Does it convert every TIFF page?
No. Only the first page of each TIFF is decoded and converted to PNG.

How to convert TIFF to PNG
01
Add TIFF or TIF files
Choose one or more files; each accepted TIFF begins processing immediately.
02
Wait for TIFF decoding
The converter reads the first image page and produces 8-bit RGBA pixels.
03
Encode as lossless PNG
The decoded pixels are optimized and stored without lossy compression.
04
Download the results
Save one PNG at a time or package multiple completed files in a ZIP.
What the converter actually does
First page only
Extra pages in a multi-page TIFF are not converted.
Lossless PNG encoding
The 8-bit RGBA decoder output is optimized without lossy compression.
No quality setting
PNG uses a fixed optimization level instead of a quality slider.
Batch workflow
Every accepted TIFF is tracked as its own PNG result.
Individual or ZIP
Download one result directly or bundle multiple completed files.
Metadata is not copied
TIFF tags, profiles, layers and higher bit depth are not transferred.
Common TIFF-to-PNG mistakes
Expecting every TIFF page
Only the first page is processed.
Calling the entire conversion pixel-identical
Decoding normalizes the source to 8-bit RGBA before lossless PNG encoding.
Looking for a quality slider
PNG has no lossy quality control in this component.
Assuming PNG must be smaller
File size depends on source compression and pixel content.
Adding too many large scans
Batch work can exhaust browser memory.
Expecting TIFF metadata
The output is encoded from pixels rather than copied TIFF structures.

Frequently asked questions
Is PNG output lossless?
PNG encoding is lossless for the 8-bit RGBA pixels produced by the TIFF decoder. That does not preserve higher source bit depth, TIFF tags or color profiles.
Is TIFF transparency preserved?
The decoder produces RGBA pixels and the PNG optimizer keeps alpha data, but exact results depend on how the source TIFF stores transparency.
Why is there no quality slider?
PNG uses lossless compression, so this component applies a fixed optimization pass rather than a lossy quality value.
Can I batch convert TIFF files?
Yes. Accepted files are converted separately and can be downloaded individually or together as a ZIP.
Will PNG always be smaller than TIFF?
No. Size depends on the TIFF compression and image content. A PNG may be smaller, similar or larger.
Why can a TIFF fail?
Corrupt data, unsupported TIFF variants or compression, very large dimensions and browser memory limits can cause failure.
Are my files uploaded?
No. TIFF decoding and PNG WebAssembly optimization happen locally in your browser.
