Add one or more photos or scans of your certificate, marksheet or ID. Each picture becomes one page. Your pictures stay on your phone and are never uploaded.
Exam portals set their own rules for PDF size, pages and clarity. Always match the instructions in your own notification. If the form states a KB limit, this tool keeps the file safely inside it whichever way the portal counts a KB.
What is an image to PDF converter?
An image to PDF converter turns your photos or scans into one PDF file. Online exam forms often ask for a certificate, marksheet or ID card as a PDF under a size limit, such as 100 KB or 200 KB. Your phone photos are usually several MB, so the form rejects them.
This image to PDF converter fixes that. Add your pictures, set the maximum KB, and tap one button. You get a single PDF that fits the limit, and you can download it straight to your phone.
Use it to convert JPG to PDF, PNG to PDF or WebP to PDF. It also works as a simple tool to merge images into one PDF and to reduce PDF size for exam forms, job applications and college admissions.
How to use this image to PDF converter
a) Add your pictures. Tap the box and choose one or more photos or scans. Each picture becomes one page. You can add up to 10 pictures.
b) Put the pages in order. Use the arrows to move a page up or down. Tap the rotate button if a page sits sideways, and the cross to remove a page.
c) Set the maximum size. Type the limit from your form in KB, or tap a quick button such as 100 KB, 200 KB, 300 KB, 500 KB or 1 MB. Leave it empty if there is no limit.
d) Set a minimum size only if your form asks for one.
e) Choose the page size and margin. Keep A4 with a small margin if you are not sure.
f) Tap “Create PDF“. The tool shows the number of pages, the file size and a clarity rating.
g) Tap “Download PDF” and upload the file to your form.
All of this happens inside your browser. Your pictures are not uploaded to any server.

What the settings do
Maximum PDF size
The tool tries the sharpest quality first. If the file is too big, it lowers the quality and size step by step until the PDF fits your limit. You get the clearest pages that the limit allows.
Minimum PDF size
Some forms reject a file that is too small. If your PDF comes out below the minimum, the tool adds harmless filler data to the file so it reaches the minimum. Your pages do not change.
Page size
A4: the standard choice for documents. Wide pictures turn the page sideways on their own.US Letter: use it only if a form asks for it.Same shape as each picture: each page matches its picture, with no white space around it.
Margin
Choose no margin, a small margin or a normal margin. A small margin is a safe choice for certificates.
Scan look
Choose “Cleaner scan” to turn a document photo into grayscale with whiter paper. The text looks sharper and the file gets smaller, which helps with tight KB limits. Keep the original colours if your document has stamps, seals or colour photos that must stay clear.
Before you apply, check that you are eligible with our age calculator for government exams.
What makes this converter different
- It keeps the file inside your KB limit. Portals count a KB in different ways. The tool keeps the file inside the range whichever way the portal counts.
- It fixes files that are too small. It can add filler data to reach a minimum size.
- It tells you about clarity. The result shows Sharp, Good, Readable or Low, so you know if the text will be easy to read.
- It cleans scans. One option makes a phone photo of a document look like a clean scan.
- It works on your phone. You can add photos, put them in order and download the PDF without any app.
Tips for a clear PDF under a small KB limit
- Take photos in bright light with the paper flat. Avoid shadows and glare.
- Crop out the table or floor around the paper before you add the picture.
- Choose “Cleaner scan” for printed or handwritten documents. It saves a lot of space.
- Add only the pages you need. Ten pages under 100 KB will look blurry, but two pages look fine.
- Make one PDF for each document if the form has separate upload boxes for each.
- Open the downloaded PDF and zoom in once to check that the text is readable.
- If the tool says the clarity is low, raise the limit or remove a page.
Documents you can turn into a PDF
- 10th and 12th marksheets and certificates
- Graduation degree and marksheets
- Caste, income and EWS certificates
- Date of birth proof and ID cards
- Experience letters and other supporting documents
Always check your exam notification to see which documents the form needs and how many pages each file may have.
Common reasons a PDF upload fails
- The file is above the maximum KB or below the minimum KB.
- The pages are too blurry to read.
- The file is not a PDF when the form asks for a PDF.
- The form allows only one file, but you made several.
- The portal has its own limit on pages.
This tool checks the size and range for you and shows a tick or a cross.
