TIFF to PDF is the scanner's afterlife problem: flatbeds, office copiers, and fax software have saved scans as TIFF for decades, and the format is superb for archiving — but try attaching one to a portal or emailing it to a lawyer and you meet blank previews and rejected uploads. PDF is what the receiving side expects, and since scans are usually contracts, records, and IDs, converting them locally matters.
Drop several TIFFs together and each becomes an A4 page in a single document, in the order you picked — decoding and PDF assembly both happen in your browser, so the scans never leave your device, and the image data embeds losslessly. One honest caveat: a multi-page TIFF contributes only its first page here. If your scanner bundled a whole document into one file, re-export the scan as separate files — one per page — or convert each page-file on its own.

Frequently asked questions
Why does only the first page of my TIFF appear?
TIFF can hold multiple pages in one file, and this tool reads the first page of each file. For a multi-page original, re-export from your scanner as one file per page — most scanner software offers this — or convert each page-file separately and the pages line up as separate files in one PDF.
Do my scans lose quality in the PDF?
No — the TIFF is decoded at full resolution and embedded into the PDF losslessly, with no re-compression. Every dot your scanner captured is what the page shows and what comes out of the printer, which is exactly what signed documents require.
Can I combine several TIFF scans into one PDF?
Yes — drop them together and each file becomes its own A4 page in a single document, first picked, first page. The list under the dropzone lets you reorder with the arrows or remove a file with the × before creating the PDF.
Are my scans uploaded anywhere during conversion?
No — TIFF decoding and PDF assembly both run inside your browser, and the files never leave your device. Scans are disproportionately contracts, IDs, and medical or legal records, which is precisely the material that should never sit on someone else's server.
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.
