TIFF to PDF converter, every page kept
Turn a multi-page TIFF — a fax, a scanner batch, an archive export — into one PDF with every page, at the paper size the file says. Black-and-white pages stay crisp and small. Nothing is uploaded.

From the TIFF: the size the scan really was, worked out from its resolution (a 200 DPI fax page comes out at its true 8.5 × 11 in). A4 or Letter fits every page to that paper.
Black-and-white pages are always kept exactly, as 1-bit images. This only decides how color and gray pages are stored: lossless is pixel-perfect and much larger.

How to convert a multi-page TIFF to PDF
-
Add your TIFFs: Drop one TIFF or several. Each file’s pages are counted, thumbnails skipped, in the order you list the files.
-
Check the settings: Keep the page size the TIFF gives, or fit every page to A4 or US Letter. Black-and-white pages are kept exactly as 1-bit images.
-
Save the result: Convert. Every page of every TIFF is a page of the PDF, sharp and as small as it can be.
Why it doesn’t upload
TIFF is what faxes, document scanners and records systems produce: signed forms, medical records, court filings, insurance claims. Those are exactly the files that shouldn’t go to a converter’s server. Here the TIFF is decoded and the PDF written inside your browser tab.
Check it in your browser’s Network tabWorth knowing
- TIFF pages that are thumbnails or reduced-size copies of another page are left out, as they should be. Every full page is kept.
- Layers, alpha channels and CMYK color from print TIFFs are flattened to RGB on white. For print production, convert in your print software instead.
- Pages without resolution information are sized as if scanned at 200 DPI, the most common document-scanner setting. Choose A4 or Letter if that guess is off.
- Very large TIFFs (big engineering drawings, 600 DPI color scans) are limited by your device’s memory: a phone may stop on a file a laptop handles.
Under the hood
What happens to your file
The TIFF is decoded by UTIF.js, page by page: every image file directory (IFD) that isn’t a thumbnail (NewSubfileType bit 0) is one page. Its paper size comes from the XResolution, YResolution and ResolutionUnit tags. Black-and-white pages are written into the PDF as 1-bit DeviceGray image XObjects with Flate compression, bit for bit as scanned; color and gray pages as JPEG, or as 8-bit Flate when lossless is chosen. The PDF is assembled with pdf-lib.

Why convert a TIFF to PDF in your browser?
TIFF is the format faxes, document scanners and records systems still produce, and it is awkward everywhere else: phones preview only the first page, email clients show an attachment icon, and many web forms accept PDF only. Converting to PDF makes it a document anyone can open — but only if every page survives, which is where many image converters fail: they read a TIFF like a photo and keep one frame.
Here each page of the TIFF is a page of the PDF, at the size it was scanned, and black-and-white pages are kept bit for bit. The file never leaves your device.
When people convert TIFF files to PDF
-
Fax to PDF
An eFax or fax-to-email service delivers a multi-page .tif; turn it into a PDF you can forward, sign or upload.
-
Scanner batches
Office scanners often save a stack of pages as one TIFF. One click makes it a PDF with every page in order.
-
Medical and legal records
Records exported from hospital, court or insurance systems arrive as TIFF; convert them without sending them to a stranger’s server.
-
Combining several TIFFs
Add many .tif files, order them, and get one PDF — useful for a claim or an application pack.
-
Archive and microfilm exports
Library and archive scans are often 1-bit TIFFs; kept as 1-bit, they stay tiny in the PDF.
Tips for converting TIFF to PDF
- Keep From the TIFF as the page size to get the real dimensions; choose A4 or Letter only if a portal needs one paper size.
- Black-and-white pages are already as small as they get. If the PDF is large, it is the color pages: keep Smaller (JPEG).
- Pages in the wrong order after converting several files? Reorder the files in the list and convert again.
- Need page images back out? PDF to JPG saves every page as JPG or PNG.
Questions
How do I convert a multi-page TIFF to one PDF?
Drop the TIFF here and press Convert to PDF. Every page in the file becomes a page of the PDF, in order — nothing to split or recombine.
Why did another converter give me only one page?
Many image converters read a TIFF like a photo and take only its first (or largest) frame. A multi-page TIFF is a stack of pages; this reads every one.
Will a fax TIFF stay readable?
Yes. Fax and black-and-white scan pages are stored as 1-bit images, exactly as received, with lossless compression. Nothing is blurred and each page stays around tens of kilobytes.
Can I convert several TIFF files into one PDF?
Yes. Add them all, put them in order with the arrows, and they become one PDF. Turn off “Put all the TIFFs in one PDF” under Advanced for one PDF per TIFF.
Is the TIFF uploaded?
No. The file is read and the PDF written in your browser; nothing is sent to a server.
Can I convert a PDF back to TIFF?
PDF to JPG saves each page as an image (JPG or PNG). Multi-page TIFF output isn’t offered.
