Public Scope
Supported formats and current limits
This page explains what the live public version of LocalResizer supports today, what each page family does, and which workflows are intentionally out of scope for now.
Supported image formats
- JPEG for photo-heavy compression and target-size workflows
- PNG for graphics and transparent images that need to stay in PNG format
- WebP for modern static image resizing and compression workflows
Current public page types
- Homepage quick tool for compressing by file size or resizing by dimensions
- Target-size pages such as 50 KB, 100 KB, 200 KB, and 2 MB workflows
- Exact canvas pages for the currently live YouTube banner and thumbnail workflows
What the current live pages actually guarantee
Compress pages
They aim for a target file-size budget locally. JPEG and WebP use quality search, while PNG pages keep PNG output and may reduce dimensions if needed.
Resize-to-size pages
They reduce image dimensions toward a smaller file-size budget while preserving the original aspect ratio and keeping already-small files unchanged.
Exact canvas pages
They export an exact output canvas for the live YouTube sizes, keep the whole image visible, and may add padding when the image ratio does not match.
Current limits and unsupported workflows
- Animated GIF workflows are not part of the current public release.
- Video processing is not part of the current public release.
- Target-size workflows are best-effort because exact output depends on the source image.
- The live platform pages do not auto-crop and do not generate alternate social-media safe-area variants.
- All current public workflows are browser-based and do not require an account.
