Clean up scanned documents in one click. PdfDocShift detects every blank or near-blank page, shows you exactly which ones will be removed, and lets you tune the sensitivity so faint marks are kept — or also cleared out.

How it works
Detect blanks visually, decide before you download
Scanned documents often pick up the backs of pages, separator sheets, and stray empty pages from double-sided feeding. Manually paging through to find them is slow and error-prone.
PdfDocShift renders every page in your browser, measures how much ink each page contains, and flags anything below the threshold you choose. You see exactly which pages will be removed before clicking download — no surprises.

Pixel-accurate detectionEach page is analysed at the pixel level — works for scanned PDFs, OCR'd PDFs, and born-digital PDFs equally.

Why remove blank pages from a PDF?
Blank pages creep into PDFs in dozens of ways. Duplex scanners pick up the empty back of every single-sided document. Print drivers add a trailing page when a print job ends mid-page. Office mail-merge templates leave a stray empty page when a record has no body. Book and report PDFs include separator pages between chapters that you may not want in a digital version. The cumulative effect is bloated page counts, larger file sizes, slower printing, and a less professional-looking document.
PdfDocShift's remove blank pages PDF tool fixes all of these in seconds. Upload your file, pick a sensitivity preset, review the preview, and download the cleaned result. No installation, no Adobe Acrobat subscription, no command-line tools — just a browser.
How blank detection works
Every PDF page is rendered to a low-resolution greyscale image in your browser using pdf.js. The tool then counts how many pixels are darker than a threshold (240/255) — these are treated as "ink". The total ink ratio is compared against the threshold defined by your chosen sensitivity. Pages below the threshold are flagged as candidates for removal.
Three presets cover the common cases:
Strict (≤ 0.05% ink): only fully empty pages are removed. Safest setting — even a single page number or footer will keep a page.
Normal (≤ 0.5% ink, default): catches pages with stray scan dots, dust marks, or single tiny artefacts. Recommended for most scanned documents.
Aggressive (≤ 2% ink): also removes pages whose only content is a light watermark, a faint page number, or a single header line. Review the preview carefully — real content can be flagged at this level.
Delete empty pages from scanned PDFs
This tool was built primarily for scanned documents, where blank pages are the rule rather than the exception. Because detection is pixel-based and not text-based, it works on scans that have never been OCR'd, scans where OCR returns garbage, and scans with very faded ink. Each page is judged on its visual content alone, so the result matches what a human would intuitively call "blank".
If you'd like the surviving pages to also be searchable, run them through OCR PDF after cleaning. If you want to combine cleaning with a smaller file size, pair this tool with Compress PDF.
Clean scanned PDF without losing quality
Some online tools that delete pages re-render or re-compress the entire PDF — this can degrade image quality and increase file size. PdfDocShift's blank page remover uses pdf-lib under the hood: it copies the surviving pages losslessly from the source PDF into a new document. Vector graphics, embedded fonts, and high-resolution images remain byte-identical to the original. The only thing that changes is the page count.
When should you use Remove Blank Pages vs. Organize PDF?
Use Remove Blank Pages when you simply want every empty or near-empty page automatically detected and deleted — no manual selection. Use Organize PDF when you need to reorder pages, mix pages from multiple PDFs, or remove specific non-blank pages manually. The two tools complement each other and can be used back to back: clean blanks first, then reorder what remains.
Help & FAQ
Remove Blank Pages questions
Everything you need to know about deleting blank pages from a PDF online for free.
Each PDF page is rendered to a low-resolution greyscale image in your browser, then the percentage of dark (ink) pixels is measured. Pages whose ink coverage falls below the sensitivity threshold you choose are flagged as blank. You can review every flagged page in the preview before downloading.
Sensitivity decides how much ink a page is allowed before it is still treated as blank. Strict only removes truly empty pages (≤ 0.05% ink). Normal (default) also catches pages with stray scan dots (≤ 0.5%). Aggressive removes faint watermarks, light page numbers and very light marks too (≤ 2%) — use it carefully because real content can be flagged.
No. Before downloading, you see every page as a thumbnail with the flagged ones clearly marked. You can untick any false positive, or change the sensitivity preset until the selection is right. The PDF is only modified after you click download.
Yes — this tool is designed for scanned documents. It analyses the page image, not the text layer, so it works equally well on scans that have not been OCR'd, OCR'd PDFs, and born-digital PDFs.
No. Surviving pages are copied losslessly by pdf-lib. No re-rendering or re-compression happens — fonts, vector graphics and embedded images stay byte-identical to the source. If you also want to shrink file size, follow up with Compress PDF.
Up to 1,000 pages in a single file, with a maximum file size of 200 MB. Thumbnail rendering runs progressively in the browser so even large documents stay responsive while you work.
All file transfers use 256-bit SSL encryption. Uploaded files are stored in isolated cloud storage and automatically deleted after 2 hours — no exceptions. We never access the content of your files, share them with third parties, or require you to create an account.
Yes. The thumbnail panel adapts to smaller screens — two columns on mobile, three on tablet. Tapping a thumbnail toggles whether it will be removed. For documents with hundreds of pages, a desktop screen is more comfortable since it fits more thumbnails per row.
