How many PDF files can I merge at once?

You can merge dozens of PDF files simultaneously. Since processing happens locally in your browser, the limit depends on your device's memory rather than our server capacity.

Is it safe to upload my private documents?

Yes, 100%. Our tool uses 'Local-First' technology. Your PDFs are processed directly in your browser and are never uploaded to any server. Your privacy is guaranteed.

Can I rearrange pages before merging?

Absolutely! After uploading, you can drag and drop individual pages to change their order, rotate specific pages, or remove unwanted ones before creating the final PDF.

Will merging affect the quality of my PDF?

No. Our merging engine preserves the original quality of your documents, including high-resolution images, vectors, and fonts.

Can I merge password-protected PDFs?

The current version supports merging standard, unprotected PDFs. For password-protected files, you'll need to remove the protection first before merging.

What is the maximum file size I can upload?

We support files up to 100MB each. Since all processing is browser-side, larger files may take longer to process depending on your internet speed (for initial loading) and device CPU.
