# Shansu Tools > Privacy-first browser tools for images, documents, health, finance, and date utilities. Website: [Shansu Tools](https://tools.shansu.com/). All listed tools are browser-first and require no account. Files and calculations stay in the browser for core workflows unless a page explicitly states otherwise. ## Tools - [Fast Photo Editor](https://tools.shansu.com/fast-photo-editor/): Compress, resize, convert common image formats, and prepare US ID-photo dimensions in the browser.

OCR accuracy depends on source quality and language. - [TXT to EPUB Converter](https://tools.shansu.com/txt-to-epub/): Convert UTF-8 or GB18030 TXT files and folders to EPUB3, with ZIP output for batch workflows. Conversion runs locally; chapter quality depends on source structure. - [TDEE Calculator](https://tools.shansu.com/tdee-calculator/): Estimate BMR, daily maintenance calories, cutting calories, and lean-gain targets from age, sex, height, weight, and activity level. Results are estimates, not medical advice. - [Weight Loss Calorie Calculator](https://tools.shansu.com/weight-loss-calorie-calculator/): Estimate calorie deficits, target calories, goal dates, and four-week milestones from TDEE, body weight, target weight, and pace.
