Image Squish compresses and resizes JPEG, PNG and WebP images in batches, right in your browser. Drop or paste images, choose a format, quality and maximum size, and see how many bytes you saved. Because nothing is uploaded, it works for private photos and is fast even on large batches.
How to use Image Squish
Drag images in, pick files, or paste from the clipboard.
Choose WebP, JPEG or PNG, a quality level and a maximum width.
Download each image or the whole batch.
Frequently asked questions
Are my images uploaded to a server in Image Squish?
No. All resizing and format conversion executes inside your browser using Canvas / OffscreenCanvas APIs, so sensitive screenshots and photos stay on your device.
Can I paste screenshots straight from the clipboard?
Yes. Press Ctrl+V (or Cmd+V) anywhere on the page to compress a screenshot immediately.
