FAQ
Frequently asked questions
Everything you need to know about image format converter.
Which output formats are available?
WebP, PNG, JPEG, and AVIF are available, in both single-file and batch modes, so you can convert one image or a whole folder.
Which format is best for web use?
WebP offers the best quality-to-size ratio and is supported by all modern browsers. AVIF compresses further but support is newer; JPEG is the safest legacy choice.
Does this work on mobile?
Yes. Everything runs in your browser, so conversion works on phones and tablets with no app install.
Why did my conversion fail?
The browser could not decode the source or encode the target format. AVIF support varies by browser, so try WebP or PNG as a fallback.
Can I convert a batch of files?
Yes. Batch mode converts every file to the selected format and packages the results into a downloadable ZIP archive.
Is my image uploaded?
No. Conversion is done locally on a canvas element, so your images never leave your device at any point in the process.
