JPEGmini is a photo compression tool that reduces JPEG file sizes by 60-80% with no visible quality loss. It uses perceptual algorithms to identify and remove image data that human eyes can’t detect, preserving what you actually see while dramatically shrinking file sizes. Photographers and web designers use it to optimize large photo collections for web galleries, client deliveries, and portfolio sites.

How Designers Use JPEGmini
JPEGmini fits into photography workflows where file size matters but quality can’t be compromised.
For Web Portfolio and Gallery Optimization
Export high-resolution photos from Lightroom or Photoshop, then drag them into JPEGmini. The app compresses each image by 60-80% while maintaining visual quality. Upload the compressed JPEGs to portfolio sites, blogs, or client galleries. Pages load 3-5x faster without visible quality degradation. This is crucial for photography portfolios where large images hurt user experience and SEO.
For Client Photo Delivery
Photographers deliver hundreds of edited photos to clients. Compressing with JPEGmini reduces delivery file sizes from gigabytes to hundreds of megabytes, making downloads faster and cloud storage cheaper. Clients get full-resolution images that look identical to uncompressed versions. Use the batch processing to compress entire wedding albums or commercial shoots in minutes.
For Email and Social Media Sharing
Compress photos before attaching to emails (avoiding attachment size limits) or uploading to social media. JPEGmini maintains quality at screen resolutions while shrinking files small enough for fast uploads. The free tier’s 50 images/day is enough for casual social media posting. Pro users process unlimited batches for commercial social media management.
For Lightroom and Photoshop Integration
The Pro version includes plugins for Lightroom, Photoshop, and Capture One. Enable JPEGmini compression during JPEG export, so every photo leaves Lightroom already optimized. This eliminates the separate compression step and integrates optimization directly into your editing workflow.

Choose JPEGmini if: You’re a photographer processing large batches daily, want Lightroom/Photoshop integration, or need desktop software.
Choose TinyJPG if: You need quick web-based compression for occasional images without installing software.
Choose ImageOptim if: You need lossless JPEG optimization on Mac that preserves pixel-perfect quality.
Choose Squoosh if: You want to experiment with different compression settings and modern formats (WebP, AVIF) in a browser.
Getting Started with JPEGmini
A 5-minute workflow to compress photos:
Step 1: Download and install the free version
Visit jpegmini.com and download the free app for Mac or Windows. Install it and launch. The free version compresses up to 50 images per day with the same compression quality as Pro. No account or credit card required.
Step 2: Drag photos into JPEGmini
Drag JPEG files or folders into the app window. JPEGmini processes each photo, showing before/after file sizes and a preview. The app compresses in place (replaces originals) or exports to a new folder (configurable in settings). Watch the savings counter accumulate as it processes your batch.
Step 3: Review compression results
JPEGmini displays how much space it saved (percentage and megabytes). Use the preview slider to compare before/after images. In most cases, you won’t see a difference. If you spot artifacts (rare), adjust quality settings in preferences. Upload the compressed JPEGs to your website, portfolio, or client delivery system.
JPEGmini in Your Design Workflow
JPEGmini slots into the export and optimization stage after photo editing.
- Before JPEGmini: Edit photos in Lightroom or Photoshop, export as high-quality JPEGs at full resolution
- During JPEGmini: Drag exported JPEGs into app for perceptual compression, or use Lightroom plugin to compress on export
- After JPEGmini: Upload optimized JPEGs to web, client galleries, or cloud storage with 3-5x faster load times
Common tool pairings:
- JPEGmini + Lightroom via plugin for automated compression during JPEG export
- JPEGmini + ImageOptim for double compression (lossy JPEGmini first, then lossless ImageOptim for metadata stripping)
- JPEGmini + Dropbox/Google Drive for client delivery with smaller file sizes and faster uploads
- JPEGmini + WordPress for optimizing blog post images before upload to reduce hosting bandwidth
- JPEGmini Server + AWS for cloud-based batch processing of thousands of images
Common Problems (and How to Fix Them)
These issues come up when compressing photos with JPEGmini.
“JPEGmini didn’t reduce my file size much”
Your photo might already be heavily compressed. Check the original file: if it’s under 200KB for a full-resolution photo, it’s likely already optimized. JPEGmini works best on high-quality camera JPEGs or Lightroom exports at quality 90-100. Low-quality JPEGs have little room for improvement.
“I see artifacts or quality loss in the compressed image”
This is rare but can happen with images that have fine details, text, or high-frequency patterns. Adjust the quality slider in JPEGmini’s settings (higher = better quality, less compression). For critical images, use lossless ImageOptim instead. JPEGmini targets perceptual quality, which works for 95% of photos but may not suit every use case.
“The free version only lets me process 50 images per day”
That’s the trade-off for free access. If you need more, upgrade to Pro ($59 one-time) for unlimited processing. Alternatively, batch your work to stay under 50/day, or use TinyJPG (web-based, different limits) or ImageOptim (lossless, unlimited but less compression).
“Can I compress photos already compressed by JPEGmini?”
You can, but you’ll see diminishing returns and potential quality loss. JPEGmini removes redundant data on the first pass. Running it again compresses an already-optimized file, which can introduce artifacts. Compress once, keep the originals, and only re-compress if you have new source files.
“How do I use JPEGmini with my website or app?”
For automated workflows, use JPEGmini Server (available on AWS Marketplace) or integrate the API into your build pipeline. For WordPress or static sites, compress images locally with JPEGmini desktop, then upload. Some CMS plugins (like Imagify or ShortPixel) offer similar compression via cloud services.
“Does JPEGmini work with HEIC or other formats?”
JPEGmini Pro converts HEIC (iPhone photos) to JPEG during compression. It doesn’t support RAW formats (CR2, NEF, ARW) directly. Convert RAW to JPEG in Lightroom or Photoshop first. For video, JPEGmini Pro compresses H.264 and H.265 (HEVC) formats.
