Scanners commonly output TIFF files — the format preserves full scan quality without compression. Converting a scanned TIFF to PNG gives you a lossless, web-compatible file that opens anywhere. This browser-based converter handles the conversion locally: no upload, no server, scanned documents stay on your device.
Why scanners output TIFF files
TIFF is the default format for professional and office scanners for a simple reason: it stores every pixel without compression artifacts. A scanned document in TIFF captures the full detail of the scan — fine text, thin lines, gradients in photographs — without the blocking or blurring that JPG compression introduces.
The trade-off is file size. A single scanned page at 300 DPI in TIFF can be 20–80MB. A multi-page scan becomes very large quickly. PNG gives you the same lossless quality in a significantly smaller file — typically 30–60% smaller than TIFF for the same content — while remaining compatible with every document viewer, browser, and image application.

Single-page TIFFs — convert directly to PNG with no extra steps. Drop the file in, download the PNG.
Multi-page TIFFs — scanners and fax machines sometimes produce multi-page TIFF files containing several pages in a single file. The converter extracts the first page and converts it to PNG. If you need all pages, split the multi-page TIFF into individual page files first using GIMP or a dedicated TIFF splitter, then convert each page separately.
Very large scans — high-resolution scans (600 DPI+) produce large files. The browser converter processes in local memory with no imposed size limit. Very large files (200MB+) may take 15–30 seconds on older hardware; modern devices handle them in 5–10 seconds.
Privacy matters for scanned documents
Scanned documents are among the most sensitive files people handle — tax forms, medical records, legal contracts, financial statements, and identification documents. Uploading them to a cloud converter creates third-party access to that content, even temporarily.
The browser converter never uploads your files. The scan is read by your browser, converted locally, and downloaded to your device. No third-party server receives the document data at any point. For sensitive scanned content, this is the only approach that keeps your documents truly private.

Open Free TIFF to PNG ConverterFrequently Asked Questions
Can I convert a multi-page scanned TIFF to PNG?
The browser converter extracts the first page from a multi-page TIFF and converts it to PNG. To convert all pages, split the TIFF into individual page files first using a tool like GIMP (File > Export As for each layer) or a dedicated PDF/TIFF splitter, then convert each page separately.
Will the text in scanned documents stay sharp after conversion?
Yes. PNG is lossless — the output preserves every pixel from the source scan exactly. Text sharpness, fine lines, and document detail are identical between the TIFF and the PNG. There is no compression degradation in the output.
How large a scanned TIFF file can I convert?
There is no file size cap imposed by the converter. Processing runs in your browser memory, so the practical limit is your device's available RAM. Files up to 300–400MB convert without issues on devices with 8GB+ RAM. If conversion stalls on a very large file, close other browser tabs to free up memory.
