Frequently asked questions
How much smaller will my JPEG get?+
It depends on the source image and the quality you pick — photographic images with lots of detail compress less than simple graphics. Try 70–80% quality as a starting point.
Does compressing change the image dimensions?+
No — this tool only affects file size and visual quality, never the pixel dimensions. Use the Resize tool if you also want smaller dimensions.
Is this a lossy or lossless process?+
Lossy — you're trading a small amount of visual quality for a smaller file, controlled entirely by the quality slider.
Is there a maximum file size?+
There's no fixed upload limit — Orbfile isn't uploading anything. The practical ceiling is your device's own memory, which comfortably handles even large, high-resolution photos.
How do I compress a JPEG?+
Drop your JPEG into the box above and drag the quality slider — the estimated output size updates live, and your download is ready the moment you're happy with the tradeoff.
About JPEG
Full-size JPEG exports are often much larger than they need to be for how they're actually used. Compression finds a smaller file size that still looks (or sounds) right for the screen, feed, or inbox it's headed to.

Download the result
Your browser processes everything locally and hands you a download link the moment it's done — nothing was ever sent to a server.
Is it private?
Everything happens locally, inside this browser tab. Your image is read from disk, processed with WebAssembly running on your own device, and handed back to you as a download — it's never transmitted anywhere, so there's nothing to intercept and nothing stored on a server.
