Compress images for the web without uploading them
How browser-based compression keeps photos private while still cutting file size for faster pages.
Heavy images are one of the most common reasons a site feels slow. Shrinking JPG, PNG, and WEBP files before you publish is still the highest-leverage performance win for many pages.
Traditional online compressors often upload every file to a remote server. That is convenient, but it means product shots, portraits, and drafts leave your device even for a quick experiment.
Filvo’s image compressor re-encodes in your browser with Canvas. You adjust quality, optionally convert formats, preview the result, and download — without building a cloud gallery of your uploads.
Start around 70–80% quality for photos, try WebP when your audience supports it, and keep a master original if you will edit again later.
