PNG to TIFF without losing anything
PNG and TIFF are both lossless, so moving a picture from one to the other doesn't blur text, edges or colors. That makes this conversion ideal for logos, diagrams, charts, signatures, illustrations and screenshots, the kind of image where JPG compression would leave soft edges.
ConvertirDocs saves the TIFF without compression. Every pixel is stored exactly as it is, which is what printing and archiving workflows usually want, but the file will be considerably heavier than the PNG.
When a TIFF is required
You might be sending artwork to a print shop or a sign maker whose file requirements list TIFF. A publisher or a journal may ask for figures as TIFF. A records system at your office, a hospital or a public agency may only store TIFF. Some scanning, fax and layout programs also import TIFF more reliably than PNG.
In those cases you usually already have a perfect PNG exported from a design app, a chart tool or a screenshot. Converting it to TIFF gives you the format they ask for without redoing the work. If they also specify a resolution in DPI, set it with “Change image DPI” or “Resize image”, and confirm their exact requirements with them.
File size and large batches
An uncompressed TIFF grows with the pixel dimensions of the image. A small icon stays small, while a big poster-sized PNG becomes a very large file. If an upload portal has a size limit, reduce the dimensions with “Resize image” before converting.
You can convert many PNG files in one go and download them in a ZIP. On a phone, converting very large images in smaller groups is easier on memory.
Typical PNG files people convert
Most PNG files come from screens and design tools: exported logos and labels, charts from spreadsheets, figures for a paper, scanned drawings saved by a phone app, maps and floor plans, or screenshots of software that need to go into a manual. They're usually sharp and clean already, so the goal isn't to improve them but to hand them over in the format the other side expects, without introducing any blur or compression artifacts on the way.
Your images stay on your device
The conversion happens in your browser. Your images are never uploaded to a server or stored, so client artwork, internal diagrams and screenshots with private information stay with you. There's no account, no sign-up and no watermark.
The TIFF files carry no EXIF data. From the result you can keep working, for example sending the file to another ConvertirDocs tool, without selecting it again.
