How to Convert Images Online
1Upload your PNG
Click the upload button or drag and drop your PNG file. Upload up to 10 files for batch conversion or multi-page TIFF assembly.
2Choose TIFF output
TIFF is selected by default. LZW lossless compression is applied automatically.
3Download
Click Convert and download your TIFF file. For multiple files you get a multi-page TIFF or ZIP archive.

Frequently Asked Questions
- Does converting PNG to TIFF lose quality?
- No. Both formats are lossless. Every pixel value, including full alpha transparency, is preserved exactly. The conversion changes only the container format, not the image data.
- Will the file size change?
- Often yes. A lossless TIFF can be larger than the original PNG, because PNG's DEFLATE filtering is efficient for many images while a lossless TIFF may be stored with lighter or no compression. The image quality is identical either way; only the container and its compression differ.
- Does PNG to TIFF preserve transparency?
- Yes. PNG 8-bit alpha channels convert to TIFF unassociated alpha. Semi-transparent pixels are preserved exactly, no thresholding or flattening occurs.
- Can I combine multiple PNGs into one multi-page TIFF?
- Not today. If you upload several PNG files, each becomes its own TIFF and they are returned together in a ZIP, rather than merged into a single multi-page TIFF. To get one multi-page .tiff, combine the separate TIFFs afterward in a tool that writes multi-page TIFF.
- Does TIFF preserve 16-bit PNG color depth?
- Yes. Convertify detects the source bit depth and writes the TIFF at matching depth, 8-bit PNG produces 8-bit TIFF, 16-bit PNG produces 16-bit TIFF.
- Why convert PNG to TIFF instead of keeping PNG?
- Only when a downstream system requires TIFF specifically: prepress printing, archival standards, multi-page document assembly, or color-managed workflows with embedded ICC profiles. For web and general use, PNG is more widely compatible.
- Can browsers display TIFF?
- No. Chrome, Firefox, and Edge do not render TIFF natively. Safari has limited support. TIFF is not a web format.
- Does Convertify handle PNG-8 (indexed color)?
- Yes. Indexed-color PNGs are converted to their equivalent RGB or RGBA representation in the TIFF output, preserving the visual appearance exactly.
- What is the difference between .tif and .tiff?
- There is no difference. Both extensions refer to the same Tagged Image File Format; the three-letter .tif comes from older systems that limited extensions to three characters. The file contents are identical and any TIFF-capable program opens either.
Lossless to lossless: what changes and what stays
Both PNG and TIFF store pixel data without lossy compression, so the conversion is bit-exact for the image content: a 24-bit PNG and a 24-bit TIFF of the same image hold identical RGB values. What changes is the container. PNG uses DEFLATE compression with per-row prediction filters built into the format. TIFF is a flexible container that can be stored uncompressed or with lossless schemes such as LZW or ZIP.
Convertify currently writes a lossless TIFF, so no image detail is lost in the move from PNG to TIFF. The pixels you put in are the pixels you get out.
Transparency: PNG alpha carries over to TIFF
PNG supports a full 8-bit alpha channel, 256 levels of opacity per pixel. TIFF also supports alpha, stored as an extra sample per pixel. The format distinguishes associated (premultiplied) and unassociated (straight) alpha, and most professional software expects unassociated alpha.
Convertify converts the image as-is with libvips, so a PNG with transparency keeps its alpha channel in the TIFF rather than being flattened onto a background. If your downstream tool needs a specific alpha handling or a flat white background instead, flatten the image in an editor before or after converting.
16-bit PNG to 16-bit TIFF
PNG supports 16-bit per channel color (48-bit RGB or 64-bit RGBA), and TIFF supports 16-bit per channel as well. This is one of the practical reasons to convert, because several professional editors (Photoshop, Lightroom, Capture One) handle 16-bit TIFF more smoothly than 16-bit PNG in their import and export pipelines.
Convertify converts with libvips, which carries the source PNG's bit depth through to the TIFF, so a 16-bit PNG stays 16-bit rather than being reduced to 8-bit.
When PNG to TIFF makes sense
Convert PNG to TIFF when a downstream workflow specifically expects TIFF: prepress and commercial printing, where TIFF is a common handoff format for print production; archival systems that mandate TIFF for long-term preservation; and editing pipelines that prefer 16-bit TIFF. TIFF is a faithful, lossless image master. If you only need a web or general-purpose image, PNG is already lossless and smaller, so there is no quality reason to convert.
Converting several PNG files at once
If you upload several PNG files, Convertify converts each one to its own TIFF and returns them together in a ZIP archive. It does not merge them into a single multi-page TIFF: one PNG produces one TIFF. If your workflow needs all images bundled inside one multi-page .tiff (for example for some document or fax systems), combine the individual TIFFs afterward in a tool that writes multi-page TIFF.
How Convertify converts PNG to TIFF
libvips decodes the PNG with its built-in loader, reading the full RGBA data and any embedded color metadata, then writes the image out as a lossless TIFF. The bit depth and alpha channel of the source PNG carry through to the TIFF. Each PNG is converted independently: a single file returns one TIFF, and multiple files return a ZIP of separate TIFFs. The whole pipeline runs server-side in Rust, and uploaded files are removed automatically after processing.
How to open and view a TIFF file
Most web browsers do not display TIFF, so a converted .tiff may not preview in the browser even though it is valid. On Windows, open it with Photos or Windows Photo Viewer; on macOS, use Preview. Cross-platform tools like IrfanView, XnView, and GIMP open TIFF as well, and professional imaging software reads it directly. This is one reason people keep PNG for the web and use TIFF only where a specific tool or print workflow requires it.
