Large photos slow down websites, bounce back from email size limits and eat phone storage. This image compressor reduces the file size of JPG, PNG and WebP images right in your browser. Your image is never uploaded to a server, which makes it fast and keeps private photos private.
How to use it
- Choose an image from your device.
- Adjust quality. Around 70–80% usually looks the same as the original at a fraction of the size.
- Optionally set a maximum width. Resizing a 4000-pixel camera photo to 1600 pixels is often the biggest saving.
- Pick JPG, WebP or PNG and download the result.
Which format should I choose?
- JPG is best for photos and works everywhere.
- WebP is a modern format that is typically 25–35% smaller than JPG at similar quality. All current browsers support it, which makes it ideal for websites.
- PNG is lossless and supports transparency, so it suits logos, screenshots and graphics with sharp edges. The quality slider does not shrink PNGs; resize them instead, or convert photos to JPG or WebP.
Why image size matters for websites
Images are usually the heaviest part of a web page. Google uses page speed signals such as Largest Contentful Paint in its ranking systems, and visitors on mobile data leave slow pages quickly. Compressing images before uploading them is one of the easiest speed improvements you can make.
Frequently asked questions
Are my images uploaded anywhere?
No. Compression uses the HTML canvas in your browser. The image never leaves your device.
Why did my file get bigger?
If the original was already well compressed, re-saving at high quality or converting to PNG can increase the size. Lower the quality or choose JPG or WebP.
Does it keep photo metadata?
No. Location, camera and other EXIF data are removed, which is good for privacy when sharing photos online.
