Frequently asked questions
Can I process more than one image?
Yes. You can process up to 10 images in one batch.
Will the result be smaller?
JPG and WebP can be compressed to a file-size limit. PNG encoding is lossless, but meeting a small limit may reduce pixel dimensions. A converted PNG may be larger than the original, and this tool does not preserve transparency. Keep your original and check the downloaded image before uploading.
Is WebP good for websites?
Use the tool to create a download-ready file, then check the result against the requirements of the website or service where you will upload it.
