Resize TIFF images by exact pixels or percentage. Lossless quality for professional printing. Free, no watermarks.
TIFF (Tagged Image File Format) was finalized at version 6.0 in June 1992 by Aldus/Adobe and remains the prepress, archival, and scanning workhorse because it can store lossless pixel data with multiple compression options, layers, multi-page documents, and color profiles. Resizing a TIFF changes the pixel grid without leaving the format, which is what professional print, document-imaging, and GIS workflows expect:
| Operation | What it changes | Best for | xconvert tool |
|---|---|---|---|
| Resize | Pixel dimensions (width x height) | Matching print sizes, hitting target megapixels, scaling scans | /resize-tiff |
| Crop | Removes pixels outside a rectangle | Cutting borders, framing a subject, isolating a region | /crop-tiff |
| Compress | Re-encodes with smaller compression footprint | Cutting MB without changing dimensions | /compress-tiff |
| Rotate | Orientation (90/180/270 or arbitrary) | Fixing sideways scans | /rotate-tiff |
| Merge to PDF | Combines multiple TIFFs into one PDF | Multi-page archive delivery | /merge-tiff-to-pdf |
| Print size | Pixels (300 DPI) | Pixels (150 DPI screen) | Typical TIFF size (8-bit RGB, LZW) |
|---|---|---|---|
| 4x6 in (postcard) | 1200x1800 | 600x900 | 4-6 MB |
| 5x7 in | 1500x2100 | 750x1050 | 6-9 MB |
| 8x10 in | 2400x3000 | 1200x1500 | 14-20 MB |
| US Letter (8.5x11) | 2550x3300 | 1275x1650 | 16-23 MB |
| A4 (8.27x11.69) | 2480x3508 | 1240x1754 | 17-25 MB |
| 11x14 in | 3300x4200 | 1650x2100 | 27-38 MB |
| 16x20 in | 4800x6000 | 2400x3000 | 55-80 MB |
| 24x36 in (poster) | 7200x10800 | 3600x5400 | 140-200 MB |
Formula: pixels = inches x DPI. To go the other way, print size (in) = pixels / DPI.
| Compression | Lossless? | Best for | Notes |
|---|---|---|---|
| None | Yes | Maximum compatibility, scientific data | Largest files; raw pixel data |
| LZW | Yes | General-purpose, photos, prepress | TIFF 6.0 extension; near-universal reader support |
| Deflate/ZIP | Yes | 16-bit images, screenshots, flat colors | Often 10-30% smaller than LZW |
| PackBits | Yes | Simple RLE, legacy macOS workflows | Modest compression; very fast |
| CCITT Group 4 | Yes | 1-bit black-and-white scans (faxes, line art) | 10-50x smaller than uncompressed for bitonal |
| JPEG-in-TIFF | No | Photos when size matters more than fidelity | Lossy; not for archival masters |
| ZSTD / WebP | Yes / Optional | Newer libtiff-based pipelines | Limited reader support outside recent libtiff |
The pixel grid is re-sampled (that's the whole point of resizing), but TIFF stays lossless as long as you keep a lossless compression choice — LZW, Deflate, PackBits, CCITT Group 4, or None. Downscaling is effectively free of artifacts; upscaling interpolates new pixels and will look softer. If you pick JPEG-in-TIFF as the output compression, that step is lossy regardless of the resize.
TIFF supports multiple pages (image file directories) per file. Our resizer reads multi-page input and applies the same dimensions to every page, writing all pages back into a single TIFF. If you need each page as its own file, run TIFF to PNG or TIFF to JPG instead, which split per page.
300 DPI is the prepress standard for handheld prints — at typical viewing distance, the human eye stops resolving individual dots around that density. Large posters viewed from a distance are routinely 150-200 DPI. Screen-only TIFFs (web preview, documentation) only need 72 or 96 DPI. DPI is a metadata tag in TIFF — it does not change pixel count; you set it alongside dimensions when matching a physical output size.
Decide your final print size and DPI first, then scale to those exact pixels. Example: an 8x10 in print at 300 DPI = 2400x3000 px. If your source is larger, downscale to that target — sharper than letting the printer's RIP scale it. If your source is smaller, you can upscale but expect softness; consider printing smaller or at lower DPI (200 DPI for matte stock is forgiving).
Yes — pick the same compression type in Advanced Options that your input uses (or any other lossless type). LZW is the safest default for compatibility across Photoshop, Lightroom, Acrobat, ImageMagick, and most prepress RIPs. Deflate often produces smaller files but a few older readers (some early-2000s scanner drivers) don't handle it.
8-bit and 16-bit TIFFs keep their depth through resize. Embedded ICC color profiles (sRGB, Adobe RGB, ProPhoto, CMYK FOGRA/SWOP) are preserved on output so prepress color management isn't broken. CMYK input stays CMYK; grayscale stays grayscale.
TIFF stores far more data than JPEG by design — full bit depth, optional alpha, color profiles, and (with lossless compression) no quantization. A 3000x2400 8-bit RGB LZW TIFF runs 15-20 MB; the same image as JPEG quality 90 is roughly 1-2 MB. If file size matters more than archival quality, resize then convert to JPG or PNG.
Classic TIFF uses 32-bit offsets, capping files at approximately 4 GiB; BigTIFF extends to 64-bit offsets (theoretical limit ~18 EB) for very large satellite, microscopy, or whole-slide images. Most prepress and document-imaging files fit comfortably under the classic limit. For multi-gigabyte scientific scans, desktop tools like libtiff or VIPS are a better fit than a browser session.
None functionally — .tif and .tiff are the same format with two common extensions. Both pages accept either extension; we keep resize-tif as a separate landing page for users who search by the three-letter spelling.
