About this tool
Images are usually the heaviest part of a web page, and page speed affects both search rankings and conversions. Most online compressors upload your photos to their servers. This one does everything on your device with the HTML canvas, so it's instant, private and works with confidential images.
Which format?
- WebP — typically 25–35% smaller than JPEG at similar quality; supported by all modern browsers.
- JPEG — universal; best for photos when compatibility matters.
- PNG — lossless; use for screenshots, logos and transparency.
Resizing matters more than quality: a 4000-px phone photo displayed at 1200 px wastes over 90% of its pixels.
Frequently asked questions
Are my images uploaded?
No — processing happens in your browser.
Is EXIF data removed?
Yes, re-encoding through canvas strips metadata such as GPS location.
Why did PNG get bigger?
PNG is lossless; converting a photo to PNG often increases size. Use WebP or JPEG for photos.
