Who asks for TIFF
TIFF is still the expected format in several places. Some print shops and photo labs list TIFF in their file requirements. Publishers, newspapers and stock or archive services sometimes want images delivered as TIFF. Document management and records systems in offices, hospitals and government departments are often set up to store TIFF. Older scanning and fax workflows, as well as some layout and editing software, also work best with it.
If you only have a JPG and the instructions say TIFF, this tool gives you a file with the right format and extension in a few seconds.
What converting to TIFF does and doesn't do
ConvertirDocs saves TIFF without compression. That means no new quality loss is added: every pixel of your JPG is stored exactly as it is. It also means the file is heavy, often many times larger than the JPG, so keep that in mind before attaching it to an email.
Converting cannot add detail that the JPG doesn't have. If the photo was compressed or small, the TIFF will be the same picture in a bigger file. What you gain is a format that the receiving system accepts and that won't lose anything more if it's edited and saved again. If the print shop also requires a specific resolution, use “Change image DPI” or “Resize image” first, and check their exact requirements.
Keeping the file size under control
Because the output is uncompressed, the size depends on the pixel dimensions of the photo. A large phone photo turns into a large TIFF. If a portal has an upload limit, reduce the dimensions with “Resize image” before converting, rather than trying to compress the TIFF afterward.
When you convert several photos, download them together in a ZIP. For very large batches on a phone, converting in smaller groups is gentler on memory.
Private, free and without sign-up
The conversion runs in your browser, so your photos are never uploaded or stored on a server. There's no account, no watermark and no limit on how many files you convert.
The TIFF files carry no EXIF data, so details like the GPS location your phone may have recorded aren't copied into them. The camera orientation is applied first, so portrait photos stay upright.
