TIFF files are everywhere in scanning, faxing, and archiving — but they're awkward to share. Many phones can't preview them, email clients handle them inconsistently, and most people you send one to won't know what to do with it. Converting TIFF to PDF fixes all of that in seconds, and you can do it free online without installing anything.
What is a TIFF file?
TIFF (Tagged Image File Format) is a raster image format built for quality. Scanners love it because it stores images losslessly — every pixel of the original scan is preserved. Fax machines, document archives, and print shops still use TIFF heavily for the same reason.
The tradeoff is size and compatibility. A single scanned page saved as TIFF can be several megabytes, and TIFF isn't natively viewable in most browsers or on phones. PDF keeps the quality, shrinks the file, and opens everywhere.
Why convert TIFF to PDF?
- Universal compatibility. PDFs open on every phone, tablet, and computer with no special software.
- Smaller files. A TIFF converted to PDF is typically much smaller, which matters for email attachments and uploads.
- Multi-page documents. Scanners often save each page as a separate TIFF. Converting to PDF merges them into one document.
- Easy sharing. Portals, job applications, and government forms accept PDF — rarely TIFF.
How to convert TIFF to PDF online free (3 steps)
The fastest way is PurePDF's free TIFF to PDF converter at https://www.purepdf.net/tiff-to-pdf. It runs entirely in your browser using WebAssembly, so your files never leave your device — nothing is uploaded to a server.
- Upload your TIFF files. Click to browse or drag and drop. You can add multiple TIFFs at once — batch conversion is supported.
- Convert. The tool processes each TIFF locally in your browser. A multi-page TIFF becomes a multi-page PDF automatically, with pages in the right order.
- Download your PDF. Save the converted file. No signup, no watermark, no account needed.
That's it. A scan that took a minute to create takes seconds to convert.
Converting multi-page TIFFs
This is the case most people care about. Many scanners produce multi-page TIFFs — one file containing every page of the document. When you convert a multi-page TIFF to PDF, each TIFF frame becomes a PDF page in sequence, so a 10-page scan becomes a 10-page PDF.
If your scanner instead saved each page as a separate TIFF file, upload them all at once: batch conversion handles the whole set, and you can then merge the resulting PDFs with a free merge tool if you want a single document.
TIFF to PDF without losing quality
Because TIFF is lossless, people worry conversion will degrade their scans. A straightforward TIFF-to-PDF conversion embeds the image data as-is — there's no re-compression step that throws quality away. Your text stays sharp and fine print stays readable, which is exactly what you want for archived documents, receipts, and legal scans.
Common problems and fixes
"My TIFF is huge." Normal — lossless scans are big. Converting to PDF alone usually shrinks the file substantially. If it's still too large for an upload limit, run it through a PDF compressor afterward.
"The recipient can't open my TIFF." That's the compatibility problem this conversion solves. After converting, anyone can open the PDF in a browser.
"My scanner saved 20 separate TIFFs." Upload them all in one batch, convert, then merge the PDFs into a single file.
"I need this for a fax or archive." PDF is the safer long-term choice: it's an open standard (ISO 32000), searchable when the source has a text layer, and supported by every archive system.
FAQ
Is converting TIFF to PDF free? Yes. PurePDF's TIFF to PDF converter is free with no signup and no watermark.
Do my files get uploaded to a server? No. The conversion runs in your browser via WebAssembly, so your documents stay on your device.
Can I convert multiple TIFFs at once? Yes — batch conversion is supported. Add all your files and convert them together.
Will a multi-page TIFF become a multi-page PDF? Yes. Each frame of a multi-page TIFF becomes a page in the resulting PDF, in order.
Does conversion reduce image quality? No. The image data is embedded without lossy re-compression, so scan quality is preserved.
The bottom line
TIFF is a great format for scanning and archiving, but a poor format for sharing. Converting to PDF gives you universal compatibility, smaller files, and proper multi-page documents — free, in seconds, without uploading your files anywhere. Try it at https://www.purepdf.net/tiff-to-pdf.
