Frequently asked questions
Is TIFF to PDF really free?
Yes — free and unlimited. No sign-up, no watermarks, no daily caps, no file-size limits. Convert as many files as you like.
Are my files uploaded anywhere?
No. Conversion runs entirely in your browser tab — there is no upload endpoint, so your file’s bytes never leave your device. You can even convert offline after the first load.
Can I convert sensitive or work documents?
Yes. Because nothing is uploaded, private files stay private. That makes Optimal Convert suitable for GDPR- and HIPAA-sensitive workflows without a data-processing agreement.
Will converting TIFF to PDF lose quality?
PNG is lossless; JPG and WebP re-compress the decoded pixels. Optimal Convert encodes PDF at 92% quality by default, which is visually lossless for most images, and you can raise or lower it from the converter.

Private by design
This page runs entirely in your browser. Files are read, converted and saved on your own device using WebAssembly and the browser’s native codecs — nothing is uploaded, there is no account, and your bytes never leave your machine. Not even we can see them.
