Batch Image Compressor

Compress images in your browser. Choose the format, quality, and dimensions, then download your optimized files.

Your compressed images will appear here.

Less weight, more room

Reduce image sizes with control over quality and dimensions.

The format that fits

Choose WebP, JPEG or PNG to suit your project.

A batch in one go

Compress multiple images and download them together as a ZIP.

How to compress multiple images at once

Resize and compress a batch before uploading images to your website or using them in a Lottie sequence. No account is needed to compress or download.

Choose your images

Add PNG, JPEG, WebP, or HEIC images. HEIC files from an iPhone are decoded in your browser; very large batches can take longer or use more memory.

Pick the output and size

Choose WebP for smaller web images, JPEG for photos, or PNG when you need lossless output. Set dimensions and keep the aspect ratio to avoid stretching. Quality affects JPEG and WebP; PNG uses lossless compression.

Compare, then download

Run compression and compare the results with the originals. Download individual images or the whole batch as a ZIP. A smaller output is not guaranteed for an already optimized image.

Does this compress Lottie files?

This tool compresses source images, not Lottie JSON. For an image sequence, compress the frames first, then convert them. Processing stays on your device; saving an exported file to your account is optional and uploads that file.
