Frequently asked questions
Will compressing reduce image quality?
At high quality settings (80%+), the difference is usually invisible to the human eye while reducing file size by 50–80%.
What image formats are supported?
JPG, PNG and WebP. The output is always a universally compatible JPEG.
Is there a file size limit?
Yes, 25MB per image. This is generous for web and email use.
Does this tool upload my images?
No. Your image is processed entirely in your browser using HTML5 Canvas. It never leaves your device.
Can I compress multiple images at once?
Currently the tool processes one image at a time. For batch compression, you can process images sequentially without reloading the page.
