Convert to WebP and compare the result.
WebP can reduce the size of photos and graphics while keeping transparent areas. Start with the default quality, compare fine detail and text, then adjust if needed. Smaller output is not guaranteed, and the place you use the image must accept WebP.
How to convert your images
- Add one image or a batch of JPG & PNG files.
- Choose Convert images. Adjust quality only if needed.
- Compare the previews. Download individual images or the batch as a ZIP.
Your original files stay unchanged. Each result shows its new file size.
Is this lossless WebP?
No. Some detail can be lost, even at 100% quality. Keep the original for future editing.
Will transparent PNGs stay transparent?
Yes. The WebP output retains transparency. Check the preview on its checkerboard background to inspect edges around logos or cut-out images.
Will my photo details and colors change?
Photos are turned the right way up. Camera and location details (EXIF metadata) are removed. Original color and print settings are not kept, so colors may change. Keep the original if those details matter.
Which files and browsers can I use?
Use still JPG & PNG images. Animated images are not supported.
Each image can be up to 25 MB and 24 megapixels, with neither side above 16,384 pixels. Add up to 100 MB at a time. ZIP downloads support up to 64 MB of results; save larger batches individually. These limits help avoid running out of memory.
Some browsers cannot save WebP. If conversion is unavailable, try an updated browser.
