TIFF to PDFの使い方
- 1
Drop the TIFF files
Add up to 10 .tif or .tiff files from a scanner, a fax inbox or an archive. A multi-page TIFF counts as one file.
- 2
Check every page
Each page of a multi-page TIFF gets its own preview, labelled with the file name and page number, so you can remove blank pages.
- 3
Fix order and paper size
Drag pages into order, rotate sideways scans, and choose A4 or Letter so large scans print at their real size.
- 4
Make the PDF
Press Create PDF and download one document containing every page you kept, in the order shown.
制限と Pro
Up to 10 files per PDF, 50 MB each; up to 200 pages from each multi-page TIFF.
Pro accepts 500 files of up to 4 GB and up to 5,000 pages from each TIFF. Pro を見る
TIFF to PDF について
TIFF is the old workhorse of scanning: document scanners, fax servers, medical and legal archives and many multifunction printers still save pages as .tif files, often with dozens of pages in one file. Browsers other than Safari can't display TIFF at all, and most portals want PDF, so this page reads TIFF itself. UTIF.js, a small open-source decoder running in a Web Worker, handles uncompressed, LZW, PackBits, Deflate and JPEG-compressed TIFFs as well as CCITT Group 3 and Group 4, the compressions fax machines use for black-and-white pages.
Every page of a multi-page TIFF becomes a separate PDF page that you can reorder, rotate or delete before building the document. Black-and-white pages are stored as lossless PNG, which keeps thin strokes and small print exact and stays compact; colour and greyscale pages are stored as high-quality JPEG at 92%. Reduced-size preview copies that some scanners write into the file next to each page are skipped, so they don't show up as extra pages.
Scanners record pages at 200 or 300 DPI, but Same as image sizes pages at 96 pixels per inch, which makes a 300 DPI scan huge on paper; choose A4 or US Letter with Fit instead and the page prints at its normal size. The result is a picture of each page: the text isn't searchable until you run OCR on the finished PDF. Orientation flags inside the TIFF are not applied, so use the rotate button on any page that comes out sideways.
プライバシー
The TIFF files are decoded by UTIF.js in a Web Worker in this tab and the PDF is written by pdf-lib in another worker; neither the scans nor the PDF are uploaded. That matters for the medical records, contracts and faxes TIFF files often contain.
