How to Compress Images Without Uploading Them
Learn when browser-based image compression is useful and how local-first tools protect privacy.
Why local compression matters
Browser-based compression is useful when you want to reduce file size quickly but do not want to send private screenshots, drafts or client assets to a remote service.
A local-first workflow is especially helpful for marketing teams, freelancers and developers who handle sensitive media in day-to-day work.
A simple workflow
Start by choosing the smallest format that still matches your needs. WebP is usually a good default for web graphics, while JPEG is still useful for photos.
Preview the result, compare sizes and only then download the output you want to publish.
