Convert archival TIFFs into lossless, browser-friendly PNGs without the file ever leaving your device. First page of multi-page TIFFs is converted.
TIFF earned its place as an archival format because it preserves everything — which is exactly why you should not throw that fidelity away the moment you need a viewable file. PNG is the web-era format with the same promise: lossless compression, full color depth, and support in every browser and editor made this century. Converting TIFF to PNG keeps every pixel of a scanned document or archived photo intact while producing a file that anything can open.
Scanned documents are among the most sensitive files people handle — contracts, IDs, medical records. This converter decodes your TIFF with an open-source decoder running inside a Web Worker in your own browser, then re-encodes it as PNG on the same device. There is no upload step to trust, because there is no server in the pipeline at all. You can queue multiple files, watch each one finish, and download the batch as a ZIP.
Multi-page TIFFs convert their first page, since PNG stores a single image per file.
Choose PNG for text documents, line art, technical drawings, and anything you may re-edit or run through OCR — lossless compression keeps letterforms and fine lines perfectly sharp. Choose TIFF to JPG when the source is photographic and the goal is the smallest possible file. PNG files of detailed photos can be large; that is the price of keeping every pixel.
Yes — PNG stores the decoded image exactly, pixel for pixel. Nothing is approximated or re-compressed lossily at any stage.
No. The TIFF decoder runs inside your browser, so even confidential scans are converted without leaving your device.
The first page is converted. PNG holds one image per file, so a 10-page scan needs its pages exported individually first.
PNG is lossless, so detailed photographic content costs more bytes. For documents and graphics it is usually compact; for photos, JPG trades a little fidelity for much smaller files.
