When the browser is enough

Private by architecture, not by a deletion promise.

The image is decoded, transformed, previewed, and downloaded inside your browser. The tool scripts contain no file-upload request. Temporary result links disappear with the tab.

When the desktop app is better

Folders and production work need more context.

UtiliVera Image adds HEIC, AVIF, RAW, PDF, CAD, recursive folders, exact-size search per file, output planning, naming, metadata, GPS removal, recipes, watch folders and reports.

Frequently asked questions

Do these tools upload images?+

No. File decoding, transformation, preview, ZIP construction and downloads run in the current browser.

Why does UtiliVera also offer a desktop app?+

A browser is excellent for a small immediate task. The Windows app handles folder structures, mixed professional formats, repeatable settings, metadata policies, output planning and auditable reports.

Are there limits?+

The exact-KB tool handles one file; PNG and WebP conversion and resizing handle up to 20 files and 100 MB per selection. Larger or more complex jobs belong in the desktop app.
