TIFF to PNG, explained
Export selected or all TIFF pages as PNG for a raster editing or document workflow. PNG avoids JPEG artifacts in scan lettering and line art; it does not preserve a multipage TIFF or replace its original archival data.
Load a TIFF and review the first-image preview.
Keep PNG selected and check whether a multipage warning appears.
Download the PNG and retain the original TIFF for its remaining properties.
Keep scan edges without a new lossy encode
PNG is useful for diagrams, handwriting and text scans when a receiving application cannot read TIFF. It preserves the decoded pixels without JPEG compression. Existing noise, blur and scan artifacts remain unchanged.
One image rather than the complete document
The decoder visits selected TIFF directories sequentially. A multipage scan produces numbered PNGs, which can be downloaded together as ZIP. Select fewer pages to lower memory use.
Transparency depends on the decoded raster
PNG can retain decoded alpha. It cannot reconstruct transparency or layers that the source decoder does not expose. Compare the exported image against the original in a TIFF-capable application when cutout edges matter.
No promise of original precision
A PNG copy from this browser workflow is not a guarantee that original high-bit-depth data, print metadata or embedded profiles survive. Keep professional scanning and color masters in their original format.
Plan for memory and output size
A compressed TIFF can decode into a large raster. Each image is limited to 24 megapixels and 16,384 pixels per side. PNG output can also be large; smaller batches help stay within the 256 MB total output cap.
