How To Reduce PDF File Size Below 100KB – Compress Files in Seconds
File size makes a huge difference in online documents. If you want to add an awesome PDF infographic, for example, you want the file to be as small as possible. That way your website’s pages load quickly on mobile devices and PCs. At PDFSimpli, we can help you reduce the size of your PDF documents while also maximizing quality and clarity. Here’s what to do to reduce PDF file size below 100 kB.

How To Compress File Size Below 100 kB Online
One way to have an incredible PDF that takes up virtually no space is to compress it. Compressed PDFs still contain the same document information, text, images, and other elements, but they organize the data in a way that is more efficient. Our PDFSimpli Compress PDF tools make short work of shrinking PDF files.
- Visit our PDFSimpli website from your PC, laptop, tablet or smartphone.
- Select the Compress PDF tool.
- Upload your document by dragging the file onto the screen or choosing it from a save folder.
- Choose the compression option you want to use.
- Pick a location to save the compressed PDF. When you’re ready, click Compress.
- Your compressed PDF is now ready to send to anyone!
The Compress PDF tool works on documents of many different sizes. You can take a 1 MB file and make it much smaller. Our tools can even save you space with files that are over 1 GB in size. Best of all, compressing a PDF online means you don’t need to download or install any programs on your computer.
How To Reduce File Size Without Losing Quality Below 100 kB
There are a lot of different options for compressing PDFs. Here are three ways to reduce PDF file size without losing quality. Thanks to our PDFSimpli tools, you can use them online anytime.
Method 1: Use a Lower Compression Ratio
Compression works by replacing repeated code. It’s kind of like replacing the words “portable document format” with the letters PDF. This works great for things such as text, but images can get a little tricky because of the huge variety of colors and pixels available. If you want to be extra careful with image quality, choose a lower amount of compression.
Method 2: Convert PDF to Word
Optical character recognition saves a lot of space by converting words in a PDF file to digital text. Text files in Word format are tiny, often taking up 10-20 kB or less. This option is a great way to send documents and company records to coworkers. Here’s what to do:
- Choose the Convert PDF to Word tool from our PDFSimpli website.
- Upload your file. You can drag it onto the screen, select it from a save folder on your computer or look for it in DropBox or Google Drive.
- Let our high-tech OCR analyze the text carefully. If you want, you can even make edits.
- Click Convert.
- Your PDF is now available as a Word file!
One of the biggest benefits of using this method to convert PDF to Word is the amount of editing you can do afterward. If you want to change the formatting, fonts, text size, text color, and other elements, it only takes seconds. You can add headings, paragraphs, and styles, too. The only catch is that the person who receives the file needs to have Microsoft Word installed.
Method 3: Convert PDF to Excel
This option works best when you have a form or a spreadsheet you want to convert. Similar to the Convert PDF to Word option, Excel files have a very small size. This makes them perfect for storing invoices, tables and other data. Using PDFSimpli, the process is fast, and it’s free!
The best type of compression depends on the kind of content your PDF has. For example, if you’re sending black and white text, you can select higher compression rates without sacrificing quality. For something with lots of images, you may want to select a lower compression to make sure the finished photos remain amazing.
