ImageGarageMost “make this smaller” requests are JPGs from a phone. The file is large because the camera saved a high-quality JPEG, not because you need every last bit of detail for WhatsApp, email, or a form upload.
Use the tool
Open Compress Image, drop the JPG, and leave quality at 80% first. Download and look at faces, text, and sky. If it still looks like the original, stop. If banding or blockiness shows up, go back toward 85–90%.
When 80% is not enough
If a portal caps you at 200 KB or 500 KB, drop quality in 5% steps. Do not start at 30%. That usually ruins the photo before you know whether 70% would have been enough. If the photo is also huge in pixels (for example 4000×3000 for a profile picture), resize first, then compress. Smaller dimensions almost always beat brutal JPEG quality.
PNG and GIF
The quality slider only affects JPG and WebP. PNG compression in the browser is lossless re-encoding; it may not shrink much. Animated GIFs flatten to a still frame. Convert photos to JPG if you actually need a smaller file.
Privacy
Compression runs locally. The file is not uploaded to ImageGarage. Limits: 50 MB per file, 20 files per batch, 40 megapixels.
