-signature tool works. If in doubt, ask the recruiter before you sign; some employers still want ink on paper.

What if the offer letter differs from what was discussed?
Do not sign it yet. Email the recruiter, point out the specific difference, and ask for a corrected letter. Keep that email with your copy of the signed version.

How long should I keep my signed offer letter?
Keep it for the whole time you work there, and for at least a year after you leave. It records your starting salary, role, and terms, which matter for references, disputes, and future negotiations.
