What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Love the service and how it integrates with Zapier - it has saved me tons of time in manual repetition for filling out intake, invoicing and legal documents and I love the send to sign feature. Would like a little more functionality in the app, like having the ability to sign docs directly instead of using mobile browser, but overall it functions beautifully. Best value for this type of service hands-down. As a small business, the price-point is phenomenal! Highly recommend PDFfiller!!

I do think that is for the more tech savvy individuals that deal with PDFs on a daily basis. There were a few things that I had to figure out, but overall I give it 5 stars because it is a lot easier to use and edit documents my way than it is for me to do in Adobe PDF. Thanks PDF Filler.

How to Reduce Excel File Size to Under 100 mb

Reducing the size of your Excel file to under 100 mb can help improve its performance and make it easier to share. Follow these steps to reduce the file size:

01
Remove unnecessary data: Delete any unused worksheets, rows, or columns in your Excel file. This will help reduce the file size by removing unnecessary data.
02
Compress images: If your Excel file contains images, you can compress them to reduce the file size. Select the image, go to the 'Format' tab, click on 'Compress Pictures', and choose the desired resolution.
03
Remove hidden data: Excel files can sometimes contain hidden data such as comments, formulas, or formatting that are not visible. To remove hidden data, go to the 'File' tab, click on 'Check for Issues', and select 'Inspect Document'. Choose the options you want to inspect and click on 'Inspect'. Then, click on 'Remove All' to remove the hidden data.
04
Reduce formatting: Complex formatting, such as conditional formatting or cell styles, can increase the file size. Consider simplifying the formatting or removing unnecessary formatting to reduce the file size.
05
Save as a different file format: If reducing the file size using the above steps is not enough, you can try saving the Excel file as a different file format, such as CSV or XLSB. These file formats are generally more compact than the default XLSX format.
06
Use external tools: If none of the above steps help in reducing the file size to under 100 mb, you can consider using external tools or software specifically designed for compressing Excel files. These tools often offer advanced compression techniques to further reduce the file size.

By following these steps, you can successfully reduce the size of your Excel file to under 100 mb and optimize its performance. Remember to save a backup of your original file before making any changes.
