About ShrinkWrit

What it does

ShrinkWrit compresses documents and images down to a target file size. You give it a size in megabytes — the one your court published, or one you type in — and it works toward that number rather than asking you to guess at quality settings. Everything runs in your browser; nothing is uploaded.

Your original file is never modified. Output is always a new download, so the file you started with stays exactly as it was.

What it deliberately does not do

ShrinkWrit provides technical file compression only. It does not tell you how, when, or what to file, does not interpret court rules, and does not give legal advice. Those are questions for your court’s clerk or an attorney, and a compression tool has no business answering them.

How the size limits are tracked

Every limit on this site comes from a single data file, and every court page shows the date that figure was last checked along with a link to the court’s own notice. Limits change without much announcement, so treat what you see here as a starting point and confirm against the source before you file. The court directory lists everything currently tracked.

Federal limits in particular are set district by district rather than nationally. There is no single CM/ECF number, and neighboring districts routinely differ.

Evidence and exhibits

Lossy compression alters a file. If the file is evidence, that alteration can raise authentication questions, and altering electronically stored information can implicate spoliation. ShrinkWrit offers a lossless mode, keeps your original untouched, and shows SHA-256 hashes of both the input and the output so you can document precisely what changed. What you do with a compressed exhibit remains your call and your responsibility — but you should at least be able to see what happened to it.
