Compress Multiple Images
Need to shrink dozens of photos for email, web upload, or storage? Select your files, choose a quality level, and compress them all at once.
Compress Multiple Images Without Leaving Your Browser
Sending large photo sets by email or uploading them to a CMS often means hitting file size limits. Instead of compressing each image individually, this tool lets you select multiple files and process them in a single batch. The result is a lightweight ZIP you can share or upload anywhere.
The tool works entirely client-side. Your photos never touch a remote server, which means zero wait time for uploads and complete privacy. The compression engine converts each image to an optimized JPEG at the quality level you select.
This workflow is ideal for anyone who manages visual content regularly: bloggers preparing posts, store owners updating product catalogs, social media managers scheduling content, or freelancers delivering files to clients.
Fast, Private, and Straightforward
Because everything runs in your browser, compression speed depends only on your device. A modern laptop can process 100 images in about 30 seconds. Mobile devices are slightly slower but still handle typical batches without issues.
The quality slider ranges from maximum compression (smallest files) to near-lossless output (largest files). Four preset buttons let you jump to common settings without guessing. The percentage saved is shown in real time so you can see the impact of each adjustment.
Once processing is done, a single Download All button packages every compressed image into a ZIP. Original file names are preserved, so nothing gets lost or jumbled.

Frequently Asked Questions
Is there a limit on the number of images?
You can compress up to 100 images per batch. For larger sets, run the tool multiple times. Each batch is independent.
Will this reduce the resolution of my images?
No. The pixel dimensions stay the same. Only the encoding quality is adjusted to reduce file size. Your images will look the same at full zoom on most screens.
What file types are supported?
The tool accepts JPG, PNG, and WebP files. All output is JPEG, which offers the best compression ratio for photographs.
Do my images get uploaded anywhere?
No. Everything is processed locally in your browser. Your files never leave your device, and no data is sent to any server.
Can I cancel the compression mid-process?
Yes. A cancel button is available during processing. Already-compressed images are kept, and unprocessed ones are skipped.
How do I get the best quality with the smallest file size?
Start with the Good preset, which balances quality and compression well for most photos. If the files are still too large, move the slider slightly left. If you notice artifacts, move it right. The real-time savings display helps you find the sweet spot.
