Compressing JPG to Under 100 KB
Why JPG is the format of choice for photographs
JPG (JPEG) uses lossy compression built on the discrete cosine transform, which discards the visual data the human eye is least likely to notice — subtle color gradients and high-frequency detail. That makes it uniquely efficient for photographs and complex, full-color images, where it routinely reaches files 50–80% smaller than PNG at near-identical appearance. The trade-off is permanent: each re-save at a low quality level compounds artifacts, so JPG is best treated as a final-delivery format rather than an editing master.
The quality slider: finding your sweet spot
JPG compression is governed by a single quality value. Settings between 70 and 85 typically deliver the best balance for the web — file sizes drop sharply while artifacts stay below the threshold of visibility. Below 70, blocking and banding become apparent; above 90, file size balloons with almost no perceptible gain. For thumbnails and previews you can push lower; for portfolio prints, stay high. A live preview lets you compare quality levels side by side before committing.
Private, instant, and unlimited — entirely in your browser
Every image is decoded and re-encoded locally with the browser's native Canvas and WebAssembly pipeline, so nothing is uploaded to a server. There is no per-file fee, no queue, and no cap on how many photos you can process. That makes batch-optimizing a photo library or a product catalog practical on your own machine, with the speed of your CPU and the privacy of local processing.

Veelgestelde vragen
Why do my JPEGs get worse each time I re-save?
JPEG is generational-lossy: each re-save discards more data. Always compress from the original source file, not from an already-compressed JPEG.
What is chroma subsampling and does it hurt quality?
It reduces color detail more than brightness, exploiting how human vision works. At Q80 it is virtually invisible in photos but can soften small red text.
