Free Image Tools
Image resizing, compression, and conversion are handled entirely on your device. Files are read locally, processed in a background worker, and never uploaded anywhere. Original size, output size, saving percentage, dimensions, format, and quality are all shown before you download.

About this category
Image Tools on Toolivaro follow the same standard as every other page on the site: each tool shows its formula or method, its assumptions, a worked example, and its limitations, and every result is computed locally in your browser.
All tools are reviewed on a regular schedule. If a calculation looks wrong to you, use the correction link at the bottom of the tool page — corrections are reviewed by a human and the reviewed date is updated when changes land.
