Comprimeer JPG — gratis online, geen upload

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.

JPG comprimeren

  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.

Hoe JPG-compressie werkt in 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, plus stripping EXIF, ICC and XMP metadata to save bytes.

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.

JPG houden vs WebP/AVIF

Blijf bij JPG voor maximale compatibiliteit (e-mail, CMS, print). Vergelijk voor web de WebP- en AVIF-kolommen. Zie JPG naar WebP of comprimeer WebP.

Veelgestelde vragen

Verlaagt JPG-comprimeren de kwaliteit?

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.

Hoeveel kleiner wordt mijn JPG?

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.

Blijven EXIF- en GPS-gegevens behouden?

No. PicBrewery strips EXIF, ICC and XMP on re-encode to keep files small. Keep the original if you need metadata.

Kan ik meerdere JPG's batch comprimeren?

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

Verkleint PicBrewery afbeeldingen?

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