Fantastic and free service! Fantastic and free service with no size limit, unlike other converters. Conversion doesn't affect quality and is always done in good time. Amazing service in comparison to competitors who charge fees!

After trying numerous other translators… After trying numerous other translators and being frustrated beyond belief, I found this product. I was very pleased with ease of use, speed and accuracy. Wish I found this first, plus it is free. Thanks!

$20 to convert one file? Not at Converter.app! I had one file to convert of my wife's funeral service and none of the 'free' ones would do it for less than $20.00 because it was over 1mb. Thank God for Converter.app, they saved my bacon. Hopefully in the future I can donate. Wonderful people and program.

Worked when Adobe and others didn't Really helpful! I tried two other free, online video converters, and Adobe Premiere Pro and Media Encoder to convert my AIVs to MP4s, and none worked. Said file was corrupted. But this one handled the job with ease! So good. Thanks!

I have been looking for such a service for a year I have been looking for such a service for a long time and already doubted and today I was surprised at how easy and how quickly I got what I dreamed of . I uploaded two recordings one came out great the other a little worse but it's a matter of not the best recording quality .

FAQ

Frequently asked questions

Are my files private?

Yes. We use several measures to keep your data private:

  • Transfer: Encrypted over HTTPS.
  • Retention: Files auto-delete within 120 minutes of conversion.
  • Data use: Only for conversion — no selling, no training on your content.
  • Download Links: All download links stay private and unlisted.
Is Converter App free to use?

Yes—there's no sign-up and no watermarks. Generally, we do not apply any limits on file size or the number of conversions. However, in some special cases, we may apply fair-use limits to keep the service fast for everyone.

How do you keep Converter App free?

We operate as an ad-supported public utility. Revenue from advertisements allows us to cover our high server running costs and fund the ongoing development of our enterprise-grade conversion APIs. This model ensures we can provide unlimited file conversion to students, creators, and professionals at no cost, while strictly maintaining our commitment to never sell your data.

Do you keep a copy of my files?

No. We keep files only for the short time needed to complete your conversion and to deliver the result to you.

What file sizes and formats are supported?

We support common document, image, video, audio, and archive formats. You can also submit files larger than 1 GB. Very large files may take longer or require a retry.

Do I have to sign up to use Converter App?

No. Converter App won't ask for any personal information when you use our services. You can use them right away without an account. Drag, drop, and done.
