PDF Merging FAQ

What are the free plan limits?

Visitors can process up to 25 files or 100 MB total for free, covering the vast majority of everyday needs. Need more? Upgrade to Pro for 500 files / 2 GB.

What file formats are supported?

Beyond PDF, we support Word (DOC/DOCX), Excel (XLS/XLSX), PPT (PPT/PPTX), images (JPG/PNG/GIF/BMP/WEBP/HEIC/AVIF), TIFF, CAD (DWG/DXF), AI, PSD, ODT, TXT, RTF, and more. The system auto-converts everything to PDF before merging.

Will mixing formats degrade the original quality?

Absolutely not. The engine uses native-level parsing to preserve 100% of the original text resolution, image DPI, and internal layout formatting.

Is it safe to merge PDFs containing confidential contracts?

Your files are safe. All data is transferred via 256-bit encryption, processed on EU-based servers under GDPR compliance, and permanently deleted after processing.

Can I rearrange pages before merging?

Yes, in two ways: drag entire files to reorder in File Mode, or switch to Page Mode to pick individual pages from different PDFs and arrange them freely. You can also rotate individual pages.

Can I merge encrypted PDFs?

Encrypted PDFs need to be unlocked first. Use Dpdf's "Unlock PDF" tool to remove the password in one click, then merge.

Can I continue processing after merging?

Yes. After merging, the system recommends follow-up tools like compression, watermarking, and format conversion. Click to continue — no re-uploading needed. For example, if the file is too large, use the "Compress PDF" tool to reduce its size instantly.
