Page Management
10Merge PDF
Merge several files, reorder them by drag and drop. Handles PDF and common image formats, with a compatibility mode for tricky invoice PDFs.
Alternate & Mix
Interleave A-B-C-…: take one page from each file in turn and merge them together.
Split PDF
Five split modes: by page range, fixed page count, single page, odd/even, or multiple groups.
Split by Bookmarks
Reads the outline, tick the chapters you need, and merges all selected chapters into one PDF.
Explode by Bookmarks
Splits every bookmark into its own file, with custom naming rules, packed as a ZIP.
Organize Pages
Drag thumbnails to reorder, tick pages to remove, insert blank pages, then export.
Reverse Pages
Reverse the page order in one click while keeping the original quality and metadata.
Add Blank Page
Automatically appends one blank page when the PDF has an odd number of pages.
Remove Pages
Remove pages by number, or simply click the thumbnails to pick them.
Remove Blank Pages
Checks whether a page contains text (pages with text are always kept), then flags blank pages by their ratio of non-white pixels.
Page Adjustments
10Rotate Pages (Batch)
Rotate an entire page range by 90° or 180° at once.
Rotate Pages (Each Page)
Choose the rotation angle for each page individually.
N-up Layout
2-up, 4-up or 9-up: place several pages onto a single sheet.
Booklet Imposition
Reorder pages for saddle-stitch binding, so double-sided prints fold straight into a booklet.
Split Booklet Scan
Cut a scanned saddle-stitch booklet into pages and put them back in the right order.
Normalize Page Size
Normalize every page to one paper size: text pages scale as vectors, image pages are rasterized.
Split Facing Pages
Cut scanned spreads down the middle; drag the red line to adjust, splitting left/right, top/bottom, or not at all.
Deskew Scans
Straighten scanned pages automatically or by hand, using automatic detection with projection histograms.
Crop White Margins
Automatically trims the white margins on all four sides; drag the blue dashed box to fine-tune.
Create Blank PDF
Create a pure white PDF with a custom page size and page count.
Format & Images
10PDF to Word
Extracts text, tables and images into an editable Word document (.docx), keeping font size, line spacing, colour, bold/italic and the general layout.
PDF to Excel
Turns tables in a PDF back into an editable .xlsx with real merged cells, borders and number formats; several files can be processed in one batch.
PDF to Image
Renders every page as a high-resolution image — PNG or JPEG — for download one by one or as a ZIP.
Image to PDF
Combines several images into one A4 PDF, with adjustable orientation, margins and centering.
Flatten PDF
Turns text, forms, comments and layers into images, producing a final, non-editable document.
Extract Images
Finds every embedded image and previews them in a thumbnail grid for single or bulk (ZIP) download.
Page Filters
Brightness/contrast, sharpen, grayscale, black & white and invert — stack several filters together.
Blueprint Style
Converts every page to a blue-background, white-line blueprint style, with adjustable background depth and line brightness.
Simulate Scan
Re-renders each page as an image and rebuilds the PDF for a scanned look, keeping bookmarks and document info.
Clean Up Scans
Automatically erases scan noise, specks and patches of grey background while keeping text, tables and lines intact.

8Add Page Numbers
Custom page-number format, font and position, with mirrored placement on odd and even pages.
