Find and replace blank pages in a PDF
Automatically Scan every page for blank or near-blank content, review what Folia found, and remove the ones you don't need — all inside your browser.
Three steps, no learning curve
No accounts, no installs — everything happens in the tab you already have open.
Add your file
Drag a file into the box above, or click to browse. It loads instantly — nothing is uploaded anywhere.
Set your options
Choose a sensitivity threshold, then click Analyze — Folia scans every page and flags the blank ones.
Download the result
Your finished file is ready in seconds, generated locally and yours to save or share.
Catch blank pages a skim-read would miss
Scanners leave blank backs, batch uploads pick up stray cover sheets, and long reports quietly collect empty pages between sections. Folia renders every page in your PDF and measures how much of it is actually ink versus white space, so you don't have to click through the whole document to find them.
Adjust the sensitivity if your scans are noisy or slightly off-white, then review the flagged pages before you commit — nothing is removed until you say so.
- Automatic page-by-page scan with an adjustable sensitivity threshold
- Built-in controls for scanner noise and off-white or skewed pages
- Review every flagged page as a thumbnail before removing anything
- Handles documents of any length
Frequently asked questions
How does Folia detect blank pages?
Every page is rendered in your browser and scanned pixel by pixel. Pages with less non-white content than your chosen threshold are flagged as blank.
Will scanned or slightly skewed pages get flagged by mistake?
The ignore-border and white-threshold controls let you compensate for scanner noise and skewed edges before anything is flagged.
Can I keep a flagged page instead of removing it?
Yes — uncheck any flagged page before downloading, or remove pages individually instead of using the bulk option.
