Smaller SizeBetter Quality

Binary-search quality so output stays under this size. Ignored if Off.

Resize so longest edge does not exceed this (smaller pixels → smaller file). Uses stepped downscale to keep image sharp.

Auto = only when noise detected. On = always. Off = never.

Lower = preserve detail, higher = smoother (can soften image).

JPG Compressor

Reduce JPG file size in your browser. Free, no upload. Client-side only.

JPG (JPEG) is already a compressed format, but you can reduce file size further by lowering quality. Compressing JPG is useful for web, email, or storage—you balance size and visual quality. Our tool runs in your browser; images are never uploaded. You can process multiple JPGs at once.

When to use JPG Compressor vs other formats

Re-compress JPG when the original was saved at high quality and you can accept a smaller file. Use JPG for photos and realistic images. Use PNG when you need lossless or transparency. Use WebP for web when you want better compression than JPG at similar quality. Use AVIF for the smallest size where supported.

Compatibility

Compressed JPG remains JPG and opens everywhere. Lower quality (e.g. 80%) is often visually fine for web; use higher quality for print or archival. All processing is client-side.

Quality considerations

Each re-encode can add slight artifacts. Don't compress already low-quality JPGs further if you care about detail. Start from the best source and choose a quality level that matches your use (web vs print).

Example use cases

  • Reduce photo size for email or messaging.
  • Shrink JPG for web or app thumbnails and galleries.
  • Create smaller copies for backup or cloud storage.
  • Prepare images for social media upload limits.
  • Batch compress a folder of JPGs for a project or site.

Best practices

  • Use 80–90% quality for web and email to keep images sharp while reducing size.
  • Start from the best source file; compressing an already low-quality image can make it worse.
  • For photos use JPG or WebP; for graphics with transparency use PNG or WebP.
  • Batch compress multiple images with the same settings for consistency. All processing is client-side.
  • Preview before downloading to confirm the result; adjust quality or format if needed.

Common use cases

  • Web and email — Reduce photo and image size for faster page loads, email attachments, or messaging.
  • Social media — Meet upload limits and keep quality good for Instagram, Facebook, and other platforms.
  • Thumbnails and galleries — Create smaller copies for thumbnails, galleries, and app assets.
  • Storage and backup — Shrink images for cloud storage or backup without losing acceptable quality.
  • Screenshots and UI — Compress PNG screenshots or UI assets for documentation and web.
