TIFF Compressor

Compress TIFF Online — Free, No Watermark

Upload your TIFF, choose LZW or ZIP lossless compression to stay pixel-perfect, or lower the quality / convert to JPEG for a much smaller file, then click Convert. We compress it on our servers — no sign-up, no watermark — and your download is ready in seconds.

Real result: in our production data the median TIFF drops ~84% (an 8 MB TIFF → ~1.3 MB) — TIFF is often uncompressed, so it shrinks dramatically.

How to Compress TIFF Images Online

1. Upload Your TIFF Files: Drag and drop, or click "+ Add Files" to select.tiff or.tif images from your computer. Batch is supported — queue dozens of scans, RAW exports, or multipage TIFFs in one job.
2. Pick a Compression Type: Default is JPEG (lossy, best ratio). Switch to LZW or Deflate (ZIP) for lossless archival, PackBits for legacy software compatibility, CCITT Fax 4 for 1-bit black-and-white scans, or WebP / JP2K / ZSTD for modern codecs. Set "None" only if you want to repackage without compressing.
3. Set Target Size or Quality (Optional): Target file size as a percentage of the original, enter an exact size in KB/MB with Auto Scale, or drive output with Image Quality (%). For lossy modes, 60–80% quality typically halves the file with imperceptible quality loss for photographic content at normal viewing distances.
4. Compress and Download: Click Compress. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared. Output extension can be locked to .tiff or .tif.

Why Compress TIFF Files?

TIFF (Tagged Image File Format) is the workhorse of professional imaging — uncompressed, 16-bit, multi-page, lossless. A single 600 DPI A4 scan can land at 100+ MB, and a RAW-export TIFF from a 45 MP camera routinely exceeds 250 MB. Compression brings those files down without giving up the professional pipeline.

• Email and cloud sharing — Gmail caps attachments at 25 MB; Outlook at 20 MB. LZW or Deflate usually halves an 8-bit scan, putting it under the cap with zero pixel loss.
• Archive thousands of scanned pages — CCITT Group 4 compresses 1-bit (black-and-white) document scans roughly 15:1 with no quality loss, the standard for legal, library, and government archives.
• Stay under the 4 GB classic TIFF ceiling — Classic TIFF uses 32-bit offsets and tops out at 4 GB. Compressing a panorama or microscopy stitch keeps it inside that limit so it opens in Photoshop, GIMP, and Windows Photo Viewer (none of which read BigTIFF reliably).
• Web and CMS uploads — WordPress core blocks TIFF by default and many CMS plugins choke on 50+ MB files. Compress, or convert with TIFF to PNG / TIFF to JPG for direct web use.
• Faster ingest for OCR and DAM pipelines — Tesseract, Adobe Bridge, and most DAM systems re-decode each upload. Halving file size on a 5,000-page batch shaves real hours off the indexing pass.
• Cheaper cold storage — S3 Glacier Deep Archive bills by GB-month. Lossless LZW on a 2 TB scan corpus is a one-time job that lowers the storage bill every month forever.

Frequently Asked Questions

How do I reduce TIFF file size?

Apply LZW or ZIP (Deflate) lossless compression first — both keep every pixel intact and typically halve an 8-bit TIFF. For bigger cuts, convert to JPEG-in-TIFF or lower the bit depth to 8-bit. Uncompressed TIFFs shrink the most; just upload, pick a method, and compress on our servers.

Should I pick LZW or Deflate (ZIP) for my TIFF?

Both are lossless — pixel-identical to the original. For 8-bit images they compress about the same, so pick LZW for maximum compatibility (every TIFF reader since the 1990s supports it). For 16-bit images, Deflate is the safer choice — LZW's dictionary approach can actually enlarge high-entropy 16-bit data, so you'll occasionally see an LZW TIFF that's bigger than the uncompressed original. Deflate is slower to encode but rarely backfires.

Why is my LZW-compressed TIFF larger than the original?

You probably have a 16-bit or very noisy image. LZW builds a dictionary of repeating byte patterns; 16-bit channels carry far more unique values per pixel, so the dictionary balloons and the overhead exceeds the savings. Use Deflate (ZIP) instead, or convert down to 8-bit if the bit depth isn't needed for your output.

Can I compress a multipage TIFF and keep all the pages?

Yes. XConvert preserves the multipage structure — every page in a single.tiff is re-encoded with the compression type you choose and written back to one file. Each page can use the same method, so a 200-page scanned contract compressed with CCITT Group 4 stays one.tiff file, just much smaller. If you want to split or merge pages instead, use Merge TIFF to PDF.

Is CCITT Group 4 only for black-and-white scans?

Yes. Group 4 (ITU-T T.6, standardized in 1988) is a bilevel codec — every pixel is 0 or 1, black or white. It's the gold standard for scanned text, legal documents, line art, and fax-style archives, where it routinely hits 15:1 ratios. If your image is grayscale or color, the encoder will reject CCITT or convert to bilevel first, which usually isn't what you want.

When should I use JPEG compression inside a TIFF instead of just saving as.jpg?

When you need TIFF's container features but want JPEG's size — for example, multi-page document archives where pages are photographic (book scans, photo prints) and the workflow downstream expects.tiff. JPEG-in-TIFF gives you 10–30x compression but is lossy. If you don't need multi-page or extensible metadata, save as JPG directly with our TIFF to JPG converter — smaller header, broader support.

What's the maximum TIFF file size, and does this tool handle BigTIFF?

Classic TIFF uses 32-bit byte offsets and is capped at 4 GB. Files larger than that need BigTIFF, a 2007 specification that swaps in 64-bit offsets and theoretically allows files up to 18,000 petabytes — common in GIS, microscopy, and gigapixel panoramas. BigTIFF support varies by tool; Photoshop, GIMP, and GDAL read it, but Windows Photo Viewer and older browsers do not. For most photo and document work, staying under 4 GB after compression is the safest target.

Will compressed TIFFs still open in Photoshop, Lightroom, and InDesign?

Yes for LZW, Deflate (ZIP), JPEG, PackBits, and CCITT — these are the methods defined in the TIFF 6.0 specification and Adobe's TIFF Technical Notes, and every release of Photoshop, Lightroom, Capture One, and InDesign reads them. WebP, JP2K, and ZSTD inside TIFF are newer and may require an up-to-date plugin or a different viewer; if you're handing files to a print shop or stock agency, stick with LZW or Deflate.

How much can I expect to reduce my TIFF file?

Depends entirely on content and method. Uncompressed 8-bit photographic TIFFs shrink ~50% with LZW and ~60% with Deflate (both lossless). 16-bit RAW exports often see less benefit (10–30%) from lossless methods. Photographic content with JPEG-in-TIFF at quality 75 typically compresses 10–20x. Black-and-white scanned documents with CCITT Group 4 typically hit 15:1 — a 30 MB uncompressed bilevel scan becomes about 2 MB.

Can I compress TIFF and also resize it in one pass?

Yes — set both. Drop resolution to 50% (or pick a preset like 1080P) in addition to choosing a compression type. Halving each dimension cuts pixel count to 25%, so total size reduction stacks: a 16:1 lossless reduction is realistic when you don't need the original print resolution. If you only need to resize and not re-compress, use Resize TIFF.
