Unlike JPG (lossy) or PNG (lossless but compressed), TIFF supports:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Lossless compression<\/strong> (LZW, ZIP) or <strong>uncompressed<\/strong> storage<\/li><li><strong>Multiple pages<\/strong> in a single file (rare in JPG\/PNG)<\/li><li><strong>High bit depth<\/strong> (up to 16 bits per channel integer; 32-bit floating point for HDR \/ scientific imaging)<\/li><li><strong>Color profiles<\/strong> for accurate reproduction<\/li><\/ul>\n\n\n\n<p>A typical office scan at <strong>600 DPI in 24-bit color<\/strong> produces ~5 MB per letter-size page. Multiply by 10 pages = 50 MB. The same scan at <strong>300 DPI grayscale<\/strong> would be ~700 KB per page = 7 MB total. The size hit is largely about resolution and color depth, not just the file format.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"compress-vs-convert\">Compress TIFF or convert to PDF\/JPG?<\/h2>\n\n\n\n<p>Three viable paths:<\/p>\n\n\n\n<p><strong>1. Compress TIFF in place<\/strong> (keeps TIFF format)<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Pros: format compatibility maintained, lossless compression preserves quality<\/li><li>Cons: limited size reduction (typically 20\u201340%), still TIFF-format issues for some recipients<\/li><\/ul>\n\n\n\n<p><strong>2. Convert to PDF<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Pros: universal recipient compatibility, multi-page support, dramatic size reduction (often 5\u201310\u00d7)<\/li><li>Cons: format change, slight quality loss with JPG-encoded PDF<\/li><li><strong>Best for:<\/strong> legal docs, contracts, multi-page forms<\/li><\/ul>\n\n\n\n<p><strong>3. Convert to JPG<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Pros: smallest files (often 10\u201320\u00d7 reduction)<\/li><li>Cons: lossy, single-page only (multi-page TIFF becomes multiple JPGs), no archival value<\/li><li><strong>Best for:<\/strong> single-page scans, web display<\/li><\/ul>\n\n\n\n<p><strong>For email of multi-page documents, Path 2 (TIFF \u2192 PDF) wins almost every time.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1600\" height=\"1222\" src=\"\/blog\/wp-content\/uploads\/2026\/05\/step-01-tool-22.png\" alt=\"TIFF compressor showing the file extension dropdown and compression options\" class=\"wp-image-488\" srcset=\"\/blog\/wp-content\/uploads\/2026\/05\/step-01-tool-22.png 1600w, \/blog\/wp-content\/uploads\/2026\/05\/step-01-tool-22-300x229.png 300w, \/blog\/wp-content\/uploads\/2026\/05\/step-01-tool-22-1024x782.png 1024w, \/blog\/wp-content\/uploads\/2026\/05\/step-01-tool-22-768x587.png 768w, \/blog\/wp-content\/uploads\/2026\/05\/step-01-tool-22-1536x1173.png 1536w\" sizes=\"auto, (max-width: 1600px) 100vw, 1600px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"cheat-sheet\">Settings cheat sheet<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">TIFF compress (in place)<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"table table-hover\"><thead><tr><th>Setting<\/th><th>Value<\/th><th>Effect<\/th><\/tr><\/thead><tbody><tr><td>Compression<\/td><td>LZW (lossless)<\/td><td>30\u201340% smaller than uncompressed<\/td><\/tr><tr><td>Color<\/td><td>Same as source<\/td><td>No quality loss<\/td><\/tr><tr><td>Output<\/td><td>TIFF<\/td><td>Maintains format<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">TIFF \u2192 PDF (recommended for multi-page)<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"table table-hover\"><thead><tr><th>Setting<\/th><th>Value<\/th><th>Effect<\/th><\/tr><\/thead><tbody><tr><td>Output format<\/td><td>PDF<\/td><td>Universal compatibility<\/td><\/tr><tr><td>Image compression<\/td><td>JPEG quality 85<\/td><td>Visually identical to source<\/td><\/tr><tr><td>Color<\/td><td>Same as source<\/td><td>Preserves color scans<\/td><\/tr><tr><td>Page size<\/td><td>Letter or A4<\/td><td>Standard PDF size<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">TIFF \u2192 JPG (single-page documents)<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"table table-hover\"><thead><tr><th>Setting<\/th><th>Value<\/th><th>Effect<\/th><\/tr><\/thead><tbody><tr><td>Output format<\/td><td>JPG<\/td><td>Smallest file<\/td><\/tr><tr><td>Quality<\/td><td>85%<\/td><td>High visual quality<\/td><\/tr><tr><td>Color<\/td><td>Convert to RGB<\/td><td>JPG doesn\u2019t support CMYK<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"in-place\">Step by step: compress TIFF in place<\/h2>\n\n\n\n<ol class=\"wp-block-list\"><li>Open <a href=\"https:\/\/www.xconvert.com\/compress-tiff\">xconvert.com\/compress-tiff<\/a>.<\/li><li>Click <strong>+ Add Files<\/strong> and pick your TIFF.<\/li><li>The default LZW compression gives the best lossless result.<\/li><li>Click <strong>Compress<\/strong>.

Done.<\/p>\n\n\n\n<p>If the recipient specifically requested TIFF (uncommon, but happens for certain legal\/medical workflows), use Path 1 (compress TIFF in place) \u2014 it\u2019ll get you to ~30 MB, still over Gmail but works for enterprise email systems with higher caps.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"faq\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Will compression reduce text quality?<\/h3>\n\n\n\n<p>LZW lossless compression: no quality change. JPG-encoded PDF at 85% quality: imperceptible for text and most documents \u2014 you\u2019d need to zoom to 400%+ to spot any difference. For very small text (&lt; 8 pt), keep quality at 95% or higher to avoid edge artifacts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Should I keep the original TIFF for archival?<\/h3>\n\n\n\n<p>Yes. Archival policies (legal, medical, government) typically require the lossless TIFF original. The compressed PDF is a \u201cworking copy\u201d for sharing. Don\u2019t replace the source TIFF with the PDF.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I OCR the PDF after conversion?<\/h3>\n\n\n\n<p>Yes \u2014 and it\u2019s often better than OCRing the TIFF directly. PDFs can carry both the image and a hidden text layer. Tools like Adobe Acrobat, ABBYY FineReader, or open-source ocrmypdf can add a searchable text layer to the PDF after conversion. The image quality at 85% JPG is fine for OCR accuracy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What about multi-page TIFFs becoming separate JPGs?<\/h3>\n\n\n\n<p>If you convert a 10-page TIFF to JPG, you get 10 separate JPG files. To send these as a single attachment, ZIP them or use the <a href=\"https:\/\/www.xconvert.com\/merge-image-to-pdf\">merge images to PDF<\/a> tool to combine them into one PDF.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is there a way to convert without quality loss?<\/h3>\n\n\n\n<p>Yes \u2014 use TIFF \u2192 PDF with <strong>lossless<\/strong> compression mode (FLATE-encoded image data instead of JPG-encoded). xconvert supports this in the advanced options. The trade-off: lossless mode produces a larger PDF (typically 50% of source TIFF size, vs 10\u201320% for JPG-encoded). For legal \/ medical workflows where quality is paramount, use lossless.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What about color profile?<\/h3>\n\n\n\n<p>TIFFs from professional scanners often embed an ICC color profile (Adobe RGB, sRGB, ProPhoto). Conversion to JPG or JPG-encoded PDF strips the profile, which means colors render slightly differently on color-managed displays. For document scans this is rarely visible. For photo TIFFs, embed the sRGB profile in the converted output if your software supports it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is my TIFF still big after compression?<\/h3>\n\n\n\n<p>Two common causes: (1) the source TIFF is uncompressed AND high-resolution (600 DPI color) \u2014 the dominant factor is resolution, not compression. Try converting to 300 DPI grayscale equivalent. (2) The TIFF has many pages and even after compression, accumulates. Convert to PDF for dramatic multi-page reduction.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Try it now<\/h2>\n\n\n\n<p>Compress a TIFF with the <a href=\"https:\/\/www.xconvert.com\/compress-tiff\">xconvert TIFF compressor<\/a>.
