How to convert TIFF to PDF
- Add your
.tifor.tifffile. A multipage TIFF is listed page by page, so you can see the whole document before converting anything. - Pick the pages you need, or leave every page selected. Reordering, rotating and removing pages all happen here, before the export.
- Press Export PDF. The pages come back as one PDF, in the order shown on screen.
- Nothing you do here changes the original file — the TIFF on your disk is left exactly as it was.
Multipage TIFF becomes a multipage PDF
A TIFF can hold one page or a few hundred, and scanners often write a whole document into a single file. Every page is read separately, so a 200-page scan arrives as 200 pages you can reorder or thin out, not as one image you have to accept whole.
Each page keeps its own size. A document that mixes A4 pages with a wider fold-out stays that way in the PDF; nothing is stretched to a uniform paper size. Pages that carry an orientation tag are turned the right way up before they go in, and any rotation you apply yourself is applied on top of that.
Which TIFF files work here
The compression types that scanners and document systems actually produce are covered: uncompressed, LZW, Deflate, PackBits, CCITT Group 3 and Group 4 fax compression, and JPEG-compressed TIFF. That covers the everyday cases — a black-and-white scan from an office multifunction device, a colour scan, a page exported from an imaging system.
TIFF is an old and very wide format, so a few variants are outside what this tool reads. When a file can't be used, the reason is stated: a file that isn't readable, a compression method that isn't supported yet, a variant that isn't supported yet, and a file too large to process safely are four different messages, not one vague failure.
What to expect from the file size
Black-and-white scans that use CCITT Group 4, and TIFF files that carry JPEG-compressed pages, are placed into the PDF without being decoded and re-compressed. The compressed page data is reused as-is, so the PDF ends up close to the size of the source — in our measurements a 20-page fax-compressed scan of 148 KB produced a 195 KB PDF.
Other compression types have no direct equivalent inside a PDF, so those pages are rendered first and then written into the page. For those, the PDF is not guaranteed to be the same size as the TIFF: a bulky uncompressed or LZW scan usually gets smaller, while a page that was already compressed very tightly can grow. What is preserved is how the page looks, not its byte count. When a job contains pages like that, the tool says so before you export.
The exported PDF holds page images. No text recognition is performed here, so the result is not a searchable PDF and you will not be able to select words in it — run OCR separately if that is what you need.
Everything happens on your device
The TIFF decoder and the PDF writer both run inside your browser tab. Your file is read locally, the PDF is written locally, nothing is uploaded to a server and there is no account to create. You can keep the network panel open while you work and watch that no file bytes go out.
It also means the work is done by your own device, so a long scan takes longer on a phone than on a laptop. For a big document, exporting the pages you actually need is the faster route.
Frequently asked questions
Does a multipage TIFF stay in the right order?
Yes. Pages are read in the order they appear in the file and exported in the order shown on screen. If you drag pages around before exporting, the PDF follows what you see, not the original order.
Are BigTIFF files supported?
Not yet. BigTIFF is a separate 64-bit variant of the format, and files that use it are refused with a message saying the variant isn't supported — they are not reported as damaged. Older JPEG-compressed TIFF (the pre-1994 'old JPEG' encoding) is not supported either.
Is my file uploaded to convert it?
No. Everything runs in your browser tab, so the file never leaves your device, and there is no upload queue. TIFF files can be up to 100 MB each; within that, very large scans are limited by your own device's memory.
Can I convert just a few pages of a large scan?
Yes, and for a long document that is usually the better move. Select the pages you want and export only those; the rest of the file is left untouched and the export finishes much faster.
Will the PDF look the same as the TIFF?
Page appearance, page order and page size are what the conversion preserves. Pages that keep their original compression are byte-for-byte the same image data as the source; pages that have to be rendered are written at a high resolution, so what you see matches, but the file is a new PDF rather than a container copy of the TIFF.
