- Press Convert. Each row shows the new size, then download single files or the ZIP.
Limits & formats
Up to 20 images per batch, each up to 20 MB and 25 megapixels. JPG has no transparency: transparent areas are flattened onto white. Animated or exotic formats (GIF, HEIC, AVIF, SVG) are not supported in this first version.
Privacy
Your images are decoded and re-encoded locally in this browser tab. YYSI servers never receive your files. Only anonymous usage counters (tool name, success or failure, rough size range) are recorded.
