Turn a TIFF — including a multi-page one — into a PDF.
On your device. No watermark. No sign-up.
This tool is processed locally with JavaScript inside your browser tab. The document is not uploaded, stored or seen by a server, which makes it suitable for contracts, invoices, CVs and medical or financial records.
A TIFF file can hold many pages in one file — that is why scanners, fax servers and document archives use it. Each page inside the file is read separately and placed on its own PDF page, in the same order.
The tool tells you how many pages it found as soon as the file is added, so you can check that before converting. A one-page TIFF becomes a one-page PDF.
Only the first file is read per run. If you have several TIFFs, convert them one at a time and join the PDFs with Merge PDF.
Most TIFFs store their pixels with a compression, and the reader handles the ones real files use: uncompressed, LZW, Deflate, PackBits, and the CCITT fax codes that black-and-white scans use.
One combination is not supported: pages saved with JPEG compression inside the TIFF. That variant is rare outside some photo-editing exports, and the tool says so plainly instead of producing a blank page. Re-save the file as a normal TIFF or as JPG, then convert.
Very unusual colour layouts, such as CMYK from a print workflow, may come out with shifted colours, because the picture is redrawn from the channels the reader understands.
The pixels are decoded once and stored in the PDF as a lossless PNG. There is no JPEG step, so a scanned document does not get a second layer of damage on the way in.
That also means the PDF is often larger than the TIFF was. A TIFF is built for storage and can compress a scanned page very hard; the same page inside a PDF is heavier. Run the finished PDF through Compress PDF if it is going into an email or a portal with a size limit.
Fit to each page makes every PDF page exactly as large as the TIFF page, counting one pixel as one point. A 2480 × 3508 scan becomes a page of about 34 × 49 inches — correct for viewing, unusual for printing.
Choose A4 or Letter when the PDF will be printed, uploaded to a portal, or merged with other documents. Each page is then scaled to fit and centred, never stretched.
The margin slider adds up to 72 points (one inch) on every side. Use it when the PDF will be printed or hole-punched, not for a scan that already has its own white border.
Scanners and multi-function printers usually offer TIFF next to PDF and JPG. Fax servers deliver TIFF. Document management and medical or legal archives keep TIFF because it is lossless and can hold many pages.
Most forms and portals, however, ask for PDF. That is the whole job of this page: keep the pages and the quality, and hand over the format the other side accepts.
The TIFF is decoded with the UTIF library and the PDF is built with pdf-lib, both inside this browser tab. The file is read from your disk and never sent to a server, which matters for medical records, contracts and land documents. After your first visit the tool also works offline.
Yes. There is no account, no daily limit and no watermark on the PDF.
No. The TIFF is decoded and the PDF is built in your browser; the file never leaves your device.
Yes. Every page inside the TIFF becomes its own PDF page, in the same order.
No. The pixels are decoded once and stored losslessly as PNG in the PDF. There is no second JPEG compression.
A TIFF compresses a scanned page very hard for storage; the same page in a PDF is heavier. Compress the PDF afterwards if you need a smaller file.
Uncompressed, LZW, Deflate, PackBits and the CCITT fax codes. TIFF pages that use JPEG compression inside the file are not supported.
No, one file per run. Convert each TIFF and then join the PDFs with Merge PDF.
Not with this tool. Convert the TIFF to PDF here, then run that PDF through PDF to JPG, or open the TIFF in an image editor and save it as JPG.
A4 or Letter for printing, portals and merging. Fit to each page keeps the original proportions for viewing on screen.
Yes, though a very large scanned TIFF can run out of memory on an older phone. Try it on a computer if the file is over about 50 MB.
