Technical note

Before you convert SVS to AVIF

SVS is a pyramidal whole-slide image: one file carries the same scanned slide at several magnifications, and the largest level can run past 100,000 pixels on a side. AVIF holds a single flat picture at one resolution. That makes the magnification the decisive choice, because there is no sensible original size to fall back on here: the full-resolution level of a slide scan is larger than most image software will open at all. SVS and AVIF both compress by discarding data, so this is a re-encode rather than a copy. The output is built from already-compressed pixels, and the artefacts of the first encode are carried into the second. Use a high quality setting, and convert from the original whenever you still have it.

Twitch thumbnails keep saving as AVIF and my editing software freaks out. reaConverter swaps them to JPEG instantly. Now I can actually post my ‘🔥HOT TAKES🔥’ without crying over file errors.

Google Photos auto-saved my pics as AVIF files that won’t open anywhere. reaConverter rescued 3 years of memories AND kept the quality. Take that, ‘innovation’!

I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.

FAQ

SVS to AVIF Conversion

What are SVS files?

SVS is an image format associated with Aperio medical equipment, such as microscopes or scanscopes. Though similar with the TIFF format in terms of features, SVS has a lot less compatibility with regular image viewers and tends to have a very large size. SVS files contain multiple images in a predefined order, including a baseline tiled image, a thumbnail, intermediate "pyramid" images (made up of tiles), an optional slide label image etc.

What are AVIF files?

AVIF is a new image format launched at the end of 2020. AV1 Image File Format was developed by the Alliance for Open Media in collaboration with Netflix, Google and Cisco. This format was created to be an open-sourced and royalty-free image format with a super-compression efficiency. Multiple graphics compression tests show that the .avif format outperforms the JPEG, PNG and WebP image formats for its image quality to compressed file size ratio.
