Split PDF by Blank Page.

The tool checks rendered page pixels, selectable text and form fields. A page is selected only when it has no selectable text, no form widget and no more dark pixels than the chosen sensitivity allows.

Click Find blank pages to review first, or click Split PDF to detect and export in one step. Detected thumbnails are tinted yellow and the active separator is labelled in the preview.

Strict is the default, matching Remove Blank Pages, and works best for clean digital files. Light noise allows a few scan specks. Scan noise accepts more marks and can find otherwise empty backs in noisier batches.

Higher tolerance can classify faint content as blank. Review pale handwriting, lightly printed forms and intentional white pages before splitting.

Remove blank separators is selected by default. Clear it to keep every page, then choose whether each blank marker starts the next section or ends the previous section.

Consecutive blank pages form one separator. Keeping them attaches the whole run to the chosen neighboring section, and leading or trailing blanks stay with the nearest section. If every page appears blank, the original file is preserved unchanged inside the ZIP.

Click a yellow thumbnail to inspect a detected separator. The numbered part cards show the page span for each output and jump directly to its first page.

If no blank page is found, the result is one PDF containing the complete document. Change sensitivity only when the visual review shows missed or incorrect markers.

Text, vectors and original images are copied rather than rasterized. The ZIP contains numbered PDFs in document order, with a 500 MB combined output safeguard.

Your file stays in the browser. Open one unlocked PDF up to 100 MB and 200 pages. Scan time depends on the number and size of pages and the speed of your device.
