Squash shrinks your images on your device. Pick PNG, JPEG or WebP, set quality, resize if you need to, and see the original vs optimized size with exact savings percent before you download.
Because every image is processed in your browser, nothing is uploaded to a server. Shots of contracts, IDs, medical forms or unreleased work never leave your machine — flip on airplane mode and Squash still compresses.
Add the photos or screenshots you want to shrink. They load straight into your browser — no upload, no account, and nothing is sent to a server or kept anywhere.
Choose PNG, JPEG or WebP, drag the quality slider, and resize if needed. You see the original size, the optimized size, and the exact savings percent as you go.
Save each optimized image, or download everything at once as a single .zip. All of it runs on your device, so it works even with wifi off.
No. Squash runs entirely in your browser, so your images never leave your device and are never uploaded, retained, or used for training. You can turn off wifi or go into airplane mode and it still works — proof nothing is being sent.
Yes, there's a free tier you can use with no signup. Pro ($9/mo or $69/yr) unlocks full resolution, batch with ZIP, and unlimited history across all nimbril tools, or you can get just this app for $4/mo.
You can compress and convert between PNG, JPEG and WebP. WebP usually gives the smallest file at the same visual quality, which is great for the web.
It depends on the image and settings, but you control the trade-off with the quality slider and resize. Squash shows the original size, optimized size, and savings percent so you can stop at the sweet spot.
Yes. Add a batch of images, optimize them together, then download each one individually or grab everything in a single .zip.
