Frequently asked questions

What happens to my file?

The conversion code reads your selected file locally and does not upload its contents to a conversion server. Downloads remain on your device. Closing the tab ends the session, but does not guarantee secure memory erasure.

Is this tool free?

This PixelReady tool is free to use and does not require an account. Your browser and device resources are used for processing.

Which formats are supported?

JPG, PNG or WebP input; JPG output in resize mode.

What are the file and conversion limits?

One image up to 20 MB and 40 megapixels. Editable width and height are 1–8,000 pixels where offered. Device memory may impose a lower practical limit. Size targets run from 1 KB to 20 MB; a target cannot always be met at fixed dimensions. KB means 1,000 bytes.
