PNG to TIFF

Both PNG and TIFF are lossless, but they live in different worlds. PNG rules the web; TIFF is the standard of prepress, publishing, scientific imaging and long-term archives. When a layout program, print shop, stock agency or archive asks for TIFF and your artwork is a PNG, this converter makes the switch without losing a single pixel or the transparency.

Transparency as an alpha channel

PNG images often contain transparency: logos, cut-out product shots, interface elements. With “Keep transparency” on, which is the default, the TIFF gets an alpha channel holding exactly the PNG’s transparency, soft edges included. Layout and photo programs place the image with its transparent background intact. If a PNG has no transparent pixels at all, no alpha channel is written, keeping the file simpler and smaller.

Flattening for print

Some printers and RIP software handle alpha channels poorly or ask for flattened files. Switch transparency off and pick a background color; the image is blended onto it and saved as plain RGB. White is standard for print on white paper. For a colored product package, use that color so soft edges blend correctly.

Lossless compression

Deflate compression is on by default. It reduces file size without changing any pixel and is supported by Photoshop, GIMP, LibTIFF-based tools and macOS. For a typical logo or screenshot, the TIFF ends up in the same range as the PNG. Uncompressed TIFF is there for strict specifications; it needs 3 or 4 bytes per pixel.

Multi-page TIFF

Switch on “Combine into one multi-page TIFF” to put every converted PNG into one file, page after page, in list order. This suits document systems, scanned forms, fax gateways and archive deliveries where one file per set is preferred. Pages can have different sizes; each keeps its own dimensions.

Color depth

The converter writes 8 bits per channel in RGB, which matches nearly all PNGs from screens, design tools and screenshots. Prepress workflows that need CMYK convert colors in their own software, usually Photoshop or the RIP, where proper color profiles are applied.

Resolution for print

TIFF files can carry a pixels-per-inch value that layout programs use to size the image. To set a specific value such as 300 DPI without resampling, use the Image DPI Converter after converting. At 300 pixels per inch, a 3000-pixel-wide PNG prints 10 inches wide.

Sizing down large images

“Limit size” scales images by their longest side, handy when an archive or portal has an upload limit. Reduction uses high-quality halving steps before the TIFF is written.

Archiving screenshots and scans

Libraries and companies that keep records for decades often standardize on TIFF, because the format is openly documented and readable by countless tools. Converting PNG screenshots, scanned letters or diagrams to TIFF keeps every detail and fits such policies. Use consistent file names with dates, such as 2026-10-24-invoice-scan.tiff, so the archive stays searchable without special software.

Private by design

Artwork, product photos and scanned documents are processed only in your browser. No file is uploaded, which matters for client work under embargo.

For photos, JPG to TIFF works the same way. To return to web formats, TIFF to PNG and TIFF to WebP convert back, and TIFF to PDF creates a document from multi-page files.
