JPEG, PNG and WebP
Open JPEG, PNG or WebP images and save them as smaller JPEG or WebP files.
Pairs with the other tools
Use it with the Image Resizer or the Image Converter, both free in your browser.
Why compress images
Large image files slow down websites, fill up storage, and get rejected by email attachments, upload forms and job or visa applications with strict size limits. When you compress images, you reduce their file size while keeping it looking as close to the original as possible.
This compressor runs entirely in your browser. Your images are never uploaded, it's free, and there's no limit or sign-up. That makes it a good fit for private files like ID photos for applications, personal pictures and work documents, since nothing leaves your device.
How to compress
- Pick a format. JPEG opens everywhere. WebP usually gives smaller files at similar quality and keeps transparency.
- Set the quality. Higher quality means a larger file. Lower quality means a smaller file with more visible compression. The new size is shown after each run, so you can adjust until it fits a form's limit.
Tips for smaller files
- Resize first. A photo straight from a phone is often far larger than needed. Reducing its dimensions with the Image Resizer cuts the file size the most.
- Pick the right format. JPEG and WebP are good for photos. This tool saves JPEG or WebP, so for logos and screenshots that must stay PNG, resize them instead.
- Try WebP for the web. WebP files are often smaller than JPEG or PNG at similar quality. Use the Image Converter to switch.
Limitations
Compression always discards some information, and very aggressive settings can cause blocky areas, color banding or blurry text. If a file is still too big at a low quality setting, resize the image first.
Compressing a file that is already heavily compressed rarely saves much space and can make it look worse. For the best result, start from the original photo or export rather than a copy that has been shared, downloaded or compressed before.
