How this works in your browser
TIFF is a container format rather than a single compression scheme: a file is a set of tagged directory entries describing width, height, bit depth, row layout and where the pixel data sits, followed by the pixels themselves. That flexibility is why TIFF has survived in print and archival work for decades, and why one TIFF can be uncompressed while another uses LZW or JPEG internally. This tool decodes your PNG onto a canvas and writes a baseline uncompressed RGB TIFF, the most conservatively compatible variant, so it opens correctly in Photoshop, Preview, GIMP and older prepress software rather than tripping over a compression mode some tool in the chain does not support.
PNG to TIFF vs. traditional online converters
| Feature | PNG to TIFF (in-browser) | Traditional online converters |
|---|---|---|
| File upload required | No - never leaves your device | Yes - file is sent to a server |
| Processing queue | None - starts instantly | Often, especially at peak times |
| Watermark on output | Never | Common on free plans |
| Usage limits | None - free, unlimited use | Often capped per day or file size |
| Works offline once loaded | Yes, for most tools | No - requires a live connection |
| Account required | No | Often, for anything beyond a trial |
Who uses PNG to TIFF
Print vendor submissions
Meet a printer or publisher intake specification that names TIFF as the accepted format.
Archival and records storage
Store images in a long-established format that libraries and institutions have committed to keeping readable.
Professional editing handoff
Provide a flat, uncompressed file to a retoucher or designer working in software built around TIFF.
How to use PNG to TIFF
- 1
Open the PNG to TIFF converter
Go to tools.slaytic.com and open the PNG to TIFF tool. No sign-up or account required.
- 2
Drop your PNG file
Add the image. Transparent areas will be flattened onto white, since the output has no alpha channel.
- 3
Download the TIFF
Save the baseline TIFF, ready to hand to a print vendor or open in professional editing software.
Frequently asked questions
Why would I need TIFF instead of PNG?
Some print vendors, scanners, and professional photo-editing workflows specifically require TIFF for file intake.
Will the TIFF file be larger than the PNG?
Yes, usually significantly, since this tool produces an uncompressed TIFF, while PNG compresses losslessly.
What happens to transparent areas?
This tool outputs a standard RGB TIFF without an alpha channel, so transparent areas are filled with white.
Is the TIFF in CMYK for printing?
No, the output is RGB. Print shops that need CMYK usually convert during prepress using their own colour profile, which produces better results than a generic browser-side conversion would. If your vendor insists on receiving CMYK, ask which profile they use and convert in Photoshop or Affinity.
Does the image quality change?
No. Both PNG and this uncompressed TIFF store exact pixel values, so every colour survives the conversion unchanged. Only the container and the file size are different.
Will the TIFF keep my image DPI?
Treat the pixel dimensions as what matters. DPI is only a tag describing intended print size, and print workflows generally recalculate it from the physical dimensions you order. A 3000 pixel wide image prints well at 10 inches regardless of what the tag says.
Is my image uploaded anywhere?
No. The TIFF is assembled inside your browser tab.
