Batch Compress Images Without Uploading a Zip
Most “batch compress” sites ask you to upload a zip to their servers. This tool is different: select many images (or drag a whole set) and batch compress images locally. Ideal for product catalogs, event photo dumps, and blog asset folders.
Who Needs Batch Compression?
E-commerce teams
Shrink hundreds of product shots before CMS import.
Bloggers & SEOs
Optimize a post’s image set for Core Web Vitals in one pass.
Photographers
Deliver client previews without 20MB originals.
Support & ops
Compress screenshot packs before ticket attachments.
Recommended Batch Settings
Web product photos: quality 80–85, output JPG or WebP.
Screenshots with text: keep PNG or use WebP; avoid low JPG quality.
Email packs: quality 70–80 JPG so attachments stay under size caps.
Need only PNG-focused defaults? Open Compress PNG. Need privacy messaging for stakeholders? See Compress Image No Upload.
Workflow Checklist
1. Resize oversize dimensions first if images are huge (Image Resize).
2. Batch compress with consistent quality.
3. Spot-check 2–3 results at 100% zoom.
4. Upload to CMS/CDN.
FAQ
How many images can I batch compress?
There is no artificial site quota. Practical limits depend on your device memory. Most laptops handle dozens of multi-megapixel photos smoothly.
Can I mix JPG and PNG in one batch?
Yes. Use Keep Original to compress each type as itself, or force a single output format for the whole batch.
Is batch compression private?
Yes. All files stay in the browser. We do not receive your images for this tool.
Does batch mean zip download?
You can download results per file from the result list. Process the full selection first, then save what you need.
