PDF is a portable document format that helps to exchange documents efficiently. One can print or view it online. One can preserve all types of text and images in PDFs. It also helps to maintain graphics' visual appearance and accommodates large and small files.

Multiple devices and Operating systems support pdf view. We can edit text, copy and paste it, and PDFs have a clean layout. Since PDFs can also be password-protected, one can often not copy them. They protect your content (pictures and documents).

When there is a deadline, picture editing, whether done for personal enjoyment or work, always gets sloppy or, worse still, damages the already-existing document. It's crucial to be highly accurate with the size and positioning of your object in the PDF if you don't want it to have an unsightly format. The overall size of the document will depend on how the image sizes are edited in a PDF.

If you plan to mail a document larger than the allotted size, let's, say, 15MB, it won't be easy to complete the process. Even though PDFs can handle large files, sharing and exporting them is not always straightforward.

Why is Resizing Important?

  • Uploading pictures on social media, Web- we all love clicking selfies, sharing, and uploading them as our profile pictures. It is frustrating when you can't upload your favourite picture as your display picture because the app has size limit restrictions. 
  • Uploading images and documents on the website- When uploading files to a website, keep in mind that it will take longer to load larger files. Most websites won't accept larger files since doing so could cause the site to lag, take longer to load, crash, or put extra strain on the server.
  • Sharing files(images/docs) via mail and apps- Many social media apps, like WhatsApp and Snapchat, have size restrictions for exchanging images and documents.
  • If you wish to share a photograph on Snapchat, it must be 3 MB. Moreover, sharing and downloading WhatsApp files larger than 25Mb takes a lengthy time. Mailing files often cause hassle significantly when it exceeds the size limit. Sharing important documents usually takes its course through the mail, but then again, there are always some issues. 
  • Adding a larger image to your document does not fit the print format. The same goes for smaller-size documents. Let's say you're filling out an application form online, and you are supposed to add a PDF of your sign in the form, but the file size should be no more than 2-5kb, and the file format should be in pdf.  

These are just some of the situations we have all faced. It is where image and pdf resizing help us out. Finding the best site for you is our work.
