Upload up to 60 JPG, PNG, WebP, GIF, BMP, or AVIF images and process them on your device. Resize by preset or custom dimensions, compress with quality controls, convert formats, rename files, preview outputs, and download individual images or a ZIP archive.

How to use this tool

1. Select multiple JPG, PNG, WebP, or GIF files. 2. Pick a compression level and output format. 3. Click Compress all. 4. Review per-file size savings in the results table. 5. Download the ZIP archive with every compressed image.

Worked example

Example: eight product JPGs totaling 18 MB compressed at medium quality might shrink to about 4 MB in one ZIP—ready to upload to a storefront or email.

When to use this

Preparing a product catalog folder before upload.
Shrinking an entire blog image directory for deploy.
Uniform compression across team headshots.
ZIP download of optimized assets for a client handoff.

Common examples

Eight 3–5 MB product photos → one ZIP of WebP files under 500 KB each for Shopify.
Blog image folder before static deploy → batch compress to cut total page weight.
Team headshots for intranet → uniform compression level across 20 portraits.

Common mistakes

Mixing PNG logos and photo JPEGs at one aggressive quality setting.
Not checking a few samples before processing hundreds of files.
Forgetting transparency requirements on icon PNGs.
Skipping resize when dimensions are the main weight problem.

How it works

Upload multiple images, choose a fast web-optimized preset or custom resize, compression, conversion, and rename settings, then process everything on your device. Preview each output, retry individual files, and download one image, all images, or a ZIP archive.
