TIFF to AVIF converter: free, fast and secure
Convert TIFF to AVIF online for free with ConvertKaro. It is fast, private and works on any phone or computer. TIFF scans are large and browsers cannot display them.

What is TIFF?
TIFF is a professional format used by scanners, printers, publishers and photographers. It keeps full quality, can hold several pages and high bit depths, and is ideal for archiving. But TIFF files are large and web browsers cannot display them, so they are usually converted to JPG, PNG or PDF for sharing.
What is AVIF?
AVIF is the newest mainstream image format, based on the AV1 video codec. It often makes files 30–50% smaller than JPG and noticeably smaller than WEBP at the same visual quality, with support for transparency, HDR and wide colour. Modern browsers display AVIF, but many desktop apps, older phones and upload forms still cannot open it.
When should you convert TIFF to AVIF?
- Hero images and banners on modern websites
- Image-heavy apps where every kilobyte counts
- Next-generation e-commerce catalogues
- Testing the best possible compression
Tips for the best AVIF results
- For websites, 75–85% quality is usually the best balance between size and sharpness.
- You can convert many TIFF files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original TIFF files until you have checked the converted AVIF images.
How TIFF to AVIF keeps your photos and images private
Most online converters upload your file to their server, process it there and send it back. That costs time, uses your data pack and means a copy of your file sits on someone else’s computer. TIFF to AVIF works differently: the page loads the tool into your browser, and your photos and images are processed by your own phone or computer. The file never travels over the internet, so it cannot be leaked, stored or misused.
Using TIFF to AVIF on your phone
TIFF to AVIF is designed for small screens. Buttons are large, options are simple, and downloads save directly to your phone storage. On iPhone, downloaded files appear in the Files app under Downloads; on Android they go to the Downloads folder.
