Convert PNG to TIFF
This makes a TIFF out of the PNG you already have. TIFF is what print shops, scanners and archives ask for when a picture has to stay pristine. Worth knowing: a TIFF will not open in a browser tab, so it is a file for software rather than for the web. Your file never leaves your computer.

How to convert PNG to TIFF
- 1 Drop your PNG .png file onto the page, or click to browse for it.
- 2 Set the quality, or leave the default, which keeps the file small without anything showing.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the TIFF, or add more files and do the whole set in one go.
Why convert PNG to TIFF
- Keeps every detail and every shade, with proper colour management.
- Multiple pages in a single file, useful for scanned documents.
- Document scanning, using multi-page TIFF as a fax-era standard.
- PNG: encoding at maximum compression is slow on large images.

Quality and what changes
TIFF stores the same content under a different set of rules, so what matters here is compatibility rather than picture quality. Convert once from the best source you have rather than through a chain of intermediate files.
- Browsers will not display a TIFF, so it downloads rather than opening in a tab.
- One TIFF limitation to keep in mind: the flexibility means some TIFF variants are unreadable elsewhere.
Questions about PNG to TIFF
Can I open a TIFF in a browser?
No. No mainstream browser renders TIFF natively, so it will download rather than display. That is fine when the file is heading into desktop software or an archive, and a problem if it is going on a web page.
Is my PNG file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your PNG is read straight from your own disk, converted on your machine and handed back as a TIFF. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several PNG files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate TIFF downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
