About JPG Compression

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.

Vanlige spørsmål

Hvordan komprimere JPEG-bilder gratis?

Last opp JPG/JPEG-filen din og juster kvalitetsglidebryteren. Reduserer filstørrelse samtidig som visuell kvalitet opprettholdes.

Hvordan redusere JPG-filstørrelse for nett?

Last opp JPG-en din, still inn kvalitet mellom 70-85 % for nett-optimaliserte bilder, og last ned.

Does JPG compression reduce image quality?

JPG is inherently lossy. At 70–85% quality the loss is virtually invisible, but repeated compression at a low quality level compounds artifacts over time.

What is the best JPG quality setting for websites?

70–85% is the sweet spot for the web — small files with no visible artifacts. 80% is a reliable default for most photographs.

Can I compress JPG without any quality loss?

Truly lossless JPG is not possible, since the format is lossy by design. For lossless needs use PNG or WebP; for photographs, JPG at a high quality setting is the practical choice.
