FAQs

Frequently Asked Questions

Are my PDFs uploaded?

No. All processing happens locally in your browser for privacy. Your PDFs never leave your device.

Can I merge encrypted PDFs?

Only if you provide the password (prompted when detected). For best results, unlock encrypted PDFs before merging.

How do I select pages to split?

Use ranges like `1-3,6,9-` to select specific pages, or click thumbnails to visually select pages. Ranges can include individual pages (5), ranges (1-3), or open-ended ranges (8- for pages 8 to end).

What are the size limits?

Per file up to 100 MB; total up to 300 MB; up to 1000 pages combined. Larger files may take longer to process.

Will metadata be preserved?

Yes, if you enable 'Keep metadata' (defaults to first file's metadata when merging). You can preserve titles, authors, subjects, and other document properties.

Does rotation change the actual page orientation?

Yes, rotation is applied to page content before export. The rotated orientation becomes permanent in the output PDF.

Can I undo operations?

Currently, you can remove files and reselect pages. Full undo/redo functionality is planned for a future update.

What browsers are supported?

Modern browsers with JavaScript enabled (Chrome, Firefox, Safari, Edge). The tool uses client-side processing, so it works offline after initial load.

Drop three PDFs into the tool, drag the thumbnails into the right order, and download one combined file. If pages came out sideways or a contract has blank sheets in the middle, you can rotate, delete, or extract specific ranges before you hit export—all without uploading anything to a remote server.

The 60-Second Fix for Messy Page Order

Scanners rarely care about page sequence. A 30-page scan can arrive with the cover at the back, odd pages flipped, and a random blank on page 17. Instead of re-scanning, load the file here, drag thumbnails into the right positions, delete the blank, and export. The whole fix takes less time than walking back to the printer.

Page-Range Shortcuts That Save Clicks

Typing 1-3,7,12- in the split field grabs pages one through three, page seven, and everything from twelve onward. The dash after 12 means “to the last page,” so you do not need to know the total count. Use this when a client only needs the signature pages from a long agreement or when you want to pull the appendix out of a report without touching the body.

Fast Steps

Load one or more PDFs—drag them in or use the file picker.
Rearrange thumbnails, rotate any sideways pages, and delete blanks.
To split, type a page range (like 4-9) and export just that slice.
Preview the result, then download. The original files stay untouched.

When Pages Will Not Cooperate

Password-protected files. If a PDF is locked, the browser cannot read its pages. Unlock it first with the original password, then reload.
Very large files (100 MB+). Everything runs in browser memory. On a phone or a low-RAM laptop, the tab may slow down or crash. Split the file into smaller chunks on a desktop first.
Metadata from multiple sources. Merging three PDFs keeps the first file’s metadata (title, author) by default. If that matters for archiving, check the metadata option before exporting.

Try These Next

Need a smaller file after merging? Compress the PDF to cut the size before emailing. Converting a batch of photos first? Turn images or HTML into PDF, then merge here. And if you need to verify nothing shifted during the merge, compare the merged output against the originals.

All processing runs in your browser. No files are uploaded to any server.
