Compress / Reduce a PDF When Documents Exceed The File Size Limit

Last Update: February 9, 2022

Most courts impose a 25MB file size for PDF documents, and a 35MB limit for the entire envelope. Anything exceeding that limit prevents the submission of the filing. (The Fresno Superior Court allows for 100MB file and envelope size limits while LASC Civil has a limit of 200MB.)

The courts do not impose a limit to the number of documents a filer may attach to a filing as long as they do not exceed the two file size limitations above.

Reduce, compress, or optimize file sizes

If the file size of a document exceeds the 25 MB file size limit, then the user may need to do some work to reduce, compress, or optimize the file size. Otherwise, the filer might want to consider splitting up the document into two parts for filing, and give each new PDF it’s own, separate caption page. However, the filer might want to reach out to the specific court’s filing clerk first to advise on if splitting a document is allowed for their court.

Before beginning, it’s important to note a few things about compressing documents and files sizes.

  1. There’s a limit to how much a file can be compressed. A 100mb document may not be able to be compressed to a proper size. If a user compresses a file, and it’s still larger than 25mb, then they will need to try re-scanning the document, and then, even possibly re-compressing the file.
  2. 1mb does NOT equal 1 page. A filer is not limited to a number of pages in a PDF as long as the PDF file size is 25mb or smaller.
  3. Using the e-filing system to convert documents to be text searchable may increase the file size.

Convert the documents

If the document was created using a Word Processor like Microsoft Word or Word Perfect, there is no need to print the document, sign it, then scan it. It is better to electronically sign that document using a /s/ followed by the attorneys name on the signature line. Then simply convert the document to PDF. Documents converted to PDF from a word processor always result in a very small file size.

Optimize scanner settings

It is rare that there is a need to scan documents in color or high resolution for the purpose of e-filing. Ideally, its a best practice to scan documents at no more than 300 DPI and in black and white or grey scale.
