How to add a company logo to the header of every pdf page
- Step 1Place the logo on a full-page transparent PDF — Create a page matching the document size (A4/Letter, correct orientation), position your logo in the header area at the top of the page, leave everything else transparent, and export a single-page PDF. A bare logo graphic alone will centre mid-page, so the full-page approach is what puts it in the header.
- Step 2Convert a PNG/JPEG logo if needed — The stamp must be a PDF. If your logo is a PNG or JPEG, run it through image-to-pdf — ideally onto a full document-sized page with the logo at the top — before stamping.
- Step 3
- Step 4Add the document, then the logo PDF — The first PDF is the base, the second is the logo overlay. Drop the document first, then the logo PDF, and check the order in the queue.
- Step 5Process and review the header — Click Process 2 files. Confirm the logo appears in the header and reads clearly at 50% opacity — if it's too faint, make the logo artwork bolder and re-stamp.
- Step 6Download the branded PDF — Save
yourdoc.stamp.pdf. Compress with lossless compression if embedding the logo on every page inflated the size.
Why a bare logo doesn't land in the header
The tool centres and fit-scales the stamp. Position comes from how you lay out the stamp PDF, not from the tool.
| Stamp you upload | Where the logo ends up | Verdict |
|---|---|---|
| Small logo-only PDF (e.g. 200×80 pt) | Centred in the middle of every page | Wrong for a header |
| Full-page PDF, logo at top, rest transparent | Logo appears in the header (because the full page is centred) | Correct |
| Logo PNG/JPEG | Rejected — not a PDF | Convert with image-to-pdf first |
| Full-page PDF with a white (opaque) background | Logo in header, but the page body is half-greyed | Make the body transparent |
Logo-PDF design guide
Design choices that determine the final header appearance — none can be changed in the tool afterwards.
| Property | Recommended | Reason |
|---|---|---|
| Page size | Match the document (e.g. A4 595×842 pt) | A size mismatch fit-scales and re-centres, shifting the logo off the top edge |
| Logo position on the page | Top centre or top right | Centring the full page reproduces this position on the document |
| Background | Transparent | 50% opacity over an opaque background veils the document body |
| Logo colour strength | Solid / bold | It paints at 50%, so faint logos disappear |
| Logo resolution (if vector unavailable) | 300 DPI at display size, embedded via image-to-pdf | Keeps the logo crisp on screen and in print |

Cookbook
Logo-header recipes built around the centred, fit-to-page, 50%-opacity, every-page overlay.
Top-right logo on a white-label report
A vendor sends a plain report; you add your logo to the top-right of every page.
logo PDF: brand-header.pdf (full A4 page, logo at top-right, rest transparent) base: vendor-report.pdf (24 pages) Process 2 files → full page centred → logo appears top-right on all 24 pages Output: vendor-report.stamp.pdf
From a PNG logo to a header stamp
Marketing's logo is a transparent PNG. Build the header PDF, then stamp.
image-to-pdf: logo.png (placed top-centre of an A4 page) → brand-header.pdf pdf-stamp: base: export.pdf stamp: brand-header.pdf → export.stamp.pdf (logo top-centre, all pages)
The logo ended up in the middle of the page
A logo-only PDF was used, so it centred mid-page instead of the header.
Wrong: logo-only.pdf (200x80 pt)
→ centred → mid-page
Right: redo as a full-page A4 PDF with the logo
drawn at the top, rest transparent
→ centred full page → logo in the headerBody text greyed out
The header PDF had an opaque white background.
Symptom: document text washed out under the logo page
Cause: 50% opacity + opaque white page background
Fix: export the header PDF with a transparent
background — only the logo paints.Logo prints too pale
A light grey logo nearly vanishes at 50% opacity in print.
Cause: fixed 50% opacity halves the logo's strength
Fix: use the full-colour / solid version of the logo
in the stamp PDF so it reads at 50%.Edge cases and what actually happens
Logo lands in the page centre, not the header
By designThe tool centres the stamp. A logo-only PDF therefore appears in the middle of each page. To put it in the header, draw the logo at the top of a full-page transparent stamp PDF; centring the full page places the logo at the top.
Logo is a PNG or JPEG
invalid inputOnly PDFs are accepted as the stamp. Convert the logo image with image-to-pdf into a single-page (ideally full-page) PDF first.
Logo PDF background is opaque white
design issueAt 50% opacity an opaque background half-covers the document body. Re-export the logo PDF with a transparent background so only the logo paints.
Existing header text under the logo
overlapThe logo is drawn on top of whatever is already on the page, including existing header text. Position the logo to one side in your stamp PDF, or clear space first with pdf-crop/page tools, so they don't collide.
Logo prints too light
ExpectedThe fixed 50% opacity also affects print. A pale logo washes out. Use a solid, full-strength version of the logo in the stamp PDF so the half-opacity draw is still legible.
Only one file uploaded
errorTwo PDFs are required. With fewer than two the tool refuses to run and the Process button stays disabled. Add the logo PDF as the second file.
Multi-page logo PDF
first page usedOnly the first page of the stamp PDF is used and repeated on every page; later pages are ignored. Keep the logo stamp a single page.
Logo and document differ in size
fit + centreA mismatched stamp size is fit-scaled and re-centred, so the logo drifts from the exact top edge. Build the logo PDF at the document's page size and orientation.
Output much larger than input
ExpectedEmbedding a logo page on every page increases file size. Compress losslessly before distributing if needed.

Frequently asked questions
Can I put the logo in the header area only?
Not with a position setting — the tool always centres the stamp. The way to land a logo in the header is to design a full-page transparent PDF with the logo at the top of the page; when the tool centres that full page over your document, the logo appears in the header. A bare logo-only PDF would centre in the middle instead.
My logo is a PNG — can I use it directly?
No. The stamp must be a PDF. Convert your PNG (or JPEG) with image-to-pdf, preferably placing the logo at the top of a document-sized page, then use that PDF as the stamp.
Can I resize the logo in the tool?
No — there's no size control. The stamp is fit-scaled to the page (and never enlarged). Control the logo's apparent size by how large you draw it within the full-page stamp PDF.
Why does the logo look semi-transparent?
The overlay is drawn at a fixed 50% opacity and there's no setting to change it. Use a solid, full-strength version of the logo in the stamp PDF so it remains clearly visible at half opacity. If you need adjustable opacity for a text mark, the watermark tool offers an opacity slider for text.
Will the logo overlap existing header content?
It might — the logo is drawn on top of whatever is already there. If the document already has a header, position the logo to one side within your stamp PDF, or clear space first using the page/crop tools, so they don't collide.
Does the logo go on every page?
Yes — the overlay is applied to every page, which is exactly what you want for a brand header. There is no per-page option to stamp only some pages.
What resolution should the logo be?
For a raster logo, aim for about 300 DPI at the size it will display, embedded via image-to-pdf. A vector logo placed in a PDF stays crisp at any size. Either way, build it into the stamp PDF at the document's page dimensions.
Does the order of files matter?
Yes — the first PDF added is the base document, the second is the logo overlay. Add the document first, then the logo PDF, and confirm the order in the file queue before processing.
Is anything uploaded to a server?
No. Both PDFs are processed entirely in your browser. White-label documents and your brand assets never leave your device; only an anonymous usage counter is recorded when you're signed in.
How large a document can I brand?
Free tier allows 2 MB and 50 pages per PDF; Pro raises this to 50 MB and 500 pages. The limits apply to the document and the logo PDF separately.
The branded file got bigger — how do I shrink it?
Embedding the logo on every page adds content, so the file grows. Run the output through lossless compression to keep text selectable while reducing size; avoid lossy compression, which would rasterise your logo and text.
Can I use different logos on different pages?
Not in a single pass — one stamp is applied to all pages. To vary it, split the document into page groups, stamp each group with its own logo PDF, then reassemble with pdf-merge.
