What’s new
Version 1.2 · Updated August 22, 2026
Lossless TIFF output and a new settings page. IMAGE FORMAT • Captures are now saved as TIFF by default — lossless, and the standard format for densitometry and band quantification in ImageJ, Fiji, and similar tools. PNG and JPEG are also available. • Capture settings are written into each file's EXIF and TIFF tags, so your acquisition parameters travel with the image. • The on-image settings stamp can now be turned off, leaving every pixel untouched for measurement. SETTINGS • A new settings page for choosing your image format and controlling the metadata stamp, with links to support, the privacy policy, and the website.
