When you would use this

Situations, not settings.

A scanner or fax that hands you a TIFF
Office scanners, document management systems and older fax software still default to TIFF, and almost nothing else opens it.
An upload form that will not take one
Job portals, government forms and print shops ask for JPG, and a TIFF is rejected before anyone looks at it.
A photo archive you want to actually browse
TIFFs do not show thumbnails or previews in most viewers, so a folder of scans is a list of filenames until they are converted.

How it works / no cloud

A conversion engine, not an upload form.

No browser can display a TIFF, so filetity decodes it here rather than handing the file to the browser and hoping. The reader covers uncompressed, LZW with the horizontal predictor, Deflate, CCITT Group 3 and Group 4 fax, big and little endian byte order, RGB and RGBA, 8 and 16 bit grey, palette colour and 1 bit black and white, then draws the pixels on a canvas and encodes a JPG at the quality you pick. Everything outside that set is refused by name instead of guessed at, because a decoder that quietly returns a blank image is worse than one that says no. Nothing is uploaded.

Straight answers

No accordion. Nothing hidden.

Is it free?
Yes, with no watermark and no page limit.
Does it need an account?
No. There is no account system.
Is my file processed on my device?
Yes. The file is read by your browser and never uploaded. There is no server to send it to.
What formats are supported?
TIFF and TIF in. JPG out, one file per image, or a ZIP when you convert several.
What are the limits?
Scans work, including the fax formats. CCITT Group 3 and Group 4, which is what fax machines and most document scanners write, are decoded here, in both bit orders and both polarities. What is still refused is refused by name rather than handed back damaged: PackBits, JPEG inside a TIFF, CMYK colour, floating point samples, separate colour planes, and tiled colour images. A multi-page TIFF is refused too, and says how many pages it has, because one image in means one file out here. Worth knowing: the CCITT decoder has been tested against files written by libtiff and by Pillow, not against output from a physical fax machine, so an unusually old file may still be turned away.
Does it work on mobile?
Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
Does it work offline?
Yes. Nothing is downloaded to make this work, so it keeps working with no network connection once the page has loaded.
Is TIF the same as TIFF?
Yes, one format with two spellings, and this page takes both. TIF is the three letter version that MS-DOS filenames forced, the same reason JPEG also gets written JPG. Nothing inside the file differs.
Why can I not just open the TIFF in my browser?
Because no browser decodes TIFF. Chrome, Firefox, Safari and Edge all handle JPG, PNG, WebP, GIF and AVIF, and none of them handles this one, which is why a TIFF downloads instead of opening in a tab. filetity carries its own TIFF reader so the decode happens on your machine anyway.
Will the JPG lose quality?
Some, once. TIFF is usually lossless and JPG is not, so this is a fresh lossy encode and the quality control decides how much is thrown away. If the file is a document scan or artwork you will edit again, convert to PNG instead, which keeps every pixel.
My TIFF has several pages. What happens?
It is refused, and the message says how many pages it found. One image in means one file out on this page, and quietly converting only the first page would hand you a file that looks right and is missing most of the document.
