Convert TIFF to PDF Online — Free
Convert TIFF scans or archival images to PDF online — ideal for document scans, print proofs, or any TIFF that needs universal sharing. Browser-based, no upload.

- 1
Add your TIFF file
Drop or select a .tiff file. Files up to 50MB process locally in your browser — nothing uploaded.
- 2
Run the conversion
TIFF files render via the browser's image decoder, rasterize to a Canvas, then embed into the PDF. For multi-page TIFFs only the first page converts today; full multi-page support (one TIFF page per PDF page) is on our roadmap.
- 3
Download your PDF
One click saves the result as a .pdf file. Your original file stays on your device.
Why convert TIFF to PDF?
Scanned documents, fax archives, and print-production files are often delivered as TIFF because of its lossless compression and multi-page container support, but TIFF viewing is inconsistent outside specialized software. PDF is the universal exchange format for documents — making sharing, archiving, and viewing far easier across any OS, browser, or email client.
Common TIFF to PDF use cases
- Converting scanned legal or medical documents from TIFF archives to PDF for sharing with clients or external reviewers
- Turning historical archive TIFFs (library scans, microfilm digitizations) into PDF for online publication
- Packaging print-production TIFFs for a client proof that needs to be viewable on any device
- Converting GIS or engineering CAD exports saved as TIFF into PDF for inclusion in a technical report
What file size to expect
A 300-dpi uncompressed document TIFF at 8.5×11 inches (~25 MB) becomes a PDF of roughly 3-8 MB — PDF's internal compression (FlateDecode) shrinks uncompressed pixel data considerably. LZW-compressed TIFFs see smaller PDF savings. For maximum PDF compression on scanned text, use our Compress PDF tool after generation, or pre-convert TIFFs to JPG.
Technical notes: TIFF → PDF
TIFF's diverse internal encodings (uncompressed, LZW, Deflate, PackBits, CCITT fax, JPEG-in-TIFF) require browser-side decoding before PDF embedding. Browser TIFF support varies — Safari handles the most, Chrome/Edge handle common variants, Firefox support is limited. Once decoded to a Canvas, the pixel data re-encodes to JPG or flate-compressed PNG for PDF embedding. Multi-page TIFFs use only the first IFD (image file directory). 16-bit-per-channel color is truncated to 8-bit during Canvas conversion.
Compatibility and browser support
Generated PDFs open universally in Acrobat, Preview, Edge, Chrome, Firefox, Safari, and mobile readers. TIFF input compatibility depends on the browser: Safari is most permissive; Firefox is most limited. If a TIFF fails to load, open it in IrfanView (Windows) or Preview (macOS) and export to a simpler variant (uncompressed RGB) first.

Frequently Asked Questions
Multi-page TIFF?
First page only today. Full multi-page support (each TIFF page as a separate PDF page) is on our roadmap.
Will the PDF be smaller than the TIFF?
Often yes — uncompressed TIFFs shrink significantly inside a PDF via FlateDecode compression. Already-compressed TIFFs (LZW/Deflate) see smaller savings but the PDF is still more universally accessible.
Quality preserved?
Embedded losslessly from the decoded pixels. Any 16-bit color depth in the source TIFF is truncated to 8-bit during Canvas decoding — avoid this tool for color-critical print workflows.
CMYK TIFFs?
The browser Canvas assumes RGB. CMYK TIFFs may decode with color shifts or fail to load. Convert CMYK → RGB first in Photoshop, GIMP, or IrfanView.
Can I combine multiple TIFFs into one PDF?
Today: convert each TIFF separately, then use Image to PDF to bundle. Soon: native multi-TIFF support in a single step.
Will OCR be included?
No — this tool produces image-based PDFs without a searchable text layer. Use Adobe Acrobat's OCR or a dedicated OCR tool (Tesseract) on the output PDF for searchable text.
