Split, Extract, Rotate & Delete PDF Pages

Work with a PDF page by page. See every page as a thumbnail, pull out just the pages you need, split into files every N pages, delete unwanted pages, or straighten sideways scans. The file is processed only in this browser — nothing is uploaded — and text and image quality are preserved.

🔒 Files are processed only inside your browser on this device and are never uploaded. The site records an anonymous "tool used once" count — never file names or contents.

How to use

Drop one PDF into the box above (or click to choose). Every page appears as a thumbnail.
Tap pages to select them. Click one page and Shift-click another to select the span, or type ranges like “1-3, 5, 8-” and press “Select range”.
To rotate, select pages and press Left 90° / Right 90°. Rotation shows in the preview and applies to every output mode.
Choose the output — extract selected, split into files (every N pages or per range, as a ZIP), delete selected, or save the whole file with rotations.
Press “Save & download” and the result PDF (or ZIP) downloads immediately. Your original file is never modified.

How to write page ranges

Type page numbers and ranges separated by commas. “5” is page 5; “1-3” is pages 1–3; “8-” is page 8 to the end; “-3” is the first three pages. Spaces are fine. In a 30-page document, “1, 4-6, 25-” selects pages 1, 4, 5, 6 and 25–30.

With “One file per range”, each comma-separated piece becomes its own PDF: “1-3, 4-10, 11-” gives three files in one ZIP. Setting “Every N pages” to 1 bursts the document into single-page PDFs.

When to split and when to extract

The most common reason is sending only what's needed: five installation pages out of a 100-page manual, one month of a bank statement, or your own pages from a batch scan. Select them and use “Extract selected”.

If an upload portal limits file size (say 10 MB per file), “Every N pages” splits a large PDF into chunks. If only a few pages must go — blanks, ads, pages with personal data — select them and use “Delete selected”.

Scanned PDFs often contain sideways or upside-down pages. Rotate just those and “Save with rotation” so readers don't have to turn their screens.

Why quality and text are preserved

Each PDF page is a content stream plus the font and image objects it uses. This tool copies those objects into the new PDF unchanged, so text stays searchable and images keep their original resolution — unlike tools that screenshot pages into a new PDF.

Rotation changes the page's /Rotate value (0/90/180/270) rather than redrawing anything, so it's lossless. Note that when pages share fonts or images, splitting puts a copy of those shared resources in each output, so the parts can add up to more than the original.

Why nothing is uploaded

PDFs people split often contain ID scans, payslips, contracts or medical records. This tool never sends the file anywhere: JavaScript (pdf-lib and pdf.js) processes it on your device, and thumbnails are drawn by your browser. Results are saved straight to your device and disappear from memory when you close the tab.

Privacy

The PDF you choose is read and edited only in this browser's memory and is never stored. Closing the tab clears it. The site records only anonymous counts such as “tool used once” and which output mode was used — never file names or contents. Ads on this page have no access to your files.

FAQ

Is my original PDF modified?

No. The original is only read; results are downloaded as new files.

Can I reorder pages while extracting?

Extraction keeps the original order. To reorder, open the extracted file in Merge PDF, click “Show all pages”, move pages by dragging or with ◀ ▶, then save.

What about password-protected PDFs?

PDFs with an open password or permission restrictions are encrypted and can't be edited. If viewing/printing is allowed, open it in Chrome and use Print → Save as PDF to make an unrestricted copy — only for documents you have the right to use.

How many pages can it handle?

There's no fixed limit; thumbnails are drawn lazily as they scroll into view, so documents with hundreds of pages open fine. Files of several hundred MB may be slow or fail depending on device memory.

Are bookmarks, links and form fields kept?

Page content is identical, but document-level bookmarks, fillable form fields and internal links may be dropped from the output.

Will rotated pages look rotated in other viewers?

Yes. Rotation is stored as the standard PDF page rotation value, so Acrobat, browsers and mobile viewers all show the same orientation.
