Frequently asked questions
Does WebP keep transparent backgrounds?
Yes. WebP supports full alpha transparency, so cut-outs and logos stay transparent.
Is WebP lossless?
WebP can be lossy or lossless. At high quality settings the result looks identical while staying far smaller than PNG.
Is the image converter free?
Yes. It's completely free with no limits on the number of files and no watermark. You don't even need an account.
Are my images uploaded anywhere?
No. Everything runs locally in your browser, so your files never leave your device.
Which format should I choose?
Use JPG for photos, PNG for graphics that need sharp edges or transparency, and WebP or AVIF for the smallest files on websites.
Can I convert iPhone HEIC photos?
Yes. HEIC and HEIF photos from iPhones and iPads are decoded right in the browser and can be saved as JPG, PNG or WebP.
