How to Compress Images
Choose one image, multiple images, or a folder of JPG, PNG, or WebP files.
For batches, set a target size. JPEG and WebP use quality search and resize only when needed.
Preview the result or download the completed batch as a ZIP archive.
Supported Image Formats
Convert and compress JPEG, PNG, and WebP images without sending them to a server.
- JPEG for photographs and everyday images
- PNG for screenshots, graphics, and transparency
- WebP for modern, lightweight web images
Private Browser-Based Compression
Compression happens on your device using a Web Worker. The page only creates a local download, so your image data stays under your control.
Frequently Asked Questions
Are my images uploaded?
No. Images are decoded, resized, and encoded locally in your browser.
Can I convert an image to WebP?
Yes. Select WebP in Output Format to compress JPEG or PNG files as WebP.
Why is my compressed PNG not smaller?
PNG is lossless in this version. Photographs often become smaller as JPEG or WebP.
Can I compress a folder of large photos?
Yes. Batch mode processes a small number of images at once, streams results into a ZIP, and keeps already-small files unchanged.
What happens if one batch file fails?
The remaining files continue. The failed item is marked in the list and can be retried after the batch finishes.
