大量の写真をブラウザで一括リネームする方法
Organize messy camera rolls by batch renaming hundreds of photos with sequential numbering, custom prefixes, dates, and clean formatting in seconds.
DSLR cameras and smartphones export photos with cryptic filenames like IMG_9421.JPG or DCIM_0048.JPG. When organizing vacation memories, cataloging e-commerce merchandise, or delivering client photography, sorting through these names is a nightmare.
ILoveImages' Batch Rename tool allows you to rename hundreds of files simultaneously with custom prefixes, sequential numbering, and date tokens right in your browser.
By utilizing modern browser WebAssembly and HTML5 Canvas pipelines, ILoveImages processes every image locally inside your device memory. This eliminates upload bottlenecks, protects your confidential files from third-party server exposure, and provides lightning-fast execution even on high-resolution camera files.

よくある質問 (FAQ)
Does renaming modify the image data itself?
No. The tool updates file headers and names without re-compressing or touching visual pixels.
Can I use these tools completely offline without an internet connection?
Yes! Once you visit ILoveImages or install it as a PWA, all core scripts and WebAssembly modules are cached locally in your browser's service worker, allowing you to edit photos anywhere, even in airplane mode.
Are my uploaded photos or edits stored on any server?
Never. ILoveImages is built with a zero-server-upload architecture. Every pixel calculation occurs strictly in your browser's local sandbox memory.
