How it works

How to convert TIFF to PDF

  1. Add your TIFF files

  2. Check the settings

    Choose a page size (the image's own size, A4, or US Letter), margins, and whether to combine everything into one PDF.

The formats

TIFF and PDF at a glance

  • What is a TIFF file?

    TIFF is a flexible, high-quality image format used for printing, scanning, archiving, and professional photography. It's usually lossless and can hold several pages in one file, which is why scanners and fax software use it. Files are large, and most browsers can't display TIFF images. It opens in macOS Preview, Windows Photos, Photoshop, GIMP, Affinity Photo, and most scanning, printing, and fax software. Safari is the only major browser that shows it.

  • What is a PDF file?

    PDF is the standard format for sharing documents that should look the same everywhere. It fixes the layout, fonts, and images of every page, which is great for reading and printing but makes editing hard. A PDF can contain real text or only scanned pictures of pages. It opens in every browser, Adobe Acrobat Reader, macOS Preview, Microsoft Edge on Windows, phones, and Google Drive.

Good to know

What changes when you convert TIFF to PDF

  • Each image becomes one page, in the order you add them. You can drag files to reorder them before converting.
  • Photos are embedded as high-quality JPG and graphics with transparency as PNG, so nothing visible is lost.
  • Every page of a multi-page TIFF becomes its own PDF page.
  • Very large images, around 100 megapixels or more, can exceed what the browser allows, especially on phones.

FAQ

Questions, answered

Is this TIFF to PDF converter free?

Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.

Are my files uploaded anywhere?

No. The conversion runs inside your browser with pdf-lib and Mozilla's pdf.js, so your files never leave your device. Once the page has loaded, it even works offline.

Can I convert several TIFF files at once?

Yes. Add as many images as you like, then combine them into one PDF or make a separate PDF for each. Drag them into the order you want first.

Does it work on iPhone, Android, Mac, and Windows?

Yes. It works in Chrome, Edge, Firefox, and Safari, on computers and phones.

What can open a PDF file?

Every browser, Adobe Acrobat Reader, macOS Preview, Microsoft Edge on Windows, phones, and Google Drive.

Is there a file size limit?

There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle images up to about 100 megapixels.
