A short, honest guide to TIFF and why it still matters.
TIFF (Tagged Image File Format) is one of the oldest raster image formats still in active use — and it has staying power for good reason. Created in the 1980s for the publishing industry, TIFF supports lossless compression, multiple pages in a single file, embedded metadata, and bit depths high enough for professional print work. It’s what museums, hospitals, and courts reach for when they need an image that won’t quietly degrade over the next decade.
Most people encounter TIFF in one of three contexts: scanning documents (TIFF is the default for multipage scans because JPG can’t hold multiple pages), professional printing (300 DPI minimum, often 600 for fine art), and long-term archival storage (TIFF is the preferred format of the Library of Congress for a reason). When people ask us why anyone would convert a PDF to TIFF, the answer is almost always one of those three.
"TIFF is the format you choose when you care more about the image surviving the next 40 years than about emailing it tomorrow.
When to reach for TIFF instead of PDF, JPG, or PNG
Pick TIFF when you need lossless quality for print, when you’re archiving for the long term, or when you work in a field where TIFF is the expected format — medicine, law, GIS, museum digitization. Everyone else is probably better served by another format:
- PDF — universal sharing, searchable text, anyone can open it
- JPG — small files for web photos where a little quality loss is fine
- PNG — graphics, logos, or anything needing transparency on the web
Is it actually safe to convert files online?
Honest answer: it depends on who’s handling your files. At PDFWiseTools, uploads travel over TLS encryption, files are processed on isolated temporary storage that no third party can reach, and everything is automatically deleted within 60 minutes. We don’t require an account, which means we never collect the kind of personal information that could be tied to your documents. For genuinely sensitive material — medical records, sealed legal filings, confidential business files — we’d still recommend converting locally if you can. For everything else, we’ve built what we’d want to use ourselves.
Things people ask.
Are these tools really free?
Yes, every tool is completely free with no usage limits, no watermarks on output, and no account requirement. There’s no pro tier we’re trying to sell you.
What happens to my files after I upload them?
Files are stored on isolated temporary storage and automatically deleted within 60 minutes. We never read, copy, share, or analyze your documents.
Is there a file size or batch limit?
Each file can be up to 200 MB, and you can upload up to 20 files per batch. For most documents this is more than enough.
Do I need to install anything?
No. Every tool runs entirely in your browser. No plugin, no extension, no desktop software. Works on Windows, Mac, Linux, Android, and iOS.
What DPI should I use for TIFF output?
150 DPI for screen viewing, 300 DPI for standard print, and 600 DPI for archival-grade or fine-art printing. When in doubt, 300 is a safe default.
Do you add watermarks to the output?
Never. The file you download is your original content, converted — nothing added, nothing branded, nothing stamped.
