A single image tool, not a maze of tiny utilities
The operations share the same queue, preview, settings, and export pipeline. You do not need to reopen the same file on separate pages.
Resize and crop
Keep proportions or use centered square, portrait, landscape, and widescreen crops.
Convert and clean
Create JPEG, PNG, or WebP files without copying source metadata blocks.
Common questions
Are my images uploaded?
No. Selecting, dropping, editing, and encoding happen in the browser. Cloudflare still receives ordinary connection metadata when serving the page.
Does Clean erase every possible trace?
Holi exports newly encoded pixels and does not copy source metadata. The visual pixels can still contain identifying information.
Why is the exported size sometimes larger?
PNG is lossless and photos can grow. JPEG or WebP with lower quality is usually smaller for photography.
