Free tools FAQ
Are files uploaded when I use the free tools?
The tools process files locally in the current browser. A file is uploaded only if an audio result is explicitly continued into StudioEditor or a logged-in user explicitly saves podcast artwork to a private project.
Do the free tools require an account or credit card?
Most focused tools require no account. The podcast cover art maker requires a free account to download or save artwork. No tool requires a payment card or AI-tool credits.
Which free file tools are available?
The collection includes audio trimming and conversion, podcast cover artwork design, recording and loudness tools, PDF merging and page extraction, image conversion, resizing, and compression.
Do the tools work on phones and tablets?
They work in modern mobile browsers when the device has enough memory for the selected files. Large PDFs, long audio files, and very high-resolution images are more reliable on a desktop computer.
