Mampatkan JPG — percuma dalam talian, tanpa muat naik

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.

Cara mampatkan 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.

Cara kompresi JPG bekerja di 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.

Soalan lazim

Apakah kompres JPG menurunkan kualitas?

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.

Seberapa kecil JPG saya?

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.

Apakah EXIF dan GPS tetap ada?

Tidak. Pengekodan semula menggugurkan EXIF, XMP, IPTC dan C2PA Content Credentials, termasuk label penjana AI. Profil warna dikekalkan. Buang label AI dan metadata lain.

Bisakah batch-kompres banyak JPG?

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

Apakah PicBrewery mengubah ukuran gambar?

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