About this tool
Compress up to 50 images at once — JPG, PNG, WebP, or GIF — and download the results as a ZIP. Saves the tedium of compressing one image at a time when you're prepping a photo gallery, optimising a folder of product shots, or shrinking a batch before email. Runs entirely in your browser, so even unreleased product imagery never leaves your device.
When to use it
- Prepping a photo gallery for a website or blog post
- Shrinking a folder of product photos for an e-commerce upload
- Reducing the total size of an email attachment batch
- Optimising images before adding them to a CMS or static site generator
- Producing web-ready versions of camera or phone photos in bulk
What to expect
Compression typically reduces JPG/PNG sizes by 50–80% with no visible quality loss. Strength can be tuned per batch. Original aspect ratios are preserved. Output ZIP keeps original filenames so you can drop the compressed copies straight into your project structure.
Frequently asked questions
Will image quality drop noticeably?
At normal zoom and on photographic content, no. The compression targets visual data the eye barely notices. For pixel-perfect work (logos with crisp edges, text screenshots), use a lighter setting or stick with PNG.
What's the maximum batch size?
The interface caps at 50 images per batch for performance. For larger jobs, run multiple batches — your browser handles each independently without re-uploading.
Are EXIF and metadata preserved?
By default, EXIF (camera info, date taken, GPS) is stripped during compression to reduce file size and protect privacy. If you need the metadata preserved, you'll need a different tool — most web-prep workflows benefit from stripping it.
