Comprimă JPG — gratuit online, fără 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.

Cum comprimi 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.

Cum funcționează comprimarea JPG în 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.

Rămâi pe JPG vs WebP/AVIF

Rămâi pe JPG pentru compatibilitate maximă (email, CMS, print). Pentru web, compară coloanele WebP și AVIF. Vezi JPG în WebP sau comprimă WebP.

Întrebări frecvente

Comprimarea JPG reduce calitatea?

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.

Cu cât va fi mai mic JPG-ul?

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.

Supraviețuiesc datele EXIF și GPS?

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

Pot comprima mai multe JPG în lot?

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

Redimensionează PicBrewery imaginile?

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