Can’t find your answer? Email support@convertflow.cc.
Is ConvertFlow really a one-time purchase?
Yes. You pay $3.99 once and keep it. There is no subscription and no per-file fee. See the pricing page.
Are my files uploaded anywhere?
No. The desktop app converts everything on your own PC, and the free online converter works inside your browser. Your files never reach our servers.
What can I convert?
Video (MP4, MOV, AVI, MKV, WebM, GIF), audio (MP3, WAV, FLAC, AAC, M4A, OGG) and images (PNG, JPG, WebP, BMP, TIFF, ICO).
Can I try it first?
Yes. The free online converter handles a few image and audio conversions every week, so you can see how it works before you buy.
What if I change my mind?
Ask within 14 days and we will refund you in full. See the refund policy.
Which Windows versions are supported?
ConvertFlow runs on 64-bit Windows 10 and Windows 11.
Does ConvertFlow work offline?
Yes. After you activate it, conversions work without internet. The app checks that your license is valid when you are online, and it keeps working for a while if you are not.
How many computers can I use my key on?
One license key works on up to 3 of your PCs.
I lost my license key. What do I do?
Email support@convertflow.cc from the address you used to buy, and we will send it again. Your key was also emailed to you after purchase if email delivery is enabled.
Is there a file size limit?
The desktop app has no file size limits. The free online converter handles images up to 25 MB and audio up to 10 MB.
Does the free converter upload my files?
No. It runs inside your browser, so your files stay on your device.
How many conversions do I get for free?
The free online converter allows 3 conversions per week. After that, download ConvertFlow and buy a license to keep converting without limits.
Will there be updates?
We keep improving ConvertFlow. Download the latest installer from the download page whenever you want to update.
