An outdated screenshot in a product manual, the wrong scanned page glued into a contract, a photo you want to swap out on a resume — these all call for actually replacing an image that already exists in the PDF, not just layering a new one on top. Here's how.

Steps

  1. Open LocalPDF and load your PDF file.
  2. Click the "Edit Original Content" tool in the toolbar.
  3. Move your mouse over an image on the page — a selectable outline appears around it.
  4. Click the image to select it; an action button appears above it — choose "Replace Image."
  5. Pick a new image from the file picker (PNG / JPG / WebP all work) — it automatically fills the same position and size as the original.
  6. If needed, drag to fine-tune the new image's position or size.
  7. Click "Download" to save the result.

Replace vs. delete-and-reinsert: what's the difference

If you just delete the original image and drop in a new one with the Image tool, you'll need to manually align position and size yourself. "Replace Image" instead carries over the original image's position and aspect-ratio frame, and the new image automatically fits into it — faster, and much less likely to end up misaligned.

What if a page has several images

If a page has multiple small images (like a product manual's image grid), click on the specific one you want to replace first, confirm the selection outline hugs that exact image's boundary, then click "Replace Image" — this avoids accidentally selecting a neighboring image.

Try selecting an image and see what the "Replace Image" button looks like.
