What Extract Images does
PDFGrover's Extract Images tool pulls every embedded image out of a PDF and saves them as separate files — the original embedded image data, not a re-render of the page. A PNG embedded in the source comes out a PNG; a JPG stays a JPG, at its original resolution.
When to extract images from a PDF
- Recovering photos from a PDF assembled from camera shots — get the full-resolution originals back.
- Pulling diagrams or charts out of a report to reuse in slides.
- Extracting product shots from a catalogue PDF.
- Auditing a document — review every distinct image it contains.
How to extract images
- Upload a PDF — it stays on your device.
- Scan — the tool walks every page and pulls the raw embedded image data; thumbnails preview what was found.
- Download — one image downloads directly; multiple arrive as a
.zipnamedpage-N-image-K.extin source order.
Why this isn't "PDF to JPG"
| Need | Use |
|---|---|
| The raw embedded images at source quality | Extract Images (this tool) |
| Each page rendered as a JPG | PDF to JPG |
| Each page rendered as a PNG | PDF to PNG |
Extract Images returns the photos/scans/diagrams embedded in the PDF at their original resolution. PDF to JPG/PNG returns snapshots of each whole page as seen on screen.
Good to know
- Source resolution preserved — a 300 DPI embedded photo comes out at 300 DPI, not a 72 DPI screen-render. That's what makes this useful for archival or print-ready work.
- Automatic de-duplication — PDFs reuse the same image object (a header logo on every page); you get one copy, not 200 identical ones.
- Vector content is excluded — lines, charts, and shapes drawn with PDF path commands aren't raster images. Use PDF to PNG to capture vector diagrams as images.
- Format preserved — JPG→JPG, PNG→PNG; unusual formats (e.g. JPEG2000 from some scanners) are saved as PNG for portability.
Limits & privacy
- One file per session; no hard size cap (bounded by browser memory).
- Runs entirely in your browser — nothing is uploaded, stored, or logged. No sign-up, no watermark.
Troubleshooting
- No images found — the "images" may be vector drawings, not raster; render pages with PDF to PNG instead.
- Fewer images than expected — repeated logos are de-duplicated to a single copy by design.
- Image looks low-res — that's the resolution it was embedded at; extraction can't add detail that isn't in the file.
