Compress, resize, or convert multiple images at once
What is the Batch Image Processor?
The batch image processor works like this: it applies resize, compress and convert operations to entire folders at once with per-file reporting. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

Frequently asked questions
Is there a file-count limit?
Browser memory is the limit - a few hundred images per batch is comfortable; split bigger sets.
Which operations can run across a folder?
Resize, compress and convert - combined into one pipeline applied to every file, with a per-file report of sizes and any failures.
Are originals modified?
Never - each processed file is a new download; the originals on your device remain untouched.
