This TIFF to PNG converter processes everything inside your browser. Your files are never uploaded to any server — the conversion happens entirely on your device. Drop the file, download the PNG, and nothing has left your computer.
What "no upload" actually means for your files
Most online converters work by sending your file to a remote server, converting it there, and returning a download link. Your file sits on someone else's infrastructure until it is deleted — and you have no way to verify when that actually happens.
A browser-based converter is different. The conversion engine is downloaded to your browser when you open the page. All processing uses your device's own memory and computing power. Your file is read locally, processed locally, and saved to your download folder. No network request containing your image data is ever made.

Industries where TIFF file privacy matters during conversion:
- Healthcare — medical imaging devices export as TIFF. Uploading patient images to a cloud converter raises HIPAA concerns.
- Legal — scanned case files and contracts often arrive as TIFF. Converting them without routing through external servers eliminates third-party exposure.
- Creative agencies — client photography and design assets are confidential. Browser-based conversion keeps files on agency devices.
- Freelancers — NDAs with clients often cover files sent to or processed by third parties. A local converter removes the question entirely.

Does this converter upload my TIFF files to a server?
No. All processing runs inside your browser on your own device. To verify this yourself, open your browser's network inspector (F12 > Network tab) while converting — no file upload requests will appear.
Is it safe to use with confidential or client images?
Yes. Because files never leave your device, there is no third-party server receiving your data. For strict compliance environments, verify with your organization's data handling policy, but the no-upload architecture removes the primary privacy risk of cloud-based converters.
Does PNG output stay lossless even in the browser?
Yes. PNG is a lossless format and the browser conversion process preserves every pixel. The output PNG is identical to what a desktop application would produce from the same source TIFF.
