To compress an image, drop your JPG, PNG or WebP files in below, set the quality, and download the smaller versions — free, in your browser, with no watermark.
Shrink images for email, web pages or uploads while keeping them sharp. Nothing is uploaded, there's no sign-up and no watermark.

JPG, PNG, WebP — add as many as you like🔒 Files never leave your device
Drop your JPG, PNG or WebP files into the box above.
Pick a format and drag the slider until the size looks right.
Save each compressed image, or all of them as a ZIP.
Big images slow down web pages, bounce off email size limits and eat phone storage. Compressing them trims the file size dramatically — often by 70–90% — while keeping them looking sharp. PDFNest does it entirely in your browser: the image is re-encoded on your device, so even private photos never get uploaded.
| Format | Best for |
|---|---|
| JPG | Photos — great compression, widely supported |
| WebP | Even smaller than JPG at the same quality (modern browsers) |
| PNG | Logos, screenshots, anything needing transparency |
The single biggest size saver is resizing: a 6000-pixel-wide phone photo doesn't need to be that big for the web. Set a max width (e.g. 1920px) and the file shrinks before compression even kicks in. Need it inside a document instead? Use Image to PDF, or go the other way with PDF to Image.
Drop your JPG, PNG or WebP in above, pick a format and quality, and download the smaller file. It's compressed in your browser — nothing uploaded, no watermark.
Lower the quality slider and use JPG or WebP. The new size updates live, so nudge it until you're under target.
JPG and WebP are lossy, so very low quality softens detail. 70–80% usually cuts size a lot while still looking sharp.
Yes — every image is processed locally and never uploaded.
