Can I reorder pages before merging PDFs?

Yes! After uploading your PDFs, you can drag and drop to reorder the files. You can also rearrange individual pages within each PDF. This gives you complete control over the final document's structure before creating the merged PDF.

Is there a file size limit for merging PDFs?

There are no artificial limits imposed by our servers since all processing happens locally in your browser. The practical limit depends on your device's memory. Most modern devices can handle PDFs totaling hundreds of megabytes. If you encounter performance issues, try merging files in smaller batches.

Are my PDF files uploaded to your servers during merging?

Absolutely not. All PDF merging happens entirely within your browser using client-side JavaScript and PDF manipulation libraries. Your documents never leave your device, ensuring complete privacy and security. This makes it safe to merge sensitive documents like contracts, financial records, and personal files.

Will the quality of my PDFs be affected by merging?

No, the original quality of each PDF is preserved exactly. The merge process combines the files without re-rendering or compressing the content. All text, images, fonts, and formatting remain exactly as in the original files. The resulting merged PDF is a lossless combination of your input files.

Can I add a table of contents to the merged PDF?

Currently, our merger creates a straightforward combined document without automatically generating a table of contents. However, you can create a separate first page (as a PDF) listing the contents, upload it first, then merge your other documents after it. Advanced TOC generation is planned for future updates.

What should I do if the merged PDF is too large to email?

If your merged PDF exceeds email attachment limits (typically 10-25MB), you have several options: use our PDF compression tool to reduce file size, split the merged PDF into smaller parts using our PDF splitter, or use a file sharing service instead of email attachment.

Can I merge password-protected PDFs?

No, password-protected PDFs must be unlocked before merging. You'll need to remove the password protection using the original software that created the PDF or ask the document creator for an unprotected version. For security reasons, our tool does not attempt to bypass PDF password protection.

PDF Merging Best Practices

Optimize Before Merging

If your PDFs contain large images, consider compressing them first for a smaller final file size. This is especially helpful for email attachments.

Check Page Orientation

Ensure all pages have consistent orientation (portrait/landscape) before merging. Mixing orientations can make the final document harder to read.

Add a Table of Contents

For large merged documents, consider creating a cover page with a table of contents listing all included documents and their starting page numbers.

Watch File Size Limits

Email providers have attachment limits (typically 10-25MB). If your merged PDF is too large, use our PDF compression tool before sending.
