How JPG to WebP conversion works in MiniFiles
- Processed on your device. Compressor.js re-encodes each photo with your browser's own WebP encoder. Nothing is uploaded.
- Smaller files. WebP is typically 25–35% smaller than JPEG at similar visual quality, which helps pages load faster.
- Your choice of quality. 80% by default, adjustable from 10% to 100% on every plan. EXIF data such as GPS location is removed by default.
- Size cap. Photos larger than 4096 pixels on either side are scaled down to fit; custom dimensions are a Pro feature.
- Free to use. WebP conversion is free on every plan. Without an account you can convert 10 files a day; a free account removes the daily limit. No file size limit.

Frequently asked questions
Does MiniFiles upload my JPGs to convert them?
No. The conversion runs entirely in your browser, so your photos never leave your device.
Is WebP better than JPG?
For websites, usually yes: WebP files are typically 25–35% smaller than JPEG at similar quality, and every current browser supports them. JPEG is still the safer choice for email attachments and older software.
Will converting to WebP reduce quality?
WebP conversion is lossy at the Quality setting you choose. At the default 80% most photos look the same on screen; raise the slider if you need more detail.
Can I convert many JPGs at once?
Yes. Drop a batch of files and each one is converted to WebP. Without an account you can convert 10 files a day; a free account removes the daily limit. No file size limit.
Is JPG to WebP conversion free?
Yes, WebP output is free for everyone. Converting to JPEG or PNG and custom resizing are Pro features.
