How to use Extract Images
- Select the PDF.
- Click “Extract images”.
- Download a ZIP of PNG files (named by page).
Original resolution
bopdf reads the image objects stored inside the PDF instead of taking screenshots, so you get each picture at the resolution it was embedded. Tiny images (under 16 px) are skipped and repeated images are saved once. To save whole pages as pictures instead, use PDF to JPG.
🔒 Your files never leave your device
bopdf processes your documents locally with JavaScript (pdf-lib and Mozilla pdf.js) inside your browser tab. Your PDF is never uploaded, stored or seen by us — you can even disconnect from the internet after the page loads and the tool keeps working. When you close the tab, everything is gone.
Frequently asked questions
Why is an image missing?
Vector drawings and charts are not images; use PDF to JPG to capture them.
What format are images saved in?
PNG, which is lossless.
Are my files uploaded to a server?
No. Everything happens in your browser on your own device. Files are never sent over the internet, which makes bopdf suitable for confidential documents.
Is there a file size limit?
There is no fixed limit, but very large files (hundreds of MB) depend on your device memory. On phones, files up to about 100 MB usually work well.
