Why batch compression saves hours
E-commerce sellers, bloggers, real estate agents, and designers all hit the same problem: many large images that need to be web-ready. Manual export from a photo editor works but does not scale.
Batch compression applies the same quality settings to every file, keeps results consistent, and lets you download everything as a zip archive. What took an afternoon becomes a five-minute task.
Consistency matters for user experience. When every product thumbnail loads at a similar speed and quality level, your site feels professional instead of random.

What to look for in a batch tool
Privacy first: tools that upload your files to a remote server expose customer photos, internal screenshots, and personal images to third parties. Browser-based processing avoids that entirely.
Format support: JPG, PNG, and WebP cover most workflows. Check whether the tool preserves transparency for PNG or converts to WebP automatically.
Quality control: a slider or percentage setting lets you balance size and sharpness. Some tools show before-and-after file sizes so you can adjust before downloading.
Zip download: essential when you are processing more than a handful of files. Individual downloads work but slow you down.
Recommended settings for batch jobs
For website galleries, start at 80% JPG quality or equivalent WebP setting. Preview one image, then apply the same setting to the batch if it looks good.
For email newsletters, 70–75% quality and a max width of 1200 pixels is usually enough. Readers will not see full resolution on most screens anyway.
For archival storage where you still want smaller files, use lossless PNG compression or WebP lossless for graphics, and moderate lossy settings for photos. Never batch-compress your only copy of an original — keep masters elsewhere.
Workflow: from folder to optimized zip
Collect all images in one folder on your computer. Open the Irreva Image Compressor in your browser. Drag the entire selection into the upload area or use the file picker to select multiple files.
Set your quality level and output format. Watch the estimated size reduction on the first few files. When satisfied, process the batch and download the zip.
Rename or upload the optimized files to your CMS, shop, or cloud drive. Delete the oversized originals from your web server if they were already published — keeping both wastes storage and confuses future edits.
