Image Find & Replace
Replace logos and images across an entire PDF library
Scan every embedded image, group by dimensions and format into a visual grid, map old to new, and replace across hundreds of files in one batch run. The bulk-rebrand tool for archives, templates, and marketing collateral.

Why a logo change costs three weeks of manual work
A typical mid-sized organization carries 200 to 2,000 PDFs that contain its logo — templates, brochures, annual reports, customer-facing forms, internal SOPs, certifications, training materials. When the logo changes (rebrand, acquisition, regulatory cert update), every one of those files becomes obsolete on the same day. The standard approach is for someone to open each file in Acrobat, manually delete the old image, paste the new one, fight the layout for ten minutes, save, repeat. Three weeks of work, inconsistent results, drift between what's in the archive and what's been updated.
PDF Batch Editor inverts the problem. Instead of working file-by-file, it works image-by-image: scan every PDF in scope, find every embedded image, group identical images together, and replace one logo across the entire library in a single operation. The tool you point at the new logo file once, and every occurrence in every file gets the new asset.
How the scanner sees the library
Grouping by dimensions and format, displayed as a visual grid
The scan walks every loaded PDF, extracts every embedded image, and groups them by (pixel width, pixel height, storage format). The grouping is what makes the tool tractable. A logo embedded across 500 templates is essentially always the same dimensions and format in every file (that's how the templates were generated), so the 500 occurrences land in one bucket in the grid. A photographic banner that varies file-to-file produces multiple buckets. Forms with embedded UI icons (checkboxes drawn as raster) produce buckets you can ignore.
The grid shows a thumbnail of each bucket, the image's dimensions and format, and a count of how many files and pages contain it. Buckets are sortable by occurrence count (most occurrences first — the logo you actually want to replace is at the top), or by dimensions, or filtered by format. For a 500-file library, you typically end up looking at five to twenty unique image buckets total — the rest are dimensions-only matches that the grouping consolidated.
Different sizes of the same logo (large for covers, small for footers) appear as separate buckets — one per size. That is the right behavior: you usually want a high-resolution version of the new logo for the cover and a smaller version for the footer.
Replacement mechanics
What happens when you point at a new file
On-page geometry preserved
The replacement is drawn at the same on-page rectangle as the original. Page layout doesn't shift; text wrapping or column flow set against the original's box stays in place. The replacement's source pixel resolution can be higher or lower than the original's — what determines layout is the rectangle, not the codec.
Format and codec
JPEG, PNG, BMP, and TIFF replacement files supported. The app converts and embeds in the correct PDF-compatible format automatically. PNG is recommended for logos with sharp edges or transparency; JPEG is right for photographic content.
Transparency handling
PNG replacement files with an alpha channel are embedded with transparency intact, so the underlying page content shows through wherever the new logo is transparent. JPEG replacements are always opaque (the format has no alpha channel). If the original image had transparency, supply the replacement as PNG.
Multiple replacements per run
Each bucket in the grid can be mapped to its own replacement file. Map old logo to new logo, old certification badge to new badge, old footer device to new footer device — then execute one batch run that applies all the replacements in sequence across every file in scope.
Inventory and inspection
Extract every image to disk before replacing
Before committing to a 500-file replacement, you may want to see exactly which images are in scope. The Extract action walks every loaded PDF and writes each embedded image to a folder as a separate file, named with the source PDF and the image index (e.g. annual-report-2024_image_3.png). The result is a flat folder of every visual asset in the library, ready for inventory, comparison, or hand-off to a brand designer.
Extraction is also useful as an audit step: archive the originals before a batch replacement so the prior version of every visual is recoverable if a stakeholder later wants to verify what changed.
Use Cases
When you need to update images at scale
Corporate Rebrand
Marketing rolls out a new visual identity. 500 PDF templates, brochures, and forms in the archive carry the old logo. Scan them all, point the largest bucket at the new high-res logo, point the small bucket at the footer-sized version, run. Every file updated, layout intact.
Acquisition Integration
Following an acquisition, the acquired company's branding has to be replaced across 1,200 client-facing documents. Map each old asset to its post-acquisition equivalent in one configuration; the replacement runs in minutes, not weeks.
Compliance Badge Refresh
Certification stamps change year-to-year — new ISO badge, updated FDA mark, new SOC 2 seal. Replace the old badge across every product spec sheet, safety document, and quality manual in a single batch run.
Frequently Asked Questions
How does the scanner identify images that should be grouped together?
The scan groups by image dimensions and storage format. Images with the same pixel width, pixel height, and format are bucketed into one entry in the visual grid, with file and page counts shown next to each bucket. This works because a logo embedded across hundreds of templates is virtually always the same size and format in every file — that's how the templates were generated.
What if the same logo exists at different sizes across the library?
Each size shows up as its own entry in the grid. Large logo for cover pages, small logo for footers, mid-size for letterhead — three buckets, three replacements. Map each one to the appropriately-scaled version of the new logo in a single batch run.
Will the replacement match the original image's footprint on the page?
The replacement is drawn at the same on-page geometry as the original. The page layout doesn't shift; any text wrapping or column flow set against the original image's box stays exactly where it was. The replacement's pixel resolution can differ from the original's — what matters for layout is the on-page rectangle, not the source image's pixel count.
What replacement file formats are supported?
Standard raster formats — JPEG, PNG, BMP, TIFF. PNG is recommended for logos and graphics with sharp edges or transparency. JPEG is right for photographic content. The app converts and embeds in the correct PDF-compatible format automatically; you don't have to think about which codec the file ends up in.
How does transparency work?
PNG replacement images with an alpha channel are embedded with their transparency intact, so the underlying page content shows through wherever the new logo is transparent. JPEG replacements are opaque (the format has no alpha channel) — if you need partial transparency, save the source as PNG.
Can I extract the originals to disk before replacing?
Yes. The Extract action writes every embedded image from the loaded PDFs out to a folder as separate files, named with the source PDF and image index. Useful for inventory, archival, or when you need to feed the originals into a logo-comparison workflow before committing to replacement.
