How to batch-stamp PDFs with your company logo

Stamping modes and when to use each

Step by step — batch-stamping the company logo

1. Prepare a canonical logo file. Transparent-background PNG (or vector), versioned (logo-v3.png), one per brand.
2. Decide a single house style for placement. Corner stamp, header band, cover-only, watermark — and document it so the team is consistent.
3. Test on a sample PDF. Use Add Image to PDF or Add Watermark on a representative document; adjust size, opacity, coordinates.
4. Lock the placement parameters. Page coordinates, size, opacity, every-page vs. cover-only — pin them so the batch run is deterministic.
5. Run the batch. Apply the same placement across the folder; output a stamped copy of each input, keep the originals.
6. Sanity-check three files. First, middle, last — scroll fully, confirm the stamp appears in the same place on every page.
7. Compress for delivery if needed. Compress keeps email/portal sizes manageable without re-stamping artefacts.
8. Flatten on issue where stamps + signatures combine. Use Flatten so the issued document cannot be edited to remove the stamp.

Pitfalls that ruin a batch stamp

• Logo on a white rectangle. The lozenge sits visibly on top — export with transparency.
• Low-resolution logo image. Blurry on print; export at 300 DPI minimum or use vector.
• Placement set relative to content. Lands in different spots on differently-laid-out pages — pin to page coordinates.
• No sanity check across the batch. One bad file ships with the rest and undermines the brand.
• Mixing logo versions across the same period. Use one canonical file, versioned, deliberately rotated.
• Watermark too transparent to see. DRAFT becomes invisible by page 5 — adjust opacity until the mark is unambiguous.
• Stamping on an editable layer. If the issued document should not lose the stamp, flatten.
• Uploading client-confidential PDFs to a cloud tool without checking whether they leave the machine.

FAQ

How should I prepare the logo image for batch stamping?

A logo for repeated overlay on PDFs needs to render crisply at the size it will be placed and to sit on the page without obscuring underlying content. Export the logo as PNG with a transparent background, at a resolution that is crisp at the printed (not just on-screen) size — 300 DPI minimum is a common practical baseline — and prefer the vector original where the tool will accept it (some workflows accept SVG, which scales without quality loss). Keep one canonical logo file per brand and version it (logo-v3.png) so every stamped PDF in the same period uses the identical mark. Avoid embedding the logo on a white rectangle — that lozenge of white will sit visibly on top of the underlying page content and look unprofessional.

Where should the logo go on the page?

Decide on a single house style and apply it consistently across every PDF you stamp, because the inconsistency is what looks unprofessional, not the placement choice itself. Typical placements: a small corner stamp (top-right of every page; usually small enough that it does not interfere with content) for general branding; a header band that runs across the top with the logo on one side and the document title on the other; a centre watermark (large, semi-transparent, behind the text) for status flags like DRAFT or CONFIDENTIAL; a cover-page-only larger logo as title-page branding. Whichever you choose, pin the placement to page coordinates (not "relative to content") so the logo lands in the same spot on every page in the batch.

Watermark vs. stamp — which do I want?

A stamp is an opaque or near-opaque mark placed on top of the page content, typically smaller and in a corner or header. A watermark is a semi-transparent mark, typically larger and centred, sitting underneath or visibly behind the page content to communicate status (DRAFT, CONFIDENTIAL, SAMPLE) without obscuring the underlying text. For branding (the company logo on a report), the stamp pattern is usually what you want — sized so it does not overlap content. For status communication (DRAFT, CONFIDENTIAL), the watermark pattern is what you want — semi-transparent, behind the text, hard to miss. Some workflows combine both (corner-stamp logo on every page plus a centre DRAFT watermark on draft versions).

How do I batch-stamp many PDFs in one operation?

There are two practical patterns. (1) Same-logo-many-files: prepare the logo once, prepare the placement (corner, page coordinates, size, opacity), and run a batch operation that applies the same stamp to every input PDF in a folder; the output is a stamped copy of each input. (2) Different-logo-per-file: build a small mapping (filename → which logo) and either run a script per file or use a tool that takes the mapping as input. The first pattern is by far the most common — one company, one logo, many documents in the same period. As a PDF craft, prepare the logo and the placement once, verify on a small sample, then run the batch and verify the output.

Should the stamp be on every page, or just specific pages?

It depends on the document type. For branded report-style documents, every-page stamping is common because the document may be printed or excerpted, and you want the brand visible on any sheet that travels alone. For document types with a designated cover page (proposals, large reports), a larger cover-page-only logo plus a smaller every-page header logo is a typical layout. For status watermarks (DRAFT, CONFIDENTIAL), every-page is the rule — a single DRAFT watermark on page 1 of a 50-page document is essentially invisible by page 30. Decide once per document type and document the rule in your house style so the team is consistent.

How do I verify the stamp landed correctly across the whole batch?

After running the batch, open three sanity-check files: the first, a middle file (a random one from the run), and the last. For each, scroll the full document and confirm the stamp appears on every page it should, in the same place, at the same opacity and size, and that it does not overlap critical content anywhere. Compare two of the stamped files side by side to confirm consistency. If anything looks off, fix the placement parameters and re-run; do not ship a batch where the stamp landed inconsistently. For high-volume batches, a small automated check that opens each output and verifies a stamp pixel is present at the expected coordinate can be worth building.

Is it safe to batch-stamp PDFs in an online tool?

Branded PDFs often contain client-confidential or commercially sensitive content, so prefer a tool that processes files locally. ScoutMyTool batch-stamps logos and watermarks entirely in your browser tab, so the source files never leave your machine. For confidential or contractually-restricted batches, confirm the tool does not upload before using it.
