Why compress your images?
Large image files slow down websites, eat up storage, and make email attachments bounce. Compressing them reduces the file size — often by 60–80% — while keeping the picture looking sharp. Smaller images mean faster-loading pages (better for SEO and your visitors), lower hosting bills, and easier sharing.
Unlike most online compressors, Imagloo never uploads your files. Everything runs locally using your browser's built-in image engine, so your photos stay completely private and there are no size or quantity limits.
Frequently asked questions
Is it really free?
Yes — unlimited images, no account, no watermark.
Do you upload or store my images?
Never. All compression happens on your device in the browser. Nothing is sent to a server, so your images stay private.
Which formats are supported?
JPG, PNG and WebP. You can also convert between formats for smaller files.
Will my image lose quality?
You decide. At 75% quality most photos are visually identical to the original while being far smaller. Lower the slider for tiny files, raise it for maximum fidelity.
Is there a file-size limit?
No fixed limit. Very large files (50MB+) depend on your device's memory, but typical photos compress instantly.
