TIFF is what scanners, publishing pipelines, and scientific instruments produce — and what almost nothing else wants to open: browsers won't display it, chat apps reject it, and half the tools that claim support choke on its compression variants. PNG is the natural exit — lossless like TIFF, but universally understood. The typical traveler here has a scanned document, an archived photo, or a print asset that needs to live on the web or in an ordinary editor.
The conversion is pixel-exact: your TIFF decodes entirely on your device and re-encodes to lossless PNG with nothing altered and nothing uploaded. Two honest caveats. Photographic content stays large in PNG — that's lossless physics, and if a small file matters more than perfect fidelity, TIFF to JPG is the right page. And multi-page TIFFs export the first page only, so a fifty-page scan needs its pages split before it arrives here.
How it works
- Drop your file
Any common format, any size. Nothing is uploaded — the tool runs in your browser.
- Choose quality or size
Pick a quality preset, set an exact KB target, or switch the output format — tuned for tiff to png.
- Download
Your converted file is ready on your device — nothing to wait for, nothing to delete from a server.
Frequently asked questions
Is the TIFF to PNG conversion truly lossless?
Yes — PNG stores exactly the pixels your TIFF decodes to, with no further loss no matter how often the file is reopened and saved. The one nuance: some TIFFs carry JPEG-compressed data internally, and any loss there happened when the TIFF was made, not here.
What happens to a multi-page TIFF?
Only the first page is exported — a real limitation of this tool. Multi-page TIFFs are common for scanned documents, so if you need every page, split the TIFF into single-page files first, or use a document workflow that outputs PDF instead.
Why is the PNG as big as, or bigger than, the TIFF?
Lossless formats cannot compress photographic detail much — that is physics, not a bug. PNG earns its size when the image heads into an editor or an archive. If you just need something small to share or embed, TIFF to JPG produces a fraction of the size.
Does my TIFF get uploaded to a server?
No — the file is decoded and re-encoded entirely in your browser, on your device. Nothing is transmitted anywhere, which matters when the TIFF is a scanned contract, an ID document, or medical imagery you would rather keep to yourself.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
