Resize TIFF

How to Resize TIFF Images Online

1. Choose Your TIFF Files: Drag and drop TIFF images onto the page or click "Choose TIFF files" — up to 50 at once. The first photo opens in the editor and the rest line up as thumbnails below it; with two or more photos open, "Add more" adds files to the same batch.
2. Set the New Size: In Resize, type a "Width" or "Height" in pixels or percent — with "Keep aspect ratio" on, the other side follows — or pick a "Size preset" (percent of original, a target height, or a platform size such as an Instagram post). The size applies to every photo in the batch.
3. Pick the Output Format (Optional): "Save as" keeps "Same as original" or saves as JPG, PNG, WebP or another format. For JPG, WebP and AVIF output, the "Quality" slider (40–100) trades file size against detail. Resize, Crop, Rotate and Flip all work in the same session, and "Undo" steps back.
4. Download: Click the Download button, which names the output format (for example "Download PNG"), for one photo, or "Download all (.zip)" for a batch — "Download one by one" saves the files separately. The editor opens TIFF files right in your browser whenever your browser can decode them, so those files are not uploaded. A file it can't decode is either processed on our servers and deleted automatically afterward — the editor says so before you download — or skipped with a note. No sign-up, no watermark.

Why Resize TIFF Images?

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:

• Prepress and print dimensions — A 10x8 inch print at 300 DPI needs exactly 3000x2400 pixels. Drop in a 6000x4800 scan, set width to 3000 px with aspect lock, and the file emerges at the correct dimensions for your imposition software without round-tripping through JPEG.
• Trim massive scan archives — Flatbed and book scanners routinely output 600 DPI TIFFs at 50-200 MB each. Scaling a 9600x7200 page down to 3000x2250 (still 300 DPI for letter-size print) cuts file size by roughly 90%, and the editor saves the result as a lossless Deflate-compressed TIFF.
• Standardize document-imaging batches — Records management, GIS tilesets, medical PACS, and legal e-discovery often require fixed pixel dimensions like 2550x3300 (US letter at 300 DPI). Drop the whole batch in here — up to 50 scans at once — and the same resize settings apply to every file; Compress TIFF is the pick instead when you also need to re-encode or shrink file size, not just resize.
• Prepare for web or email handoff — A 100 MB TIFF won't fit a 25 MB Gmail attachment cap. Resize first, then run TIFF to JPG or TIFF to PNG so the recipient gets a sensibly sized file.
• GIS and remote sensing tiles — GeoTIFF aerial and satellite tiles need to match downstream raster pyramids. Resizing to power-of-two pixel widths (1024, 2048, 4096) keeps tile alignment clean.
• Microscopy, X-ray, and CT export — 16-bit grayscale TIFFs from scientific cameras are saved as 8-bit here (the editor notes it), so resize a copy for previews and keep the 16-bit original for measurement.

TIFF Resize vs Crop vs Compress — Which Tool Do You Need?

Pixel Dimensions for Common Print Sizes (at 300 DPI)

Formula: pixels = inches x DPI. To go the other way, print size (in) = pixels / DPI.

TIFF Compression Quick Guide

This editor has no compression-type setting; the guide below explains the TIFF compression types you may meet in source files and in other tools. If the output must use a specific one, run the result through Compress TIFF.

Frequently Asked Questions

Does resizing a TIFF re-encode and lose quality?

The pixel grid is re-sampled (that's the whole point of resizing), but the TIFF this editor writes is always lossless — Deflate compression, with no other compression choice — so nothing is lost on top of the resampling. Downscaling is effectively free of artifacts; upscaling interpolates new pixels and will look softer. One change to know about: a 16-bit TIFF is saved as 8-bit.

Will my multi-page TIFF stay multi-page after resizing?

The editor works on the first page of a multi-page TIFF. Downloaded without an edit, the file is your original with every page; once you resize it, the saved TIFF holds the first page only, and the editor says so as soon as the file opens ("This TIFF has N pages: an edit here keeps only the first page"). If you need each page as its own file, run TIFF to PNG or TIFF to JPG instead, which split per page.

Does DPI matter when I resize?

DPI only matters for print; screens ignore it and draw by pixel count. This editor sets pixel size, not a DPI value, so work out the pixels you need instead: inches × 300 for photo prints (a 6 × 4 in print = 1800 × 1200 px), about 150 per inch for posters and banners seen from a distance, and the platform's pixel size for web and social. Your print or layout software then sets the DPI.

How do I resize a TIFF for print without losing sharpness?

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).

Can I preserve LZW or Deflate compression on the output?

The editor has no compression-type setting: every TIFF it saves uses lossless Deflate, and you cannot choose LZW or another type here. If the output must use a specific TIFF compression, run the resized file through Compress TIFF, or save as PNG with "Save as" for a lossless file most tools read.

Will the bit depth and color profile survive?

Partly. The editor works in 8 bits per channel and sRGB: 8-bit TIFFs stay 8-bit, but a 16-bit TIFF is saved as 8-bit (with a note). Embedded ICC color profiles are not kept — Adobe RGB and ProPhoto are converted to sRGB, and a CMYK TIFF is saved as RGB (the note at open says "an edit here is saved in RGB"). Grayscale stays grayscale, and a 1-bit black-and-white scan stays 1-bit. For prepress files that must stay CMYK or keep their profile, resize in your layout or photo software.

Why is my resized TIFF still huge compared to a JPG?

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.

Does the tool handle BigTIFF (files larger than 4 GB)?

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.

What's the difference between resize-tiff and resize-tif?

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.
