What you'll get.
A real example of what this tool produces. Run it above with your own inputs.
Interns leave with two things: what they learned and a piece of paper that proves it. Colleges ask for an internship completion certificate before they award credit, and the intern will attach it to job applications for years. For a small studio, shop, clinic or startup that takes one or two interns a year, writing that certificate tends to be an afterthought done from memory.
This generator gives you a standard certificate in a minute. It states who the intern is, where they study if you want to include it, the role, the dates and the calculated duration, the project or work, and a performance line you choose or leave out. Print it on your letterhead or save it as a PDF, then sign it.
The tool is free, needs no sign-up and runs in your browser. It comes from Neweb, the AI website builder for small businesses, which has a free plan and paid plans from $9/month billed yearly ($19 month-to-month). Colleges and future employers will look your organisation up, so it helps to have a website that shows who you are; Neweb builds one from a short description.
How to use the internship certificate generator
Enter your organisation name and address.
Add the intern name, and the course and college if the certificate is going to a placement office.
Fill in the role, team, start and end dates and a one-line summary of the work done.
Choose the mode and a performance line, or omit both.
Add the signatory and certificate number, click Preview certificate, then print, sign and stamp.
Why this matters for your business
Colleges need it for credit. Many courses make an internship compulsory and will not record it without a certificate from the host organisation showing the dates and the nature of work.
It reflects on you. A clear, correctly dated certificate with a certificate number tells the next reader that your organisation is real and organised, which matters when you want good interns to apply next year.
When to use an internship certificate
Issue it on or after the last day of the internship, once the work is handed over. For an intern you are converting to an employee, follow it with an offer letter. For a former employee rather than an intern, use the experience letter generator. If the college has its own form, fill that in and attach this certificate as supporting proof.
Tips for better results
- Use the exact dates from your attendance or onboarding records; colleges count weeks.
- Describe the work in concrete terms, such as the project or tools used, rather than "various tasks".
- Number certificates in sequence and keep a register so you can confirm one when a recruiter calls.
- If the internship was unpaid or paid a stipend, you do not need to state that on the certificate.
- Email a signed PDF as well as giving a paper copy; interns lose paper.
Example
A real-world walkthrough
Pixel Orchard Studio, a design studio in Bengaluru, hosted Aditi Rao as a Graphic Design Intern from 1 June to 31 July 2026. Her college needs a completion certificate before the new semester.
The creative director, Karan Shetty, enters the studio details, Aditi as a student of B.Des Communication Design at Srishti Manipal Institute, the Brand Design team, both dates and the line "social media creatives and packaging mock-ups for three client brands". The tool computes the duration as 2 months. He keeps the "good" performance line, adds certificate number PO/INT/2026/012, previews, prints on letterhead and signs. Aditi gets the paper copy and a PDF by email.
Frequently asked questions
What should an internship certificate include?
The name and address of the organisation, the intern name, the internship role, the start and end dates or total duration, a short description of the work or project, optionally a comment on performance, the date of issue, and the name, title and signature of the person issuing it. A certificate number makes later verification easier.
Who issues an internship certificate?
The organisation where the internship took place: the founder, a manager, HR or the intern supervisor, on the organisation letterhead. An intern cannot issue one for themselves. This tool formats the certificate for the organisation to sign; a certificate filled in by the intern with a copied signature or seal is a forgery.
What is the difference between an internship certificate and an internship offer letter?
The offer letter is issued before the internship starts and sets out the role, dates, stipend and expectations. The certificate is issued at the end and confirms that the internship was completed. Colleges often ask for both: the offer letter for approval and the certificate for credit.
How is the internship duration calculated?
The tool counts from the start date to the end date, both included. Full calendar months are shown as months, for example 1 June to 31 July is 2 months, with any extra days added. Shorter internships are shown in weeks when the days divide evenly, otherwise in days.
Can a small business or startup issue an internship certificate?
Yes. Any genuine organisation that hosted the intern can issue one, including sole proprietors and early-stage startups. Use your letterhead, sign it and give contact details so the college can verify it. Some universities also ask for the organisation registration details; add them to your letterhead if so.
Can I issue a certificate before the internship ends?
Not a completion certificate. The tool blocks end dates in the future for that reason. If the intern needs proof while the internship is under way, write a short letter stating that they are currently interning with you since the start date.
