Increase PDF Size to 100 KB
Your certificate or marksheet PDF is 40 KB and the form says minimum 100 KB. This page is set to raise it to 100 KB with invisible padding, so the document you upload is the one you have, just heavier.

Max 95 MB per file· Up to 20 files· Deleted after 30 minutes
Files are processed on our servers and deleted after 30 minutes.
Padding adds invisible data and leaves every page exactly as it looks. Higher image quality re-renders scanned pages at more DPI, which also makes them sharper.
Pages are re-rendered at this DPI. 300 is print quality; go higher only if the target is still not reached.
At least stops as soon as the file passes the target. Exact pads to within 1 KB of the number you entered.
How to use this tool
- 1
Upload the PDF
Add the file that was rejected for being too small, or several at once; up to 20 PDFs, 95 MB each.
- 2
Leave 100 KB in place
Target size is 100 KB, Increase by is Padding and Size is As close as possible. If the form gives a range instead, type a number inside it.
- 3
Increase and download
Press Increase size, confirm the new size shown beside the file, and upload it to the form.
Why forms in India say min 100 KB
The phrase turns up most in Indian application forms: state recruitment boards, university admissions, scholarship schemes and exam registrations often list a size window for each uploaded document, and some put the floor at 100 KB. The intent is legibility. A scanned A4 certificate at a readable resolution is usually well above 100 KB, so a smaller file looks like a thumbnail or a photo of a photo. Rules differ between notices and even between documents in the same form, so read the exact line for the document you are uploading.
Where the rule misfires is with born-digital files. A marksheet downloaded from DigiLocker or a university results page, or a certificate exported from Word, is text and vector graphics, and it often weighs well under 100 KB while being perfectly sharp. Rescanning a printout of it would only make it worse.

Upload errors after you increase PDF size to 100 KB
"File size must be minimum 100 KB" on a file that reads 100 KB
The portal counts kilobytes differently or rounds down. Set Target size to 103 and increase again.
"File size should be between 100 KB and 200 KB"
Type a number in the middle, such as 150, so rounding at either end cannot push the file outside the window.
"Only PDF files are allowed"
Check the extension is .pdf and not .PDF.jpg or a renamed image. Convert photos to PDF first, then increase the size.
The size is right but the upload still fails
Some forms also cap page count or check that the file is not password protected. Remove the password and keep only the pages the form asks for.
What 100 KB means to a portal
The IEC introduced the kibibyte, KiB, in 1998 to name 1,024 bytes and leave the kilobyte at 1,000, but most software and most upload forms still write KB for either. Since you cannot see how a portal counts, aim a few kilobytes above the floor when a minimum is all that matters, and toward the middle when there is a maximum close by.
The same logic runs the other way when a form caps files at 100 KB: then you want compress PDF to 100 KB, which shrinks scans while keeping text readable. For images that must reach 100 KB rather than PDFs, the image version of this tool handles JPG and PNG.
Increase PDF size to 100 KB questions
Why does my 100 KB PDF show as 98 KB on another computer?
Windows counts 1 KB as 1,024 bytes, while macOS Finder has counted 1 KB as 1,000 bytes since Mac OS X 10.6 Snow Leopard. The same file can therefore show two different numbers. If a portal rejects a file that looks like exactly 100 KB, enter 103 to clear both definitions.
Should I choose At least the target or As close as possible for 100 KB?
For a plain minimum, either works; this page uses As close as possible so the result sits right at 100 KB. If the form also has a low maximum, such as 100 KB to 120 KB, As close as possible keeps you safely inside it.
Can I increase a PDF of only 8 KB to 100 KB?
Yes. Padding can add any amount, so even a very small file reaches 100 KB with its single page unchanged. Glance at the page first to be sure it is not blank, since that is what tiny files often turn out to be.
Is it better to rescan the certificate at a higher resolution instead?
If the scan is faint or blurry, yes, because the form's reviewer will read it too. A clear scan at 200 to 300 dpi usually clears 100 KB on its own; if it does not, padding covers the rest.
I have a JPG of the document, not a PDF. What do I do?
Turn the photo into a PDF with JPG to PDF first, then bring the PDF here. A phone photo usually produces a PDF well above 100 KB anyway.
