Convert TIFF to PDF
Drop a TIFF on the image to PDF tool and each page of it becomes a page of the PDF, in the order the scanner wrote them. Add more TIFFs, JPGs or PNGs alongside, drag them into order, choose a page size, and download one PDF. Nothing is uploaded.
Why TIFF needs converting at all
TIFF is what scanners, fax software and document archives produce, because it can hold several pages and compress black-and-white text losslessly. It is also a format almost nothing on the web accepts: only Safari displays one, and most upload forms that ask for a document want a PDF. Converting once solves both.
How it works without uploading
Browsers cannot read TIFF, so the first time you drop one the page downloads a small open-source TIFF reader (UTIF.js, about 80 KB, from the jsDelivr CDN, pinned to an exact version and checked against a fingerprint). It turns each page into an image on your device, and the PDF is written from those. Your scan never leaves your computer.
What to expect
- Common TIFF compressions work: LZW, Deflate, PackBits and the Group 3 and Group 4 fax codecs, colour or black and white.
- Page size is your choice: fit the page to each image, or place every page on A4 or US Letter.
- Size: pages are stored as high-quality JPEG in the PDF, so a colour scan usually comes out smaller than the TIFF; a black-and-white fax may come out larger, because fax compression is extremely efficient for pure black and white.
- Up to 100 pages per TIFF.
