Why use a browser-based compressor?

Most image compressors upload your files to a server, process them, and send them back. That round-trip is slow, uses bandwidth, and means your photos pass through a stranger's machine. Fileoholic's compressor is different — every byte stays on your device. The compression code runs in your browser, in JavaScript, using a Web Worker so your page never freezes.

Drop a 5 MB photo and it shrinks to a fraction of the size in seconds, ready to attach to an email, upload to a portal, or share on social. Quality stays high at 70-80 on the slider. No daily limit, no signup, no nag screens.

Your files never leave your browser.

All processing runs locally on your device. No uploads, no tracking of file content.

FAQ

Are my files uploaded to a server?

No. All compression runs in your browser using JavaScript. Your images never leave your device.

What file formats are supported?

JPG, PNG, and WebP for both input and output. Drop one file or many.

Is there a file size limit?

Each file should be under 30 MB to work reliably on mobile browsers. Desktop browsers handle more.

Why is my PNG only slightly smaller?

PNG is already lossless. For big size cuts, convert PNG to JPG or WebP using the format selector.

Does compression reduce image quality?

Yes, that is how it saves space. Use the quality slider to balance file size and visible quality. 70-80 is usually invisible.
