Convert a TIFF scan to lossless PNG in your browser. Alpha is kept, the orientation tag is applied, and only the first page is written.
The converted PNG appears here.
Your file is never sent to a server. It is read and processed by your own browser, and the results are not stored.
The decoder expands the TIFF page to RGBA pixels. The orientation tag is applied, then the PNG encoder writes those pixels losslessly. Dimensions are unchanged, so a 2400 × 3200 scan stays 2400 × 3200.
The conversion is not a container copy. TIFF tags, layers, private metadata and print-specific colour information do not travel into the PNG. The picture does.
Use PNG for diagrams, text, transparency and anything that will be edited. Use JPG for photographic scans where a smaller file matters more than exact pixels. Both tools run locally and both report the real output size after encoding.
No. TIFF to PNG Converter runs in your browser, and the file is read there rather than sent to a server for processing. Our host still sees ordinary page-request metadata, which is described on the privacy page.
Yes, TIFF to PNG Converter is free, with no paid tier, no account, and no watermark added to your output. The limits are technical rather than commercial: file size, page count and supported formats are listed on this page.
TIFF to PNG Converter supports .tif, .tiff files up to 50MB directly in your browser.
PNG stores every pixel exactly and can keep transparency. It is the better choice for line art, screenshots, maps and images that will be edited again. For a photographic scan that only needs sharing, JPEG will be far smaller.
Yes. If the TIFF page decodes with an alpha channel, the PNG keeps it. Opaque scans remain opaque.
No. The first page is converted and the page count is reported. Converting a multi-page TIFF into several files would be a different tool with a ZIP output.
No. BigTIFF uses a 64-bit layout that the bundled decoder does not read. Re-save it as a standard TIFF or another format first.
