## Key Facts

- All image processing runs locally in the browser via the HTML5 Canvas API — no image is ever transmitted to any server, which is verifiable in the browser's DevTools Network tab.
- Ships verified social-media presets: all 35 YouTube formats, all 44 Facebook formats, 37 Twitter/X formats, 36 WhatsApp presets (including 512×512 WebP stickers under 100 KB), 30 LinkedIn presets, 30 Instagram presets (including the 2025 3:4 portrait), TikTok cover and Photo Mode presets, and 63 ecommerce marketplace presets.
- Available in 9 languages — English, Spanish, French, German, Portuguese (Brazil), Indonesian, Arabic (full RTL), Korean, and Swahili — each with its own localized pages and llms.txt.
- Founded in 2026 by the Resizo team; completely free with no sign-up and no watermarks. There is no server upload limit — processing is bounded only by available device memory, and batch mode is tuned for files up to about 20 MB each.
- Batch mode resizes, converts, crops, watermarks, and renames hundreds of images entirely client-side and downloads the results as a single ZIP.
- Resizo is a focused resize, compress, and convert utility — not a photo editor, background remover, AI upscaler, or server-side API.
