Cost classification: Free resource (core access). Review the provider's current official terms before relying on an offer; separate core free functionality from optional upgrades, accounts, storage or third-party charges.
1. Start with real display needs
Squoosh is a browser-based image compression tool. Decide whether the picture will be a small article card or a full-width hero. Resizing a very large original to sensible dimensions may save more data than extreme quality settings.
2. Compare output formats
Try JPEG, WebP or other formats supported by your audience and publishing tools. Different photographs respond differently to compression, so preview fine text, faces and gradients instead of relying only on a percentage.
3. Inspect privacy and file workflow
Review the official app and its current processing model before handling sensitive imagery. Keep the original outside the export folder; a smaller copy should not silently replace your editable master.
4. Verify in a real browser
Load the result on a phone-sized screen, compare clarity and check the final byte size. Give images descriptive filenames and appropriate alt text when used on a website.
