PDF too large for court e-filing? Compress and merge exhibits locally.
Meet CM/ECF, CE-File, and State Court PDF Size Limits Without Uploading to the Cloud
Court e-filing portals reject PDFs that exceed strict size limits -- US federal courts cap at 50MB per filing (many limit individual documents to 35MB or even 600KB), UK CE-File, India e-Courts, and state court systems each impose their own rules. Diwadi compresses, merges, and protects your court PDFs on your computer. Attorney-client privilege and sealed documents never leave your device.
Court E-Filing PDF Size Limits by Jurisdiction
| Court / System | Per Filing Limit | Per Document Limit | Accepted Formats | Notes |

| Australia Federal Court | 50 MB | 10 MB | eCourtroom and eLodgment systems; PDF/A preferred for archival submissions |
PDF/A Requirements for Court Archival
Some courts — particularly federal courts, appellate courts, and jurisdictions with long-retention mandates — require PDF/A format rather than standard PDF. PDF/A is an ISO-standardized archival format that embeds all fonts, color profiles, and metadata to ensure the document renders identically decades later.
PDF/A-1b
Basic conformance level. Embeds all fonts, disallows encryption and external content. Required by many US federal agencies and some courts for permanent records.
Standard legal filings, permanent court records
PDF/A-2b
Extended conformance supporting JPEG 2000 compression and transparency. Smaller file sizes than PDF/A-1b while maintaining archival compliance.
Exhibit-heavy filings, image-dense documents, appellate records
Check your jurisdiction's local rules before converting to PDF/A. Some courts require it; others prohibit encrypted PDFs regardless of archival format. Diwadi converts to PDF/A-1b and PDF/A-2b locally, preserving document integrity without cloud upload.
Assembling Multi-Exhibit Filings
Court filings often require combining multiple documents into a single PDF — a motion with exhibits, a trial brief with appendices, or an appellate record with the clerk's transcript, reporter's transcript, and all attached exhibits. Getting the order and total size right before upload saves rejected filings and deadline extensions.
Gather All Exhibits
Collect scanned exhibits, declarations, contracts, photographs, and transcripts. Scanned documents are often oversized -- a 300 DPI scan of a 20-page contract can exceed 40MB before any processing.
Compress Individual Documents First
Compress each exhibit individually before merging. A 15MB scan compressed to 3MB, combined with five other similarly compressed exhibits, stays well within a 50MB filing limit.
Merge in Proper Order
Combine documents in the order specified by court rules -- typically motion first, then exhibits in alphabetical or numerical order (Exhibit A, Exhibit B, etc.).
Verify Total Size
Check the merged PDF's total size against your court's filing limit. If it exceeds the limit, further compress the most image-heavy exhibits or split the filing into allowed volumes.
Password Protecting Confidential Court Filings
Courts sometimes permit or require password protection for documents filed under seal, protective orders, or containing PII that will be served to specific parties. Understanding when and how to apply PDF passwords for legal filings is important.
Sealed Documents
Documents filed under seal may be submitted with password protection when the court has authorized restricted access. The password is typically provided to the court separately, not in the filing itself.
Protective Order Documents
Exhibits subject to a protective order marking them confidential, highly confidential, or attorney's-eyes-only may be transmitted with password protection between parties per the order's terms.
Service Copies with PII Redaction
When serving copies containing social security numbers, financial account numbers, or minor children's names, some practitioners password-protect service copies while filing redacted versions publicly per FRCP 5.2 / local rules.
Password protecting a court filing does not guarantee the court's ECF system will accept it. Verify with your court's CM/ECF help desk whether password-protected PDFs are accepted before filing. Many courts reject encrypted PDFs outright.
Why Online PDF Tools Are Dangerous for Legal Documents
Attorney-Client Privilege
Uploading a client's legal documents to a third-party PDF compression website creates a transmission record and potentially waives privilege. Courts have addressed whether cloud-processing of privileged documents constitutes disclosure to a third party. The safest position is offline processing.
Sealed and Confidential Documents
Documents filed under seal, subject to protective orders, or marked attorney's-eyes-only must not pass through unknown servers. Processing them offline with Diwadi means they never leave your computer.
PII in Court Documents
Legal filings routinely contain social security numbers, financial account data, minor children's names, medical records, and other PII that courts require to be redacted from public filings. Even unredacted versions sent to opposing counsel must be handled with care.
Opposing Counsel and Sanctions Risk
Accidental disclosure of privileged or confidential material through an insecure upload tool can result in sanctions, disqualification motions, or mandatory disclosure to opposing counsel. The risk-reward ratio for using free online tools with client documents is extremely unfavorable.
No Control Over Data Retention
Free PDF tools retain uploaded documents for hours, days, or indefinitely for product improvement. The terms of service almost universally disclaim liability for data breaches. Your clients' case strategy, financial information, and personal data deserve better.
How to Prepare Court Filing PDFs with Diwadi
Download Diwadi
Install Diwadi on your Mac or Windows computer. No account required. All PDF processing happens locally — nothing is transmitted to any server.
Compress Oversized Exhibits
Drop each exhibit PDF into Diwadi and compress to your target size. For a court with a 35MB per-document limit, aim for 25MB or less to leave headroom. Diwadi finds the optimal compression level that keeps text sharp and images legible.
Merge Exhibits into a Single Filing
Use Diwadi's PDF merge tool to combine your motion, brief, or petition with all exhibits in the correct order. Review the merged PDF's page count and total file size before proceeding.
Protect and File
If required, apply password protection for sealed or confidential filings. Upload the prepared PDF to CM/ECF, CE-File, or your state court portal. All documents stayed on your computer throughout.

Frequently Asked Questions
What is the PDF size limit for CM/ECF federal court filings?
The federal CM/ECF system has a technical limit of 50MB per filing, but individual district courts set their own local rules for per-document size limits. Many courts limit each attachment to 35MB. Some courts that still use older versions of CM/ECF may cap individual documents at 10MB. Always check your specific court's local rules and CM/ECF requirements before filing. If your exhibit exceeds the limit, you must split it into separate volumes.
What PDF size limit does California state court e-filing impose?
California's Online Court and Self-Help Services (OCAP) system and the various permitted electronic filing service providers (EFSPs) typically accept PDFs up to 25MB per document and 50MB per filing. However, courts in the same state can differ -- some superior courts using different portals have lower limits. The California Courts website publishes local rules for each court. Pro se portals sometimes cap uploads at much lower limits, as low as 600KB for certain form submissions.
Does the court require PDF/A format for filings?
It depends on the jurisdiction. US federal courts through CM/ECF generally accept standard PDF, not PDF/A specifically, but many government agencies that receive court-related documents prefer or require PDF/A for archival records. The UK National Archives specifies PDF/A for permanent records. Some courts require PDF/A for appellate records. Check your court's standing orders, local rules, or electronic filing guide. If in doubt, PDF/A-1b is a safe choice as it is the most broadly compatible archival format and is accepted wherever standard PDF is accepted.
Can I password protect a PDF before filing it in CM/ECF?
Generally, no. CM/ECF and most court e-filing systems reject password-protected or encrypted PDFs. The court's technical standards explicitly prohibit encryption so that the clerk's office can access documents. Sealed documents are handled by the court system's access controls, not by PDF passwords. If you believe a specific submission requires password protection, contact your court's CM/ECF help desk before filing. Submitting an encrypted PDF may result in a rejected filing and a missed deadline.
How do I reduce a scanned court document PDF below the size limit?
Scanned PDFs are almost always image-based and can be significantly compressed without losing legibility. A 300 DPI color scan of a text document is usually overkill -- 150 DPI grayscale is sufficient for most scanned legal text and produces files roughly 75-85% smaller. In Diwadi, you can compress the scanned PDF to a target file size, and Diwadi will adjust the image quality to meet that target while keeping text readable. For a 40MB scan that needs to be under 10MB, this approach works well.
What is the correct way to merge exhibits for a federal court filing?
Federal court local rules vary, but the common approach is: file the main document (motion, brief, or petition) as the primary document and attach exhibits as separate attachments labeled Exhibit A, Exhibit B, etc. Some courts prefer all exhibits merged into a single exhibit compendium PDF with a table of contents and exhibit tabs. Others require each exhibit as a separate upload with a descriptive filename. Read your district court's standing orders and CM/ECF user guide. When in doubt, call the clerk's office -- they prefer a phone call to a rejected filing.
Is it safe to use an online PDF compressor for court documents?
No. Court documents routinely contain attorney-client privileged communications, sealed information, confidential personal data (social security numbers, financial records, medical information), and case strategy. Uploading these to a third-party online PDF tool transmits them to an unknown server operated by a company whose data retention, security practices, and personnel access controls are outside your control. In addition to the practical data security risk, there are ethical and evidentiary questions about whether uploading privileged documents to a third party constitutes a waiver. Use a desktop tool like Diwadi that processes files locally.
How do I handle a PDF exhibit that is still too large after compression?
If an exhibit PDF exceeds the per-document limit even after compression, you have several options. First, if the exhibit is a multi-page scanned document, split it into two or more volumes (e.g., Exhibit A - Vol. 1, Exhibit A - Vol. 2). Many courts explicitly allow this in their local rules. Second, check whether the court permits native document submission -- a Word document or spreadsheet may be smaller and more accepted than a scanned version. Third, contact the clerk's office; courts sometimes issue filing orders for oversized records.
What PDF format should I use for court exhibit photographs?
Photographic exhibits embedded in PDFs should be compressed to a balanced quality -- high enough to show relevant details (damage, signatures, scene conditions) but not so high that the file becomes unmanageable. For most purposes, a 150 DPI JPEG-compressed embedded image is sufficient. If the photograph is critical evidence where fine detail matters (crime scene, document authentication, product liability), file at higher resolution and note the reason in your cover sheet. UK CE-File also accepts standalone JPG files as exhibits.
Can I compress a PDF without losing the ability to copy text (non-scanned PDFs)?
Yes. Diwadi's PDF compression for native (non-scanned) PDFs compresses embedded images and optimizes the file structure without affecting text layers. The resulting PDF remains text-searchable and copy-pasteable. This is important for court filings because CM/ECF requires that text-based PDFs be searchable -- you cannot file a text document as a scanned image PDF if you have access to the original text-based PDF.
