Turn TIFF files into a PDF

or drop them here
Choose at least one JPG or PNG image first.

TIFF to PDF turns standard and multi-page TIFF scanner files into a single checked PDF without uploading them. Every frame becomes a reorderable page, scanner resolution is used when the TIFF records it, and each frame is decoded in this browser tab. Keep the scanner page shape or fit every frame on A4 or US Letter, and the finished PDF is reopened and verified before download.

How to convert TIFF to PDF in your browser

  1. Choose TIFF files

    Pick one or more .tif or .tiff files, or drag them onto the page. Every frame in a multi-page TIFF is opened and listed in this tab.

  2. Check the page order

    Each TIFF frame becomes a visible page row. Move or remove rows before building the PDF, so a multi-page scan comes out in the right order.

  3. Choose the page fit

    Keep the scanner page shape, or fit every frame on A4 or US Letter with the margin you choose. Scanner resolution is used when the TIFF records it, so a 300 DPI scan comes out at its real paper size.

  4. Read the receipt, then download

    The result is reopened inside the browser. Its page count, page sizes, and embedded image dimensions must all match before the download button appears.

How does TIFF to PDF handle scanner output?

Each TIFF frame is decoded in memory, its orientation is applied, and transparent pixels are flattened onto white. The frame is then encoded as JPEG at quality 90. This keeps the decoded width and height, but it does not preserve the TIFF compression stream byte for byte. That is the trade a TIFF to PDF converter makes: convert the pixels once, keep the width and height, and accept a JPEG stream in place of the original.

A black and white fax scan is therefore larger as a PDF page than it was as a TIFF frame, while a photographic scan is usually smaller. When the TIFF records its scanner resolution, that number sets the page size, so a 300 DPI scan comes out at its real paper size instead of a giant sheet. The verifier reopens the completed PDF and checks the page count, every page size, and the pixel dimensions of each embedded page image before the download appears.

Compress PDF brings a heavy scan set back down, and Size breakdown names the pages responsible before you compress anything. Going the other way, PDF to TIFF renders PDF pages back into TIFF frames for a system that will accept nothing else.

When should I convert TIFF to PDF here?

TIFF is what scanners, fax gateways, and document archives produce. When the recipient cannot open that format, or their viewer shows only the first frame of a multi-page stack, converting the whole stack to PDF gives every frame a page that any reader displays, in order.

Sharing scanned documents. When a multi-page TIFF from an office scanner will not open on a phone or tablet, one PDF keeps every page in order and opens in any browser or reader.

Submitting legal or medical records. When a court, hospital, or insurer accepts PDF but not TIFF, convert the scan here and download a single file that meets the requirement.

Archiving fax output. Fax gateways still deliver TIFF files. Turn them into PDF for long-term storage that any PDF reader can open without a fax viewer.

Handing scans to a print shop. When a print shop asks for PDF instead of a multi-page TIFF, the scanner resolution is preserved so the pages print at their real paper size.

Each frame is decoded in this browser tab, so no file content reaches a server: usage data events carry only action names, counts, sizes and durations. To put the result beside documents you already have, use Merge PDF. To reorder or remove pages afterward, use Organize pages. For a folder holding several image formats, use Images to PDF.

TIFF to PDF frequently asked questions

Are my TIFF files uploaded to a server?
No. The TIFF decoder, PDF writer, and all output checks run in this browser tab. No file content leaves your device; usage data events carry only action names, counts, sizes and durations.
Does it read multi-page TIFF files?
Yes. Every readable TIFF frame becomes one PDF page and appears in the page-order list before conversion.
Does it support BigTIFF?
No. BigTIFF uses a different 64-bit container and is refused with an explanation. Standard TIFF files use version 42 and are supported.
Does TIFF to PDF change image quality?
TIFF frames are decoded and saved into the PDF as JPEG at quality 90. The decoded pixel width and height are kept and checked, but the stored TIFF bytes are not copied unchanged.
What happens to transparent TIFF pixels?
They are flattened onto white because a PDF page needs a visible background.
Does the output become searchable?
No. TIFF contains page images, not selectable characters. This conversion does not run OCR.
Is there a file size or page limit?
No account is required and there is no queue. Files are processed in this tab and held in memory, so very large sets depend on what your browser and device can handle.
What does the TIFF to PDF verification check cover?
It opens the completed PDF and checks the page count, every page size, and the pixel dimensions of each embedded page image. A failed result is not offered for download.
