TIFF to JPG: Make Large Professional Images Web-Ready

What Is TIFF?

TIFF (Tagged Image File Format) was developed by Aldus Corporation in 1986 and is now maintained by Adobe. It is the standard format for professional photography, print publishing, medical imaging, scientific imaging, and document archiving. TIFF supports multiple compression types (including no compression, LZW, PackBits, and ZIP), multiple color spaces, high bit depth up to 32 bits per channel, and can store multiple images in a single file.

TIFF vs JPG: Quality vs File Size

TIFF prioritizes image quality above all else. A typical TIFF file from a professional camera is 50 to 100 MB or larger. JPEG achieves comparable visual quality at 1 to 5 MB by using lossy compression. For professional editing workflows, TIFF is the correct choice because it preserves all image data through multiple editing cycles. For web delivery, sharing, and viewing, JPEG is far more practical because of its small file size.

Why Convert TIFF to JPG?

The primary reasons to convert TIFF to JPG are sharing and web use. Most websites cannot efficiently serve TIFF files due to their extreme size. Email attachments and messaging apps have file size limits that TIFF files frequently exceed. Online services like social media platforms, cloud storage interfaces, and e-commerce platforms expect JPEG or PNG, not TIFF. Converting TIFF to JPG makes your professional images shareable and web-deployable.

Common Sources of TIFF Files

TIFF files commonly come from: professional digital cameras shooting in RAW format and then exported to TIFF, flatbed scanners and document scanners that default to TIFF for archival quality, medical imaging equipment (X-ray, MRI, CT scan systems), geographic information systems (GIS), satellite and aerial photography, and professional image editing software like Photoshop when saving master files.

TIFF Compression Types Supported

This converter supports uncompressed TIFF (most common, used by many scanners and cameras) and PackBits compressed TIFF (a simple run-length encoding used by older applications and some printers). LZW and ZIP compressed TIFF files are not supported due to browser security restrictions on the required decompression libraries.

Transparency Note

JPEG cannot represent transparent areas. If your TIFF image contains an alpha channel (transparency), the transparent areas will be filled with white when converting to JPG. This is a fundamental limitation of the JPEG format. If you need to preserve transparency, use the TIFF to PNG converter instead.

How to Convert TIFF to JPG

  1. Select your TIFF file — click the upload area or drag and drop your .tif or .tiff file.
  2. Preview — the image is decoded and displayed using a custom JavaScript TIFF decoder.
  3. Click Convert to JPG — compression runs instantly in your browser.
  4. Download — save the JPEG file, dramatically smaller than the original TIFF.

Frequently Asked Questions

What is TIFF format?

TIFF (Tagged Image File Format) is a flexible, high-quality raster image format widely used in professional photography, print publishing, medical imaging, and document scanning. TIFF supports lossless compression, multiple color spaces, high bit depth, and multiple pages in a single file. TIFF files are much larger than JPEG because they prioritize quality over file size.

Why are TIFF files so large?

TIFF files are large because they are designed for maximum quality. They store image data with lossless compression (or no compression at all), meaning no visual information is discarded. A TIFF from a professional camera or scanner can be 50 to 200 MB or larger, compared to a few MB for the equivalent JPEG.

What TIFF compression types does this converter support?

This converter supports uncompressed TIFF files (the most common type) and PackBits compressed TIFF files. These cover the vast majority of TIFF files produced by scanners, cameras, and professional imaging software.

Is transparency preserved when converting TIFF to JPG?

JPEG does not support transparency. If your TIFF has transparent or alpha channel areas, these will be filled with white in the JPG output. If preserving transparency is important, convert to PNG instead.

Is this TIFF to JPG converter free?

Yes, completely free. No registration, no account, no watermarks, no file size limits. This tool uses a custom JavaScript TIFF decoder so your file is never uploaded to any server.
