Frequently asked questions
Why convert a JPG to PNG?
PNG is lossless, so it avoids the compression artifacts JPG can introduce. It is the better format for editing, screenshots, logos and any image you may re-save multiple times, and it supports transparency.
Can I convert multiple JPGs at once?
Yes. Drop a whole batch and FileFlow converts every JPG to PNG in one go, then lets you download them together.
Will the image lose quality?
No. PNG is lossless, so your converted image keeps all the detail of the original JPG.
Are my files uploaded to a server?
No. FileFlow runs entirely in your browser using JavaScript — your files are read, processed, and saved on your own device and never travel across the internet. There is literally no server to upload to.
Is it really free? Do I need to sign up?
Yes, it is completely free with no account, no email, and no watermark. Lightweight ads keep the tools free for everyone — there is nothing to install and no limits to unlock.
