Stamping basics

Stamp your first exhibit

The whole flow is three moves: drop a PDF, pick a letter, hit download. Everything runs in this browser tab — nothing uploads.

The 3-step flow

Drop a PDF onto the workspace

Drag a file onto the page, or click the drop area to browse. The document renders instantly in the preview.

Set the starting character

Type a letter (A) or number (1) in "Starting character." That's the label applied to the stamp.

Download the stamped PDF

Hit Download. The stamped file saves to your machine — the original is untouched.

Placing the stamp

Use the 3×3 Stamp placement grid to choose any of nine positions — corners, edges, or center. The live preview shows exactly where the stamp lands on the page.

Cycling through all nine spots

Color

Pick the sticker color — every option uses crisp black text on a black border. Or hit the rainbow swatch to dial in any custom color; the text auto-adjusts for contrast.

Bulk & sequencing Pro

Stamp a whole binder at once

Drop in many PDFs, let them auto-letter in sequence, reorder as needed, and export — all locally.

The queue

Drop multiple PDFs (or use + Add PDFs) and each appears in the queue on the left. Every file is assigned the next label in sequence automatically.

Start at A → files become A, B, C, … Z, AA, AB, …
Start at 1 → files become 1, 2, 3, …
The queue can be widened by dragging its right edge.

Reordering & re-lettering

Drag any queue item by its grip handle to reorder it. Labels re-sequence automatically to match the new order — slip a late exhibit into position 2 and everything downstream shifts in an instant.

Exporting

Combine OFFSeparate stamped PDFs, bundled into one ZIP download

Combine ONA single merged PDF containing every stamped document in order

Stamp every pageToggle from "Stamp first page" to "Stamp every page" to mark all pages

Why a ZIP?

Browsers block firing many downloads at once. Bundling separate files into a single ZIP guarantees every stamped document comes through in one click.

Stamp design

Make the stamp yours

Tune the convention, typography, size, and caption. The preview is pixel-faithful to what lands on the PDF.

Exhibit type

Choose the convention with one tap: Standard, Plaintiff's, Defense, State's, Petitioner's, or Respondent's. This sets both the stamp's label and the downloaded filename prefix.

Name your own

Tap ✎ Name your own in the exhibit-type grid to type any label — e.g. "Joint Exhibit" or just "Exhibit." A live preview shows exactly how it reads, and the letter (A, B, …) always appends after your text.

Starting character & sequence

Type a letter (A) or a number (1) and the queue counts up automatically — A→B→C or 1→2→3 — shown in a live preview right beside the field.

Leave blank to write in by hand

Flip Leave blank — write in by hand and the letter is omitted entirely, leaving a clean write-in line on the sticker so you can fill it in with a pen. Filenames drop the letter too (e.g. "Exhibit — deposition.pdf").

Font

Three are one tap away — Print, Hand, Block — with More revealing the rest. Each chip previews itself in its own typeface.

PrintItalic serif — formal, courtroom-classic

HandwrittenLooks signed by hand

BlockClean bold sans

StencilGovernment / evidence-room look

MarkerThick felt-tip marker

TypewriterVintage court-reporter type

Size

The Stamp size slider measures in real inches (default 1.5″ × 1″), with an in/cm toggle. What you set is the literal size embedded on the page.

Caption under the letter

A row of chips — with See more for the rest — sets the small line beneath the letter:

NoneJust the letter (default)

Page #Shows "1 / N" — updates per page when stamping every page

Case nameYour case caption, e.g. "Vega v. Helix Capital"

File nameThe document's own filename

DateToday's date

Custom textAny line you like, e.g. a case number like 24-CV-08291

Tilt

Toggle Tilt stamp slightly for a hand-applied, slightly-rotated look. Off by default for a square, aligned stamp.

Privacy & security

Your files never leave your device

Exhibit Stamper has no upload endpoint. Documents are read, stamped, and saved entirely within your browser.

How it works

When you drop a PDF, it's loaded into your browser's local memory and modified by JavaScript running on your own machine. The result is handed back to you as a download. Nothing is transmitted, because there is no server to transmit to.

Verify it yourself

Go offline

Load the page, disable Wi-Fi, and stamp a document. It still works.

Watch the network tab

Open dev tools (F12 → Network), stamp a file, and confirm no request carries your document.

Read the source

The app is a single static file with no backend. View source to confirm.
