Trim Down Large PDF Files with These 5 Simple Tips

Tip 1. Use The “Save As” Command

click save as

Regardless of the application that you are using to open your PDFs, there will always be the option of “Save As,” which will save your file as a new one, eliminating unnecessary data that may have been stored in the original document.

Tip 2. Compress And Downsample PDF Images

Some applications, such as Adobe, can compress PDF images, which can be very large and considerably increase the megabytes that the file occupies. Thanks to this function, the size of PDF documents can be reduced considerably.

Tip 3. Choose The Right Colour Space

choose the right color space

The color space of the PDF can mean a size difference between CMYK and RGB. If you do not plan to print your file, you can look for a program that helps you change the color space from CMYK to RGB since the latter option will consume less storage space.

Tip 4. Subset Your Fonts

subset your fonts

Some applications will allow you to subset the embedded fonts. This option will help reduce the size of your PDF files, thanks to the fact that you will only link the characters of the fonts present in the document when activated.

Tip 5. Remove Unnecessary Frills

It would be best if you recognized your PDF's purpose. If you will not require a document with high-definition images or make high-quality prints, you can attach non-HD images in advance.

Similarly, if your documents only contain text, you can reduce the page size from the beginning; These types of details can save you a lot of headaches, as they will cause the size of your PDF to decrease.

Conclusion

PDF files have great advantages, but one of the disadvantages that they can have is that they can be quite large if they contain graphic information. However, this problem can be easily solved, thanks to the fact that you can use tools or applications to compress it and also other practical resources that will help you make your file take up less space.
