Slack, CMS uploads and email signatures all benefit from smaller images. Tentaco compresses JPEG and PNG locally — pixels stay on your device instead of transiting TinyPNG or cloud optimizer servers.
Drag a photo, adjust quality, compare before/after, download. Good for screenshots, hero images and batch one-offs when you do not want to install GIMP or pay for API credits.
Cloud compressors often retain uploads for analytics or re-processing. For client photos, ID scans or unreleased creative work, local compression reduces accidental exposure.
