Image compression — FAQ
Private by design
Everything runs in your browser with the canvas API — no upload, no queue, no server ever sees your photo. That's different from most “free” compressors, which upload your images.
Which format?
WebP is usually smallest, JPEG is the safe universal choice for photos, PNG keeps graphics/text pixel-perfect (but bigger). *HEIC support depends on your browser.
Need exact dimensions?
Use the image resizer to change width/height too.
