Questions
Which format should I choose?
WebP for websites (small files, keeps transparency), JPG when you need it to open everywhere, PNG for logos and screenshots that must stay pixel-perfect, and AVIF when you want the smallest files and your audience uses current browsers.
Will converting reduce my image quality?
Converting to JPG, WebP or AVIF trades a little detail for a smaller file. At the default Balanced setting the difference is rarely visible, and the before/after viewer lets you check. PNG is lossless.
Can it convert iPhone photos (HEIC)?
Yes. Drop your HEIC photos and convert them to JPG, PNG, WebP or AVIF. Photo orientation is respected.
Are my images uploaded to a server?
No. Everything happens inside your browser, on your own device. Your images are never sent anywhere, which also means it keeps working on a slow connection once the page has loaded.
Is it really free? Do I need an account?
Yes, it is free and there is no account, watermark or daily limit.
How many images can I convert at once?
Up to 200 at a time. Drop a whole folder, convert them together, and download everything as one ZIP file.
