How to Convert TIFF Images to a PDF

1

Add One or Many TIFFs

Drop your TIFF files (single-page or multi-page) onto the upload zone or pick them from your device. Files stay in your browser; nothing is uploaded.

2

Pick Page Size and Order

Drag thumbnails to set the page order, pick A4, US Letter or original size and choose portrait or landscape orientation. Multi-page TIFFs are expanded so each TIFF page becomes its own PDF page.

3

Download the Combined PDF

Click convert to bundle every TIFF into a single PDF with the chosen layout. Open it in any viewer, archive it or send it by email — the source TIFFs stay untouched.

Frequently Asked Questions

Does it support multi-page TIFFs?

Yes. ZentoPDF detects multi-page TIFFs (common for faxes, scanners and DICOM secondary capture) and expands every page into its own PDF page, so a 10-page TIFF + a 5-page TIFF produces a clean 15-page PDF in one go.

Is the image quality preserved?

Yes. ZentoPDF embeds the TIFF pixels into the PDF without re-encoding, so the result is exactly as sharp as your source images. No JPEG artefacts, no blurring — bitwise-identical pixel data.

Are my files uploaded?

No. The whole conversion happens client-side in your browser using a WASM-based TIFF decoder and pdf-lib. Your TIFFs and the resulting PDF never leave your device.

Can I combine TIFFs of different sizes?

Yes. Each TIFF is fit into the selected PDF page size while preserving its aspect ratio, or you can keep the original TIFF dimensions per page if you prefer one viewport per image.

Is the converter free?

Yes — 100% free, no signup, no watermark, no daily quota. Convert as many TIFFs as you like to PDF, for personal or professional use.
