How to increase PDF size
- Choose your PDF.
- Pick the size your form asks for, such as 100 KB, 200 KB or 1 MB, or type your own.
- Press Increase size and download. The result shows the new size.
Some forms reject files that are too small. WaterPDF adds empty space at the end of the PDF until it reaches the size, so pages, text, links, forms and quality stay exactly as before. The size is counted with 1 KB = 1,024 bytes, so it is at least the limit whichever way the form counts.
Before you get started
How do I increase a PDF size to 200 KB?
Choose the PDF above, pick 200 KB and press Increase size. The download is just over 200 KB and looks exactly the same.
Will the quality or content change?
No. Nothing in your pages is changed or redrawn. Only empty space is added inside the file, which PDF readers skip.
The form says between 100 KB and 200 KB. What do I choose?
Choose a size in the middle, such as 150 KB. If your PDF is too big for the maximum, use Compress PDF instead.
Can I increase a scanned PDF or a JPG made into a PDF?
Yes, any PDF works. To make photos into a PDF first, use JPG to PDF, then increase its size here.
Pdf ka size kaise badhaye?
Upar PDF chuniye, jitna KB chahiye (jaise 200 KB) chuniye aur Increase size dabaiye. File utni badi ho jaati hai, pages bilkul waise hi rehte hain.
