Questions

Frequently asked questions

Are my images uploaded?
Nothing is uploaded. Your images are opened, resized and saved by your own browser; they never leave your device.
Is it free?
Yes, with no sign-up, no watermark and no limit on the number of images.
Which format should I choose?
WebP gives the smallest files and keeps transparency; every current browser shows it. JPEG is best for photos where compatibility matters most. PNG is lossless: best for screenshots, logos and graphics with sharp edges.
What happens to transparency when I convert to JPEG?
JPEG has no transparency, so transparent areas are filled with the background colour you choose (white by default).
Can I convert WebP to PNG or JPG?
Yes. Add the WebP files and choose PNG or JPEG. The same works for AVIF, GIF (first frame) and BMP.
