What it does
The image is re-encoded at the quality setting you pick, and the tool reports exactly how many bytes were saved — or warns you if the new file actually turned out larger than the original.
How to use
- Add an image in JPG, PNG, or WebP.
- Adjust the quality slider.
- Process the file, review the savings, then download.
Features
- A before-and-after size comparison shows the real result.
- A percent-saved indicator makes the trade-off easy to judge.
- Works across JPG, PNG, and WebP without switching tools.
Use cases
- Shrinking a hero image before it slows down a landing page.
- Getting a photo to a size that's easy to email.
- Compressing a batch of images one at a time during a redesign.
Examples
- A 2 MB JPG at 70% quality often shows a noticeable size reduction.
- A PNG with mostly flat colors may barely shrink, since it's already efficient for that kind of image.
Common mistakes
- Re-encoding a PNG rarely helps much, since PNG compression already handles flat-color images well.
- Setting quality too low can blur small text, which matters most in screenshots.
FAQ
Will compression always help?
Not always. A JPG that's already well optimized can even grow slightly if the quality setting is too high for its content.
Is metadata kept?
Exporting through canvas typically strips EXIF metadata, so location and camera details won't carry over to the new file.
Conclusion
See exactly what you're saving before you download — that visibility is what makes compression a deliberate choice instead of a guess.
