TIFF Analyzer - Check TIFF Tags, Pages, Compression, DPI and EXIF

How to analyze a TIFF file

Add your TIFF. Drop one or more TIF or TIFF files into the box, paste one, or try a sample. Large scans are fine - nothing is uploaded.
Read the summary. Pages, size, bit depth, colour model, compression and DPI are in the summary.
Inspect pages and tags. Details lists each page; Structure lists every IFD and data block; Metadata lists EXIF and XMP.
Convert or save. Convert to PNG, JPG or WebP, compress it, or save the report.

TIFF too big to send? Compress TIFF applies lossless LZW or ZIP compression.

Compression	Lossless	Good for
None	Yes	Speed - but huge files
LZW	Yes	General use, every app reads it
Deflate / ZIP	Yes	Best lossless ratio
PackBits	Yes	Simple graphics
CCITT G4	Yes	Black and white fax and scans
JPEG	No	Photos in TIFF

An uncompressed 8-bit A4 scan at 300 dpi is about 25 MB. LZW or ZIP usually halves it with zero loss.

Converting with TIFF to PNG or TIFF to JPG fixes most of these.

Drop it in. The analyzer counts every page (IFD) and lists size, colour and compression for each one in Details.

The DPI line shows XResolution and YResolution. Change it without touching the pixels with the Image DPI Checker.

The Colour line shows the photometric interpretation - RGB, CMYK, greyscale, palette, YCbCr or Lab.

The Compression line names it - None, LZW, ZIP, JPEG, PackBits, CCITT G3/G4 and more - and says whether it is lossless.

Yes. BigTIFF (64-bit offsets) is fully analyzed. The preview needs the first page to fit in your browser memory.

No. The TIFF is read in your browser and never leaves your device.
