Form fields

List all fields

fields = exis_pdfeditor.list_fields("form.pdf")

for field in fields:
    print(f"  {field.name} ({field.type}): {field.value}")

result = exis_pdfeditor.fill_form(
    "form.pdf", "filled_flat.pdf",
    fields={"Name": "Jane Doe"},
    flatten=True,
)

Redaction

Redact text

result = exis_pdfeditor.redact(
    "document.pdf", "redacted.pdf",
    redactions=[
        {"text": "John Doe", "replaceWith": "[NAME REDACTED]"},
        {"text": r"\d{3}-\d{2}-\d{4}", "isRegex": True, "replaceWith": "[SSN]"},
    ],
)
print(f"{result.redactionsApplied} redactions applied")

Redact a specific area on a page

result = exis_pdfeditor.redact(
    "document.pdf", "redacted.pdf",
    redactions=[
        {
            "area": {"x": 100, "y": 700, "width": 200, "height": 20},
            "pageNumber": 1,
        },
    ],
)

        {"area": {"x": 50, "y": 50, "width": 500, "height": 30}, "pageNumber": 2},
    ],
)

Watermark

Basic diagonal watermark

result = exis_pdfeditor.watermark("input.pdf", "watermarked.pdf", "DRAFT")
print(f"Watermarked {result.pagesWatermarked} of {result.totalPages} pages")

All watermark options

result = exis_pdfeditor.watermark(
    "input.pdf", "watermarked.pdf",
    "CONFIDENTIAL",
    position="across",          # top, bottom, center, across
    font_size=72,
    text_color={"r": 1, "g": 0, "b": 0},
    opacity=0.15,
    page_range=[1, 2],
)

Stamp (PDF overlay / underlay)

Overlay a letterhead on top

result = exis_pdfeditor.stamp(
    "document.pdf", "stamped.pdf",
    "letterhead.pdf",
    mode="overlay",
)
print(f"Stamped {result.pagesStamped} pages")

Underlay a background behind content

result = exis_pdfeditor.stamp(
    "document.pdf", "stamped.pdf",
    "background.pdf",
    mode="underlay",
    opacity=0.5,
    page_range=[1],
)

Bates stamping

Sequential page numbering for legal production and discovery workflows. Each page receives a zero-padded identifier (e.g. ABC000001, ABC000002) rendered in a chosen corner of the visual page. Placement is relative to the page's /Rotate orientation, so mixed-rotation documents render consistently. An XMP audit block recording the range, digit width, and prefix/suffix is written to the document catalog by default.

Defaults (number starts at 1, 6 digits, bottom-right corner)

result = exis_pdfeditor.bates_stamp("input.pdf", "stamped.pdf")
print(f"Stamped pages {result.firstNumber}-{result.lastNumber}")
print(f"Digits used: {result.digitsUsed}")

Prefix, custom position, color, confidentiality label

result = exis_pdfeditor.bates_stamp(
    "input.pdf", "stamped.pdf",
    prefix="ABC",
    start_number=1,
    digits=6,                                 # -> "ABC000001"
    position="bottom_right",                  # top_left, top_center, top_right,
                                              # bottom_left, bottom_center, bottom_right
    font_size=10,
    text_color={"r": 0, "g": 0, "b": 0},
    background_color={"r": 1, "g": 1, "b": 1},  # opaque box behind stamp
    margin_inches=0.5,
    confidentiality_label="CONFIDENTIAL",     # stacked above the Bates number
)

Continuous numbering across a batch

Thread lastNumber + 1 into the next call:

next_n = 1
for path in docs:
    r = exis_pdfeditor.bates_stamp(
        path, path + ".stamped.pdf",
        prefix="ABC", start_number=next_n,
    )
    next_n = r.lastNumber + 1

Skip the cover page (legal convention)

The cover is ABC000001 in the production log even if physically unstamped:

exis_pdfeditor.bates_stamp(
    "input.pdf", "stamped.pdf",
    prefix="ABC",
    skip_first_page=True,
    counter_advances_on_skipped_pages=True,   # default
)

Stamp only selected pages

exis_pdfeditor.bates_stamp(
    "input.pdf", "stamped.pdf",
    page_range=[2, 3, 5],                     # 1-based
)

Signed input

Stamping invalidates signatures — opt in explicitly:

result = exis_pdfeditor.bates_stamp(
    "signed.pdf", "stamped.pdf",
    allow_signed_input=True,                  # result.warnings will record it
)
for w in result.warnings:
    print(f"  warning: {w}")

Suppress the XMP audit block

exis_pdfeditor.bates_stamp(
    "input.pdf", "stamped.pdf",
    write_xmp_metadata=False,
)

All options at a glance

Parameter	Default	Purpose
prefix / suffix	""	Text bracketing the number
start_number	1	First Bates number (for batch continuation)
digits	6	Minimum zero-padded width; auto-expands if needed
position	"bottom_right"	Corner/edge on the visual page
font_size	10.0	Point size (Helvetica)
text_color	black	RGB dict {"r": 0, "g": 0, "b": 0}
background_color	none	Opaque rectangle behind stamp for legibility
margin_inches	0.5	Distance from trimmed page edge
confidentiality_label	none	e.g. "CONFIDENTIAL"
confidentiality_position	same corner	Override to place label elsewhere
confidentiality_font_size	matches font_size	Label point size
page_range	all pages	1-based page numbers to stamp
skip_first_page	False	Skip page 1 (cover sheets)
counter_advances_on_skipped_pages	True	Advance counter on skipped pages
allow_signed_input	False	Stamp PDFs with digital signatures
write_xmp_metadata	True	Write an XMP audit block to the catalog

Result fields: firstNumber, lastNumber, pagesStamped, digitsUsed (equals digits unless auto-expanded), warnings (non-fatal diagnostics: digit expansion, signed-input stamped anyway, etc.).

exis_pdfeditor.insert_blank_pages(
    "input.pdf", "with_blanks.pdf",
    insertions=[

        {"afterPage": 3, "size": "letter"},   # after page 3
    ],
)

Images

Find all images

result = exis_pdfeditor.find_images("document.pdf")
print(f"Found {result.totalImages} images across {result.pagesSearched} pages")

for img in result.images:
    print(f"  Image {img.index}: {img.pixelWidth}x{img.pixelHeight} "
          f"{img.colorSpace} {img.format}")

    reason="Approved",
    location="New York, NY",
    signer_name="John Doe",
)

Sign with a visible signature

exis_pdfeditor.sign(
    "document.pdf", "signed.pdf",
    cert_path="certificate.pfx",
    cert_password="certpass",
    visible=True,
    page=1,
    rect={"x": 50, "y": 50, "width": 200, "height": 60},
    reason="Reviewed and approved",
)

print(f"Signer: {info.signerName}")
print(f"Valid:  {info.isValid}")
print(f"Reason: {info.reason}")
print(f"Date:   {info.signDate}")

# Verify all signatures in a multi-signed document

    print(f"  {sig.signerName}: valid={sig.isValid}")

PDF/A compliance

Validate

result = exis_pdfeditor.pdfa_validate("document.pdf", level="2b")
print(f"Compliant: {result.isCompliant}")

if not result.isCompliant:
    for v in result.violations:
        print(f"  [{v.code}] {v.message} (auto-fixable: {v.canAutoFix})")

Convert to PDF/A

exis_pdfeditor.pdfa_convert("document.pdf", "archive.pdf", level="2b")

Supported levels: 1b, 2b, 2u, 3b, 3u.

Diagnostic structure dump

When a PDF fails to process and you can't share the file, dump_structure() produces a self-contained report you can paste into a bug report. It walks every object in the file, tallies filter chains and font subtypes, lists encryption details, and records any streams that fail to decode — without needing the original file. No license required.

Human-readable report

dump = exis_pdfeditor.dump_structure("problem.pdf")

# The dump has a built-in text report — just print it
# (or paste it into a support email / bug report)
print(dump)

Individual fields

dump = exis_pdfeditor.dump_structure("problem.pdf")

print(f"PDF version:    {dump.version}")
print(f"Pages:          {dump.pageCount}")
print(f"Total objects:  {dump.totalObjects}")
print(f"Stream objects: {dump.streamObjectCount}")
print(f"Xref entries:   {dump.xrefEntryCount}")
print(f"Xref streams:   {dump.usesXrefStreams}")
print(f"Producer:       {dump.producer}")
print(f"Creator:        {dump.creator}")

# Encryption details
print(f"Encrypted:      {dump.isEncrypted}")
if dump.isEncrypted:
    print(f"  Version:      {dump.encryptionVersion}")
    print(f"  Revision:     {dump.encryptionRevision}")
    print(f"  Key length:   {dump.encryptionKeyLengthBits} bits")

# Catalog flags
print(f"AcroForm:       {dump.hasAcroForm}")
print(f"Signed:         {dump.hasDigitalSignature}")
print(f"Embedded files: {dump.hasEmbeddedFiles}")

# Filter chains — which compression methods are used and how often
for chain in dump.filterChains:
    print(f"  {chain}: {dump.filterChains[chain]} streams")

# Font subtypes
for subtype in dump.fontSubtypes:
    print(f"  /{subtype}: {dump.fontSubtypes[subtype]}")

# Streams that failed to decode (capped at 50)
for bad in dump.unsupportedStreams:
    print(f"  obj {bad.objectNumber} [{bad.filterChain}]: {bad.error}")

# Free-form notes about parse anomalies
for note in dump.notes:
    print(f"  {note}")
