Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
- 1Tap the file box and choose an image, or drop one onto it.
- 2Move the quality slider; the result updates each time you change it.
- 3Choose JPEG for the widest compatibility or WebP for smaller files on the modern web.
- 4Compare the sizes, check the preview, then download the compressed image.
A typical 3 MB phone photo (4032 x 3024) compressed at 80% quality usually lands in the hundreds of kilobytes as a JPEG, with no visible difference at normal viewing sizes. The exact saving depends on the image: detailed photos compress less than simple graphics, and the tool always shows you the true before and after numbers for your file.
- PNG screenshots with large flat areas often shrink more as WebP than as JPEG; try both and keep the smaller.
- Compression is lossy: fine detail is traded for size. Keep your original if you may need it for print.
- Dimensions are not changed by this tool; use the Image Resizer when you need different pixel sizes.
No. Your browser does the compression itself using its built-in image encoder. The image never leaves your device.
About this tool
The Image Compressor re-encodes JPG, PNG and WebP images at the quality you choose, so photos and screenshots take up less space and load faster on websites, emails and forms with upload limits. You see the before and after sizes and a preview before you download anything.
