Compress TIFF images in your browser

Scans and print exports arrive huge. We rewrite them as Deflate TIFF, with optional palette reduction, on this device.

TIFF options

Colours 256

256 keeps every colour and stays lossless for screenshots and line art. Drop lower on flat scans to cut the file further. A photograph reduced to 256 colours will band.

Dither Off

Hides banding in gradients by mixing neighbouring colours. Leave it off for flat artwork, where it only adds noise and bytes.

Max width Original

Halving the width quarters the pixel count. Options wider than your image are hidden.

Strip metadata Off

Writes a clean TIFF with no EXIF, ICC or proprietary tags. The pixels and the compression are what remain.

Compress to a target size Off

We search for the highest quality that still fits under your figure, then tell you where we landed.

Speed Fast

Fast writes Deflate once. Smallest also tries PackBits and keeps whichever came out smaller.

PNG is usually smaller

PNG is lossless, reads everywhere, and stores a scan or screenshot smaller than a TIFF of the same pixels. Convert unless a workflow demands TIFF.

How to compress a TIFF

01

Drop the TIFFs

TIFF or TIF, one or a hundred. Nothing is uploaded.

02

Choose colours and width

Leave colours at 256 for a lossless rewrite. Cap the width on oversized scans.

03

Save

You get a valid Deflate TIFF written from scratch.

What is a TIFF file?

TIFF is a container from the late 1980s that can hold almost any raster encoding: uncompressed, PackBits, LZW, Deflate, JPEG, and more. Scanners, print shops and archival workflows still prefer it because the pixels stay exact and the metadata stays rich.

The cost is size. An uncompressed 24-bit scan is width times height times three bytes, every time. PackBits helps on flat regions; Deflate with a horizontal predictor helps more, and that is what this tool writes.

If the file does not have to stay a TIFF, PNG is the honest answer for a scan or screenshot: lossless, smaller, and every browser reads it. For a photograph, JPEG or WebP will be a fraction of the size.

TIFF compression FAQ

Why is my TIFF so large?

Usually because it is uncompressed or only PackBits-compressed. A 2400 by 1600 RGB scan is over 11MB raw. Deflate with a predictor typically cuts that substantially without changing a pixel.

Is TIFF compression lossless?

Deflate and PackBits are lossless. Lowering the colours slider is not: that merges colours on purpose. Left at 256, a screenshot or line-art scan comes back pixel-identical.

TIFF or PNG?

PNG, when the file does not have to stay a TIFF. PNG is lossless, reads in every browser, and is usually smaller than even a well-compressed TIFF of the same pixels. Stay on TIFF when a print workflow or archive demands it.

Which TIFF compressions can you read?

Uncompressed, PackBits, LZW and Adobe Deflate, at 8 bits per sample, RGB or palette. Single-page only. Tiles, multipage stacks, 16-bit samples and JPEG-in-TIFF are refused by name rather than guessed at.

Will the browser show a preview?

Yes. Browsers cannot paint a TIFF directly, so the wipe compare is drawn from a PNG of the same pixels. The file you download is still a real TIFF.

Do my files get uploaded?

No. Decoding and encoding both run in this tab. There is no upload endpoint in the code.
