How to Compress Images Without Sending Them Anywhere
Key points
- Online compression often uploads your image
- Processing on-device keeps it local
- Take extra care with photos of people
Images contain faces, places and shooting information. Avoid sending them out needlessly just to compress.
Concerns with upload-type services
Images may be sent to a server and kept for some time. Retention and deletion differ by service.
Compressing on your device
This site compresses inside the browser. Images aren't sent anywhere and no registration is needed.
What about shooting information?
Compressed images are rebuilt in the browser, so information such as shooting location (Exif) is not included.
Good habits
- On shared computers, delete saved images after use
- Check what appears in an image before posting on social media
- Keep the original images
Tools that go well with this
- Crop & Rotate Image: Crop an image to any area or ratio, and rotate it.
- Convert Image Format (JPG, PNG, WebP): Convert images to JPG, PNG or WebP, several at once.
- Photos to PDF: Combine several photos into one PDF in the order you choose. You can rotate, reorder and set a size limit.
