Komprimer JPG — gratis online, ingen opplasting

Drop a JPG or JPEG photo into PicBrewery and download a smaller file re-encoded with MozJPEG — no account, no watermark, no upload. Everything runs in WebAssembly inside your browser.

See the JPEG section on the formats hub for codec details.

Slik komprimerer du JPG

  1. Open PicBrewery.
  2. Drag and drop your .jpg or .jpeg file (or several) onto the drop zone.
  3. PicBrewery decodes the JPEG and re-encodes JPEG, PNG, WebP and AVIF in parallel. Compare byte sizes in the results row — the JPEG column is your re-compressed JPG.
  4. Click the download icon on the JPEG cell, or use Download all as ZIP for batches.

Slik fungerer JPG-komprimering i PicBrewery

PicBrewery does not resize or crop images. Compression means re-encoding the same pixels with a modern JPEG encoder (MozJPEG) at tuned quality settings, EXIF, XMP, IPTC and C2PA are dropped; the color profile is kept.

For photos already saved at quality 85–90, a fresh MozJPEG pass at quality 75–80 often yields 10–30% smaller files with no visible difference. Gains are smaller if the source was already heavily optimized.

Behold JPG vs WebP/AVIF

Behold JPG for maksimal kompatibilitet (e-post, CMS, print). For web, sammenlign WebP- og AVIF-kolonnene. Se JPG til WebP eller komprimer WebP.

Ofte stilte spørsmål

Reduserer JPG-komprimering kvaliteten?

Re-encoding JPEG is lossy — each save can add artifacts. PicBrewery defaults to quality settings tuned for size at matching perceived quality. Use the quality slider under Advanced settings if you need a higher bitrate.

Hvor mye mindre blir JPG-en min?

Typical camera JPEGs shrink 10–30% after MozJPEG re-encode and metadata stripping. Drop your file into PicBrewery to see exact byte counts for every output format side by side.

Bevares EXIF- og GPS-data?

Nei. Omkoding fjerner EXIF, XMP, IPTC og C2PA Content Credentials, inkludert merker fra AI-generatorer. Fargeprofilen beholdes. Fjern AI-merker og annen metadata.

Kan jeg batch-komprimere JPG?

Yes — up to 1000 files per batch, 20 MB each, with Download all as ZIP.

Endrer PicBrewery bildestørrelse?

No. Compression here means re-encoding only — pixel dimensions stay the same.
