Why use the image compressor tool from Super Utility Hub?
Compress images online for free before sending them anywhere. Oversized photos are the #1 reason web pages load slowly, emails bounce, and upload forms reject files — this tool re-encodes your JPG, PNG, or WebP with the exact quality you choose.
Use the quality slider to find the sweet spot between file size and sharpness, and optionally cap the maximum dimension so huge phone photos shrink to a sane size. The tool shows the original and new file size instantly.

Frequently asked questions
How much can the file size be reduced?
Most photos drop 50–80% at quality 70–80 with no visible difference on screens. Screenshots and PNG graphics benefit most from a JPG or WebP re-encode.
Does compression reduce image quality?
JPEG is lossy by design, so some detail is discarded. At quality 80+ the loss is visually invisible on screens; keep 90+ for print. PNG output stays lossless.
Why does the output format matter?
JPEG is best for photos, WebP combines great compression with modern support, and PNG keeps transparency and pixel-perfect sharpness. Choose via the format option.
Are my images uploaded anywhere?
No. All compression happens locally in your browser with the canvas API — your images never leave your device.
