An outdated screenshot in a product manual, the wrong scanned page glued into a contract, a photo you want to swap out on a resume — these all call for actually replacing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
- Open LocalPDF and load your PDF file.
- Click the "Edit Original Content" tool in the toolbar.
- Move your mouse over an image on the page — a selectable outline appears around it.
- Click the image to select it; an action button appears above it — choose "Replace Image."
- Pick a new image from the file picker (PNG / JPG / WebP all work) — it automatically fills the same position and size as the original.
- If needed, drag to fine-tune the new image's position or size.
- 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.
