# Delete blank pages from a scanned PDF

> Remove blank pages from a scanned PDF in your browser. See thumbnails, delete, reorder, or rotate. No upload.

Thumbnails stay on this device

ADF scanners love to keep the empty back of a sheet. This page draws a thumbnail of every page in your browser so you can delete blanks, fix order, or rotate a stray landscape table before you save. The preview is pixels on your machine, not an upload.

Free. There is no paid tier. No account. They stay on your computer. Nothing is uploaded.

## When to use this

Use this after a duplex scan that kept empty backs, or a packet with a leftover blank sheet in the middle. Thumbnails render in this browser so you can see the blanks instead of guessing page numbers.

Delete is a new-file operation: you save a copy without those pages. The original on disk stays put until you replace it yourself.

If you already know the range to keep, [Extract pages](https://lovethispdf.com/extract-pdf-pages.md) is faster than clicking thumbnails. Come here when you need to look.

## How to do it

1. Drop the scanned PDF. Thumbnails draw locally, one page at a time.
2. Delete the blank sheets. Drag or use arrows if a page is in the wrong place.
3. Rotate a stray landscape page in the grid if needed.
4. Save PDF and download the cleaned copy.

## Tips

- Almost-white scans with a speck of dust still look “not blank.” Zoom the thumb before you keep a mystery page.
- Very long documents render thumbs sequentially so the tab does not freeze.
- Number pages after blanks are gone, or the folios will skip.

## Questions

### Does this auto-detect blank pages?

No. You see thumbnails and delete the empty ones. Automatic blank detection would miss faint scans and keep noisy ones.

### Are the page thumbnails uploaded?

No. PDF.js draws small previews in this browser. They are never sent to LoveThisPDF.

### Will delete change the file on disk immediately?

No. You download a new PDF. Replace the original yourself if that is what you want.
