About
Re-encodes an image as JPEG or WebP at an adjustable quality, entirely in your browser using the Canvas API. Actual savings depend on the source image — this tool shows the real result rather than promising the smallest possible file.
Reduce an image file before publishing it on a website, attaching it to an email, or sharing it online. Choose JPEG or WebP, adjust the quality, and compare the original and output sizes before downloading.
What you can do
- Exports compressed JPEG or WebP images.
- Shows original size, output size, and percentage saved.
- Processes the image locally without uploading the file.
Common uses
- Reduce page weight before uploading a website image.
- Make an attachment easier to send.
- Compare JPEG and WebP output at different quality levels.
Frequently asked questions
Which format should I choose?
WebP often produces smaller files for web use. JPEG remains useful when broad compatibility with older software matters.
Does compression change image dimensions?
No. This tool keeps the original width and height. Use Image Resizer when you also need to change pixel dimensions.
