TIFF Resizer

Resize TIFF and TIF images - every page of a multi-page TIFF, by percent, pixels or print size at a DPI - and keep them lossless. Need a different format instead? Try TIFF to JPG or TIFF to PDF.

How to Resize a TIFF Image

  1. Add your TIFF files. Drop one or more .tif or .tiff files into the box - multi-page TIFFs are welcome.
  2. Choose the new size. Use a percentage, a long edge, exact pixels, or a print size in inches or mm at a DPI.
  3. Pick the output. Keep it a TIFF with LZW or Deflate compression, or save PNG or JPG. Keep the DPI or set a new one.
  4. Resize and download. Press Resize. One or two files download directly, three or more come as a ZIP.

No TIFF handy? Press Try a sample TIFF, or grab more test files from the TIFF converters.

Pixels, DPI and Print Size

A TIFF stores pixels plus a DPI value that tells printers how big to print them.

Print size = pixels / DPI. A 2400 x 3000 px scan at 300 DPI prints at 8 x 10 inches; the same pixels at 150 DPI print at 16 x 20 inches, but softer.

Print size150 DPI300 DPI

Letter (8.5 x 11 in)1275 x 1650 px2550 x 3300 px

Use Print size mode and the tool does this maths for you and writes the DPI into the file.

Multi-Page TIFFs

Scanners and fax software often put many pages into one TIFF.

This tool resizes every page with the same settings and writes them back into one multi-page TIFF, in order. Saving as PNG or JPG gives one image per page instead. To see the pages first, open the file in the TIFF File Viewer.

Tips

  • Emailing a scan? Long edge 1700 px and JPG keeps text readable at a fraction of the size - or use TIFF to PDF.
  • Smaller TIFF without resizing: Compress TIFF re-saves with better compression.
  • For the web: TIFF to WebP or TIFF to PNG - browsers cannot show TIFF.
  • Check the details - compression, bit depth, DPI and tags - with the TIFF Analyzer.

Frequently Asked Questions

Drop your TIFF into the box, choose how to resize - percent, long edge, exact pixels or a print size - and press Resize TIFF. The preview shows the first page at the new size, and the real file size.

Yes. Every page is resized and saved back into one multi-page TIFF. If you pick PNG or JPG, each page becomes its own image, and three or more files come as a ZIP. Need a PDF? Use TIFF to PDF.

Choose Print size, type the width in inches, cm or mm and pick the DPI. The tool works out the pixels (8 in at 300 DPI = 2400 px) and writes that DPI into the file, so print software uses the right size.

Shrinking keeps the image sharp, and TIFF output stays lossless (LZW or Deflate). Enlarging cannot add detail - for that, try the Image Upscaler. Lanczos resampling keeps fine detail crisp when you shrink a lot.

By default the DPI value is kept, so the print size changes with the pixels - the guard under the settings shows the old and new print size. You can also set a new DPI such as 72, 150 or 300.

LZW is lossless and opens everywhere - the classic choice. Deflate is lossless and usually smaller. None is for old scanners and fax software that cannot read compressed TIFFs. For the smallest TIFF, see Compress TIFF.

Uncompressed, LZW, Deflate (ZIP), PackBits, JPEG and CCITT fax TIFFs in 1, 8 or 16 bit, grey, palette, RGB, RGBA and CMYK. JPEG 2000 compressed TIFFs cannot be decoded in a browser.

No. Your TIFFs are decoded, resized and saved in your browser and never leave your device - handy for scans of private documents.
