PDF Tools

Is my PDF uploaded to a server during processing?

No. All PDF processing happens locally in your browser. Your files never leave your device.

What PDF file size is supported?

Since processing runs locally in your browser, file size depends on your device memory. PDFs under 100MB generally process smoothly.

Can I merge PDFs without losing quality?

Yes. ToolPure uses lossless merging — the output PDF preserves original resolution, color depth, and embedded fonts. All processing happens locally in your browser, so your documents never leave your device.

How many PDF files can I process at once?

You can merge up to 50 PDF files in a single operation, with each file up to 2GB. Files are processed in the order you add them, and you can drag to reorder before merging.

What PDF standards and versions are supported?

The tools support PDF versions 1.0 through 2.0 (ISO 32000-2), including PDF/A archival standard. Encrypted PDFs require the correct password for processing.

🔒 Privacy: All processing happens locally in your browser. Your files and data never leave your device — no upload, no server, no tracking.
