Image Compressor & Resizer
Compress and resize JPEG, PNG and WebP images in your browser. Nothing is uploaded: choose a size and quality, compare, and download.
How it's calculated
Everything happens in your browser: your images are never uploaded, so they stay on your device.
- The image is decoded by the browser.
- If it's larger than the maximum width or height you choose, it is scaled down to fit, keeping its proportions. Images are never enlarged.
- It's drawn onto a canvas and saved again as JPEG, WebP or PNG. For JPEG and WebP, the quality setting trades file size against detail; around 75–85% usually looks the same as the original at a fraction of the size.
Saving again also removes the photo's metadata (EXIF), such as the camera model and GPS location. PNG is lossless, so it ignores the quality setting; it suits screenshots and graphics rather than photos.
Frequently asked questions
Are my images uploaded?
No. The image is processed by your browser and never leaves your device, so it works with private documents and photos too.
Which quality should I choose?
For photos, 75–85% usually looks the same as the original at a fraction of the size. Go lower if you need a very small file, for example for an online form with a size limit.
Does it remove location data from photos?
Yes. Saving the image again drops its metadata (EXIF), including the camera model and GPS location.
